Abstract

A stepping motor causes a driving pinion to rotate by steps of 90 DEG , the stopping position being such that a driven pinion is blocked with a very small backlash by the pressure of a tooth of the driven pinion against the top face of one of the teeth of the driving pinion. Both pinions have simple teeth with conventional profiles capable of being cut by means of a worm-hob. The pitch of the driving pinion is between one and two times that of the driven pinion, and the layouts of the teeth are such that the arc along which a tooth of the driving pinion engages the teeth of the driven pinion includes a portion tranversed freely and a portion along which the driving pinion rotates the driven pinion by one step of its toothing.
