Multifunctional complex of actuators on the basis of planetary cycloidal reducer - FEM PCR refers to geared motors, actuators and can be used in precision actuators of robots and manipulators, defense, ground-based and space navigation, machine tools, transport, electric vehicles, hoisting machines and winches, for transmitting rotation in a tight space, in the oil and gas industry. In recent years more and more applications are geared motor (we are talking here and below about the drives), which are mounted in a single package, are characterized by smaller dimensions, a small number of parts, low noise level in the work process and are used mainly in hoisting machines and rigging operations.

Studies of analogues of the invention was opened by famous and original transmission with different profiles gearing. They are characterized by relatively low reliability, resource and adaptability [1-6-10] for operation in various conditions and overload, and lack of self-organization on the formation of gearing and low maintainability. The proposed complex FEM PCR a higher perspective and durability of operation with tons of traffic and high speeds, when without noise the second operational mode. There is a peculiar and original, simple constructional solution of the present invention. Deficiencies and accidents prototype and analogues eliminated in the present invention FEM PCR. So a small area of engagement in counterparts (~1°-5°) significantly expanded mnogozahodnoy and more elastic zone gearing up to 100° or more (figure 2, 3, 5, 6).

The invention FEM PCR improves the reliability, lifetime, transmission efficiency (>95%), according to the characteristics based on the calculation and implementation in the manufacturing of optimum conditions of design and operation, if necessary with grease.

The invention is applicable in the industry and provides a wide selection of the required range of materials, calculation of the promising technologies of production and operation, it has a higher samoorganizuyuschejsya (adapt) [9].

Design FEM PCR provides the best energy saving and reduction of electromagnetic losses in motors and gearboxes drive, it expanded the range of gear ratios (i≥10-1000), analogs and prototypes it is limited. The invention is characterized by a play-free and noiseless operation and exploitation that with minimum dimensions of the actuator and its autonomy is extremely important for rapid deployment in submarines, helicopters and research at the extreme the conditions of the bottom of the ocean and space.

The set of actuators valuable opportunity to save and to take into account the last operation and information that increases its optimality in automatic control systems and regulation (ACS).

The complex drives PCR can be connected and plugged in conventional continuous electric motors, including the built-in special, and also be interfaced with discrete control systems from discrete sensors or computers.

Technical equivalents of the invention is a motor-reducers [1] French, American, Japanese and other firms. For example, the motor-reducer France. Pat. No. 1440594, 1966. Technical prototype of the invention is a motor - reducer of figure 1, as well as other motor-reducers, represent the mechanical connection of the motor - ED and gearbox in one common housing. There is no merging of a number of components and assemblies for the exercise of approximately equal operations, the total number of bearings increases.

The closest in technical essence is the planetary cycloidal reducer development of the Minsk Institute of problems of reliability of the Academy of Sciences of the BSSR, 1988, which is taken as a prototype (figure 1) and includes a housing 10, a cover 12, the input (master) and the output (driven) shaft 4 and 13, the fixed Central (sun) wheel 2 with a number of rollers (coils) 1, cycloidal satellite, 9 block of satellites 8 mounted on the input shaft 4 on the bearings of the shaft 3 and the eccentric bearings located satellites 6, inside the Central wheels 2, 11, cycloidal teeth 8 which engage with the teeth of the Central wheels; the fingers 14, is pressed into the flange of the output shaft (the rolling of the output wheel 11) and freely worn on their rollers 15, incoming engages with 9 satellite unit satellite 8, the rollers (horn) 1 stationary Central wheel 2 and the rollers (pins) 15 output shaft (Central rolling wheel 11).

Satellites 7, 9 blocks of 8 satellites prototype of figure 1 are in constant engagement with the Central wheels 2 and 11 (15'), rigidly fixed respectively in the housing 10 and the output shaft 13. The satellite is connected to the eccentric shaft 5 and an electric motor ED bearings 6 and through the bearings 16 of the output shaft 13 of the rolling wheel 11 (15') is connected with the load. In a similar sequence occurs and the specified prototype.

