Idler gears (14) which transmit power from crankshaft gears (12) to camshaft gears (16) may have helical teeth thus producing a tilting or cocking force on the idler gears (14). Past attempts to solve this problem have led to bulky and expensive structures, or to structures which are subject to failure. The problem is solved herein by a sleeve bushing (38, 54 or 54') having an axially extending bearing surface (42, 58 or 88') and being located between the bore (26,52) of an idler gear (14) or other rotary member and a stub shaft (30 or 56), the sleeve bushing (38,54 or 54') including construction (51 or 60) which maintains an extended area (44,46 or 58,88) of the bearing surface (42 or 58 or 88) in fitted mating relation against an extended area (49, 52 or 97) of a respective one of the shaft (30,56) and the bore (26,52) as the bearing surface (42,58,88') is worn down.
In a bearing arrangement wherein a rotary member (14) is rotatably mounted at a bore (26, 52) therein on a relatively stationary shaft (30, 56), said arrangement having means for biasing said member to tilt about an axis perpendicular to said shaft, the improvement comprising:
