The actuator on the basis of planetary cycloidal reducer with elastic mesh (EP PCR) refers to geared motors, actuators and can be used in precision actuators of robots and manipulators, in both terrestrial 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 opened the original transmission with the elastic engagement between the ground of the Earth and rubber wheels, tires, transport, known for more than hundred years. They are characterized by high reliability, resource and adaptability [9, 10] for operation in extreme conditions and overloads, and to self-organization on the formation of ground engagement, maintainability. They have a high prospect of longevity with tons of traffic and high speeds silent when x is the nature of the operation. There is a peculiar and original analogue and a prototype of the invention. Deficiencies and accidents of similar eliminated in the present invention EP PCR U. So shallow zone of engagement of the tire with the ground (~10°) expands mnogozahodnoy and more elastic zone of engagement of the EP PCR At up to 300° or more (2÷6).
The invention improves the reliability, lifetime, transmission efficiency (≥95%), and characteristics based on the calculation and implementation in the manufacturing of optimum conditions of design and operation, if necessary, and with lubrication, it is impossible for ground engagement. 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) .
Design EP PCR provides The best energy saving and reduction of electromagnetic losses in electric motors, it expanded the range of gear ratios (i≥10÷4000), and analog prototype it is limited. EP PCR-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 studies under extreme conditions of bottom OK the Ana and space.
The PCR drive-In is a 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 PCR drive-In can be connected and plugged in conventional continuous motor, including special, and also be interfaced with discrete control systems from discrete sensors or computers.
Technical equivalents of the invention is a motor-reducers  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 are roboy 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 6, the cover 13, the input (master) and the output (driven) shaft 1 and 7, the stationary Central (sun) wheel 11 with a number of rollers (coils) 10, a cycloidal satellites 3, 5 block of 4 satellites, fitted the frame on the input shaft 1 to the shaft bearings 14 and eccentric bearings located satellites 15, inside the main wheels 11, 12, cycloidal teeth which engage with teeth of the Central wheels; the fingers 9, is pressed into the flange of the output shaft (the rolling of the output wheel 12 and freely worn on their rollers 8, which are included in engagement with satellite 5 block of 4 satellites, videos (pins) 10 fixed Central wheel 11 and the rollers (pins) 8 output shaft 7 (the rolling Central wheel 12).
Block of 4 satellites prototype of figure 1 is in constant engagement with the Central wheels 11 and 12, rigidly fixed respectively in the housing 6 and output shaft 7. Block of 4 satellites is connected with the eccentric shaft 2 by the electric motor ED in the bearings 15 and through the bearings in the cover 13, the output shaft 7 of the rolling wheel 12 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 about the provisions of the minimum gap 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.
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 motor and gearbox, 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.
1. These drawbacks are eliminated in the present invention EP PCR, comprising a housing with a cover, motor, mounted through bearings on the shaft associated with the gear and passing through the rotation of the electric motor to the output shaft that is different from the prototype by applying it to the elastic conductive multi-pair elastic (spring) gearing, whose elastic satellite made of cut is with us cord (type tires - one variant), geared and interacts with the teeth of the Central wheels in the form of twisted welded in tor steel springs (or as ready-to-twisted steel rollers GSR). The analogs and prototypes used steel hard odnomernoe engages outdated involute profile (see the works of academician Law) with the presence of backlash and clearances in engagement with the shock nature of his work, resulting in high friction, wear, reduce resource use, to the destruction of the prototype, and noise during operation lead to discovery of it at work, which is unacceptable for military submarines, etc. multi-pair of elastic engagement invention is large transmitted force and moments, reliability, durability, higher overload capacity, long life (≥25 years) and efficiency≥95% at optimum self-adjusting nature of work in extreme conditions and under the influence of the nuclear electromagnetic pulse.