The disadvantages of the prototype are:

- possible gear ratio range is limited within 7-5000 and may not be adjustable;

- The efficiency of the presented prototype does not exceed 92%;

- gearbox prototype single-stage, non-adjustable;

- limited service life 30000-50000 hours;

- multi-pair mesh does not exceed 70%;

-"hard" (as in traditional involute and worm gears) engages requires mounting clearances. Hence the possible backlash, providing minimum clearances leads to a significant cost of production;

- massive block of satellites has a considerable moment of inertia, which leads to an overload of the high-speed bearing block satellites and reduces the service life of the gearbox;

- the design complexity, the existence of a block of satellites, solid tubular bobbin, which is inelastic, the availability of high-speed bearing block satellites.

These drawbacks are eliminated in the proposed invention is a multifunctional complex drives PCR. Long-term studies show that the design of the drive gear with the shortcomings of the prototype is impossible with ordinary mechanical Association of motor (electric motor) and a gear.

You need a radical change of approach to the unification of units of electric motors and gear based on the merge and improve their functions. That is, the motor should be part of the gearbox with the performance of its functions, and the gear should be part of the motor with his usual work.

The required technical result and the purpose of the invention is to combine together in one design of electromagnetic and mechanical functions of the motor and gearbox to improve the techno-Economics the economic parameters of the proposed multifunctional complex FEM PCR actuators on the basis of planetary cycloidal reducer - The PCR.

The proposed multifunctional complex with electric gear PCR is a new and promising direction in reductionstrategy because he engages cycloidal krugovenko, multipair, progtesterone spring with a comprehensive surround a Central, symmetric, semienclosed nature of the work in all pairs of its engagement, and with the simultaneous use of conductive features an electric motor, a stator and a rotor. The latter is achieved by the fact that his engagement, support and planting elements are made symmetrically on a sliding landing construction, and operation of the gearbox Assembly with a set of actuators with PCR is carried out with lubrication in optimal conditions with minimal magnetic losses, friction and heat[7, 8, 9, 11, 12].

Thus, FEM PCR corrected working Assembly clearances and clearances. Along with high efficiency (about 95%), this complex drives has increased the contact strength, reliability and durability, reduced intensity and dimensions 2-3 times, the process does not generate noise [2-6, 7-12].

Gapless gapless nature of the engagement allows the use of FEM PCR in high-precision systems, and the combination of motor and PCR in a single multifunctional complex drives Zn is significantly expanding the scope of its implementation. The total production and manufacturing costs decrease by about 3-5 times.

Similar complexes of actuators and gearboxes can be used in actuators of robots and manipulators, precision ground, space and the underwater navigation, missile technology, engineering tools, electric vehicles, transportation, hoisting machines, electric windlasses, for transmitting rotation in a tight space, in the oil and gas and other industries, in medicine and various scientific studies.

Composition and appointment of the multifunctional complex of the actuator on the basis of the PCR is shown in Fig.(2-5) and includes the main motor, main drive which is connected with junction engines (e. drives) using providermessage krugovogo spring gearing in the form of an open Central rotor 2 or in the form of a closed toroidal helical springs 3, 5. The listed units and units of the complex are placed on a common ground, the body of the main objects, helicopters, missiles, etc. Novelty and usefulness of the proposed complex FEM PCR lies in its universality, first, it enables you to measure the capacity of individual motors (ED) and transfer them to the total maximum settings on the main drive, main Sylow the first body (5) missiles and its elements (roofs and the like), powerful witness complexes observatories, locators, stations in their observation of defense enemy objects, space, UFOs, meteors, flying towards the Earth, in the wind industry. In this case, smarter and more efficient summation of the power parameters of the individual motors (ED) on the main drive of the above units continuous and discrete control than creating individual instances of heavy-duty engines, ED, the disadvantages of which is added to the insecurity and emergency failure of the conditions necessary for them to operate in harsh environments and overloads, the impossibility of duplicating them. The novelty and usefulness of the proposed complex lies in the universality of the distribution and moments of power from the main drive (motor ED) on the distribution engines (ED) 5, for example, from the main engine engines additional screws and components of the helicopter, the flight control and maneuvering rockets on numerous controls and regulation of space stations, submarines, aircraft, robots and cybernetic devices, units, machine tools, transport, oil and gas industry, etc. is important Here is not only high efficiency and power characteristics, but significant reliability and trouble-free FEM PCR in contrast to typical emergency the STI and the unreliability of many of the existing transmission electric drives and their compounds. As a result, this complex FEM PCR with significant manufacturability, efficiency (≥95%) can be recommended for many trouble-free systems of automatic control and regulation of the most important and powerful units, missiles, space, exploration of the depths of the earth, the ocean, the newest weapon: the accident in this case was excluded and do not require redundancy. Combining primary auxiliary engines (motors, ED) and PCR in a single complex FEM PCR prospectively increases energy, reduces the weight, size, cost of production and operation (~ in order). Greatly expands the range of transmitted working moments and capacity, increase reliability and service life performance of up to 25 years with noiseless operation and without traffic congestion.

