Description

one

. The invention relates to mechanical engineering.

A cross-link coupling is known, containing two flange half-couplings with grooves on the ends, connected by an exact disk with ridges entering the grooves | 1 j.

The disadvantages of this coupling are. low compensating properties and wear.

A compensating coupling is also known, comprising two flange half couplings with diametrically mounted opposite rollers at their ends, interacting with intermediate element 2.

The disadvantages of the known coupling are the low load capacity associated with high contact voltages and large diametrical diameters.

The aim of the invention is to increase the load capacity and decrease the diametrical dimensions.

The goal is achieved by the fact that a compensating coupling containing two flanged semi-flanges with diametrically mounted opposite their ends with rollers that interact with an intermediate element, is equipped with round rods and additional rollers, the intermediate element is designed as a sleeve, and the rollers are with grooves of a semicircular 10 l on the outer surface, with the rods attached to the ends of the sleeve perpendicular to the axis of the coupling in mutually perpendicular planes, the rollers are located on both sides us from,

15 and the latter are located in joint rollers.

FIG. 1 shows the coupling, general view; in fig. 2 shows section A-A in FIG. one.

The coupling consists of two coupling half 1 and 2 with flanges 3 and 4. Between the coupling half is located an intermediate element 5, made in the form of sleeves. In the intermediate element, round-shaped rods 6 and 7 are fixed in the holes. The rods are covered by rollers 8 with bars of a semicircular profile 9 on the outer surface. The rollers 8 are fixed on the flanges of the half-bridge with the help of axles 10, discs 11, strips 12. screws 13 and 14. The coupling works as follows. The rotating momet from coupling half l is transmitted through flange 4, disk 11, rollers 8, rods 7, intermediate element 5 to coupling half 2. By moving rollers 8 along rod 7, radial displacements of NIN coupling halves are compensated, and rotation of rollers around rods compensates for distortions of axes of coupling half. The clutch has increased load capacity due to the large contact surface of the rollers with the rods. The diametrical dimensions of the coupling are reduced and the safety of its maintenance is increased. Claim Coquetting Coupling containing two flange half-domes with diametrically installed at the ends of the rollers interacting with the intermediate element, characterized in that, in order to increase the load capacity, it is equipped with round rods and additional rollers, the intermediate element is designed as bushings, and rollers; - with grooves of a semicircular profile on the outer surface, with the rods attached to the ends of the sleeve perpendicular to the axis of the coupling in mutually perpendicular polar planes rollers arranged on both sides of the rods, and the latter are arranged in aligned grooves of the rollers.
