Description

(54) CLUTCH WITH DYNAMIC ECCENTRICS

one

The invention relates to the field of engineering.

A clutch with dynamic eccentrics is known, comprising two flange half couplings, on which fingers are fastened and bushings mounted on them, interacting with each other.

However, this clutch does not work reliably when the shafts are joined. The lack of OPPORTUNITIES for adjusting the position of the fingers and the impossibility of disassembling the coupling without dismantling the connected units reduce its operational properties.

The purpose of the invention is to improve the reliability of the proposed coupling with the skews of the connected shafts and to improve its operational PROPERTIES.

For this purpose, in the proposed coupling, the sleeves are made with a spherical outer surface and are mounted on fingers with a radial eccentricity about the axis of the fingers; The fingers are fixed on the half couplings in the radial grooves with threaded elements and washers, while the contacting surfaces of the washers and the flange are made obliquely angled, inhibiting the movement of the fingers.

FIG. 1 shows the proposed coupling with dynamic eccentrics; in fig. 2 is a section along A-A in FIG. one.

The coupling consists of two flange coupling halves 1, 2, pins 3, fixed with threaded elements 4 and washers 5. Fingers 3 are fitted with bushings 6 with eccentricity e. Bushes 6 have a spherical surface 7.

At a low speed of rotation, the coupling half is transmitted through bushings that have the OPPORTUNITY to unfold on the fingers and compensate for the misalignment of the shafts.

Upon reaching a high speed of rotation of the coupling half sleeves impart to the coupling the elastic-dynamic properties due to the centrifugal

strength
