ABSTRACT:
A motor-driven overhead trolley conveyor is described which comprises a rail having horizontal sections and inclined sections. Rack sections or chain sections are associated to the inclined sections. Each trolley comprises its own drive motor. In the horizontal sections the driving force is transmitted exclusively through a drive roller. In inclined sections the drive is effected by means of a gear meshing with the rack or chain and being driven with the same angular velocity as the drive roller. The drive roller comprises a drive wheel connected with the drive shaft as well as a ring mounted on the periphery of the drive wheel in a slide bearing fashion. By this feature, a cold working of the drive roller surface and the rail surface due to alternate stresses caused by the gear is avoided.
