Torque-transmitting devices

摘要

A torque transmitting devices has an input shaft having two axially-spaced sets of external splines. Two internally splined members are threadedly interengaged and respectively engage the spline sets on the shaft. The angular positions of the members are adjusted by spacers so that the portion of the shaft between its spline sets is in torsion, the direction of the torsion being such as to increase the threaded engagement between the members.
