Description

one

The invention relates to mechanical engineering.

A known elastic coupling comprising two flange half couplings connected by elastic fingers mounted in openings Ij.

The disadvantages of this coupling are large dimensions.

Closest to the proposed elastic coupling, containing two coaxial interchangeable couplings with cams at the ends and an elastic element in the form of an asterisk 2 J. located between them.

The disadvantages of this coupling are low energy consumption, since only half of the sprocket rays and the absence of safety properties are involved in the work.

The purpose of the invention is to increase energy intensity and expand operational capabilities.

The remaining target is achieved in that each of the half couplings is made with a number of cams equal to the number of rays of the sprocket, the cams of one half of the coupling are located opposite the cams of the other with an axial clearance between them, and the rays of the asterisk are located in the hollows between the cams.

FIG. 1 shows the coupling, general view; in fig. 2 shows section A-A in FIG. one.

The clutch consists of two interchangeable couplings 1 and 2 with cams 3 and. 4 at the ends. The number of cams on each of the half couplings is equal to the number of rays on the asterisk 5. The cams 3 half couplings 1 are located opposite the cams 4 half couplings 2 with a gap C between the ends. In the hollows between the cams are the rays of an asterisk 5.

The clutch works as follows. When rotating the half-coupling 1, with its cams 3, it pulls the sprocket 5 into motion, showing through it the pressure on the cams 4 of the half-coupling 2 and causing its rotation. In this case, under the action of circumferential effort occurs

elastic deformation of the rays of the sprocket 5, which ensures the elasticity of the load transfer between the coupling halves. Asterisk 5 works for shear, resulting in increased power consumption of the coupling

and its ability to dampen vibrations and shock loads. Circumferential force is transmitted through all the stars of the star-daughter. If you need to protect the car from damage the size of the asterisk

are selected so that when