2. The invention of EP-PCR-according to claim 1, differing from the prototype cost effectiveness, manufacturability, production, simplicity of construction, necessary for mass production, manufacturing and research drive, as for the production of EP PCR We used ready-made tires with minor revision in their teeth cavities Design EP PCR-perfect and his elastic satellite is in constant engagement with twisted steel rollers GSR (springs), which are made of sharikopodshipnikovs plants. Production costs EP PCR-reduced ~ five times with the expansion of its implementation in the defence, aerospace, helicopter, machinery and other equipment. This increases the service life up to 25 years of reliability, durability, moments passed and effort, efficiency up to ≥95%, with the quiet nature of its operation. It is also important that the production of EP-PCR-Assembly is economical character of the finished parts: tires and ready, twisted steel rollers WOOFER. The production of a prototype requires a considerable expenditure of metal, means for complex production - subtableau, gear milling, heat treatment, etc. Hence the implementation of the invention EP PCR-promising for high-precision objects defence, missile, space and other equipment. Design dual springs and areas of engagement shown in Fig.7.
3. The invention of EP-PCR, different elastic, spring-toothing in the form of springs, welded into the overall design in the form of a torus, is characterized by an optimal, self-adjusting gearing cycloidal profile. Its optimality is that krumovitsa concave profile elastic satellites with prageeta with convex profile (teeth) of the Central wheels twisted rollers (another option). The prototype is outdated involute toothing ((1)), which has a convex profile of the gear teeth engaged with the convex profile of the teeth of wheels. Hence the prototype there are clearances and clearances engagement with considerable friction, impact the nature of its work, leading to the destruction of the entire drive. As a result, lower uncertainty, resource and work overload capacity and low efficiency, ≤92%. As a result, the efficiency of the production of elastic, spring-loaded engagement in the form of goreobsessed springs, twisted commercials I hate the significantly higher efficiency of production gear solid prototype with outdated involute gearing, and in the manufacture of 1/3 of metal workpieces goes in deadweight loss (in the form of chips). Technology for the production of elastic, elastic, krugovogo concave-convex EP PCR in the form of a toroidal springs, twisted steel rollers GSR is promising, because it is a waste-free manufacturing of springs, rollers mastered by the industry. Thus, in the invention of EP-PCR-concave profile elastic spring satellite edited by grinding, and the spring Central wheels convex profile remains convex, i.e. not being finalized. Operation of the invention EP PCR-is gapless, silent character, precision otrb the TKA command signals occurs without loss of information and service for over 25 years. Satellite 5 in figure 5 is made (wound) on a special mandrel when the difference in number of teeth of the left and right of it in one tooth.
4. The actuator according to claim 1 characterized in that it applied krumovitsa profile sealed bellows, which when interacting with rugbytown engagement of actuator PCR-ensures the transmission of forces and moments in a tight space.
5. The actuator according to claim 1, characterized in that the switching speed drive is provided by an electric switch six sectors electroosmotic 3 stationary Central gear reducer with teeth Zb (see figure 5), due to the transition of the drive EP PCR on discrete control pulse from the control unit or from the CVM with implementation of EP-PCR-both in continuous and discrete modes of operation.
6. Known automatic couplers of the 2 vehicles (2 tractors, 2 locomotives) to increase traction on steep climbs and descents, when braking. We proposed that the coupling of 2 motorized PCR with the implementation of a new drive of the invention with a very significant increase in the time and effort that is essential in engineering. This coupling of 2 analogues, prototypes absolutely unpromising, because in this case you are using an outdated involute carried the attack to the presence of backlash and clearances, impact nature of the work, with considerable friction, low life and destruction of engagement with its operation in extreme conditions. In the proposed coupling of 2 actuators with PCR, characterized by the use of optimal cycloidal multipair, provovogo concave-vypuklogo engagement with improved characteristics in friction, quiet, unstressed nature of the operation, the resource and efficiency. With significant economical and technological production ratio hitch 2 drives with PCR-increasing moments and effort increases by one to two orders of magnitude.
