PIVOT JOINT OF EQUAL ANGULAR VELOCITIES BY STAROVEROV (VERSIONS) Russian patent published in 2014 - IPC F16D3/30 

FIELD: machine building.

SUBSTANCE: pivot joint consists of an outer (2) and an inner (4) races, balls (3) and a separator, a shaft (5) of the inner (4) race is fixed in it longitudinally and movably by splines, keys, balls or rollers. The second version implies that the outer (2) race is fixed longitudinally and movably in a sleeve (1) connected to the working shaft. Fixation is carried out with the help of splines, keys, balls or rollers. The keys can be round, and the balls can be fitted with separators, in particular, made as insertions from antifriction material, for example, fluoroplastic or bronze. The rollers can also be fitted with separators made as insertions from antifriction material or separators made as a plate with rectangular openings.

EFFECT: increase of service life for a pivot joint of equal angular velocities with longitudinally movable races by several times.
