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： A dynamic equivalent load P is calculated from data information of a rolling bearing. Next, a reliability coefficient a1 is determined, a lubrication parameter aL corresponding to a used lubricant is calculated, and a contamination degree coefficient ac is determined in consideration of a material coefficient. A fatigue limit load Pu is calculated on the basis of the data information. Thereafter, a load parameter {(P−Pu)/C}·1/ac is calculated. On the basis of the lubrication parameter aL and the load parameter {(P−Pu)/C}·1/ac, a life correction coefficient aNSK is calculated with reference to a life correction coefficient calculation map. The bearing life LA is calculated by LA=a1·aNSK·(C/P)p.

摘要： The present invention provides a rolling bearing in which an oxide layer of an iron/chromium oxide series is formed at a thickness of from 1 to 1000 nm to at least one of raceway surfaces of bearing rings or rolling contact surfaces of rolling elements and a manufacturing method thereof. The oxide layer can inhibit hydrogen formed by decomposition of water incorporated in the lubricants from intruding into the matrix of the bearing members, thereby preventing early peeling for the raceway surfaces of the bearing rings or the rolling contact surfaces of the rolling elements and, thus, greatly improving the rolling life. The oxide layer can be formed simply by merely tempering the bearing member and then applying a re-heating treatment in air at a temperature lower than the tempering temperature.

摘要： A rolling bearing long in service life in which the rolling contact surfaces of the rolling elements and the mating member thereof are prevented from peeling damage. In a rolling bearing used in boundary lubrication state, the surface roughnesses of the rolling contact surfaces of each of the rolling elements and the mating member thereof are in a range of from 0.15 to 0.5 .mu.mRa when represented by central line average roughness, and the ratio thereof is 3 or smaller, whereby the surface roughnesses can be obtained in combination which are most suitable for decreasing the probabilities of the surface damage being caused in the surface layers of the rolling contact surfaces of the mating member and each rolling element. Hence, stresses are locally set up in the surface layers of the rolling contact surfaces which are smaller than the allowable shearing stress, so that the rolling contact surfaces are prevented from the peeling damage.
摘要翻译：一种使用寿命长的滚动轴承，其中滚动元件及其配合件的滚动接触表面被防止剥离损伤。在用于边界润滑状态的滚动轴承中，当以中心线平均粗糙度表示时，每个滚动元件及其配合构件的滚动接触表面的表面粗糙度在0.15至0.5μmRa的范围内，并且比例为3以下，由此可以组合获得最适合于降低配合构件和各滚动体的滚动面的表面层的表面损伤的概率的表面粗糙度。因此，在滚动接触面的表面层局部地设置应力小于允许的剪切应力，能够防止滚动面的剥离损伤。
