摘要： A buried plug has interference which is made to exert a load or stress less in a widthwise direction of the guide rail than in a lengthwise direction of the guide rail, thereby protect raceways on the guide rail against any deformation such as bulge. The buried plug has a mating zone to press fit into a counterbore of a bolt hole and a leading zone to guide the mating zone into the counterbore. Let assuming a definition that a direction perpendicular to a lengthwise direction of the guide rail is referred to a direction opposed to the raceway surface or the widthwise direction of the guide rail, the interference exerting a force on the counterbore in the widthwise direction is determined less than the interference exerting the force on the counterbore in the lengthwise direction of the guide rail.

摘要： Construction of a thrust roller bearing with races is achieved in which a function of preventing a cage 3, first thrust race 4a and second thrust race 5a from separating from each other can be maintained, the amount of eccentricity that is allowed between a pair of members that rotate relative to each other can be increased, and the amount of lubricant that can flow inside the bearing can be increased. The outer diameter of the outer-diameter side flange 8a that is formed around the outer circumferential edge section of the first thrust race 4a is 60 mm to 120 mm, the inner diameter of the inner-diameter side flange 11a that is formed around the inner-circumferential edge section of the inner-diameter side flange 5a is 40 mm to 80 mm, and the internal gap is 1 mm to 2 mm. Therefore, outer-diameter side locking sections 9a are intermittently formed in the circumferential direction on the tip-end edge of the outer-diameter side flange 8a.

摘要： In a copper-based sliding material in which a Cu alloy layer contains 5% to 30% by mass of Bi, and the balance consisting of Cu and an unavoidable impurity, Bi is dispersed as particles of a Bi phase in the Cu alloy layer, and the mass ratio of the particles having a particle size of 2 to 50 μm and a circularity of 0.1 to 0.7 is 30% or more in the entire Bi phase in the Cu alloy layer, so that the particles of the Bi phase are uniformly dispersed in the Cu alloy layer. Therefore, the particles of the Bi phase in the Cu alloy layer are sequentially exposed to a sliding surface as wear of the sliding material progresses while excessive flow-out of molten Bi is prevented, so that improved seizure resistance is achieved.

摘要： A wheel bearing apparatus incorporating a rotation speed detecting apparatus has an outer member, an inner member, double row rolling elements, a pulser ring, a cup-shaped sensor cap and a rotation speed sensor. The sensor cap is press-formed from anti-corrosion steel sheet into a cup-shaped configuration with a cylindrical fitting portion, to be press-fit into the end of the outer member, and a bottom portion, extending radially inward from the fitting portion to cover the inner-side end of the inner member. The rotation speed sensor is oppositely arranged so that it abuts or is positioned in close proximity to the bottom portion and accordingly the pulser ring. The rotation speed sensor and pulser ring oppose one another a predetermined axial air gap via the bottom portion. An elastic member is pressed and elastically deformed between the fitting portion of the sensor cap and the end of the outer member.

摘要： A wave generator (4) of a wave gear device (1) is equipped with a rigid cam plate (5) and a wave bearing (7). The wave bearing (7) comprises an oval raceway surface (5b) formed on the oval outer peripheral surface (5a) of the rigid cam plate (5), a flexible bearing ring (8) equipped with a circular raceway surface (8a), and multiple balls (10) inserted in the race (9) formed between oval raceway surface (5b) and circular raceway surface (8a). A ball insertion hole (11) is formed at the outer perimeter edge of the rigid cam plate (5) at a region above the minor axis Lmin of the oval where there is substantially no load; from here, the balls (10) are inserted into the race (9), after which the hole is closed by a plug (12). It is easy to insert the balls (10) through the ball insertion hole (11), and the service life of the bearing is not reduced since the ball insertion hole (11) is formed.
