Description

(54) ELASTIC CLUTCH

one

The invention relates to the field of-. mechanical engineering. ,, ..

According to the main author. St. No. known elastic coupling, containing two flange coupling halves with fingers secured parallel to the axis in them by a serpentine spring 1

The presence of the metal contact of the fingers with the spring does not provide this clutch with high elastic to the de-amplifying properties.

In order to increase the elastic and damping properties of the proposed coupling, the sleeves mounted on the plows are provided / the outer surface of which is covered with an elastic material. .

FIG. 1 shows the elastic coupling with a notch, general view; in fig. 2 is a view along arrow A in FIG. one.

The elastic coupling contains a casing 1, the coupling halves 2 and 3, which are located in the casing, on the flanges 4 and 5 of the coupling half rigidly fixed fingers 6 and

7. On the fingers 6 and 7 put on the sleeves 8 and 9, covered with elastic; With material 10, for example, a hard rubber or polymer, the sleeves 8 and 9 are covered by a serpentine spring 11.

The clutch works as follows.

When the driving half coupling 2 rotates, the torque is transmitted through the fingers 6 and the sleeve 8 of the bristle spring 11, then through the fingers 7 and the sleeve 9 to the coupling half 3.

The deformation of the elastic layer on the sleeves increases the elastic and damping properties of the coupling.
