Figure 1 shows the proposed plan is ary motor-reducer gearbox, placed inside the satellite, anchors, and levers gear shift rods located inside the output shaft. Satellite-anchor includes a shaped discs, made of elastic material (e.g. rubber with cord). Shaped disks with peripheral and internal parts have a seal, which pumped liquid medium. In shaped disks inserted cores of permanent magnets or mounted them wires. Figure 2 - the same, the section a-A. figure 3 - the same, the section B-B.

Figure 4 shows the planetary motor-reducer with detachable gearbox housing and disks for placing inflatable tires (wheels), posted on the gearbox housing and the outer surface of the satellite-anchor.

Figure 5 shows the planetary motor-reducer with variable eccentricity of rotation of the satellite-anchors, of which there is no transmission, and the frequency of rotation of the output shaft depends on the change of the eccentricity e, which is changed from the pressure of the air or fluid in the tires (wheels).

In building the CE 1 (1, 2 and 3) is the stator 2 with coils 3 coils. Satellite-anchor made of elastic shaped discs 4, which on the outer and inner diameter are thickening 5 and 6, the cavity of which is pumped compressed air (liquid medium). In the shaped disk 4 is inserted curved cores 7 permanent magnets or coils of the electromagnets. Thickening of 6 based on case 8 speed gearboxes. Switching synchronizers 9 and 10 of the transfer are made by the plungers 11 and 12, associated with the handle 13 of the gear. The plungers 11 and 12 are connected with the levers 13 of the hinge and are able to rotate relative to the last. Washing of the coils of the electromagnets of the stator is supplied from the collector 14, which is fastened to the bearing washers 15 and 16, and the slide on the ends of the caps 17 and 18 of the housing. Electricity to the manifold 14 is fed through the washer 19, the sliding ring 20, is rigidly fixed to the manifold 14. Ring 20 wires 21 are connected with rings 22, which are based on contacts attached to the spring plate 23. When applying an electric current through the contacts of the spring plate 23 located at the top of the reservoir 14 (see figure 3)via the coil of the stator (for example, "a", "b", "C", "d" positive charges, and "e", "W", "C", "and" negative (figure 2). Coil "a", "b", "C", "d" prithi is with satellite-anchor to itself, and coil "e", "W", "C", "and" - repel it. Satellite-anchor down compresses the thickening 5, and above - thickening 6.

The output shaft 24 and the housing 8 of the gearbox is shifted to the eccentricity e1that provides the gear and the gear of the transmission. A distinctive feature of such placement of the gearbox is that it is placed inside the satellite, the armature of the motor, and the shifting is effected by rods 11 and 12 are placed in the output shaft 24.

Figure 4 wheels 25 mounted on the outer surface of the satellite, the anchor, and the collapsible housing 26 of the transmission disks 27. The disks 25 and 27 are wearing large and small tires (wheels) 28 and 29. Bus 28 and 29 are inflated with compressed air (liquid medium) and have nipples. Bus 28 obkatyvalisj on the holder 30 of the stator, and the bus 23 to the holder 31 satellite-like who I am.

Figure 5 satellite-anchor has several wheels or bus 32, screw by screw line (resembles a fire hose). Bus 32 is fixed by the plate 33 by screws to the housing 34 satellite-anchor. Compressed air (fluid) into the tire 32 is supplied through the nipple 35, which holds the pressure in the constant. The output shaft 36 has a disk 37 with tires 38, in which compressed air is supplied through openings 39 and 40. At the end of the shaft 36 has a swivel 41 with the inlet 42 and the exhaust valve 43 device and the device 44 for reading the pressure in the tires. (On the output shaft can be installed not only wheels with tyres, but one bus, screw by screw line). Bus 38 rolls on the holder 45 satellite-anchor. When the pressure of compressed air in the tires 38 case satellite-anchor is lifted up (see figure 5), and the eccentricity e is reduced. When the pressure decrease on the contrary. If we change the value of the eccentricity "e" changes the rotational speed of the output shaft 36.

