HUB ASSEMBLY DRIVEN BY MOTOR FOR TAPE CONVEYOR

摘要

A self-contained reel hub assembly for a tape transport. The hub assembly comprises a housing including a base and a side wall which upstands from and extends around the periphery of the base. Within the housing defined by the side wall is the rotor and the stator winding of a motor. The rotor drives a sun wheel which engages a plurality of planet wheels each of which protrudes laterally from the side wall of the housing. A rotatable hub is mounted on a central post extending upwardly from a frame member forming a top cover for the housing. The hub member includes a peripheral part which extends around the side wall of the housing and carries a ring of inwardly directed gear teeth engaged by the planets. The planets are linked by a carrier which permits limited movement of the planets relative to the carrier.
