Abstract

The invention relates to the field of engineering, in particular to the freewheel couplings. The purpose of the invention is to simplify the design and increase the reliability of the coupling by using magnetic forces to press the rollers against the inserts. The clutch contains outer 1 and inner 2 plates, inserts 3 and rollers 6. Inserts 3 and rollers 6 are made of permanent magnets. The poles of adjacent inserts 3 are of the same name. The poles of the rollers 6 are opposite to the poles of the inserts 3, with which they contact on the working surfaces 4. When the casing 2 rotates clockwise, the rollers 6 freely roll over it and press the magnetic forces of the inserts 3 to the profile working surfaces. When rotating it counterclockwise, the rollers 6 are wedged and the moment is transferred to the holder 1. 4 Il. JV s oo ate about 5 figure 1

Description

The invention relates to mechanical engineering, in particular to a free-wheeling roller clutch.

The purpose of the invention is to simplify the construction and increase the reliability of operation, which is achieved by using magnetic forces to press the rollers to the inserts.

FIG. 1 shows the proposed coupling; in fig. 2 shows section A-A in FIG. one; in fig. 3 embodiment of the coupling without fastening the inserts in the clips; in fig. 4 shows a section BB in FIG. 3

The clutch contains outer 1 and inner 2 cages, inserts 3, made in the form of magnets with shaped working surfaces 4 and installed in the grooves 5 of the outer cage 1, rollers 6, placed in the space between the cages 1 and 2 and inserts 3, in contact with the last ones on the working surfaces 4. The mutual position of the sleeves 1 and 2 is provided, for example, by rolling bearings (not shown), the rollers b are prevented from axial displacement by the covers 7, fixed by screws 8 on the yoke 1. The inserts 3 and the rollers 6 are arranged so that poles of adjacent inserts 3 different us, and the rollers 6 opposite poles with the poles inserts 3 facing the framework 6 profiled surfaces 4.

FIG. 3 and 4 show an embodiment of the coupling, characterized in that the inserts 3 are mounted between the sleeves 1 and 2 without being fastened to the latter.

The clutch works as follows.

When the inner ring 2 is rotated clockwise, the rollers 6 freely roll over its surface, pressing the magnetic fields of the adjacent inserts 3 to the profile working surfaces 4 (the inserts 3 facing the rollers with the profile working surfaces 4 attract them, and the adjacent the inserts 3 push the rollers 6 away from themselves), and the vrash, the momentum onto the yoke 1 is not transmitted.

When the holder 2 is rotated counterclockwise, the rollers 6 are wedged between the inserts 3 and the holder 2, and the torque is transmitted to the holder 1.

When the cage 2 is rotated clockwise (Figs. 3 and 4), the rollers 6 freely roll over the casing 2, while pressing the magnetic fields of the inserts 3 to the profiled working surfaces, and the torque is not transmitted to the cage 1. When the holder 2 is rotated counterclockwise, the rollers 6 are wedged between the holder 2 and the inserts 3, pressing the latter to the holder 1, the torque is transmitted to the holder 1.