Research and testing of our inventions (patent No. 2312260 from 10.12.2007, and others) showed manufacturability and performance to create the basis of a multifunctional complex EP PCR with significant summarizing the properties of moments and capacity at the sum of their distribution engine (ED), drives and transfer the total energy on the main drive engine (DG). Distributive character of the complex energy transfer parameters with the main drive motor (EM) to spare gateline distribution drives, units, motors (ED) provides reliable, optimal performance. In figure 5 the complex FEM PCR is the Central essence of the invention and allows almost structurally simple with minimal cost and effectively implement the main task of the power system - summation and distribution of energy in various systems, devices and robots for defense and industrial applications. It is also important that the implementation of FEM PCR possible in limited sizes and quantities, place them in helicopters, submarines, space, aviation, etc. the implementation of the FEM PCR is strengthened by the fact that its composition may consist of electric motors, and motors and drives of various structures, including internal combustion engines. So in each plot, the unit (element) complex FEM PCR amplification and reduction of weight, dimensions (figs 2, 3, 5, 6) is determined by the gear ratio i based onwhere Zb- the number of turns of the toroidal closed krumovitsa and open springs - rotor, Zk- the number of visits of the engagement grooves of the magnetic circuit of the stator and the spring rotor. For the main closed version of the FEM PCR in figure 2, Zk=1.

In the present invention FEM PCR also offers multiple variant complex 6, for which the CSO the number of visits in engagement according to our research of optimal and adopted Z k=3. This variant of the complex, along with the expansion of the range of gear ratios, has other additional advantages and destination. So, in the future, the transition from a single gear to the multiple engagement (e.g., Zk=3) will be changed during operation gear ratio and, accordingly, to pass work time and power in the desired range. The essence transactnow gearing (6) that wire three respective springs multiple gearing rolled on a special mandrel and after appropriate thermal and technological treatments of all three springs (Zk=3) as one set, are fixed for further use in unilateral Central non-magnetic metal or plastic casing mandrel, i.e. team 3-sahadeva spring like industrial metal functioning as a single spring (main version). Transahara mate gear (stator, gear 6, 4) parameter (Zk=3) determines and gear ratios. Technically valuable and it is important that the average spring transactnow spring rotor is made of copper (the two extreme magnetic steel), because in this case, copper spring creates the best optimum conditions entries batch which I electromagnetic fields conductive stator and rotor with copper windings. In regular ED, as a rule, the stator and the rotor have their conductive copper winding.

In any case, in the second embodiment transahara spring appears to be a single spring rotor design, all three of its spring, regardless of the material of the springs are sharing a single transmission of mechanical motion, General kinematics, from the stator to the spring rotor or from the spring of the rotor on the stator, gear camshafts 6, 4. So with monotonous similar character movement single and transactnow rotor latter has differences in expansion of the range of the transmission power parameters, torque and power, in accordance with the law of the gear ratio, which for transactnow is determined by dependencewhere Zk=3. At the same time when using transactnow rotor increases reliability, resource exploitation, with significant congestion transactnow gearing, in the best conditions of the electromagnetic interaction of the electromagnetic fields of the stator and rotor when it trehzahodnoy rotor copper secondary winding. Thus, the Central conductive rotor with copper winding becomes a full electromagnetic rotor, i.e. the stator and the rotor transactnow complex work and operated Optima is enom mode of interaction of two electromagnetic fields of the stator and rotor. Design transactnow spring rotor 6 is simple and like industrial metal mounted and securely fastened on the inside with plastic or metal non-magnetic shell.

