  • Patent number: 10612625
    Abstract: A planet wheel assembly includes a planet shaft, a planet wheel having radial contact surfaces and axial contact surfaces, bushings connected to the planet shaft, radial sliding elements between radial contact surfaces of the bushings and the radial contact surfaces of the planet wheel, and axial sliding elements between axial contact surfaces of the bushings and the axial contact surfaces of the planet wheel. The planet wheel is shaped to constitute a circumferential projection which protrudes radially towards the planet shaft, is axially between the radial sliding elements, and forms the first and second axial contact surfaces of the planet wheel. This arrangement, where the radial sliding elements are axially outmost and the axial sliding elements are on the middle, improves the ability of the radial sliding elements to act against forces tilting the planet wheel.

  • Patent number: 10052248
    Abstract: An adjustable wheelchair headrest system to provide wheelchair users with the ability to control their headrest without assistance form another individual. Some wheelchair users are unable to adjust their headrests without assistance, and as a result, have no control over their head and neck positioning throughout the day. The system provides wheelchair users with a multi-directional adjustable headrest that may be controlled through a mobile device. The system includes a universal mounting system and manually adjustable starting positions for each linear translation and rotational assembly, which allows the system to easily mount to any existing wheelchair. The system enables users to adjust their headrest to suit any situation (driving, watching a movie, eating, etc.). Wheelchair reliant individuals can now enjoy day-to-day comfort, control their own upper body posture, and perform additional tasks without assistance.

  • Patent number: 9356487
    Abstract: A bearing assembly for a rotating shaft uses a carbide sleeve to prevent wear and carry load. The carbide sleeves provide increased life for rotating components used in the severe environments in the oil and gas industries. Various mechanisms can couple the carbide sleeve to the rotating shaft, including keys, keyways, drive rings, reaction rings, and other members to provide particular benefits. These mechanisms allow the carbide sleeve to bear the compressive load of other components, for example, or to slide axially on the shaft, when needed.

    Abstract: Particles, embedded into a sliding layer, have a coating, within which a lubricant, e.g., a liquid, is contained. A component with the sliding layer provides a sliding surface that can be used as a backup bearing to ensure emergency operating properties, for example, of a shaft that is mounted in a main bearing. When the shaft strikes the bearing surface, the coating of the particles that are exposed on the bearing surface are destroyed and the lubricant can exit. Advantageously, the sliding properties of the sliding surface are thereby improved.

To this end, the method is so conceived that an inner surface of the mounting hole of the component and/or a circumferential surface of the shaft is/are partially fused so that calotte-shaped projections protruding beyond the inner surface of the mounting hole and/or the circumferential surface of the shaft will form, that the component and/or the shaft is/are subsequently cooled, so that the calotte-shaped projections will solidify, and that the component is then slipped onto the shaft until the mounting hole is positioned in a fastening area of the shaft. In addition, the present invention also relates to components for establishing a press fit of a shaft-hub connection.

  • Patent number: 8205515
    Abstract: A bushing for use in a hollow tube housing of a rack and pinion steering system. The bushing is formed as a generally cylindrical body having a central aperture and a circular cantilevered flange that extends outward from the body of the bushing. The flange contains a leading surface for compression contact with a corresponding interfering surface on the hollow interior of the rack housing. The flange is disposed to continuously compress a portion of its leading surface against a portion of the interfering surface on the hollow interior of the housing over a predetermined range of temperatures when the bushing is installed in the housing, and thereby providing thermal compensation to maintain a seal.
