Abstract

The axle (5) with an inner bearing ring (2) secured to it is stationary, whilst the housing (6) with an outer bearing ring (3) secured to it is rotatable. An oil inlet (8) leads into a ring-shaped inlet chamber (11) on one side of the bearing (1), whilst an oil exit chamber (12) is located on the other side of the bearing. The inlet chamber is defined by a cavity between the housing, axle and bearing, and it increases in size towards the oil exit chamber side of the bearing.
