摘要： A wheel bearing assembly is provided which has a rotating speed sensor unit which includes a seal for preventing entry of foreign matter and which takes up little space and thus can be mounted on the wheel bearing assembly without increasing the axial dimension of the fixed member of the wheel bearing assembly. The assembly includes a fixed member fixed to a vehicle body, and a rotary member rotatably supported in the stationary member through a bearing and mounted to a vehicle wheel. An annular sensor is fitted to a knuckle, which is a part of the fixed member, on the inboard side of the bearing. A sensor seal is fitted to the annular sensor and has a seal lip kept in slide contact with a seal land formed on a constant-velocity joint outer ring, which is a part of the rotary member, to define a sealed space on the inboard side of the bearing. An encoder is mounted on a bearing inner ring, which is a part of the rotary member, in the sealed space. The sensor element is disposed in the sealed space, opposite the encoder.

摘要： A wheel bearing includes a sealing device 5 positioned between inner and outer members 1 and 2. This sealing device 5 includes an elastic member 14, which eventually forms an encoder grid and is provided on a first annular sealing plate 11. A second annular sealing plate 12 is provided with sealing lips 16a to 16c. An engagement 18 between a cylindrical wall 11a of the first annular sealing plate 11 and the inner member 1 is provided with an elastic member 20 made of a material dissimilar to that for the elastic material 14. This elastic member 20 may be a rubber coated layer, resin paint layer, a thin film of adhesive material or a ring-shaped rubber member. Thereby, any possible ingress of water across an engagement surface of the annular sealing plate is prevented, accompanied by increase of the lifetime of the bearing, with no problem associated with separation and displacement of the annular sealing plates. The magnetic flux density can also be easily secured.

摘要： The present invention provides a mechanical seal preventing the deformation of the cartilage and exhibiting a good sealing performance. In said mechanical seal, the deformation of the back portion of the cartilage due to the force from the pump housing is absorbed by forming a groove portion having cross section substantially a triangular shape at the back portion of the cartilage. As a result, the deformation hardly transfers to the area near the inner tube portion of the cartilage 16 and the inner tube portion of the back portion; and the relative position of the seal ring, and the bellows or so scarcely changes with respect to the structure of the mating ring or so on the side of the rotation axis, thus the assembling length and the assembled load of the mechanical seal does not change, which allows the mechanical seal to exhibit good sealing performance.

摘要： The present invention provides a mechanical seal preventing the deformation of the cartilage and exhibiting a good sealing performance. In said mechanical seal, the deformation of the back portion 16d of the cartilage due to the force from the pump housing 3 is absorbed by forming a groove portion 16f having cross section substantially a triangular shape at the back portion 16d of the cartilage 16. As a result, the deformation hardly transfers to the area near the inner tube portion 16a of the cartilage 16 and the inner tube portion 16a of the back portion 16d; and the relative position of the seal ring 14, and the bellows 15 or so scarcely changes with respect to the structure of the mating ring 11 or so on the side of the rotation axis 2, thus the assembling length and the assembled load of the mechanical seal 9 does not change, which allows the mechanical seal 9 to exhibit good sealing performance.

摘要： In a conductive rolling bearing comprising an inner ring (11), an outer ring (12), a plurality of rolling elements (13) mounted between the inner ring and the outer ring, and seal members for sealing the space between the inner ring and the outer ring, the seal members have one end thereof secured to one of the inner ring and the outer ring and the other end thereof in an elastic, sliding contact with a seal wall surface (18) formed on the other. The free end (19) of the seal member (15) is bent outwardly of the bearing and the seal member (15) is in a sliding contact with the seal wall surface (18) on its bent portion (20). This arrangement gives the effects of providing a low, stable torque for the bearing and of improving the seal performance of the bearing. This conductive rolling bearing is used in a steering assembly of an automobile and bearing assemblies having a bearing near electrical devices.
