The invention relates to the Yan has received widespread transmission of rotation, containing interconnected slotted connection of the shafts connected by the coupling to the master and the slave nodes. Mounted on one of the shafts protective cover with sealing contact with the outer surface of the other shaft (see , for example, Anokhin Century. And. Domestic cars, Meters: machinery, 1968, S. 536-537).

From the specified source information known coupling comprising two coupling halves are rigidly interconnected by connecting elements.

A disadvantage of the known transmission and clutch is the possibility of separation spline shafts when the breakage of the bolts securing the propeller shaft.

The separation of the shafts can lead to the release of splined shaft and injury to the service personnel. When using the drive on railway transport disconnection of shafts can lead to the creation of an emergency, when the train moves.

Technical result achieved from the use of the present invention is to avoid separation spline shafts during operation, as well as providing the ability to move the lubricant to the track for moving the spline coupler during operation of the transmission device rotation.protective cover on the end-side seals are made with the tab, located with the possibility of contact with the protrusion made on the slotted end of the other shaft, and the protrusion of the casing may be formed by a collar screwed on him nuts, and at the end of one of the shafts may be mounted on the wall, bounding the cavity of the elastic shaft chamber for lubrication.

To achieve the specified result, the clutch is equipped with a device for limiting the relative longitudinal movement of the shaft and one of the coupling halves, which are made as separate parts, connected element having a strength less than the strength of the United elements of the coupling, where one of the coupling halves may be made in the form of covering the end of the shaft sleeve with the annular ledge located with the contact mounted on the shaft limiter in the form of rolling elements or elastic split ring, placed in the annular groove of the shaft, and an element connecting the shaft and the coupling may be made in the form of at least one rod, passing through made holes in them, and the other end of the coupling halves can be located with the opportunity to interact with the butt of the shaft while the breakage of the element,

The essence of the invention is illustrated by drawings.

adressage rings.

Device for transmitting rotation consists of clutches 1 and 2, which are connected with the shafts 3 and 4. The shafts 3 and 4 are interconnected slotted connection 5, closed from falling precipitation casing 6, which is mounted on the shaft 3 and is in contact with the seal 7 with the outer surface of the shaft 4. The cover 6 is screwed the nut 8 with the collar 9 mounted on the possibility of contact with the protrusion 10 of the shaft 4.

At the end of the shaft 3 is fixed to the partition 11, bounding in the shaft 4 moves the camera 12 to lubricate the splines.

The coupling includes coupling halves 13 and 14, interconnected, for example, by bolts. The coupling is made in the form of a sleeve, which is connected to at least one rod 15 with the shaft 16. The sleeve has an annular ledge 17 in contact with the limiter in the form of rolling elements 18 or split ring 19 arranged in the annular groove of the shaft 16.

The operation of the device for transmitting rotation is as follows:

The rotation is transmitted through the coupling 1 and 2, universal joints, shafts 3 and 4. When changing the distance between the coupling extension transfer occurs due to displacement of the shafts 3 and 4 relative to each other by spline connection 5. With the rotation of the grease is placed in the moving lubricating bushing providing constant lubrication in splined connection. In the destruction of the elements connecting the coupling between them, the design does not allow disconnection of shafts 3 and 4 between themselves and fall of one of them, since this is prevented by the shoulder 9 and the protrusion 10 of the shaft 4.

The clutch works as follows:

During emergency braking or a sudden change in speed of the vehicle appears the moment of resistance to rotation of the drive coming from the slowing rotation of the wheel pair. However, the bolting flanges of the coupling affects the drag torque, which tends to shift the flanges and cut the bolts. The same forces act on the rods 15. The rods 15 have a lower tensile shear than the bolts connecting the coupling halves together.

In some cases, the strength of the rods on the slice may also be less than the force required for detachment of the bolt heads. Thus, in the event of extreme efforts are cut rods 15, and the connection of the coupling between them remains unchanged.

In the destruction of the rods 15 is not the end of the shafts, because this is prevented by the annular ledge 17 and the restrictors 18 or 19. In addition, the>Technical and economic indicators: implementation of the actuator and clutch on railway transport will help reduce the frequency of failures and supply wagons in the setoff repair, to reduce labor costs during maintenance operation and routine repairs, reducing delays of passenger trains on the route for a drive fault.
