Abstract:
A relubricatable idler bushing assembly comprising:an idler bushing having an axial through bore defining an inner surface for the idler bushing;an inner bushing extending within the through bore, the inner bushing having first and second end portions of a reduced diameter and an outer surface of the inner bushing intermediate said first and second reduced diameter ends spaced apart from the inner surface of the idler bushing, defining a lubricant passageway, the inner bushing having an axial through bore; anda spindle dimensioned to be received within the through bore of the inner bushing, the spindle having an axial passageway therein and a radial bore communicating the axial passageway with the outer surface of the spindle, one end of the spindle being adapted for supplying lubricant under pressure to the axial passageway, the axial passageway being in fluid communication with the lubricant passageway along a fluid flow path defined in part by the inner bushing, andfirst and second bearings interposed between the idler bushing and the inner bushing permitting relative rotational movement between the idler bushing and the inner bushing, the first and second bearings being in fluid communication with the lubricant passageway,the first and second reduced diameter ends of the inner bushing cooperating with ends of the through bore of the idler bushing to define first and second recesses for locating the first and second bearings, respectively.
