    摘要: A chain guide having excellent durability is provided. The chain guide includes a guide base arranged along a portion of an outer periphery of a chain for transmitting torque and elongated in the direction in which the chain travels; a plurality of roller shafts attached to the guide base so as to be spaced apart from each other along the direction in which the chain travels; and rollers rotatably supported by the respective roller shafts. The distance between the centers of each adjacent pair of the rollers is set to be shorter in the area where a larger load is applied to the rollers.

    摘要: A chain guide includes a plurality of roller shafts provided on one side of a timing chain for torque transmission and spaced from each other in the longitudinal direction of a guide base facing the timing chain. The respective roller shafts rotatably support chain guiding rollers in the form of needle roller bearings. The rollers are cylindrical members having the same diameter over the entire axial direction such that the rollers are movable in the axial direction relative to the timing chain. The rollers are supported so as to be movable in the axial direction. When the rollers and the timing chain move relative to each other in the axial direction and the rollers move relative to the roller shafts in the axial direction, contact portions between the rollers and the roller shafts are displaced in the axial direction, so that radial loads are not locally applied.

    摘要: An outer ring for rocking bearing (11a) includes a raceway surface (12a) on the inner diameter side and has flange parts (13a) and (13b) provided by bending both axial ends to the inner diameter side. The flange parts (13a) and (13b) are provided with bent parts (17a) and (17b) axially bent toward the raceway surface (12a) side so as to enfold a retainer arranged on the inner diameter side. Thus, the retainer can be enfolded by the bent parts (17a) and (17b). Therefore, even when the retainer comes to be moved to the inner diameter side of the outer ring for rocking bearing (11a), the retainer is caught by the bent parts (17a) and (17b), so that the movement of the retainer to the inner diameter side is restricted and rollers and the retainer can be prevented from dropping off.

    摘要: [Object] To prolong the life of a shell type needle roller bearing used e.g. for a support structure for a compressor spindle or for a support structure for a piston pump driving portion, and to lower the acoustic level during use. [Means for solution] A shell type outer ring 2 of a shell type needle roller bearing 1 is formed by a pressing combined with an ironing step, and the lubricating conditions in this ironing step on the outer-diameter ironed surface, which becomes the outer-diameter surface of the outer ring 2, are in a substantially fluid lubricating state so as to restrict the circumferential surface roughness of the inner-diameter surface, the inner-diameter roundness, and the amount of uneven thickness of the tubular portion to predetermined value ranges, thereby prolonging the life of the shell type needle roller bearing and lowering the acoustic level during use.

    摘要: A retainer comprises a roller retaining click which is bent from an inner diameter edge of a rib portion toward the inside in an axial direction and extends so as to protrude and positioned between adjacent rollers. A part of the retainer other than the roller retaining click is hardened by high-frequency quenching and high-frequency tempering.

    摘要: Two or more arcuate members (2A, 2B), each having a plurality of pockets (3) defined therein for accommodating corresponding rollers, are placed one above the other to form a ring shaped assembly and are subsequently connected non-separably together by means of a retention ring (4) to thereby complete the cage (1). The arcuate members (2A, 2B) are so connected together that its inner periphery may assume a position radially inwardly of the outer diameter of a shaft such that in a condition having been assembled onto the shaft, they can displace in a direction radially outwardly against an elastic compressive force of the retention ring (4) to invite a circumferential gap (S) at each joint between the arcuate members (2A, 2B).
