The invention concerns a protective bellow for drive shaft articulated joint, consisting of a tapered bellow whereof the end with the small diameter (2) is expansible and has a saw-toothed section axially extended by folds (8) so as to enable the effortless radial extension of the bellow for fixing it above the 'bowl' of the articulated joint without using equipment of any kind; the central part can advantageously comprise one or several internal helical ribs (5) driving the grease contained in the device towards the articulation when the latter is rotating. Said bellow is designed to be placed around lubricated joints such as universal or constant velocity joints used for transmitting a rotating motion to mobile members, in particular in road motor vehicles and is of particular interest for the industrial sector manufacturing spare parts for repair shops and service centres for cars and heavy vehicles.

摘要:
An adaptor (18) is disclosed for connecting a generator (12) to a prime mover (10). The adaptor comprises two separable parts (30, 32). By providing an adaptor comprising two separable parts, it may be possible for one part to be removed in order to allow access to moving parts which would otherwise be inaccessible. This may simplify the process of servicing moving parts such as a coupling or bearings.

An air venting system for a constant velocity joint (20) having an inner race (24), an outer race (22), a cage (26), a plurality of torque transferring elements (28), a drive sleeve, a drive nut and a boot assembly. The outer race has a wall portion (90) having a vent hole (88, 242) with a first and a second axially extending channel (224, 264). A radially extending wall integrally connects the second axially extending channel to the first axially extending channel. A valve (256) having a stopper portion (264), a disk portion (258) and a breather portion (260) is at least partially located within the vent hole. The breather portion (260) further includes an axially extending ring (292) that terminates in a radially extending wall. At least a portion (300) of an edge portion of the radially extending wall of the breather portion of the valve is in direct contact with at least a portion (250) of an outer surface of the wall portion of the outer race.

A grease-retention assembly for a drive shaft assembly with a tubular shaft connected to a joint includes an outer race and a cap for grease retention and venting arranged in an inside diameter section of the outer race. The cap includes an outer annular rim with an annular indentation. The outer race includes a radial abutment shoulder extending radially inward and defining an axial end position of the rim of the cap, and a radial annular rib extending from the inside diameter section. The rib partially fills the annular indentation of the rim when the cap is in the axial end position. The cap further includes a central portion with a hollow air cavity extending across the cap between two radially extending walls, an axial hole through one of the two radially extending walls, and a radial annular groove communicating with the air cavity.

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.

It is an object of the present invention to provide a lubricating system that improves the force of retaining a lubricating component of a foam lubricant, minimizes an exudation amount of the lubricating component caused by deformation of the foam lubricant, is excellent in initial lubrication, has a long life, has a low cost, and is excellent in the productivity thereof; a bearing utilizing the lubricating system; a universal joint utilizing the lubricating system; and a process for the production thereof. A lubricating system includes a foam lubricant (9) containing a lubricating component in a resin thereof which foams, hardens, and becomes porous and a lubricant (10) for initial lubrication which is present together with the foam lubricant (9) in a portion to be lubricated. The lubricant (10) for initial lubrication consists of grease having a worked penetration not less than 300 or having a degree of oil separation not less than 0.7 wt% when the grease is left 24 hours at 70°C or consists of lubricating oil having a kinematic viscosity not less than 50mm 2 /second at 40°C. In initial lubrication of the lubricating system, the lubricant (10) for initial lubrication is essentially present at a sliding portion of the portion to be lubricated.
