  • Patent number: 7686313
    Abstract: A speed sensor for a wheel end that has an interior that is substantially isolated from an atmosphere around the wheel end. The speed sensor is carried by a housing of the wheel end for monitoring the rotation of the wheel end and indicating the angular velocity of the wheel end. The speed sensor includes a cable leading from the sensor to a location remote from the wheel end and further includes leads that transmit a signal and a sheath that encloses the leads. The sheath is open enough to allow a fluid to flow through its interior. A vent channel provides communication between the interior of the wheel end and the interior of the sheath on the cable.

  • Publication number: 20090080824
    Abstract: A roller bearing for use in transmission cases (1) made from aluminum alloy or other lightweight materials where the transmission contains a steel shaft (2) which is supported in the case on two directly mounted tapered roller bearings (8,9) so that the two bearings (8,9) confine the shaft (2) both radially and axially. To compensate for the differences in expansion and contraction between the case and the steel shaft (2) as the transmission or transaxle experiences variations in temperature, a race (20) of at least one of the bearings is fitted with a compensating ring (34) having a coefficient of thermal expansion greater than that of the case (1) or shaft (2). As a consequence, the bearings operate at a generally uniform setting over a wide range of temperature variations.

  • Patent number: 5009523
    Abstract: A bearing assembly for supporting a shaft in a housing includes two single row tapered roller bearings mounted in axial alignment, yet in opposition. The first bearing is conventional, having the usual cup, cone and complement of tapered rollers. The second bearing has a conventional cone and complement of rollers which may be the same as their counterparts in the first bearing. However, the cup of the second bearing further has an integral axial extension which projects toward and abuts the back face of the cup for the first bearing. The two cones are separated by a spacer and are clamped between two radial abutments on the shaft, whereas the cup of the second bearing is clamped with respect to the housing such that it is incapable of shifting relative to the housing. This secures the entire bearing assembly in the housing.

  • Patent number: 4428630
    Abstract: A bearing having an outer race provided with end bores, inner races provided with wear surfaces located within the end bores, and rolling elements arranged in two rows between the races, is closed at its ends by seals which prevent excessive pressure from developing within the bearing during operation or relubrication. Each seal includes a metal case having an axial wall and pair of spaced apart radial walls. The axial wall is pressed into one of the end bores of the outer race, whereas the radial walls form a chamber that communicates with the interior of the bearing through apertures in the inner radial wall.