7. The drive EP PCR At 6 and claim 5, characterized advanced manufacturing technology, balanced, resilient conductive spring satellite with its Central location and semipreparative nature of the work to surround the forces of magnetic interaction between the satellite and the center of the wheels from the electrical winding on a sliding fit, and the magnetic interaction between the satellite and the center wheels are made in closed magnetic circuit without an air gap.
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-economic the parameters of the electric drive on the basis of the planetary cycloidal reducer with elastic mesh EP PCR-U.
The proposed actuator PCR-has significant differences. So figure 2 shows the planetary cycloidal reducer EP PCR in longitudinal and transverse sections, respectively, with the use of gearing in the form of fixed Zb and rolling Za Central wheels and United with them elastic satellite 8. Figure 3 schematically shows the design of PCR-show providermessage gearing on an elastic Foundation. This is essentially a new original decision elastic gear reducer drive. Figure 2 presents the elastic engagement Assembly double springs 17 and 18, dressed on the axis 14. Under these conditions, the reaction load is transmitted to the satellite 8 and to the Assembly of double springs 17, 18.
Under the force of a satellite 8 is compressed and stretched the springs 17, 18 volume deform and adapt to the current in the load, thus improving the load distribution between a large number of teeth of the toothing. In the construction according to figure 3 elastic mesh consists of an Assembly of springs 17, 18, dressed on the axis 14. The Assembly is spring pressed against an elastic base 19 to the axis 14 with the efforts in the direction from the periphery of the crown of the flange of the output shaft 11 to the center. Under these conditions, when the gear teeth of the satellite 8 affect the Assembly of the springs 17, 18 on the axes 14 and "for the order" locally deform the elastic base 19, thus the gear teeth of the output shaft 13 is best adapted to the transmission of large torques and power going through the power flow from input gear, and through the elastic engagement is transmitted to the gear output shaft 13, i.e. on the load.
In the end, a simple elastic toothed assorted springs and gears provides significant power effect on the gearbox output on moments and capacity.
Thus, the simplified design of the electric motor with gearbox and improved their performance. Simultaneous pairwise constant mesh gears with Zb Zf and with Za Zq is the difference in the number of teeth in one tooth provides a significant reduction ratio and the maximum kinematic effect the transfer.
The transmission takes place in optimal conditions: concave round teeth elastic satellites 8 interact with the convex profile of the Central spring of the wheels 2 and 11 (figure 2).
In the proposed variant of the actuator PCR-twisted spring rollers 2 and 11 and the elastic satellite 8, in fact, created a new elastic-sided precision progtesterone gearing without working clearances and backlash, and during operation there is no slippage.
The proposed drawings included in the description of the invention and forming part of, illustrate before occhialini embodiments of the invention, and together with the description serve to explain the principles of the invention.
Figure 1 shows a prototype of the actuator PCR-U.
Figure 2 shows the actuator on the basis of planetary cycloidal reducer with an elastic engagement - EP PCR-U.
Figure 3 shows the drive with the design of the elastic base 19 for transmitting power effort from the input shaft to the satellite 8 and through the oversized double springs on the axles 14. Effort is transmitted to the movable gear 11 of the output shaft 13 in an optimal, efficient manner without loss of information.
Figure 4 shows a variant of compact actuator with PCR-using industrial tires as elastic satellites 8, that the rotation of the eccentric input shaft 4 from ED transmits this rotation when running satellites for the springs 2 fixed wheels and springs of the rolling wheel 15 on the axis 14 to the output shaft 13 with a significant increase of the working time due to the high gear ratio of the gearbox.
Figure 5 shows a variant of the small-sized electric (M EP PCR), elastic spring 5 satellite which is due to the angle of the eccentric during rotation of the shaft 1 (with angular exserviceman - α) part numbers on the springs 4 and 7 stationary and movable Central gear wheels and with a significant increase in moments transmits the rotation to the output shaft 9.
