    Abstract: A bearing assembly includes a rotatable hub defining a load transfer surface. A porous bearing surrounds and is movable relative to the hub. The bearing includes bearing surfaces extending radially toward the hub. A grease is disposed between the porous bearing and the hub. The grease includes a grease base oil and functions as a lubricant between the hub and the bearing. The grease generally maintains separation between the transfer surface and the bearing surfaces while simultaneously removing debris from an area defined between one of the bearing surfaces and the transfer surface. A bearing base oil is impregnated in the porous bearing and is substantially similar to the grease base oil for replenishing the grease base oil as the grease base oil is depleted.

    Abstract: A needle bearing functioning as a rolling element comprises a uniform-diameter body part and bottom surfaces shaped in flat surfaces. A tapered reduced-diameter part and a chamfered part are interposed between the body part and the bottom surface. A gentle reduction in diameter is first made by the tapered reduced-diameter part, and then a relatively sharp reduction in diameter is made by the chamfered part. Consequently, in the needle bearings adjacent to each other, their tapered reduced-diameter parts are separated from each other.

In addition, a method is provided for taking up a clearance between one or more first rollers and a bearing race in which the rollers are positioned. At least one resiliently compressible second roller is provided rollably secured within the bearing. The compressible second roller has an outer diameter greater than an outer diameter of any of the first rollers, such that the compressible second roller resiliently compresses when the bearing is positioned in the bearing race. Forces generated by compression of the resiliently compressible second roller urge the first rollers against a surface of the bearing race, thereby taking up the clearance between the first rollers and the race.

  • Patent number: 7178984
    Abstract: A bearing arrangement for supporting a universal joint trunnion in an outer cup includes a radial bearing having cylindrical rolling elements disposed between the trunnion and the outer cup, and a resistance member made of a material to allow elastic deformation and bearing upon a confronting surface area of an end surface of the trunnion. The resistance member and the trunnion are hereby so configured either alone or in combination as to form a large lubricant reservoir. Disposed at a distance to the end surface of the trunnion is a stop member to define an axial gap, whereby the stop member inhibits an axial movement of the trunnion after the trunnion has moved in axial direction to close the gap.

  • Patent number: 7160192
    Abstract: Across shaft has four trunnions externally provided with roller bearings in a plurality of rows. Each of the trunnions is formed with a recess at its distal end face. A bottom region of the recess is formed in a spherical shape. An inner diameter of an opening region of the recess except the bottom region in a spherical shape is set to be gradually larger toward an opening end edge of the recess. A depth of the recess from the opening end edge to the deepest point is set to be 30 to 70% of the total length of the rollers in an axial direction. By providing this recess is a shape of a punch bowl, rigidity of each of the trunnions of the cross shaft can be reduced, while securing sufficient strength of the trunnion.

  • Patent number: 6991545
    Abstract: A bearing assembly for a bearing journal (13), especially of a cross member of a universal joint, has a bearing journal (13) with a cylindrical outer face (14), an end face (16) and a journal axis (15). A bearing element (8) has a cylindrical bearing bore (9) with a bottom face (11) and a running face (10) which is arranged at a radial distance from the outer face (14) of the bearing journal (13). Rolling-contact members (17), at their respective ends, include at least partially planar first end face (18) and second end face (19). The faces (18) and (19) are arranged between the running face (10) and the outer face (14). A stop face (20) includes an annular contact face (21) for the first end face (18) of the rolling-contact members (17). A pressure disk (22) is included with a disk portion (23) arranged between the end face (16) of the bearing journal (13) and the bottom face (11).
