摘要：A conveyor roller drive device is provided to mechanically prevent conveyedgoods from falling down on a conveyor system. The conveyor roller drive device includes

a power generator for generating rotational power and a coupling portion which iscoupled to a conveyor roller. A traction roller transmission mechanism is disposed in therotational power transmission path between the power generator and the couplingportion. The traction roller transmission mechanism includes a sun roller, planetaryrollers disposed on the periphery of the sun roller to roll in contact with the sun roller, aring roller for allowing the planetary rollers to roll in contact with the inner peripherysurface of the ring roller, and a carrier being in phase with the revolution component ofthe planetary rollers. Any one of the sun roller, the ring roller, and the carrier isemployed as an input element for receiving rotational power, another one employed asan output element for outputting the rotational power, and the remaining one employedas a fixed element.
