The level of technology

From DE 10019512 A1 famous lifter motor, the housing which contains the Cup for placement of poles and closing its case. The latter is a gear housing with integrated housing for the electronics, and between the two parts of the body is in the form of individual parts brush holder that serves as both a seal between them. Bowl for placing poles consists of deep drawing flattened cylindrical tube, open end of which is formed a flange, which made the screw holes. In the flange of the housing is made blind threaded holes, into which threaded screws, resulting in both parts of the casing firmly connected to each other. In the flange of the bowl more planting holes than required for connection with the housing. So this Cup for placement of poles suitable for Glaswegian with different gearbox housings with different response of planting holes, however, the motor must always be installed in the axial direction in the housing and to fix it. For this reason, used outdoor motor unsuitable for use without the housing.

Disclosure of inventions

Proposed in the invention of the electric motor for actuating actuators in a vehicle includes a shaft anchors installed in the enclosure poles containing the shell and located at least on one end side of the bearing cover to accommodate the bearing shaft of the armature, and in the case of poles made of radial grooves, which, after complete Assembly of the enclosure poles are designed for entry radial mounting edges of the docking device of the gearbox in the case of the poles to secure the motor to the connecting device of the gearbox. Radial grooves made in the case of the poles by cold working of the material by the pressure due to the plastic deformation of a region of a wall when it is extruded by the punch and/or made in the form of an aperture in the housing wall of the poles, and the parts of the body poles located between the radial grooves in the circumferential direction, is left undeformed and thus form stops for fixing ribs acting in the circumferential direction.

Th is proposed in the invention of the gear drive unit includes a housing with at least one radial mounting rib and proposed in the invention of the electric motor, invest radial part of the housing so that at least one radial mounting rib includes at least one radial recess of the housing of poles of the motor.

Proposed in the invention, the motor and gear drive unit, characterized in the independent claims, have the advantage that due to the performance of radial grooves in the case of the poles, at a very low cost can be obtained very simply execute the connection of the motor with specific docking device of the gearbox (or transmission) of the customer. In this case the poles can always be made whole and be combined on a modular approach with different housings gears, connecting devices reducers, adapters or mounting flanges. Radial grooves may be made uniformly by means of a simple standard processes without requiring additional material. When the radial electric motor consists of two halves of the housing of the motor is securely fixed on it due to the fact that the current in the connecting device of the gearbox mounting ribs are radial grooves. On the other hand, bearing cap securely closes the case of the poles, so that the elect who dvigatel can find universal application even without combination with the gearbox housing. By executing the housing in the form of radially connected to each other with parts in the production process, you can use the machines for casting under pressure without ejectors, due to what can be greatly reduced costs to the instrument. Radial recess forms a compact, rigid in connection with the response part of the connecting device to connect the motor and all parts of the body and is therefore particularly well suited as a universal connecting means to the base of the engine. In addition, this system facilitates the dismantling of such a drive unit for repair or disposal.

For the radial recesses method of cold-forming with plug allows radial grooves economically and accurately, ensuring stabilization of the circuit area of the radial notches due to plastic deformation. During this process of cold working pressure not waste arises because the material is not cut, but only deformed. The result is improved stability of the form of radial grooves. This allows for a long time to exploit the connection of the motor with the gearbox housing in the loading conditions of high axial and radial effort, excluding the radial expansion of the grooves and the occurrence of backlash.

If the radial notch is made in the form of an aperture in the housing wall of the poles, this option is appropriate because in this case the material of the wall is cut out. This leads to reduction of weight of the motor. It is preferable to use a method of cutting down body material poles. The aperture may very economical and simple way carved in deep drawn Cup-shaped housing of the poles.

Proposed in the invention the design of the motor, on the one hand, ensures easy fixing from turning the motor in the housing, and at the same time located between the radial grooves undeformed areas of the enclosure poles attach to the enclosure poles resistance.

Private embodiments of the invention are disclosed in dependent clauses. Depending on the method of manufacturing an enclosure poles of the radial recess may be made at the end of the shell of the poles, and on the bearing cover. If, for example, bearing cap and shell are separate stamped parts, it may be expedient to cut radial grooves before closing the housing of the poles.

When manufacturing the casing of the poles by the method of deep drawing bearing cap can be done very easily in one piece with the front side of the shell. Due to this, one op the radio can be made closed with one hand Cup-shaped housing of the poles, and the hole for the speaker from the chassis of the shaft of the anchor is left free. Due to the performance of the bearing cap in one piece with the shell casing of the poles of the spherical bearing, and with it the shaft of the armature, can be located inside the Cup-shaped body very precisely in the center, resulting in reduced Assembly tolerances between the armature and the permanent magnet.

