Description

The invention relates to mechanical engineering, can be used in particular on railway transport in drives of undercarriage generators for transmitting rotational motion from the reducer of the wheelset through the driveshaft to the anchor of the generator. The purpose of the invention is to increase operational capabilities. The drive half coupling hub 2 is connected <levers (P) 3 with centrifugal pads. At the ends of the jumpers 5 fixed cargo 7. The ends of the P 3 placed pivotally in the grooves 6 jumpers 5.

When starting, the hub 2 moves the end of P 3 along the groove 6 until it stops. With respect to this pivot point, under the action of the load 7, the cranks rotate before coupling them with the driven coupling half. 4 il.

Invention, relate ?; to mechanical engineering, it is used, in particular, in railway transport, in drives of undercarriage generators for transmitting rotary motion from the gearbox of the wheel set through the drive shaft to the generator anchor.

The purpose of the invention is to increase operational capabilities.

FIG. G shows the clutch, a general view 'in FIG. 2 is a section A-A in FIG. 1, FIG. 3 - block, centrifugal; in fig. 4 shows the clutch in the working position, section A-A in FIG. one.

In the housing 1 is placed the leading half coupling in the form of a hub 2, on which the levers 3 are radially mounted and fixed at one end, concentric to the hub · 2 there is a driven half coupling in the form of a holder 4, towards which the centrifugal pads are made, in the form of jumpers 5 with arc grooves 6, weights 7 with friction linings 8 are installed at the ends of the jumpers 5. The levers 3 with the free ends are placed in the grooves 6 with the possibility of movement. The housing 1 can be connected to the holder 4 shear pins 9.

The clutch works as follows.

At the beginning of the movement of the car at the turn of the hub 2, the levers 3 with their ends will move in the grooves 6 up to the stop, while the holder 4 will remain motionless due to the presence of a gap between the holder 4 and the pads. With further increase in the speed of cargo

7, under the action of centrifugal forces, cause the bridges 5 to rotate around the ends of the levers 3 in the grooves 6, overcoming the spring force. Friction lining 8 enters the clutch with the yoke 4, passing it rotation, Depending on the direction of rotation, the pads with the yoke 4 grip at one or the other end with the load 7. This ensures reliable grip due to the torque at the end of the jumper 5 with the load 7 relative to the pivot point of the lever 3 in the groove 6.

In extreme conditions, the safety pins 9 are cut off when the wagon generator is jammed.

Claims (1)

Claim Centrifugal coupling consisting of a leading coupling half with levers, the driven coupling half arranged concentrically with it, centrifugal shoes, spring-loaded to the driving coupling half, characterized in that, in order to increase operational capabilities, each centrifugal shoe is made in the form of two weights connected by a jumper, in which the arc groove is made, the levers are located radially, one end thereof is rigidly fixed on the leading coupling half, and the other end is installed in the arc groove of the jumper with the possibility of circumferential eniya.
