A shaft coupling for a drive shaft (3), with a driving and a driven coupling
component in which the driving or the driven coupling component is configured to
form a cylindrical hollow coupling outer member (8) and the other coupling
component configured to form a cylindrical coupling inner member (9), the
two members being disposed so as to be coaxial with the longitudinal axis of the
shaft coupling, and in which axially parallel grooves (27, 28) that are
provided with right- and left-sided side walls (19, 20, 21, 22) are formed
on the inner circumference of the coupling outer member (8) and on the outer
circumference of the coupling inner member (9) for receiving rolling members
(11) that drivingly and axially slidably interconnect the coupling outer
member (8) and the coupling inner member (9), whereby the right-
and left-sided side walls (19, 20, 21, 22) of the coupling inner member
(8) and of the coupling outer member (9) are disposed side by side
and mesh together thereby in such a manner that, together with a side wall (19,
20) of a groove (27) of the coupling inner member (9), a respective
one of the side walls (21, 22) of a groove (28) of the outer member
(8) defines and/or forms a rolling member passage (13, 14).
