METHOD AND DEVICE FOR MEASURING DIMENSION OF CONSTANT VELOCITY JOINT

摘要

A method and a device for measuring the dimensions of a constant velocity joint. In the method, for example, the cylindrical part (20) of an outer member (12) with a specified offset value is supported on the support part (34) of a dimension measuring device (30) for the outer member. On the other hand, a holding bar (38) is inserted into a recessed part formed in the shaft part (18) of the outer member (12). In this case, balls (40a to 40c) installed at the tip of the support part (34) are inserted into the ball grooves (22a, 22c, 22e) of the cylindrical part (20). In this state, a rotating member (62) is rotated to bring a probe (42) into contact with the inside wall of the cylindrical part (20). The measurement core (106) of a micro gauge (46) is displaced according to the displacement of the probe (42), and the amount of the displacement thereof is displayed as the amount of the variation of the needle of the micro gauge (46).
