摘要： Provided is a constant velocity universal joint, including: an outer joint member having an opening portion at one end thereof, and an inner joint member configured to transmit torque while allowing angular displacement with respect to the outer joint member through balls, End portions of a boot closing the opening portion of the outer joint member are fastened and fixed to a mounting part of the outer joint member and a mounting part of a shaft extending from the inner j oint member. At a part of an outer peripheral surface of the shaft where at least an inner peripheral surface of the boot is brought into contact when the shaft takes an operating angle with respect to the outer joint member, there is arranged a sliding bearing as an intermediate member configured to reduce abrasion due to friction caused by relative movement between the outer peripheral surface of the shaft and the inner peripheral surface of the boot.

摘要： A shaft coupling guard (100) is used to cover a shaft coupling (50) that couples a main shaft of a prime mover and a main shaft (31) of a driven apparatus as a rotatable apparatus driven by the prime mover. The shaft coupling guard includes a guard main body (110) formed so as to extend in a direction along an axis and having a tubular shape for circumferentially covering the shaft coupling. The guard main body includes a guard main body upper portion (120) and a guard main body lower portion (130) configured to be detachable from the guard main body upper portion. The shaft coupling guard further includes a leg portion (140, 150) formed integrally with the guard main body and configured to support the guard main body.

摘要： A cap acting as a grease retention feature and venting system allows crash optimization of a propeller shaft with a plunging constant velocity joint. The cap is located between a constant velocity joint and a tube of the propeller shaft system. The cap includes: a rim sealed against the inner diameter of the constant velocity joint, an interior vent chamber, a vent hole facing the interior components of the constant velocity joint and leading to the vent chamber, and an annular radial groove along the entire circumference connected to the vent chamber. The outer race has a hole perpendicular to the joint axis to complete venting to the atmosphere. In the event of a vehicle crash, the constant velocity internal joint components contact the device, causing the device to dislodge from its fixed position, contact the friction weld curls and fracture at a determined load.

摘要： A slip yoke assembly is provided. The slip yoke assembly includes a slip yoke having a long bore extending between a first end and a second end and a counterbore at the second end of the long bore. The counterbore has a first wall which defines a first diameter which is greater than a major diameter of the long bore. An annular groove is positioned between the long bore and the first diameter. A sealing member is disposed within the annular groove. The slip yoke assembly also includes a plug disposed within the counterbore and over the sealing member. The plug is secured to the slip yoke by a lip formed over the plug.
