  • Patent number: 10119562
    Abstract: An end fitting connector assembly includes an end fitting having a first end, a second end and a through opening that extends in a direction that is transverse to an end fitting axis extending through the first and second ends and in which the through opening is defined by a peripheral wall. An elastically deformable race fitted into the through opening of the end fitting includes an exterior surface that engages the peripheral wall and an interior surface configured to provide snap fitting engagement with a spherical ball mount. At least one feature retaining the race within the end fitting creates an increased disassembly force, which may prevent disassembly without employing a release tool or release feature. The interior and exterior surfaces of the race can include spherical surfaces for conforming to the spherical ball and the peripheral wall of the end fitting.

  • Patent number: 9863465
    Abstract: A method of manufacturing a slotted entry bearing assembly includes inserting an inner race into a central space of an outer race. The outer race is configured to receive the inner race through at least one slot. Once the inner race is fully inserted into the outer race, it is rotated approximately ninety degrees within the center space, effectively locking the inner race within the outer race. After the inner race is rotated ninety degrees, a molded seal is molded between the inner race and the at least one slot. The molded seal adheres to the at least one slot and is made of a polymeric material. The molding process used to mold the molded seal may be compression molding.

  • Patent number: 5924799
    Abstract: A segmented pilot ball is assembled within a spherical bearing for procesg a self lubricating liner. The two-part pilot ball includes a major annularly shaped hollow segment with a smaller cutout portion. A minor segment has the shape of the cutout portion so that when the major and minor segments are assembled, the minor segment complements the major segment to define the spherical outer shape of the pilot ball. An inner plug is shaped to fit within the assembled major and minor segments to provide a compressive force and interior support to the pilot ball within the outer race of the bearing. The bearing is formed by applying uncured liner material to the inner surface of the outer race either before or while rotating the outer race, to evenly distribute the liner and to increase the rate of drying. The outer race is then rotated while heating, in order to reduce liner flow and to form a uniform coating.

The assembly is composed of a journal box having a spheroidal cavity in which is socketed a ball-like bearing having an axial bore to accommodate the rudder shaft, the bearing being free to rotate within the cavity and thereby align itself with the rudder shaft as it deviates from the vertical as a result of forces imposed on the rudder. The ball-like bearing is formed by a cylindrical tube of UHMW polyethylene which is heated to an annealing temperature and thereby expanded to accept a fiber-reinforced resin sleeve which when the UHMW tube cools is compressed thereby. The resultant sleeve-lined tube is then machined to assume the ball-like shape of the bearing.

This aerostatic bearing comprises a bearing plate, which forms a bearing gap with the end of the shaft. An axial thrust, directed against the bearing, is exerted on the shaft. The bearing plate is provided with bore holes for releasing air into the bearing gap. An adjustable ball cup is arranged at the bearing plate for adjusting the bearing gap. This ball cup preferably takes the form of a sliding body which has a spherically shaped surface and is held in a corresponding spherically shaped bearing support. After the open-end spinning rotor has been adjustable cup adjusts automatically so that the surfaces which form the bearing gap are disposed parallel to one another.

  • Patent number: 5775815
    Abstract: A ball and socket swivel bearing is disclosed. The bearing comprises a rod end having a shank portion and a metallic socket portion. The socket portion has a continuous toroidal inner periphery and has outer walls defining circular side openings. A metallic swivel ball is mounted within the socket portion and is surrounded with a plastic bearing material. A key slot is provided in the shank portion and communicates with the space between the ball and the socket to act as a sprue for the introduction of plastic bearing material and to provide resistance to breakaway torque applied to the bearing material.

  • Patent number: 5772337
    Abstract: A bearing set for a ball and socket joint comprises an inner and outer bearing with a head of a ball stud engaging a spherical inner seat face of each of the bearings. An axial compression pre-load results when the bearing set and ball stud are inserted into a socket and the socket is closed. To prevent the over compression of the bearings and undesirable plastic deformation, a plurality of wedge shaped slots extend about each bearing between an outer axial surface and an outer peripheral surface. The slots provide material "flow" which eliminate unwanted plastic deformation by placing pre-load force and the natural material elasticity into a desired equilibrium. The tailored "cushioning" effect remains while still providing adequate compression pre-loading and dynamic stability to the ball stud.

  • Patent number: 5692840
    Abstract: A rugged spindle for a disk certifier that test the disks of a hard disk drive. The spindle contains a first bearing and a second bearing that are coupled together by a shaft. The first bearing is coupled to a chuck that captures a disk. The second bearing is coupled to the spindle shaft of an electric motor which rotates the disk. The bearings each contain an outer graphite sheath that is separated from a hardened housing by an air bearing. The connecting shaft is bonded to the first and second bearings by an adhesive that is injected through longitudinal passages of the shaft. The bonding adhesive flows along the interface of the connecting shaft and bearings until the adhesive fills an indicator slot of the shaft. Air bearings are created during the bonding process of the second bearing to insure an accurate relationship between the two bearings and the housing.

  • Patent number: 5680792
    Abstract: A drive bearing for a windscreen wiper system wherein two actuator rods for actuating two wiper arms are driven by a motor crank. The two bearings are concentrically nested one within the other thereby allowing the driving forces of the two rods to extend in one plane. Other features include the association of the individual bearing elements to the actuator elements, and the design of the bearing faces.

  • Patent number: 5676468
    Abstract: A bearing includes a first race in operational contact with a shaft, a second race in operational contact with the first race, and a third race in operational contact with the second race. The first, second and third races cooperate to define an aperture therethrough to the shaft. A connector is disposed through the aperture to functionally interlink the first race, the second race and the shaft to insure that the first race and the second race rotate substantially with the shaft. In operation, the first and second races define a first bearing surface that accommodates angular displacements of the shaft, and the second and third races define a second bearing surface that accommodates axial and rotational movements of the shaft.

  • Patent number: 5564853
    Abstract: A bearing set for a ball socket joint comprises an outer bearing and an inner bearing with a head of a ball stud engaging a spherical inner seat face of each of the bearings. A compression pre-load is applied when the inner bearing is inserted into a cavity of the outer bearing, a cylindrical outer wedge surface of the inner bearing having a greater diameter than a corresponding diameter of an inner skirt defining the cavity of the outer bearing. The bearing set is subjected to additional compression pre-load when the bearing set and ball stud are inserted into a socket and the socket is closed. The two-piece bearing set promotes easy Joint assembly, results in a joint that is extremely tight with no axial or radial play, but allows necessary ball stud rotation and oscillation, and compensates for wear by a self-adjusting feature whereby some of the compression pre-load is released as wear takes place.
