ONE-WAY SELF-ALINING TORQUE UNIT

摘要

A one-way, self-alining torque unit well suited for heavy duty on a vertical shaft subject to misalinement with respect to coacting torque applying structure. The unit comprises a one-way torque coupling and an alinement coupling integrated together for mounting on a vertical shaft and providing for compensation for misalinement of the shaft with reference to coacting structure which applies torque to the shaft in only one direction through the assembly. Working parts of the alinement coupling and underlying working parts of the torque coupling are continuously bathed in flowing lubricant that descends through a succession of comating working parts all to the end that the unit will operate reliably for many years in locations where access for service is impractical. A reversible cam ring in the unit permits adaption of the unit to transmit torque to the shaft in either direction without structural modification of components of the unit. Interfitting toothed rings accommodate misalinement of the shaft and minimize the overall length of the unit.