Important differences and advantages of closed-loop and open-loop versions of complex FEM PCR. Closed modification of the complex are essential in the distribution of energy from the main drive of the main motor on numerous additional screws as helicopters, machines and mechanisms in limited sizes and quantities of many military, research and special vehicles aviation, space, submarines, robots, manipulators and cybernetic units. Open the modification of the complex simpler closed and allows you to enable a greater number of auxiliary drives, motors for concentrations of boosted energy parameters on one or more of the major drives serving complex, bulky, power stations and units, the Observatory, the locators for the control and supervision of flight of space vehicles, civilian and military objects, planets, meteorites, etc. In these conditions, the overall dimensions and the volume of placement of the open-ended design of the complex is not significant, as are the principal sum of power functions. T is thus, the use and operation of open and closed versions of the complex are determined by the total conditions of the specific tasks of these complexes with given dimensions and volumes for their placement, aggressive environment, work space, on the ocean floor and in the depths of the earth, etc.

The closed design of the actuator prior to construction of the present invention, with odnazhdy Central conductive spring rotor designed, manufactured and tested by us [2-6, 10]. The present invention is a complex FEM PCR significantly extends previous introduction to the complex of a significant number of components and connections between them. So in the complex was put gear (from three to five or more) on the distribution shaft, on which is fixed distribution motors, drives, actuators. All these gears, camshafts with the motors (actuators) are merged into a single design of the proposed complex (figure 5, 6), which engages in the operation and use as a common unit, the joint main motor, the actuator, the conductive Central provideproperty closed rugbytown spring rotor, which is in operation continuously connected, communicates and transmits rotation to the gear camshafts with distribute is ranked on the engine (figure 5). All these additional parts, assemblies, gears, camshafts with motors, drives listed in the options as closed and open complexes combined with the main drive gears and camshafts with ED, actuators, using a single, transactnow conductive spring rotor (2, 3, 5, 6).

With all the differences in the structures odnofotonnogo closed and open complexes EP PCR with transactoin (mnogoshagovyi) Central spring rotor execution of technically appropriate and possible. So when open complex trehzahodnoy spring version of last rotor specially wrapped and secured firmly to the Central tubular mandrel (plastic or naminememories), this team uniform design open spring rotor interacts in General a single unit at all stages of its operation and maintenance. The use of open complex wiring with transactoin, as with odnazhdy rotor, greatly increased due to the significant expansion of the range of transmitted energy parameters, because you can increase the design of complex number of main drives, ED and additional ED distribution, drives, components, assemblies taking into account the possibility of the wow expansion work dimensions and volumes to host open variants of the proposed complex. When the closed design of the complex, trehzahodnoy spring rotor manufactured and presented to the toroidal transformam rotor, assembled and firmly fixed to the toroidal special tubular mandrel (the same as for open option). This design of the closed complex with transactoin rotor harder, but her indisputable superiority in the use of this complex in limited dimensions and volume for its placement on the basic objects of missiles, helicopters, aviation, space, submarines, etc.

These drawbacks are eliminated in the present invention FEM PCR containing body parts (enclosure with cover, electric motors (main and distribution), fixed and connected through the bearings and gearbox, passing through the rotation from the motor to the output shaft that is different from the prototype by applying it to the elastic conductive multipair krugovogo spring engagement of the rotor 2, 3, 5, 6 made of conductive springs, geared and interacting with cycloidal teeth of the stator ED and gears camshafts (figure 3). The prototype (figure 1) used steel hard odnomernoe engages outdated evolvent the CSOs profile [11] with the presence of backlash and clearances in engagement, with the shock nature of his work, resulting in high friction, reduction of resource exploitation and destruction of the prototype, and noise during operation lead to his discovery, which is unacceptable for military submarines, etc.

Multipair spring helical gearing of the invention of figure 2, 3, 5, 6 differs larger transmitted moments, capacity, reliability, durability, long life operation with overload (≥25 years) and efficiency ≥95% at optimum samanalawewa the nature of work in extreme conditions and under the influence of the nuclear electromagnetic pulse.

The above advantages of the FEM PCR successfully and economical use of the invention in transport with application to him flywheel engine design Nwhole [12].

The invention FEM PCR according to claim 1 differs from the prototype (figure 1) efficiency, adaptability and simplicity of the design, so necessary for the introduction and mass production, because the production of FEM PCR used in industrial metallurgy and the production of the manufacture of special steel springs very wide range of defense and civil engineering with significant experience and improve their production, including hemelektronik by lapping them interacting surfaces, allowing to ensure the ecity their implementation with almost no loss of efficiency> 95%.