Due to the Assembly of the two bearing caps on the case of the poles of the motor can also be used without gear as a separate construction unit. The hole in the bearing cap creates an effective means of mates to the transmission. The shaft of the anchor protrudes through an opening of the enclosure poles to the drive device moving through the driven element. In another embodiment, for the removal efforts drive shaft of the device move can enter through the hole flush to the shaft of the anchor, which while not exiting the enclosure poles.

If the outer diameter in the area of the radial grooves is less than the outer diameter of the rest of the essentially cylindrical housing of the poles, and the diameter of the respective mounting edges of the docking device of the gearbox can be made smaller, making the outer diameter of the housing at the connection point does not exceed the diameter of the enclosure poles. Thus, it is possible to reduce the structural space of the housing in the zone of connection.

To prevent cranking motor in the housing or mounting flange, between the radial notch is left undeformed areas of the enclosure poles, so that they can form the supports for the mounting of the ribs in the circumferential direction. It does not require any additional manufacturing costs.

If radial notches made on the Cup-shaped enclosure poles opposite to each other so that they included the corresponding, opposite radial ribs, the motor is fixed in the connecting device of the gearbox equally firmly around the entire circumference.

For the return circuit path of the magnetic flux between the permanent magnets around the shell of the poles can be located in the second pipe poles, which completely covers its shell.

For accurate fixing position of the motor relative to the housing and a mounting flange on the bearing cover is made centering pin, which when entering the appropriate response in the recess radially centers the motor. The plot bearing cap, which is placed, for example, spherical bearing, the rolling bearing or Ude the supporting bearing spring, can be performed in the axial direction of the cylindrical, to keep it centered on the axis of the shaft of the anchor.

In another embodiment of the motor in addition to the radial grooves on the body of the poles made an additional axial grooves, in which to secure the motor can in the axial direction to enter the mounting edges of the docking device of the gearbox. The axial recess made in one piece with the radial grooves in the case of the poles, so that they form, for example, L-shaped recess for the bayonet catch (connections). In the case of a permanently mounted corps of customer gear this provides a simple axial mounting of the motor without opening the housing or the need for additional connecting means, such as screws or rivets.

All gear drive unit can be mounted radially due to the insertion of the electric motor of the radial part of the housing, and at least one mounting rib of the housing includes at least one radial recess of the enclosure poles. Simultaneously, due to the closure of the housing radially mounted cap or paleobiologii motor also for a long time fixed from movement relative to the housing.

By using the project for the housing, consisting of paleobiologic, all the details of the drive unit, including the motor can be mounted in one radial direction, resulting in the Assembly line can be considerably simpler construction.

Especially suitable option, in which the housing (base and cover) is made of at least two, preferably four, fastening ribs, as in this case, it is possible to prevent the motor stalling all four are perpendicular to each other in directions perpendicular to the shaft of the anchor.

If docked gearbox mounting ribs are made through a shaft holders in the form of protrusions bayonet connections, which are included in the appropriate axial and radial, in particular L-shaped, hollow housing of the poles, the motor can be very simply mounted on the finally assembled housing of the customer.

When the motor is exactly the same design should be fastened in different connecting devices reducer, adapter) has a mounting edge, made for example in the form of clamps or ribs bayonet connections, incoming in the radial grooves of the enclosure poles. Due to this universal base engine can be mounted in the housing and any mounting LAF is CE without structural changes of the motor. Thus, the adapter forms a practical element coupling the motor with any transfer mechanism (docking device of the gearbox).

Proposed in the invention is a method of connection of motor and coupling reducer is characterized by the fact that it comprises the following stages:

- enter the motor in the axial direction in the coupling gear, made in the form of the housing, and through the centering axle center in the return boarding socket coupling gear

- insert the mounting ribs coupling gear in the axial direction in the axial recess of the housing of the poles,

- the motor is connected with a connecting device of the gearbox by means of the bayonet catch, turning the motor in the circumferential direction relative to the coupling gear and the fixing ribs are radial notches in the case of the poles,

- fix the specified bayonet shutter locking device preventing separation of the motor in operation.

Proposed in the invention, the method of installation provides an extremely simple fastening of the standard engine on the gearbox of the customer, with very little needs in the design space. The engine may be the advent on the gear in the axial direction, and then rotated relative to the gearbox for reliable axial fixation.