Consider the example

The inner diameter of the casing 30, which rolls bus 32, take D=60 mm and an inner diameter of the casing 45, which rolls bus 38, d=20 mm, the eccentricity e=1 mm, the rotational speed of the magnetic field corresponding to the frequency of rotation of the center for satellite-anchors with a radius equal to the eccentricity e, for n=5000 rpm, the gear ratio u of a friction pair is prepelitsa by the formula

after conversion you will get

The frequency of rotation of the output shaft 36 will be

With increasing eccentricity to e=4 mm get

The frequency of rotation of the output shaft 36 will be

Thus, the proposed planetary motor-reducer can be used with carton transfer and without it. If through the valve device 43 to release the compressed air from the tire 38, the shaft 36 will stop spinning (will slip). When filling tires 38 compressed air shaft 38 will come into rotation, that is, this mechanism can be used as a box clutch.

The main and two others linear actuators consist of microprocessor control system and drive powers, subsystem of emergency shut - down of the above mentioned drives by the patient in the form of two buttons, frame, stock, stepping micro motor, microprocessor subsystem of registration of axial force of the drives with the help of sensors on stocks, intermediate planetary reducing gear unit of 2k-h type. Sun gear of the above said reducing gear is fixed on the spindle of the stepping micro motor, described below, self-holding screw-and-nut transmission with threaded rollers, on the input end of the male screw of which carrier of the reducing gear is fixed. Sliding nut is made integral with the stock. The frame of the main drive is fully-fixed in the immobile ring with the help of the free - attitude hinge with adjustable holders of its angular position against the immobile ring of the apparatus. The stock of the main drive is connected to the bridge by a two - axis hinge , whereat three rams are fully-fixed in corresponding guiding lines, and on the other side there are three fully-fixed threaded rods. Guiding lines are connected with the frame of the main drive by a two - axis hinge. Three threaded rods through the second bridge are attached by a one-axis hinge to the mobile ring of the apparatus.Frames of the two other drives are connected by two-axis hinge with the immobile ring of the apparatus. Stocks of the other drives through the threaded rod are connected by two - axis hinge with the mobile ring of the apparatus. Stocks in all three drives are fastened to prevent rotation against their frames. Nut-and-screw transmission with threaded rollers consists of a male screw, threaded rollers, sliding and stop nuts. Male screw is made with tooth ring, threaded sliding part and a stopping part having two - stage cylindrical surface. One stage of two-stage cylindrical surface has diameter not exceeding internal diameter of the threaded sliding part of the male screw, the other stage has diameter equal to the mean diameter of the threaded sliding part of the male screw. Threaded rollers have sliding part with threads, threaded stopping part, tooth ring on the ends and cylindrical surface, diameter of which is equal to that of the thread of the sliding part of the roller. The above said one stage is placed in front of the stopping threaded part of the threaded roller, and the other above said stage mates with the above mentioned cylindrical surface of the threaded roller. Thread of the stop part of i-roller is axially off-set against the thread on the sliding part by value Δ P1=P(z30-z3)(i-l)/np, where Pis a thread pitch, z30 and z3 correspondingly numbers of thread entries on the sliding and stop nuts, np is the number of rollers, i=l,2,...,np. Thread angle on the sliding parts of the rollers is equal in size and opposite in direction to the thread angle on the sliding part of the male screw. Thread angle on the stop nut is made equal in size and direction to the thread angle of the stop part of the roller. Stop nut has tooth ring. Tooth rings of the threaded rollers mate tooth rings of the male screw and the tooth ring of the stop nut. Sliding nut is fastened to prevent rotation.

EFFECT: ensures better quality and shorter duration of treatment, automatisation of treatment with possibility of out - patient treatment, recording values of micro - movements and corresponding values of axial efforts in the drives with given reliability, weight and size of the drives.
