Abstract:
An axial fixation of a splined shaft connection, particularly between a hub of a constant velocity joint and a shaft, whereby a splined end of the shaft is to be inserted in and extracted out of a splined bore of the hub from one side thereof. A snap ring is in contact with a stop surface of the shaft and a holding surface of groove in the hub. The snap ring and the holding surface are situated in the extraction direction axially behind the carrying zone of the splines, whereby the hub is provided with an opening following the holding surface having a radius which is greater than the radius of the radially-opposed portion of the shaft by an amount which is at least equal to the radial width of the snap ring.
Abstract:
A fixed constant velocity joint has a hollow outer part (1) whose inner face (2), relative to the longitudinal axis (4) of the outer part, is provided with outer running grooves (3). The cavity (5) of the outer part (1) contains an inner part (6) whose outer face (8) is provided with inner running grooves (7) which extend in meridian planes relative to the longitudinal axis (12) of the inner part and which are positioned opposite the outer running grooves (3). In each case, opposed inner running grooves (7) and outer running grooves (3), jointly, accommodate a ball (9) for torque transmitting purposes. The ball (9) is guided in a cage (11) arranged between the inner face (2) of the outer part (1) and the outer face (8) of the inner part (6). The cage (11), via its partial spherical face (18), is guided on an outer spherical face (14) of the inner part (6) facing away from the closed end (15) of the joint. The inner part (6) is provided with a first guiding face (30) which is designed as a hollow spherical zone, which, starting from the closed end (15), is designed to be undercut-free and whose center is positioned on the joint articulation center (13). Via a guiding element (22) with a second guiding face (29), designed as a spherical cap, the inner part (6) is axially secured as a result of the guiding element (22) resting against the supporting element (20). The guiding element (22) is displaceably supported on the supporting element (20) in the radial direction relative to the longitudinal axis (4) of the outer part.
Abstract:
A method of retaining a splined male member and a splined female member against relative axial motion therebetween when the splines of the members are in engagement with one another and a unitary axial retaining member for use in the practice of the method. The method includes the steps of mounting a hollow, thermoplastic axial retaining member to the interior surface of the female member and positively interconnecting the other end of the axial retaining member with the male member. The axial retaining member has an inwardly oriented flange for interconnecting one end of the retaining member to the male member and an outwardly oriented radial flange for interconnecting the opposite end of the retaining member to the female member. A plurality of longitudinal slots are optionally formed in one end of the retaining member to separate it into a plurality of flexible fingers to facilitate interconnection of that end of the retaining member with its associated male or female member. In one version of the axial retaining member, its radial thickness is substantially reduced along a longitudinal line that extends from the unslotted end thereof to one of the longitudinal slots, to facilitate the controlled separation of the axial retaining member along such longitudinal line when it is inserted over the male member, and in such version of the invention, some of the splines on the male member that engage the splines in the female member, are blocked to permit end loads on the joint using such members to be absorbed by the male and female members, without being imposed on the thermoplastic axial retaining member.
Abstract:
An axial retaining member for retaining a male member and a female member against relative axial motion therebetween. The axial retaining member includes a longitudinally extending main body having a longitudinal axis, a first end, a second end, and a central passageway therethrough for mounting the main body to the male member. Positive interconnection means, such as an inwardly oriented flange, are provided for interconnecting one end of the main body to the male member and a second interconnection means, such as an outwardly oriented radial flange, is provided for interconnecting the opposite end of the main body to the female member. A plurality of longitudinal slots are optionally formed in the main body to separate one end of the main body into a plurality of flexible fingers to facilitate interconnection of that end of the main body with its associated male or female member.
Abstract:
A constant velocity joint is provided with an outer part, in the inner surface of which tracks are provided, an inner part, on the outer surface of which corresponding tracks are provided, and with balls in a pivotable cage located in the space between the outer part and the inner part. Taking as a basis the particular axial displacement, caused by the torque, of the outer part and the inner part in relation to the cage, this displacement depending mainly on the amount of the respective axial clearances of the pairs of centering surfaces and/or on the brinelling of the window support surfaces by the balls in the running-in phase and also on the elastic flexibility of the parts, the running-in wear and the thermal expansion, the tracks of the outer part run in a mirror image with the corresponding tracks of the inner part in relation to the ball plane.
Abstract:
A constant velocity universal joint of the ball and groove type is provided with a double offset cage for locating the drive balls in the constant velocity plane. The cage has an interior bearing seat at one end only and an enlarged opening at the other end which facilitates the assembly of the joint by permitting the direct axial insertion of an inner drive member into the cage in the properly oriented position. The enlarged opening is closed by an end plate which cooperates with means carried by the inner drive member to maintain the inner drive member in bearing engagement with the cage. In one disclosed construction this means comprises an undersized ball carried in a cavity in the end of a shaft on which the inner drive member is mounted. In a second disclosed construction the means comprises a spring biased bearing shoe telescopingly carried by the shaft.
