SU1245782A1 - Slip coupling - Google Patents

Description

The invention relates to mechanical engineering and can be used in transmissions of mechanisms for protecting parts from overloads.

The purpose of the invention is to increase the load capacity and smoothness of operation by reducing the stresses in the elastic link in the process of slipping.

FIG. 1 shows the coupling, transverse section; in fig. 2 - section AA

FIG. one.

the safety coupling contains an inner coupling half 1, made with diametrically opposed segmental grooves 2, mounted concentric with its outer coupling half 6 and

prestressed high-stability design of low labor intensity of manufacture and weight.

The safety coupling works in the following way.

When the leading half coupling, for example half coupling 1, rotates, the torque through a closed elastic link (rigidly connected to the outer coupling half 3 and interconnected by means of concave sections 8 and 9 with segment grooves 2 of coupling half 1) is transmitted to the driven coupling half 2. At the moment an overload occurs (for example, abrupt stopping of the driven half coupling 2) sections 8 and 9 of the connecting link as a result of the elastic deformation of the latter. .rwii-4iTj 1.r GGL TTL / L / lTtTI-J I
