DEVICE FOR CONVEYING ROTARY MOTION FROM A DRIVING TO A DRIVEN SHAFT

摘要

A high-torque high-ratio transmission comprises a housing provided with a rigid annular surface with teeth juxtaposed with the teeth of a flexible element connected to a slow shaft. The fast shaft has a flange provided with a groove of varying depth in which an array of balls is guided, the balls pressing the flexible element against the housing crown of teeth as the rapid shaft is rotated. The flange of the rapid shaft can be braced by another set of balls on the opposite side thereof.
