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

Yoke for universal joint

A line guide bracket for adjustably coupling a holder to a ground stake is disclosed wherein the bracket is formed from flat metal sheet stock into a tubular structure and includes apertures having centering notches for accommodating ground stakes and holder arms of different diameters.

Line guide bracket and method of making same

A process for manufacturing a universal joint mainly by cold forging which comprises a blanking step to punch out a blank having a pair of fork member portions projecting from one side thereof and a hub member portion out of a sheet metal or coiled sheet metal material, a press-working step to form bolt holes on the lug member portions and projections on the opposite side thereof by extrusion, a forming step to bend each root portion of each pair of fork member portions to bring them to a fixed height from the hub member portion, a primary bending step to form the hub member portion into a cylindrical shape, a secondary bending step to project the lug member portions in parallel to each other from said cylindrically shaped hub member portion after completion of the primary bending step, and a press-reforming step to straighten the configuration of the formed product after the secondary bending step.

Process for manufacturing universal joint

A yoke for universal joint is composed of a cylindrical coupling tube formed by pressing a metal plate and having a slit in a radial direction and serrate grooves on the internal periphery; a pair of flanges integrally formed at an end of the coupling tube and positioned on both sides of the slit; and a coupling arm formed by pressing a metal plate One of the flanges has a screw hole, while the other flange has a hole, coaxial with the screw hole, for passing a bolt to be screwed into the screw hole The coupling arm has a penetrating hole in the base portion, and mutually coaxial circular holes at its opposite ends The yoke is assembled by fitting the other end of the coupling tube into the penetrating hole in the base portion, and connecting the other end of the coupling tube with the base portion of the coupling arm

Yoke for universal joint and manufacturing method therefor

A clamp yoke (10) formed from a flat piece of metal. The flat piece (5) being approximately T-shaped which is bent into the clamp yoke. The top portion of the T forming the yoke ears (24) and the vertical portion forming two approximately parallel shaft portions (12, 14). The yoke ears each having a bearing bore (26) therein and the shaft portions each having a shaft receiving bore (20) therein. The clamp yoke can be provided with a bolt (30) having a reduced diameter middle which allows a shaft to be inserted into the shaft receiving bores without removing the bolt. The bolt is then tightened, drawing the larger diameter portion into the center of the clamp yoke where the bolt engages a transversely relieved portion on the shaft to axially retain the shaft.

One-piece stamped clamp yoke

The yoke formed by the blanking and rolling of a blank comprises branches 1, 2 and a hub 23 which is provided at the end thereof remote from the branches of the yoke with a guiding chamfer for a shaft adapted to receive the yoke. The chamfer 10, 12, 16, 17 is formed by a cold stamping operation.
