ABSTRACT:
A structure for mounting a rotating machine element, such as a drum pulley, idler, roller or the like includes first and second bearing sets secured to first and second end disks of the rotating member. The first bearing set is secured to a stationary shaft by means of a locking assembly. The locking assembly includes a wedge-shaped sleeve or adapter which is secured between the inner race of the first bearing set and the stationary shaft. During installation of the locking assembly, the second bearing set remains slidable along the shaft, thereby avoiding pre-loads or stresses in either bearing assembly or the components of the rotating member. Once the rotating member has been fixed in a desired position along the shaft by means of the locking assembly, a retaining element may be placed adjacent to the second bearing set. The structure may be easily disassembled by the reverse process.