Figure 6 presents research drive in the pairing of the satellite with the finished tyre and running from special motor .
Progtesterone engages PCR-provides feedback on the load and ensures the efficiency of the gearbox and drive in extreme conditions. For efficient production of electric PCR sufficient accurate production technology as the most economical dominated Assembly operations, i.e. there is no need to copy the Japanese and other PCR enough to count and manufacturing its own, the most perfect examples of actuators PCR, which can be realized on the basis of the domestic ball bearing production on the basis of the tire and automotive industry.
The reliability of the power elements and nodes PCR Has provided accounting and adaptability elastic design assemblies to the random nature of the power load, i.e. it DAMPS, absorbs shock, vibration, space, temperature, radiation, abrasion and other types of loads or their combination.
In this case, the transmission takes place in optimal conditions: bilateral concave circular depression-teeth elastic satellites interact with convex profile provideproperty teeth fixed and ACC is the author of the Central wheels (gears) of figure 2, 4, 5, 6, and best of all, without slipping, adapted to the transmission of large torques and power than is provided by the great power effect on the output of the drive on the moments and the capacity, reliability, resource, congestion and other operational parameters.
One of the differences of electric PCR from The prototype - in the absence of high-speed bearings, light and medium series of the block of satellites by increasing the reduction of the rotation and decrease the rotation speed of the satellite 8 on needle bearings 6 on 2, 3 and moving parts PCR-U.
Industry perfectly worked metallurgy and manufacturing (drawing, winding, strengthening, heat treatment, homopolyamide etc.) springs with a simultaneous strengthening of the source material. The strength of high-strength spring belt, wire [2, 7, 8] after patenting, drawing, sandblasting and heat treatment reaches σin=182-257 kg/mm2.
Progtesterone elastic engages the drive PCR implements The feedback load and ensures that the design in extreme conditions.
Precision, provideproperty, the elastic nature of the engagement gear PCR-opens a very broad prospects for the introduction of plastics, metal, composition is traditional materials and tires with metal cord. This is especially true since a large number of actuators and the transmission is operated in strictly planned time - day clock. This devices operating in space, with a variety of their orientation in space, navigation systems for the study of planets, satellites, corrosive environments, actuators disclosure antennas, solar panels, fence, ground, etc.
Under these conditions, the dimensions, the weight, the resources required, production costs are decisive. Combining effective principles of design of electric drives PCR with The manufacturer of the satellite 8 to 4, 6 in the form of tires on factory technology and basic details of chemically resistant composite materials is vital when working in space, aggressive and shock environments, the chemical industry, systems exposed to electromagnetic pulse and radiation.
However, this is hindered by the significant slowdown of experimental studies of the actuator with the CVM and the reduction of their production.
Multi-pair engages PCR-makes effective use of the design hypocycloidal (epicycloidal), shell, cordrazine, metalloprietinsae gears that are durable, especially when the shocks and shock loads, a significant decrease is the group of mass, cost-effective technology and use of materials, which is important for high torque gearboxes defence aviation and space technology.
We offer these drives and planetary cycloidal gearboxes manufactured and protected by patents [2, 3, 4. 5. 6, 10] and are the basis for their implementation in a special sound play-free and noiseless system of control and regulation of ground, space, aviation, gyroscopic, the underwater navigation for robotic and cybernetic devices and apparatuses. Moreover, they are compact, self-contained, compact and can work in confined areas. They can also be used in systems moving parts of industrial robots. High performance drives with PCR-you can use them also for turning, milling and grinding machines with program control, for radar stations and antennas, for observing Earth satellites, radio systems, aviation, transport (electric vehicles), in the chemical and oil industry, in the moving wind power stations serving geological and military units.
As our research shows, already planning for the implementation of the proposed effective electric PCR in production quite a bit is botanas us the exact technology of production, as the most effective and economical.
