Independently steerable idler pulley

摘要

An independently steerable idler pulley is operable by the means of a non-concentric adjustable inner sleeve bushing mounted interiorly of a radial ball bearing fitted within the ID of the pulley, with the sleeve bushing and bearing and pulley press fitted as an assembly for mounting on an idler shaft. The sleeve is movable in defining the angular alignment adjustment of the assembly with respect to the shaft upon which it is mounted. With the desired angular adjustment determined the sleeve is locked upon the shaft. Plural of such pulleys supported on a common shaft can be individually positioned.
