SU504896A1 - Centrifugal coupling - Google Patents

Description

one

The invention relates to the field of mechanical engineering and can be used for reserving electric motors in electromechanical devices, devices, etc.

A centrifugal clutch is known, containing concentrically located driving and driven coupling halves, interacting by means of centrifugal jamming elements mounted between them, held by a magnetic adjusting device. The leading half-coupling has figured dredging in which the jamming elements made in the form of balls are placed.

However, when opening half couplings at high speeds, significant dynamic loads occur, rapid wear of the wedging elements occurs, as a result of which the reliability and durability of the coupling are reduced. This prevents such a clutch from being used in mechanisms with high rotational speeds.

In order to reduce dynamic loads when opening the coupling halves, the described clutch is equipped with discs fixed at the ends of the leading coupling half and having inclined grooves in the periphery, and the centrifugal jamming elements are made in the form of rollers with axles free-sliding in the said grooves.

FIG. 1 shows the described coupling, a longitudinal section; in fig. 2 is a section along A-A in FIG. I. The clutch consists of the leading coupling half 1 and

concentric with the installed drive half coupling 2. On the driving coupling half, at the ends, there are rigidly fixed disks 3 having inclined grooves 4. The rollers 5 have axes 6 that slide in inclined grooves. The rollers themselves are placed in the shaped hollows 7 of the leading half-coupling. In the driven coupling half grooves 8 are made.

When the driving half coupling 1 rotates, the rollers 5 under the action of centrifugal force move to the periphery and fall into the grooves 8 on the driven coupling half 2, wedging it with the driving coupling half. When the engine is turned off, the leading half-clutch decelerates, and at the same time knowing the half-clutch pushes

rollers 5 in inclined grooves 4, smoothly transfer them to their original position. The angle of the collision of the rollers and the leading half-coupling during wedging is determined by the angle of inclination of the grooves 4 on the disks 3.