Significant efficiency of PCR drive-In is accomplished by implementing it on the basis of existing ball bearing, tire and motor-vehicle production, which is dominated by the build process, without the use of expensive jig boring, shaping and hobbing equipment. Total production and processing costs decline by about 5 times.
Cleaner production, energy efficiency, waste reduction and the economic efficiency of manufacture and operation allow the use of the laws of elastic mechanics, the results of the implementation of the proposed actuators PCR, effective promising direction in reductionstrategy.
Very new and original in design of small electric PCR is The use of a new programmable two-way compact providermessage gear with precision elastic spring satellite 5 on 5 and twisted toroidal springs and twisted rollers of the Central wheels [2÷6]. The design of this compact drive - M EP PCR-due to its compactness, portability, smaller size and weight, extremely valuable, given the limited size of the instrument compartments of submarines, Vert is Letov, aviation and space technology, with play-free, low noise precision operational mode, without slippage and loss of information, in extreme conditions.
Design M EP PCR-allows during operation to change the angular eccentricity - α, which allows you to adjust in a wide range of area elastic engagement of a satellite with a Central spring-loaded wheels and thereby to regulate the transfer of significant issues of capacity with minimal losses.
Simple design M EP PCR, high efficiency ensure its rapid implementation with high reliability, lifetime, efficiency, technology of production (homopolyamide gear spring gear).
Its final drive ratio EP PCR, M EP PCR-reaches significant values (i≥10÷1000), may be fractional. The prototype with low efficiency limit of ratios is limited [1, 2].
Gear ratio i of the actuator of figure 2 are determined by the dependency on module:
where Zf is the number of teeth 7 left side elastic satellites 8;
Za - No. of teeth 15 of the rolling Central wheel 11
Zb - number of teeth 1 stationary Central wheel 2;
Zq - number of teeth 9 right side elastic satellites 8.
The working conditions of M EP PCR in frame link guides the flight control object, operating in the search mode and the precise placement and coordinate learning objectives, both in figure 5 is operable in both modes. Based on the conditions of the search mode, the compact drive is enabled in the control of normal motor ED 11 to 5. The exact positioning and target coordinates to the drive goes on discrete precision the nature of governance, and its six sectors the elektroobmotka 3 to 5 (3-x phase diagram) are control current pulses from the digital control unit or from the CVM.
In this mode, discrete rotating electromagnetic field winding 3 and the magnetic spring-elastic engagement of the stationary Central gear 4 and the satellite 5 is converted into a discrete forging the left side of the magnetic spring of satellite 5 to the gear 4. Simultaneously, these rotation (spinning) of the satellite 5 (right spring side) is converted into a discrete rotation conductive spring gear 7, i.e. the rotation of the output shaft 9. The rotation of the output shaft 9 M EP PCR-occurs with a significant power gain due to its high gear ratio
iM EP PCR-= iLCAST· iPROACTI,(iM EP PCR-≥100).
So, in the left part (iLCAST) spring elastically what about the gearing, the number of concave depressions left side of the satellite 5 (Zf) per unit is greater than the number of convex profiles (teeth) spring wheel 4 (Zb), and the number of teeth in the right side of the satellite (Zq) per unit is greater than the number of convex teeth of the movable gear (Za). Under these conditions, the total gear ratio of this drive for 5 is:
where Z4=Zb=19, Z7=Za=20, ZLSAT=Zf=20, ZPRSET=Zq=21.
This double-sided concave engagement balanced satellite figure 5 view And with the convex profile of the Central gears of the drive is made on a sliding fit of the Central, self-determined, self-organizing [7, C; 8, C; 9] optimal surround forces [7, 8, 9]. Since the interaction of all cores of the satellite and the center of the wheels in their spring engagement occurs constantly and without air gaps, the magnetic interaction is carried out in a closed magnetic circuit [8, s].
A feature of all structures of the actuator PCR-is their ability guaranteed to keep exhaust command signals (pulses) and between teams not to consume electricity.
