摘要： A tripod member having three trunnions is inserted in an outer ring. A guide block is supported on each of the trunnions so as to be pivotable around the trunnion and is formed with a ball circulation groove at each side thereof. A plurality of balls are accommodated in the ball circulation groove so that part of the balls will protrude diametrically outwards from the ball circulation groove. The outer ring is formed in its inner surface with raceway grooves for guiding the balls in an axial direction. An arcuate ball rolling surface and a ball guide surface are formed at both sides of each raceway groove to guide the balls and prevent them from dropping out, respectively.

摘要： A cold forged pulsar ring (1) which comprises a ring body (1a) having inner and outer peripheral surfaces. A plurality of circumferentially spaced gear teeth (2) are integrally formed by the use of a cold forging process with one of the inner and outer peripheral surfaces of the ring body (1a) so as to protrude radially of the ring body (1a). Each of the gear teeth (2) is so profiled as to have a substantially trapezoidal shape having a tooth angle (.theta.) not smaller than 5.degree., but not greater than 15.degree.. With this design, not only can a cold forging process be employed to manufacture the pulsar ring (1), but also a required output voltage can be secured from a sensor of the rotation detecting device in which the pulsar ring (1) is operatively employed.

摘要： To make a peripheral lip region to be formed with chamfered portions by the use of a plastic working technique, to enable the use of a cup forming punch of a simplified shape so that a mold used therewith can be easily assembled and the punch when worn down can easily be repaired, a method of making an outer race of a constant velocity universal joint of a tripod type includes an upsetting step during which not only are outer peripheral shapes of a small diameter portion (W3a) and a large diameter portion (W3b) defined, but a recess (Wb) having a tapered peripheral wall face (Wba), which eventually defines general shapes of the chamfered portions (10) of the outer race (1), is formed in an end face of the large diameter portion (W3b). During a cup forming step, the tapered peripheral wall face (Wba) defined during the upsetting step is rearwardly pushed while its shape is maintained. Thereafter, a cup drawing step is carried out to finish the tapered peripheral wall face (Wba) to represent the final design shapes of the chamfered portions (10).
