SU1751525A1 - Disc clutch - Google Patents

Abstract

Use: limiting the magnitude of the transmitted torque with simplified adjustment of the magnitude of the latter. SUMMARY OF THE INVENTION: The half-couplings in the form of discs are installed with the possibility of frictional interaction between the ends and are spring-loaded one to the other with at least one elastic periphery installed at the periphery in the form of a bracket in contact with the free ends with opposite ends of the first section of the first-third.

Description

The invention relates to mechanical engineering, in particular, to the protection of structural elements against transmitted limiting torques.

The known safety friction clutch, which contains the driving and driven half couplings, is connected by means of friction and pressure disks, a torque adjustment unit and a device for accommodating disks.

Closest to the present invention is a disk clutch comprising two coupling halves, one of which is mounted with the possibility of axial movement. The coupling halves are made in the form of discs and are spring-loaded with ends by means of elastic elements with the possibility of frictional interaction with these ends, and the elastic elements are located on the periphery of the disks.

The disadvantage of this coupling is the complexity of the design and the complexity of tuning to the required torque.

The purpose of the invention is to improve the performance properties by simplifying the design and simplifying adjustment of the transmitted torque.

The essence of the invention is as follows.

Each spring compresses the disks of the coupling halves with a certain force and, placing the required number of brackets on the disks, regulate the force of pressing the disks to each other, i.e. friction force and transmitted torque. At a certain torque, the disks of the coupling halves turn one relative to the other, but as soon as the magnitude of the torque decreases, the friction increases in the disks and the normal contact is restored.

Figure 1 shows a disk clutch, a cut; 2 is a spring clip: FIG. 3 is a disc clutch, general view.

The disk clutch consists of disks 1 half couplings 2, compressed with spring clips 3. The latter have spikes 4 which mate with notches 5 on disks 1.

The device works as follows.

The coupling halves 2 are fixed on the shafts and the disks 1 are connected by spring clips 3. For tuning for a certain torque, a certain number of brackets 3 are placed on the disks 1 of the half couplings 2. To prevent the brackets 3 from popping out, spikes 4 are made on the disks 1, and notches 5.

When a certain moment is exceeded, the discs 1 of the overshoot / overwire one relative to the other and the transmission of the torque is stopped.
