Method and device for checking gears by measuring the ball size

摘要

Method and device for checking gears by measuring the "ball size", particularly intended for the automatic checking of shaft toothings equipped with one or more toothed wheels, the modulus and pitch circle of one of the wheels of which may be different from those of the other wheels, by selecting and engaging a spindle (broach) with a spherical end in the gap between teeth of the wheel to be checked and by giving the said wheel an alternating rotational movement and continuously measuring the value of the radius measured. <IMAGE>