The implementation of the invention

1 shows a gear drive unit 12, in which a separate motor 10 is connected with shown only partially docking device 15 of the gearbox, made in the form of the hull 16 of the gearbox. The motor 10 includes a housing 18 of the poles with the shell 20, the end faces 22, 24 which are made of the cover 26, 28 of the bearings. In them are placed the bearings 30, is made in this example in the form of bearings, in particular spherical bearings, through which the shaft 32 is installed anchor 33. On the shaft 32 is a package 34 of the armature core with electrical windings 36, which interact with the permanent magnets 38, located on the ring 20 of the enclosure poles. The shaft 32 is held at t McEvoy side 22 through the cover 26 of the bearing made through it in the axial direction of the hole 40. The shaft 32 with a driven element (not shown) is directed into the housing 16 to create through a gearbox (not shown), such as a worm gear, a torque that causes the moving parts of the car in motion. The housing 18 of the poles produced in this example by deep drawing sheet metal, and the shell 20 is made in one piece with the cover 26 of the bearing. Anchor 33 is first mounted in the housing 18 of the poles, then inserted the shaft 32 through the hole 40, and then is mounted separate cover 28 of the bearing. For certain applications advanced on the ring 20, is a second wall 21 of the enclosure poles in the form of closing the magnetic circuit of the ring. In the area of the bearing cap 26 has radial notches 42 to the right in figure 1 is made in the form of the die-cut opening 43 in the wall 49 of the enclosure poles. On the left in figure 1 radial recess 42 is embossed in the wall 49 by cold working pressure 41. During this process does not occur material waste. Radial grooves 42 are located in the area 57 of the housing 18 of the poles, the outer diameter 44 which in this case is the perfect way less than the outer diameter 48 of the shell 20. Section 45 of the bearing cap 26 is made in the form of a centering pin 50, which in the assembled condition, is included in the corresponding response in the recess 52 of the housing 16 of the gearbox. For fixing the electric motor is El 10 on the housing 16 of the gearbox mounting ribs 53 of the latter are in radial recesses 42 of the housing 18 poles. While fixing ribs 53 in the axial direction adjacent to the restriction of the radial grooves 42. Due to this, the motor 10 is firmly fixed to the housing 16 of the gear in the axial direction. The motor 10 is placed in the first paleobiology 62 of the housing 16 of the gearbox, for example, radially, causing the at least one mounting rib 53 includes at least one radial recess 42. After installation of the electric motor 10 in paleobiology 62 and mounting of the gearbox (not shown) the second paleobiology 63 is mounted radially to the shaft 32 of the anchor on poluobmoroke 62, and they are interconnected by connecting elements 66 included in the planting holes of the two parts 62, 63 of the housing. At least one additional fixing rib 53 paleobiology 63 includes at least one additional radial recess 42 of the housing 18 poles. While fixing ribs 53 or radial grooves 42 are not planting holes for the connectors between the motor 10 and the housing 16 of the gearbox, so that the motor 10 through one of the connection parts 62, 63 of the gear case or cover 62 with the base 63 of the housing is firmly connected with them.

In figure 2, the motor 10 includes a kind of bayonet catch as a mechanical connector for connection with the housing 16, the gear is or docking device 15 of the gearbox. For this to radial recess 42 adjacent an axial recess 47, which in the axial direction is inserted into the mounting rib 53, through the axial holder 55 is associated with the coupling device 15 of the gearbox. When mounting the motor 10 is first axially inserted into the corresponding connecting device 15, and then type bayonet shutter is rotated to a certain angle and, if necessary, also now. In the case of this type of connection housing 16 does not necessarily have to contain at least two radially joined paleobiology, and may be arbitrarily designed in the form of a bayonet connection. When this radial recess 42 is extruded directly into the shell 20 by pressure treatment, but may instead be made by cutting material, for example cuttings. Radial grooves 42 are made at the end of the housing 18 poles in one piece with the cover 26 of the bearing, but instead they can be performed also on the other end of which is closed by a separate lid 28 of the bearing Assembly of the motor 10. To do this, the shell 20 has a flexible mounting tabs 94, bend around the respective protrusions of the bearing cap 28. The shaft 32 passes, mostly over the length of the body 18 of the poles, so that entry efforts through the opening 40 in the cover modernica inner polyhedron 98, for example, the tetrahedron, the shaft 32 includes an introductory element 96, such as a flexible shaft. Such removal torque optionally available with one or both sides 22, 24 of the housing 18 poles. Between the bearings 30 and anchor 33 are thrust washer 100, preferably of plastic, which shaft 32 in the axial direction is supported by bearings 30. When this thrust washer 100 with detent lock is connected with the shaft 32 or located on the parts 102 anchors, such as seat sleeve 102 to the annular magnet 104.

