Patent number: 5947612Abstract: A rotating machine comprises a housing defining a generally cylindrical bearing pocket and defining an interior and exterior. The machine also includes a bearing retainer having a generally cylindrical sleeve portion retained in the bearing pocket and a bearing having an outer race and an inner race, the outer race affixed within the cylindrical sleeve portion. The machine further has a rotating member mounted on a shaft for rotation therewith, the shaft having a portion affixed within the inner race of the bearing. In one embodiment, the bearing retainer includes anti-rotation keying projections the bearing pocket includes complementary depressions for the keying projections. The keying projections cooperate with the complementary depressions to prevent rotation of the bearing retainer with respect to the bearing pocket. In another embodiment, a cap is affixed to the bearing retainer to substantially prevent contamination from reaching the bearing from the exterior.Type: GrantFiled: March 2, 1998Date of Patent: September 7, 1999Assignee: Ford Motor CompanyInventors: David Frank Dennison Buck, Kevin Roy Harpenau, Brian Scott Phillips, Steven John Yockey

Patent number: 5857781Abstract: A bearing apparatus is provided including an improved end cover. The end cover has a cup element for receipt over the end of a shaft supported by the bearing apparatus. An arm element extends from the cup element and may define a slot for receipt of a suitable threaded member, such as the bearing's lubricant fitting. When the lubricant fitting is tightened, the end cover will be maintained in the desired position on the bearing housing.Type: GrantFiled: September 5, 1996Date of Patent: January 12, 1999Assignee: Reliance Electric Industrial CompanyInventors: Robert E. Ward, Howard M. Martinie

Patent number: 5833372Abstract: An auxiliary seal for a bearing includes a seal housing supported by the bearing housing, and a seal ring interference fitting around a mechanical element such as a shaft or sleeve supported for rotation by the bearing. The housing and sleeve include a series of rings that interface with one another to maintain the seal ring in place on the mechanical element. A face rubbing seal is supported on the seal ring and contacts a portion of the seal housing as the mechanical element rotates relative to the bearing housing. The seal ring has an integral backup portion which contacts the face rubbing seal to prevent the face rubbing seal from sliding axially away from the seal housing. A series of seal barriers are defined by the seal housing and seal ring, including contact seals, grease dams and labyrinth seals.Type: GrantFiled: June 2, 1997Date of Patent: November 10, 1998Assignee: Reliance Electric Industrial CompanyInventor: Donald L. Nisley

Patent number: 5816711Abstract: A package bearing includes two cones that fit over a spindle on a wheel hub, a double cup that surrounds the cones and is configured to bolt against the suspension system of a vehicle, and tapered rollers that are located between opposed raceways on the cup and the two cones. The cup at each of its ends has an end bore. The end bore at the outboard end contains a seal which establishes a dynamic fluid barrier with the outboard cone. The end bore at the inboard end contains a flexible retainer that creates a closure between the cup and the inboard cone. The end bore at the outboard end also receives an end cap which extends across the end of the inboard cup and the end of the spindle to close the entire inboard end of the bearing. The seal and retainer unitize the bearing for shipping and handling. The retainer further keeps grease from migrating into the end cap during the operation of the bearing.Type: GrantFiled: September 26, 1997Date of Patent: October 6, 1998Assignee: The Timken CompanyInventor: John R. Gingrich

Patent number: 5711616Abstract: A bearing seal (10) has a casing 11 with a dynamic sealing element (18) such as an EHD at an inner edge. At the outer edge of the casing (11) a static sealing element (14) is provided on an axially extending flange (13). The static sealing element (14) includes opposing outwardly projecting sealing lips (23) which are capable of deflection and which have an outer diameter greater than the diameter of the bearing housing bore when unrestrained. The bearing seal (10) seals the inner and outer race rings of a bearing dynamically and also the outer race ring with the bearing housing statically and positively.Type: GrantFiled: April 9, 1996Date of Patent: January 27, 1998Assignee: The Timken CompanyInventors: Roland Gassmann, Graham Sturman, Roland Duval

Patent number: 5711617Abstract: A dustcap (10) for a bearing assembly (12) includes a sidewall (50) having a first end (52) and a second end (54). An endwall (56) extends from the second end (54) of the sidewall (50) to form a cup. A lip (60) extends radially outward from the first end (52) of the sidewall (50). The lip (60) has a first angled portion (62) and a second angled portion (64) connected to form a circumferential apex (66). The bearing assembly (12) has an outer race ring (20) that cooperates with an inner race ring (22) to form a raceway (26) in which a plurality of balls (24) are disposed. The outer race ring (20) has a seal groove (40A) disposed therein which is configured to accept the apex (64) of the lip (60) of the dustcap (10) in a snap fit. By connecting the dustcap (10) to the outer race ring (20) of the bearing assembly (12), the dustcap (10) remains aligned with the bearing assembly (12) when the bearing assembly (12) becomes misaligned.Type: GrantFiled: August 15, 1996Date of Patent: January 27, 1998Assignee: MB Manufacturing, Inc.Inventor: Horst H. Scheller

Patent number: 5711618Abstract: A rolling element bearing is mounted in the bore of a housing, and a hollow end cap is mounted over the bearing. Circumferentially spaced grooves in the bore extend axially partially through the housing from one axial end to facilitate insertion of the bearing. The end cap has a closed wall at one axial end and resilient projections extending axially from its open end, firmly engaging the housing grooves. A strap holder, integral with the end cap, may be provided between the two resilient projections, extending radially outwardly along the axial end of the housing and axially along the housing outer surface and has an opening for mounting a grease fitting. An integral flexible strap extends from the strap holder and has a cover to enclose the grease fitting.Type: GrantFiled: November 27, 1996Date of Patent: January 27, 1998Assignee: The Torrington CompanyInventor: Walter P. Waskiewicz

Patent number: 5711393Abstract: A drive axle assembly has a gear housing, axle tubes extending outwardly of the gear housing, and an axle shaft disposed in each axle tube with an external wheel hub at a protruding end of the axle shaft. Each axle shaft is rotatably supported in a flanged end collar at a remote end of the axle tube by a bearing assembly that is mounted on the axle shaft and retained in the end collar by a screw cap. The drive axle assembly includes a brake member mounted externally on the end collar in juxtaposition to an external shaped flange of the end collar. The screw cap clamps the brake member against the external flange to locate the brake member on the axle tube in an axial direction and to nonrotatably couple the brake member to the axle tube.Type: GrantFiled: July 20, 1995Date of Patent: January 27, 1998Assignee: American Axle & Manufacturing Inc.Inventor: Garrett W. Gage
