ABSTRACT:
A roller assembly comprises an essentially cylindrical spindle which is rotatably supported at opposite ends by a pair of end assemblies. The spindle has brush elements on a circumferential surface and axial bores extending inwardly from each of the ends. Each end assembly comprises a shoulderless cylindrical stub shaft which is coaxial with and rotatable with the spindle, a bearing frictionally mounted on an outer end of the stub shaft, and a non-rotating end cap which may be mounted in a vacuum cleaner chassis member, such as two opposite side walls of a vacuum cleaner nozzle. The stub shaft comprises along its axial length a smooth inboard portion, a roughened middle portion which frictionally engages a bore wall, and a smooth outboard portion which extends beyond the end of a spindle. The bearing is mounted on this outboard portion. The end assembly may also include a thread guard and a washer which rotate with the spindle. An annular shoulder surrounding the open outer end of the bore positions the bearing. The end cap may have an axially inwardly extending flange which forms a receptacle for the bearing, and the spindle may have a counterbore extending axially inwardly from each end to provide a recess for the bearing and this flange. The roller assembly can be readily built to close tolerances in overall length, bore depth, and stub shaft diameter, and with a high degree of concentricity, thereby minimizing both bearing wear and vibration.