Design FEM PCR Nova and perfect and the fact that its elastic spring rotor with a cycloidal convex profile (tabs) is in constant engagement with a concave profile (cavities) of the stator ED and gears camshafts, mirrored krugovogo spring rotor profile. These activities are reflected in the works [2-6, 10] and the cost of its production is minimal and virtually waste-free manufacturing and optimally, tech.

Fabrication of conductive spring rotor, stator and connecting gears reduced cost 5 times with the expansion of its implementation in the defence, mashinostoitelnogo, transport and other equipment. This increases the durability, reliability, service life ≥25 years, passed reinforced moments and powers, at play-free, noiseless nature of its operation. It is also important that the production of FEM PCR is economical Assembly of the character of the finished parts: steel, twisted springs, rollers, noise reduction, gears with a small modification. The production of a prototype of figure 1 expensive metal, the transition of his chips, sophisticated production technology (subtableau, gear milling, heat treatment and so on). Hence promising implementation of FEM PCR missile, space and other equipment.

The invention FEM PCR differs elastic proii the major rugbytown gearing in the form of open or closed toroidal spring rotor, welded in construction in the form of a torus, is characterized by a Central, optimal self-tuning cycloidal gearing, round profile. It is best in mnogodelnosti and that krumovitsa convex profile of the spring rotor 2, 3, 5, 6 continuously mates with a concave profile (teeth) of the stator ED, gears[7, 8, 9, 11]. The prototype of figure 1 with outdated involute onopordum hard engages the convex profile of the gear teeth engaged with the convex profile of the teeth of the wheels [11]. Hence the prototype clearances and gaps in engagement, considerable friction, impact the nature of his work, resulting in the destruction. In the end, the prototype low life with congestion, unreliability and low efficiency (≤92%). Manufacturing Economics FEM PCR with his multipair rugbytown spring rotor, rollers, noise reduction, gears is considerably higher than the economy of the prototype with outdated involute gearing. So when making its gears and wheels 1/3 metal blanks goes into the chips, losses. Production FEM PCR is the most effective, economical, non-waste developed by industry [2-6, 10], and its operation is gapless character with precision testing command signals without loss of information and allows operation over 25 years. Resource exploitation prototype in laboratory conditions does not exceed 5 years.

p> The complex drives FEM PCR (figure 2, 3, 5, 6) has a more perfect new manufacturing technology, balanced, resilient conductive spring rotor with rugbytown engagement with its Central location and semipreparative optimal nature of the work to surround the forces of the electromagnetic interaction of the electromagnetic fields of the stator and the conductive spring rotor on a sliding fit, if necessary, lubricated, and magnetic interaction volume krugovertb profiles engage the stator and the spring rotor is made by closed magnetic circuit without the air gap, i.e. the optimal maximum use of electromagnetic energy of their interaction[7, 8, 9, 11]. The prototype with its one-sided hard odnomernoi impact zone of engagement of the above properties is not. The latter leads to significant energy losses in the drive of the prototype, with a further sum of friction losses in involute pairs gearing, heat loss and the need for additional teploograzhdenie. The complex drives FEM PCR suggested a new kind of satellite, the role of which performs a conductive rotor rotating on a rotating electromagnetic field of the stator and rotating together with him (rotating e is ectromagnetic field), in figure 2, 3, 5, 6.

By analogy with planetary gear role was taken clowning in the invention performs a rotating electromagnetic field of the stator ED.

The pair of stator (or its liner, ball gear, rotor in their joint gear mesh (2, 6) carefully edited so that the engagement was free, sliding fit, without jamming of the teeth of the rotor in the hollows of the stator. The position of the rotor, it engages in all modes of Assembly and operation, must be one-sided with the direct touch of the teeth of the rotor cavities of the stator at a constant value of the eccentricity e between the axes of the stator and rotor [10]. This is a necessary condition of normal operation of complex FEM PCR.

The complex drives FEM PCR (1) differs from the prototype more perfect design run gears camshafts in relation to the hard structures of the teeth block of satellites with limited odnomernoi area of engagement of the prototype of figure 1. In the present invention, the gears are made by the original technology with multi-pair rugbytown concave profile of the cycloidal gear type and are in constant engagement with rugbytown convex profile of the spring rotor of the complex.

