    摘要: A tapered roller bearing for an automobile transmission is provided, which is capable of preventing very early occurrence of surface originating flaking even when loss in pre-load has occurred under severe lubricating conditions. The tapered roller bearing is constructed such that the maximum contact pressure on a raceway surface is kept less than 3000 MPa under a condition where loss in pre-load has occurred.

    摘要: An object is to exert the intended fretting-preventive effect without being influenced by the size of variation in rotation (variation in speed) or the size of vibration. An arrangement comprising a main shaft gear 1 having a raceway surface 1c on its inner peripheral surface, a bearing inner ring 2 having a raceway surface 2a on the outer periphery, tapered rollers 3 disposed between the raceway surface 1c of the main shaft gear 1 and the raceway surface 2a of the bearing inner ring 2 and held at predetermined circumferential intervals by a cage 4, an imbalance means which produces a circumferential weight imbalance in the assembly of the tapered rollers 3 and cage 4, wherein the roughness of the cone back face 2b of the bearing inner ring 2 is 0.01-0.04 &mgr;mRa, and the roughness of the large end faces 3b of the tapered rollers 3 is 0.01-0.05 &mgr;mRa, and the radius of the large end faces 3b are worked such that the maximum value thereof including the working precision is substantially equal to the reference radius. Further, full crowning is applied to the rolling contact surfaces 3a of the tapered rollers 3 and the surfaces of the tapered rollers 3 are formed with coating films of the MoS2 type.

    摘要: A wheel support device which is easy to assemble and compact in size. A pair of tapered roller bearings are mounted on the outer periphery of an axle. The pair of tapered roller bearings rotatably support an axle hub that rotates together with a wheel. A seal assembly is mounted between the outer and inner rings of one of the tapered roller bearings. The seal assembly prevents leakage of grease sealed in the axle hub and entry of muddy water from outside, and makes it unnecessary to provide a separate seal member, thus making it possible to assemble the wheel support device easily and to reduce its size.

    摘要: A sealed rolling bearing includes an inner ring and an outer ring defining a bearing space therebetween. Axially inner and outer contact seals are provided on each side of the bearing space to seal the bearing space. The axially outer contact seals stop any splashed muddy water, thereby keeping the lips of the axially inner contact seals and their sliding contact surfaces free of muddy water. This prevents the lips of the axially inner contact seals and their sliding contact surfaces from becoming worn by muddy water. The axially inner contact seals thus maintain high sealability even if the bearing is used in environments where muddy water splashes.
