YURCHENKO COUPLING OF EQUAL ANGULAR VELOCITIES (EMBODIMENT) Russian patent published in 2020 - IPC F16D3/26 F16D3/18 

FIELD: machine building.

SUBSTANCE: invention relates to machine engineering, and more specifically to the connection of shafts. Coupling of equal angular speeds contains two external links, located between them internal link, twelve rollers, two fixing elements and the ball hinge. Part of surface of rollers is made in the form of truncated cones with their smaller bases facing the common centre. Size of the length of the fixing element between the rollers is equal to the sum of the height of the separated conical parts from these two rollers, and the maximum size of the section of the fixing element does not exceed the least of four diameters of smaller bases of truncated conical surfaces of rollers belonging to the first joint of the external and internal links. Design of internal link makes it possible to install a ball hinge inside. In initial position of coupling two fixing elements and ball hinge are located on common longitudinal axis of coupling, centre of ball of ball hinge is located exactly in middle between centres of first and second connections of external and internal links.

EFFECT: enabling the design simplification.