In the operation of the complex rotation of the spring R is the Torah through the gears camshafts with ED is more smooth, play-free, noiseless character, without loss of transmitted information (figure 4).

The overall design of the actuator, rotor, gear with camshafts and ED fixed on a consolidated basis for complex actuators, i.e. on the grounds of the main aggregates: submarines, helicopters, rockets, robots, etc.

Complex FEM PCR differs from the prototype in figure 1 by the formation of the eccentricity e between the axes of the stator and of the rotor 2, 6 physical electromagnetic interaction between the stator and the magnetic conductive rotor. Rotating electromagnetic field of the stator along the axis of the stator acts on the conductive rotor, which unilaterally and is drawn to the stator along the axis of the rotor. Between these axes occurs and is constantly kept the eccentricity e. The eccentricity e of the invention is negligible (of the order of units of mm) and is compensated by the total mass of the rotor, gears camshafts and the load. The prototype of the eccentricity e is formed adopted by the dimensions of the mating parts and components, resulting in an imbalance of the actuator and the need for its balancing and friction losses in sliding joints and the current prototype is significantly complicate its operation and application.

Explain that a rotating electromagnetic field of the stator ED in cooperation with the conductive rotor izobreteny is strictly captures and retains full entry krugosvetnogo profile (ledges, of teeth) of the rotor krugovorote (depression) of the stator. Thus is formed and stored eccentricity e of the invention. Thus the eccentricity e of the invention is formed of one node pair (stator and rotor), and the prototype of the eccentricity is determined by many junctions between its units and noise reduction, resulting in a significant loss of energy.

As a result, the resource exploitation of the invention achieves ≥25 years with total efficiency ≥95%, and the prototype of the resource does not exceed 5 years at a lower efficiency.

The complex drives FEM PCR at 3, 5 differs from the prototype by applying it to a new original gearbox with new and useful properties of the distribution and stacking energy parameters, moments and powers, and transfer them to the required directions. So when the distribution of 3, 5 electric power from the main motor drive 1 via the gear 3, the camshaft 4 is transmitted to many additional actuators, drives the camshafts. This novelty, usefulness and advantages of FEM PCR structurally simple and almost without loss to transmit power from the main motor, drive at various drives of robots, machines, mechanisms, screws, helicopters, missiles, space and transport medium spans the century Very important, new, useful and summation of energy, when the total energy is the energy parameters of the moments and of the capacity coming from all individual motors, actuators (figure 5), the energy of which is greatly enhanced and concentrated on the main drive, the electric drive 1 5 providing and operation of a powerful, bulky, complex and expensive units: observatories, locators ground-based observations of the flight of missiles, space vehicles of the enemy, UFOs, meteors, and other equipment.

Complex FEM PCR is presented in 2 versions: open at 2, 6 and closed on 3, 5, which is associated with a specific work and the operation of these modifications: the volume and dimensions on their location, energy parameters of the transmitted torque and power, the possibility of a simple and rapid increase in the complex of 2 or more main drives, many additional drives in various combinations. The prototype of figure 1 above characteristics does not possess.

Complex FEM PCR on 6 differs from the prototype, with odnomernoi rigid scheme for transmitting rotation, the presence of several different schemes and structures operating in different modes of distribution and summation of energy different from other characteristics. For primary energy transmission, distribution and the Oia and the summation adopted complex with odnosektornoi design engagement stator ED and magneto-conductive rotor, for which gear ratio i is determined according towhere Zb- number of turns of the spring rotor, Zk- number of visits in their engaged position, and for odnofotonnogo gearing Zk=1.

