Shaft coupling with inclined ball location grooves - has cage for ball location at varying shaft angles

摘要

A shaft coupling, consisting of an inner (4) and an outer (3) coupling ring has also a ball cage ring (2) which carries a number of coupling balls (1). Semi-circular grooves (6) on the inside of the outer coupling ring (3) are inclined relative to the coupling axis. identical grooves (7) on the inner element (4) are inclined in the opposite direction so that together with the outer coupling element (3) locations for coupling balls are formed (1). A ball cage (2) which retains the balls (1) axially, enables the coupling to transmit torques between shafts of varying angular alignment and in both rotational directions.
