SU587279A1 - Cross-crank coupling - Google Patents

Description

one

The invention relates to mechanical engineering.

Couplings are known, comprising two coupling halves with end lugs and an intermediate rectangular cracker connected to them by elastic elements Jjl

These couplings are difficult to manufacture and assemble.

Cross-rocker couplings are also known, which contain leading and driven coupling halves connected by an intermediate element by means of cylindrical protrusions that enter the grooves and are located in mutually perpendicular planes 23.

This coupling is the most interesting to the invention by its technical essence and the achieved result.

The disadvantage of such couplings is design complexity.

The purpose of the invention is to simplify the design of the coupling.

For this, the intermediate element of the proposed coupling is made in the form of a sleeve, and the grooves are located radially at its ends, while the cylindrical protrusions are made on the outer surface of the coupling halves.

In addition, each protrusion of the half-coupling is equipped with an axle mounted on it, made in the form of crackers of a prismatic shape.

FIG. 1 shows the described coupling with a partial cut; Fig.2vid above the coupling with the installation of crackers.

The coupling comprises an intermediate element 1 in the form of a sleeve and two coupling halves 2 and 3 with cylindrical protrusions 4 on the outer surface entering grooves 5 located radially at the ends 1 in mutually perpendicular planes.

To increase the carrying capacity of the coupling on each protrusion 4, a holder b in the form of crackers of a prismatic shape can be installed.

Crackers can be made of bronze, cast iron or textolite with thermo-matched matching surfaces. At considerable wear of a cracker its opposite sides can be used.

The design allows for a quick change of worn crackers.

The operation of the coupling is as follows.

Claims (2)

When one of the half couplings is rotated, the torque is transmitted through its protrusions to the intermediate element 1 and then to the other half coupling. The clutch ensures the operation of almost any error of assembly. Claims of the invention A cross-coupled coupling comprising a drive and a driven coupling half, connected by an intermediate element by means of cylindrical protrusions entering the grooves and arranged in mutually perpendicular planes, characterized in that, in order to simplify the design, the intermediate element is made in the form of bushing The grooves and grooves are located radially at its ends, while the cylindrical protrusions are made on the outer surface of the coupling halves. 2.
