Description

The invention relates to mechanical engineering and can be used in stepper motor drives.

The known damping coupling is a Cardelis, consisting of two coupling halves, interconnected by cylindrical helical springs, which rest on segments, which are mounted on the fingers, and the helical springs are installed with a limit tension J.

The disadvantage of this coupling is that it has a low damping capacity and cannot be used, for example, in screw mechanisms with a stepper motor, in which significant forced oscillations occur.

The closest technical solution to the invention is a damping coupling, containing two coupling halves placed between sectors with holes and springs installed in them, the cavity between the coupling halves is filled with liquid.

The disadvantage of such a coupling is its irreversibility, as a result of which it cannot be applied, for example, in the screw mechanisms of the CPS drive for nuclear reactors.

The aim of the invention is to expand the functionality.

The goal is achieved by the fact that the coupling is provided with plungers, the leading coupling half is made in the form of an impeller, the edges of which are located between sectors mounted on the driven half-coupling, while the plungers are installed in the openings of sectors and spring-loaded in the direction to the edges of the impeller, and the cavities between sectors are connected between a throttling channels.

FIG. 1 depicts the proposed

15 clutch, cross section; FIG. 2 the same longitudinal section.

The damping coupling consists of two coupling halves - a leading 1 and a driven 2, interconnected by means of a bearing 3 mounted on the flange 4 of the driven half coupling 2. The coupling half 2 is a cylindrical housing 5. The base of such a cylinder is flag 4. Four sectors 6 are rigidly fixed on body 5. In the spaces between sectors 6, holes are made in the flange 4 for filling the sleeve with liquid. In sectors 6 there are 30 versts 7 directed towards

each other, in the holes x 7 installed plungers 8 with coil springs 9.

The driving half coupling 1 is an impeller. The ribs of the impeller 1 are located in a cavity between sectors 6, Between the case 5 and the ends of the ribs of the impeller 1, and between sector 6 and the shaft 10 of the impeller 1 there are channels 11 for the flow of fluid from one cavity to another. On the side of the drive shaft 10 in the housing 5, a cover 12 is rigidly fixed, a limiting cavity of the coupling,

The damping clutch operates as follows. The torque from the drive shaft is transmitted to the drive coupling half. The impeller 1 compresses the springs 9 through the plungers 8, at the same time, the torque is transmitted to the driven coupling half 2 and then through the slots to the driven shaft of the drive.

Coupling cavities formed by the half couplings and sectors are filled with water

When the impeller 1 is rotated, the water in the channels 11 is displaced from one cavity to the other, and part of the energy of the forced oscillations is compensated for.

At a certain moment, the springs 9 begin to unclamp and rotate the housing 5 relative to the impeller 1 to the initial state. Due to the elasticity of the springs of 9 cm, the shocks, shocks from the operation of, for example, a stepper motor, are partially damped.

The advantage of the damping clutch is that it allows the transmission of torque both clockwise and counterclockwise. The damping clutch has a small twisting angle of the drive half coupling relative to the driven one, which allows its use in reverse mechanisms with small angular discrete movements.
