摘要： An outside ring manufacturing method comprises a first step of blanking out from a metal sheet a blank with a circular body portion and tongue portions which protrude at several places from the outer peripheral edge of this body portion, a second step of press forming the blank so that the body portion is formed into a tapered cylinder portion which tapers off or decreases in diameter with the distance away from the tongue portions and so that the tongue portions are made parallel to an axis of the tapered cylinder portion, a third step of adjusting the geometry of each part to a predetermined geometry through the machining of an end surface of the tapered cylinder portion and the tongue portions, and a fourth step of heat treatment to achieve a desired hardness.

摘要： A universal joint yoke comprises: (a) a generally cylindrical connecting part made by press-forming a metal plate and having internal peripheral serrations, a first end portion at which edges of the metal plate are brought into abutment to form a tubular abutting part, a second end portion with a pair of flanges disposed at opposite sides of an axial gap and facing one another substantially in parallel, and a pair of reentrant cut-outs with a respective one of the cut-outs being disposed between each flange and the abutting part, and (b) a pair of diametrically opposed connecting arms integrally formed with the first end portion of the connecting part and extending axially outwardly from the first end portion of the connecting part. One of the flanges is provided with a tapped hole and the other of the flanges is provided with a through-hole coaxial with the tapered hole for passing a bolt to be screwed inito the tapped hole. Each connecting arm is provided with a respective through-hole, and the respective through-holes of the connecting arms are coaxial.
