Abstract
A lubrication system is disclosed for a one-way clutch of the type that lubeoil is fed into the one-way clutch by shaft-center oiling or under a centrifugal force. The lubrication system comprises oil grooves and an oilway. The oil grooves are formed in an inner peripheral wall of at least one of end bearings arranged on axially opposite sides of the one-way clutch, respectively, whereby lubeoil is drawn into the one-way clutch through the oil grooves. The oilway, on the other hand, opens through an outer peripheral wall of an associated inner ring in a region where the outer peripheral wall of the inner ring and the inner peripheral wall of said at least one end bearing undergo relative sliding motion. The outer peripheral wall of the inner ring is free of any oilway opening in a region where associated sprags are operatively brought into sliding contact with the outer peripheral wall of the inner ring.