Hence gear ratio i is determined by the number of turns odnofotonnogo spring rotor and can be ≥100, etc. is Accepted and the second, new, multiple, optimal trehzahodnoy option, with Zk=3, which expanded the range of ratiosin the future allowing its regulation during operation. Trehzahodnoy variant of the complex figure 6 provides a new, useful and advantageous features. So the design of the rotor (6) is made of 3 springs, two at his springs are made conductive steel, and the middle (third) spring made of a copper conductive. When enabling 3-zawodowego complex supply optimal rotation of its rotor (Zk=3) is a more powerful interactive rotating electromagnetic fields of the stator ED and conductive rotor. With increasing power of the interaction of these fields increase energy characteristics only to the Plex FEM PCR in General. In the end, multifunctional complex drives - FEM PCR performed on perfect effective design with the fundamental distribution functions and summation of energy and its parameters. When the distribution of energy from the main motor (actuator) is distributed with high efficiency on numerous drives rockets, robots, submarines, etc. There is a simple, mechanically durable power complex, allowing overload when operating in aggressive environments. Nova and function of the summation of the complex energy and its parameters with the intensification and concentration of total energy parameters from all separate electric motors (actuators) on the main drive, power plant maintenance powerful observatories locators. Introduction summarizing complex is more efficient than the manufacture of single expensive heavy duty main power motors, actuators. It is also important that high-strength complex drives has considerable reserve of strength, reliability and in warfare. Studies have shown it to be mechanically reliable operation, performance, survivability, even when hit by bullets, shrapnel, nuclear electromagnetic pulse, etc.

Existing analogues and prototypes with their numerous and complex wiring in military hostilities owl is totally not protected from damaging their bullets, shards of ignition and ignition wiring and unacceptable because of their unsuitability for use in wartime.

FIELD: electricity.

SUBSTANCE: present invention relates to electrical engineering and electromechanics, particularly to electric machines, and pertains to distinct features of design of a planetary electric motor - reducing gear with a lever for controlling the commutator. To increase excentricity of rotation of the commutator by several times compared to excentricity of the satellite - armature, the proposed planetary electric motor - reducing gear employs a lever for controlling the commutator. The proposed planetary electric motor - reducing gear has a planetary gear system in form of a friction pair or planetary reduction gear, the first step of which executes functions of the stator and satellite - armature of the electric motor. The commutator rotates synchronously with the satellite - armature. The stator and satellite - armature are fitted with solenoid coils, which shift the satellite - armature about the point of maximum entrance of teeth of the wheel and primary pinion of the planetary reduction gear into each other, or about the point of contact of the friction pair. The commutator, which can rotate excentrically about the housing, provides for phase shifting of the electromotive force of the electric motor and closes the solenoid coils of the stator and satellite - armature. The lever for controlling the commutator has different arms, the end of the shorter one of which engages the statellite - armature, and the end of the longer one enters the collector, providing for its rotation with excentricity, which exceeds excentricity of rotation of the satellite - armature. The commutator can be used with butt-end and cylindrical arrangement of contacts. The current input and output elements of the commutator do not rotate, they only oscillate.

EFFECT: improved operation of a planetary electric motor - armature, reduced spark formation of the brushes and electric arc from commutator contacts, as well as provision for wide regulation of frequency of rotation, torque and reversing the electric motor.

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering immediately dealing with design of gear motors and electric drives and is to find application in robot and manipulator high-precision drives, ground and space navigation, machine-tool industry, transportation sector, oil-and-gas industries etc. The proposed electric drive based on resilient engagement planetary cycloidal reduction gear contains an electric motor and a reduction gear rigidly mounted on the electric motor shaft and transmitting rotation to the output shaft through the reduction gear bearings. Under the first version of the invention implementation the electric drive reduction gear design envisages central position of the resilient elastic engagement between the elastic satellite and the central wheels which solution ensures their backlash-free, noiseless and generally optimal operation and utilisation. When the electric drive is controlled by a continuously-operated or a discrete electric motor the resilient circular screwed engagements of the elastic satellite and the spring-loaded rollers continuously remain in a central optimally self-adaptive engagement. Under the second invention implementation version the electric drive is designed as equipped with a planetary cycloidal reduction gear with the electric motor output shaft represented by a spring-loaded rotor connected to the output shaft of the reduction gear whose satellite continuously remains in a central slide-fit engagement with the central wheels magnetically conductive convex profile. Magnetic interaction of the resilient spring-loaded satellite with the central wheels springs is designed to proceed within a closed magnetic circuit without air gap. The electric drive is designed to equally allow of operation as continuously controlled by an electric motor and as discretely controlled via electric pulses received from the control unit or a digital computer. The proposed design of electric drive based on resilient engagement planetary cycloidal reduction gear enables significant improvement of the device performance characteristics.

EFFECT: provision for transformation of the electric motor rotor rotation into backlash-free and noiseless rotation of the output shaft ensuring considerable amplification of torque and capacity.
