Abstract: A yoke includes a body having a pair of yoke arms that are adapted to receive a cross member of a universal joint. The body includes a stiffness ring extending radially outwardly from an outer periphery of the body at least in regions of each of the yoke arms.

Abstract: The outer peripheral surface (32) and the inner spherical peripheral surface (34) of a cage (30) of a double-offset constant velocity universal joint are cut after being quenched. More specifically, to finish the outer peripheral surface (32) of the cage (30) made up of a spherical portion (32a) and tapered portions (32b, 32c), the spherical portion (32a) and the tapered portions (32b, 32c) are cut after being quenched. Then, the spherical portion (32a) is cut at a cutting speed lower than that for the tapered portions (32b, 32c), thereby providing a better roughness to the cut surface of the spherical portion (32a) than to the cut surface of the tapered portions (32b, 32c).

Abstract: A drive shaft is provided with a sleeve enclosing at least sections thereof. The sleeve is fixed to the drive shaft in order that it may rotate with the drive shaft. The sleeve forms a heat shield with heat-reflecting and/or heat-insulating properties. This serves to effectively reduce the heat input into the drive shaft. In contrast to conventional heat shield plates, the problem of fixing is eliminated. Moreover, a heat shield sleeve according to the invention can also still be fitted in situations wherein the space is too restricted for a heat shield plate. In addition a savings in weight and material also results.

Abstract: An injection molded plastic guard is used to enclose a coupling connection between a prime mover input shaft and a driven output shaft. The guard is comprised of two halves that are hinged together with a stainless steel pin at one end. The coupling is centered within the guard with the hinge being positioned above the coupling. The halves extend from the hinge to distal ends that are pivoted about the pin to surround and enclose the coupling. The distal ends meet underneath the coupling area and are mounted to a non-rotating base. Sleeves extend outwardly from opposing ends of the guard to surround the input and output shafts and abut against the prime mover and output device equipment. The sleeves have a vertically, elongated opening so that one guard can be used to cover many different base-to-shaft heights. Further, the length of the sleeves can be adjusted to accommodate different centerline-of-guard to equipment face distances.

Abstract: The invention is a piping to component component connector system including forged flange which has a groove and raised portion in place of the conventional weld neck construction. The groove and raised portion allow the flange to be connected to associated piping by mechanical means rather than by welding. Forged flanges, with their high strength and quality, can be employed in piping systems without the attendant high expense of field welding the flange to its associated piping.

Abstract: An universal joint dissipates shock and reduces torsional vibration to the elements of the universal joint. An elastomeric material, such as a polyurethane, is introduced between the bores of the yokes of the joint and the respective adjacent bearing cups that are mounted on the shafts of the cross bar.

Abstract: In an arrangement for mounting a tubular member, such as a part of a dynamic damper or a dust boot, made of elastomeric material onto a shaft member, an annular projection is formed integrally on the inner circumferential surface of the tubular sleeve member, and an endless band made of relatively rigid material such as steel is either insert molded in or fitted on the tubular sleeve member so as to surround the annular projection. The outer diameter of the shaft member is smaller than the inner diameter of the endless band, but is greater than the inner diameter of the annular projection. Therefore, the elastomeric tubular member can be firmly fitted onto a shaft easily and economically. Because the endless band can be made of a seamless solid ring or a welded ring, it is more reliable in use than conventional steel band fasteners. Since the endless band is uniform over its entire circumferential length, it is free from any rotational imbalance.
