Abstract

See full text

A hydraulic drive system readily adapted for either manual actuation or motor-driven actuation due to the unique design of the hydraulic drive and its coupling to either a hand crank or to a motorized drive to provide hydraulic pressure to lift cylinders that can be attached to table legs for vertical adjustment. The hydraulic drive includes a screw jack having an end extending from one end of a housing and splined or otherwise keyed. A manual crank arm or motorized drive assembly includes a coupling which mates with the end of the screw jack to provide a drive force for the hydraulic cylinder drive. The motorized drive assembly includes a pair of toothed hubs and an intermediate flexible sleeve allowing alignment of the motorized drive to the drive assembly as well as providing sound dampening, a cushioned coupling, and facilitates overcurrent detection.