Figure 3 shows a fragment of another motor 10, in which the radial grooves 42 is embossed in the housing wall 18 of the poles due to the plastic deformation by cold working 41 pressure. In addition, the material of the wall 49 of the housing poles only is extruded and cut, so that the wall 49 does not occur doorway. In one embodiment, the wall 49 is deformed so strongly that in the case of the poles there is an aperture (slit 51). Extruded section 59 of the wall is a flat surface, which when installed in a docking device 15 of the gear adjacent the mounting ribs 53. In another embodiment, section 59 of the wall can be clearly stamped into the housing 18 of the poles. In the variant shown in figure 3, the Cup-shaped housing 18 poles are not made of the axial recess 47, as electrodirt the eh 10 is designed for radial mounting in the housing 16 of the gear box with a lid or with two paleobiologii 62, 63.

Figure 4 shows another example in which the radial grooves 42 in the form of openings 43 in the wall 49 of the enclosure poles. They are made of, for example, by cutting from sheet metal subjected to deep drawing to form the housing 18 of the poles. In addition to the radial grooves 42 in the axial direction 109 is made of the axial recess 47, which form together with them opening 43, for example, in an L-shape. Axial grooves 47 are made in one variant (not shown) due to plastic deformation during pressure treatment, so that they, together with the radial grooves 42 extruded in the wall 49 of the housing. Axial grooves 47 are designed for axial Assembly 109 of the motor 10 in the expansion device 15 of the gearbox, in particular for the bayonet catch 17. While fixing ribs 53 are inserted in the axial direction in the axial grooves 47, and then the motor 10 is rotated in the circumferential direction, and the fixing ribs 53 are radial grooves 42 in the circumferential direction 108 and at least in the axial direction is fixed to the motor 10. Additionally can be executed by a locking device that prevents inadvertent reverse rotation of the motor 10 in its installed position in the circumferential direction 108.

Figure 5 shows another example of a gear drive unit 12, in the cat the rum motor 10 is not fixed directly to the housing 16 of the gearbox, and connected to the adapter 13. The latter also has retaining ribs 53 included in the radial grooves 42 of the housing 18 poles. The mounting ribs 53 are made, for example, in the form locking connection 11. When nadhani adapter 13 in the axial direction 109 on the housing 18 of the poles of the fixing ribs 53 slide on it until you are flush in the radial grooves 42 and firmly connect the adapter 13 with the body 18 of the poles. When the adapter 13 in the axial direction based hard surface 23 on the flange 25 of the housing of the poles, and on the other hand, the fixing rib 53 in a radial recess 42. The execution result of the radial grooves 42 are formed lugs 19 for fixing ribs 53, acting in the circumferential direction 108, so that the adapter 13 is also fixed from turning. The adapter 13 has on its outer periphery a radial projections 27, which he connects with the coupling device 15 of the gearbox, in particular, made by radial grooves (not shown). Using the adapter 13 can change the location of the radial grooves 42 in the housing 18 of the poles and mounting ribs 53 in the connecting device 15 of the gearbox.

Figure 6 shows the connecting device 15 of the gearbox, made in the form of a mounting flange 80, which is connected with gear drive unit 12 and the motor 10. Fastener f is ANEC 80 has a mounting bore 86 for connecting tools to fix on the body parts 15. The flange 80 is made in a single piece 81 received in a bending stamp, and has a radial mounting ribs 53, United with him axial holders 55. In the middle of the inside of the fixing ribs 53 are made hole 82, which includes a driven shaft 32, 96 and/or the centering pin 50 gear drive unit 12. The mounting flange 80 is first moved in the axial direction by the type of lug bayonet connections, and radial mounting of the ribs 53 of the mounting flange 80 is fixed in the axial recess 47 of the housing 18 poles. Then the mounting flange 80 is rotated in the circumferential direction 108 relative to the housing 18 of the poles, so that the radial mounting of the ribs 53 are radial grooves 42, made in the housing 18 of the poles in the form of openings 43 in the wall or due to plastic deformation during processing 41 pressure.

It should be noted that in relation depicted in the figures and explained in the description of examples of the numerous possible combinations of individual features among themselves. For example, it is possible to vary the specific implementation of radial grooves 42 and its location in the body 18 of the poles depending on the method of its manufacturing. Similarly, the fixing ribs 53 may have an arbitrary shape for the combination with the body 16 of the gearbox, and with the adapter 13. Thereby the armature 33, the housing 16 of the gearbox and the gearbox is there to match any known applications. A feature of the invention is that the same motor 10 acting as the base of the engine 10, is combined on a modular approach with different connecting devices 15 of the gearbox, such as the housing 16, the mounting flanges 80 or adapter 13, without requiring separate fastening means for connection with adjacent connecting device 15 of the gearbox. Preferably proposed in the invention of the electric motor 10 or gear drive unit 12 is used in devices for adjusting the position of the seats in vehicles, but can also be used for any other Executive drives.

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.

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.
