    摘要： A slinger has a substantially L-shaped cross-section and includes a rotating cylindrical portion and a rotating circular ring portion. An inner circumferential surface of the rotating cylindrical portion is a stepped cylindrical surface in which a large-diameter portion formed at a portion close to the rotating circular ring portion and a small-diameter portion formed in the remainder are continuously connected by a stepped portion. The encoder supported by the rotating circular ring portion is formed by solidifying and securing a molten permanent magnet material in a state that a molding die collides with the stepped portion. An outer diameter of a hub is defined as φD, an inner diameter of the small-diameter portion in a free state is defined as φd1, and an inner diameter of the encoder in a free state is defined as φd2, a relationship of φd1≦φd2

    摘要： A rotary shaft and a seal mechanism are provided. The rotary shaft extends into outside air outside a case via a shaft hole provided in the case of a drive system. The seal mechanism prevents entry of foreign matter from the outside air into the shaft hole. The case includes a canopy portion and a recessed portion. The recessed portion is recessed coaxially with the canopy portion from an end face of the canopy portion in the direction of the axis. The seal mechanism includes a deflector and a seal member. The deflector is fixed to the rotary shaft in a liquid-tight manner, and extends into the recessed portion. The seal member is an elastic body. The seal member is fixed in the shaft hole in a liquid-tight manner, and is in sliding contact in a liquid-tight manner with the rotary shaft and the deflector.

    摘要： A seal assembly is for sealing a space between first and second members, the first member having a central axis and an outer circumferential surface extending about the axis, the second member having a radially-extending axial surface. The seal assembly includes a generally annular elastomeric seal body disposed about the first member outer surface and extending circumferentially about the central axis, the body including a base portion and a sealing portion having an inner end integrally formed with the base portion and an outer, free end sealingly engageable with the second member axial surface, a generally annular cavity being defined between the base portion and the sealing portion. A biasing member is disposed within the annular cavity and is configured to exert a generally radially-inwardly directed force on the seal body so as to substantially prevent relative angular displacement between the seal body and the first member.

    摘要： A seal assembly can be incorporated into a track joint assembly of an undercarriage of a track-type machine. The track joint can have a first member pivotable about a rotational axis relative to a second member thereof. The first member includes a seal member engagement surface defining, at least in part, an axially-extending seal cavity about the rotational axis and within which the seal assembly is disposed. The seal assembly can include a thrust ring and a seal member mounted to the thrust ring. The seal member includes a first member engagement surface, a second member engagement surface, a frusto-conical inner relief surface, a thrust ring engagement surface, and an outer relief surface.
