Description

,one

The invention relates to machine oolast devices and can be used in devices that require a smooth switching off of the IT when transmitting large torques.

A functional coupling is known, the leading and driven half-hems and the stabilizing mechanism, the elements of which operate under the influence of the transmitted torque, which reduces its sensitivity l.

The aim of the invention is to increase the sensitivity of the coupling.

This is achieved by the fact that the coupling is equipped with a concentric tube freely installed in the leading coupling half, the leading coupling half is made with a cylindrical recess on the side of the friction disks, and the end surfaces of the pin and the driven coupling half are conical, while the stabilizing mechanism is made in the form of The deepening of the ring with radial holes installed in the holes of the balls and pushers with tapered rollers, con2

clocks with tapered surfaces of the heel and the driven half coupling, and the cylindrical surface of the leading coupling half is made with grooves that enclose the balls and are angled to the axis of the coupling half and form the cylindrical surface of the depression.

FIG. 1 shows the proposed coupling; in fig. 2 shows a section A-A in FIG. 1. The coupling contains a leading coupling half 1, in the central hole of which, by means of a radial bearing 2. a pin 3 is installed, the conical surface of which and the tapered surface of the driven coupling half 4 mated to the shaft 5 contact the conical surface of the rollers 6, the Rollers 6 freely mounted on the pusher 7 located in the radial holes 8 of the cylindrical ring 9 placed in the cylindrical recess of the leading coupling half, on the grasping surface of which there are inclined to the axis of the coupling (I to the forming cylinder ndrichesksy The surface of the recess grooves 10 fasoE1nye

wrapping balls 11 in contact with pushers 7. Grooves 12 are made on the driven half-half-1, in which friction disks 13 are installed in the center, which are in contact with the leading discs 14 installed in the grooves 15, made on the inner cylindrical surface of the leading pellumufuta. The friction discs are pressed in the axial direction by a spring 16, the force of which is adjusted by the nut 17.

The clutch works as follows. In normal operation, the torque is transmitted through the driving coupling half 1, the driving and driven friction discs to the driven half coupling 4.

At the moment of overload, the knowledge of the half-coupling 4 stops, and the leading coupling half 1 continues to rotate, with its shaped grooves 10 acting on the balls 11. The latter, moving

radially and axially in conjunction with the ring 9, the driven coupling half will alternate to the right, weakening the force compressing the friction discs. There is a relative rotation of the half-wheels, with strict parallelism between the end surfaces of the supporting, pressure and friction discs, which results in a smooth switching on and off of the friction safety clutch.