Energy-saving drive with high efficiency (≥95%) is valuable and irreplaceable in aggregates with Autonomous power sources: aircraft, underwater and space navigation tools, robots and programs in a sealed environment through the hermetic bellows.
On the basis of accom is imago drive is provided with high reliability, durability, less friction losses, the best vibro-acoustic and physical characteristics overload capacity, redundancy of components, assemblies and components that existing drives impossible. Actuators PCR-able to account for the random nature of the active power load, to adapt, i.e. to damp shock, vibration, cosmic radiation, electromagnetic, abrasive, underwater load or their combination[7, 8, 9].
A large overlap ratio on the gears of the gear drive provides high kinematic accuracy, smooth, without slipping, play-free, noiseless operation of the actuator, which is valuable for the defense and scientific purposes. Trouble-free operation is ensured by an elastic (rubber with metal cord), spring compensators in the form of a twisted double springs, provideproperty twisted rollers and satellites springs, which by mnogodelnosti in the gearing increase the transmitted electric moments and efforts during overloads.
Homopolyamide engage the spring clips satellites reduces friction, increases the corrosion resistance of the mesh [4, 5, 7, 8] and the efficiency of the drive. Based on the experience of a number of research institutes of the Russian Federation as a material for a spring engagement can recommend steel ø the 15, SH, 12HN3A and other steel satellites, as well as rubber tires existing vehicles.
The design of the actuator provides for the operation of the switching speed at the gearbox output due to a change in work gear 2 for 2 when you switch it from still mode to partially movable. The switching speeds possible both electrical and mechanical.
New and original in the drive presents double teams the springs 17 and 18 of figure 2, in which the outer spring 17 with the tension screw located on the inside of the spring 18; the entire Assembly of double springs is located on the axis 14 and provides a play-free, three-dimensional and longitudinal deformation of the General Assembly of the springs during operation, thus increasing the load capacity and service life of the drive.
Progtesterone engagement of the actuator and an elastic satellite implements feedback load and ensures its performance in extreme conditions and overloads, when using an elastic spring elastic wheels and satellites in the form of the finished twisted rollers and tires on 4, 5, 6.
A pair of actuator PCR with power electronic based control computers will greatly improve the efficiency and performance of El is of tropicoco all the above-mentioned control systems and for the study of UFO and other spacecraft.
It is the presence of clearances and backlash in the gearing of the most common gears and prototypes is the cause of the shock nature of their work, leading to mechanical damage and destruction of teeth and drive in General.
Design EP PCR Have also characterized the ecological purity of its production and operation, energy conservation, waste reduction, economy of manufacture.
Advantages of PCR drive-In is recommended for power drive (self-propelled chassis, a motor-wheel) on the study of the moon, Mars and other planets of the cosmos. Thus, in the experimental model of the truck in each of the 4 wheels mounted in a DC drive type PCR, thus achieving the autonomy of each wheel and to protect the truck from exposure to space.
For studies of the actuator PCR-M PCR-toroidal and dual springs, spring satellites and twisted barrel rollers, it is advisable to produce a wound, and the technologies of precision pressing, casting, powder metallurgy of various materials and their compositions. For hull units are recommended alloy D16T, VT and others, as well as plastic-type AG-4C, etc.
The conclusions. The invention of EP-PCR, M EP PCR We have provideproperty, multipair, precision, play-free and noiseless nature of the engagement, provide the named transfer in a wide range of significant moments and capacity with high reliability, a great resource overload and with an efficiency of ≥95%.
These actuators valuable use of proven production technologies in the manufacture and use of ready-made springs, twisted rollers, tires in its flexible, efficient and optimal types of links.
This drive should be used in highly accurate, play-free and noiseless transmission, navigation system, ground (electric vehicles), aircraft and underwater vehicles, systems of regulation and control devices Cybernetics and robotics, the oil and gas industry, machine building and other fields of science and technology.
