  • Patent number: 8127639
    Abstract: A telescopically collapsible vehicular steering column assembly includes inner and outer shaft tubes which are joined in a sliding fit by a bushing. The bushing includes a pair of spaced journal bearings formed of steel-backed PTFE held in a plastic carrier body. The bushing is located in a receiving chamber in the outer shaft tube. A clearance compensator reacts against the receiving chamber to exert a radial compressive force through the carrier body and the journal bearings to improve the sliding fit with the inner shaft tube and remove lash. The clearance compensator can take any form, such as a hollow annular rib, a skirt with a flexible free end, or an array of nubs carried in thinned sections of the carrier body. The clearance compensator in all of these variations operates within a clearance space and has dimensional attributes which can be changed during the design and manufacturing phases of the bushing to optimize a characteristic of the steering column assembly.

    Abstract: A self-aligning dynamic hinge sleeve for attachment to a pitch hinge in a position that places the hinge sleeve in contact with a pitch bearing. The hinge sleeve is comprised of an inner race, a middle race and an outer race, wherein the middle race is an elastomeric material, or another soft material, that bonds the inner and outer races together and allows the inner race and outer race to rotate with respect to each other. As the pitch hinge transmits forces and moment to a pitch shaft, the dynamic hinge sleeve aligns with a pitch bearing secured onto the pitch shaft. This results in a self-aligning pitch bearing rotor that significantly reduces the level of peak that loads upon a bearing and thereby permits the use of self-lubricating bearings in a rotor.

  • Patent number: 5961219
    Abstract: A split taper bushing assembly includes a bearing member, an inner sleeve received in a hollow center defined by the bearing and an optional outer sleeve which receives the bearing member in an open center defined therein. The bearing member also includes a tapered skirt. The skirt includes a slit which permits the bearing member to contract during assembly to account for variances in its dimensional tolerances, thus ensuring a proper fit between the bearing member and any mating part. The bearing member is formed using a polyurethane type material. Since such a material resists deterioration due to contact with lubricants commonly used in the automotive industry, the bushing assembly can be relubricated during operation without any destructive affect on the bearing member.

  • Patent number: 5820115
    Abstract: A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.

  • Patent number: 5678930
    Abstract: A bearing assembly has first and second trunnions supporting a bearing and defining a trunnion pivot axis. In the improvement, each of the trunnions is mounted in and supported by a separate cushion member of annular shape. The assembly permits bearing pivoting about the trunnion pivot axis (i.e., about the X axis) and the cushion members permit limited freedom of movement of the trunnions in axes (i.e., the Y and/or Z axes) which are angular to the pivot axis. The new bearing assembly is ideal for use on an earth-working implement such as a disc harrow.

  • Patent number: 5593233
    Abstract: The present invention pertains to a radially and axially elastic slide bush bearing for chassis parts in motor vehicles with thrust bearings between an inner pipe (1) and an outer bush (2) and with an elastomer body (4) surrounding the outer bush (2). To obtain a one-part design, a thrust bearing transmitting axial forces, consisting of a disk (8 and 9) and an abutment (10 and 11), is provided with a sealing lip (12 and 13) surrounding this thrust bearing at both axial bearing ends, wherein the thrust bearing has a smaller diameter compared with the diameter of the bearing eye in the chassis part (5) at one bearing end in the external diameter of the sealing lip (13) axially surrounding the thrust bearing.
