    Abstract: A mounting device in the form of a substantially annular washer allows a bearing having relatively movable bearing rings to be blind mounted in a bearing seat in a housing or on a shaft. The washer is fitted to one of the bearing rings and abuts a side face of the other bearing ring to transfer an axial mounting force between the two bearing rings to mount one of the bearing rings in the bearing seat. The washer is tapering and assumes a first stable position to transfer axial force sufficient to push one of the bearing rings into its seat and an unstable region encountered after the one bearing ring has reached its mounted position. Under continued axial force, the washer flexes away from the side face of the other bearing ring to an inverted tapering, second stable position, with a passage between the bearing rings being opened.

  • Patent number: 6145199
    Abstract: A bearing system for mounting a rotating shaft includes a bearing assembly and a bearing mounting structure. The bearing assembly has an inner race which contacts the rotating shaft, an outer race, and bearing elements positioned therebetween. The outer race has an exterior surface with an outer dimension. The bearing mounting structure has a region for affixing it to an external structure in which the bearing system is to function. An internal surface of the bearing mounting structure defines a bearing cavity in which the bearing assembly is to be disposed. The internal surface engages the exterior surface of the outer race. The retention force exerted by the internal surface on the outer surface is determined by the design of the inner surface of the bearing mounting structure that defines the bearing cavity. The internal surface has cut-outs, or scallops, extending axially (with respect to the shaft) along the internal surface.

  • Patent number: 6112411
    Abstract: There is disclosed a method of mounting a wheel hub bearing assembly to the knuckle (10) of a vehicle suspension standard by forcefully inserting the outer race (20) of the bearing in a bore (11) in the knuckle (10). The bore has a groove (15) near its axially outer side to accommodate a snap ring (14) for axially securing the bearing's outer race (20) within the bore (11). Angularly spaced radial slots (24) are provided in the axially outer rim of the knuckle (10); a hub bearing unit is assembled separately. The snap ring (14, 14') is fitted over the hub at an axial location between the axially outer end portion (23) of the bearing outer race (20) and a portion (34) of the hub (16) facing said end portion (23); at least one axially tapered sliding surface (33, 34, 23) is provided between said facing portions (23, 34).

  • Patent number: 6089758
    Abstract: A molded polymeric bearing housing is formed of a moldable polymer base material in combination with a glass fiber reinforcing component. A foaming agent is added to the base material to create a fine structural foam within interior regions of the housing. A density gradient is established between regions adjacent to the surfaces of the housing and the internal regions, thereby reducing the need for reinforcing ribs particularly in a base or mounting portion of the housing. An antimicrobial agent may be added to the housing material to inhibit the growth and proliferation of fungi, molds, bacteria, and so forth. Structural features of the housing may be formed subsequent to the molding process, such as by turning operations. Metal inserts may be provided to avoid crushing of regions of the housing, such as by attachment fasteners. The housing forms a mounting base surface in a single plane coextensive with the footprint of the housing.

  • Patent number: 5975766
    Abstract: A shaft (12) rotatively mounted in a support (14) by rolling elements comprising at least one first rolling bearing (18) providing an oblique contact surface axially biased in one direction by an elastic return force and in a direction opposed to the preceding direction by a thrust block (28) carried by the shaft (12). The block (28) is axially movable between a first position and a second position of application of a force opposed to the return force. The magnitude of the opposing force is greater in the second position of the block (28) than in the first position of this block (28). The block (28) is connected to the shaft by a connection (32) which is cooperative by the effect of friction with the shaft (12).

  • Patent number: 5971621
    Abstract: An apparatus for axially retaining a shaft comprises a shaft having an axis of rotation and an axially-affixed member having a bore therethrough coaxial with the shaft and having an inside diameter, the shaft passing through the bore. The apparatus also includes a retainer mounted about the shaft in a first groove, the retainer having an outside diameter larger than the diameter of the bore. The apparatus further comprises a retaining ring mounted about the shaft in a second groove, the retaining ring having a compressed outside diameter less than the inside diameter of the bore and an uncompressed outside diameter larger than the diameter of the bore. The first groove and the second groove are located on first and second axial sides of the member, respectively, and the retainer and the retaining ring cooperate to substantially prevent axial movement of the shaft with respect to the member. A method for assembling an apparatus having a shaft comprises placing a retaining ring about the shaft in a groove.
