摘要： A linear motion guide unit restrains fluctuations in sliding friction and generation of heat by correcting the postures of rollers having been inclined in a no-load area such that their axes become orthogonal to a guide surface of a carriage to thereby introduce the rollers in proper postures into a load area. A retainer plate of the guide unit has a guide surface for guiding end surfaces of the rollers and has protrusions protruding from the guide surface at its opposite end portions facing crownings of the carriage. The rollers rolling from a turnaround passage to a load-carrying race are pressed by the protrusions toward the guide surface of the carriage so as to be arrayed in such a posture that the axes of the rollers become orthogonal to the guide surface on the inlet side of the crowning of the carriage, whereby the occurrence of roller skew is prevented.

摘要： In the linear motion guide unit, a retainer plate for retaining rolling elements, or rollers, is prevented from deformation so as to smoothly guide the rollers. The retainer plate is composed of a retainer member, frame members fitted into respective through holes formed in the retainer member, and a fixing member disposed in a longitudinally extending recess of the retainer member. The frame members form a predetermined gap between the fixing member and a carriage. Tightening forces of fastening bolts are not applied to the retainer member, thereby avoiding deformation of the retainer member.

摘要： A wear-proof tester to evaluate an anti-frictional performance of surface treatment carried on a needle cage. The needle cage is subjected to flex under the centrifugal force of composite revolution and rotation. Wear-proof test of surface treatment is carried by sliding contact between the outside circular surface of the retainer and the inside circular surface of the outside wheel. The retainer with no roller is fastened on a rotary shaft with leaving a clearance between them. A radial load is applied to retainer through a test outside wheel to get the retainer flexed to make sliding contact over a predetermined area between the outside circular surface of the retainer and the inside circular surface of the outside wheel. This wear-proof tester is applicable to the wear-proof tests of various materials other than the wear-proof test of the retainer made of various materials.

摘要翻译： 一种耐磨试验机，用于评估针笼上承载的表面处理的抗摩擦性能。 针笼在复合旋转和旋转的离心力下受到挠曲。 表面处理的耐磨试验是通过保持器的外圆周表面和外轮的内圆周表面之间的滑动接触进行的。 没有滚子的保持器固定在旋转轴上，在它们之间留有间隙。 通过测试外轮将径向载荷施加到保持器，以使保持器弯曲以在保持器的外圆周表面和外轮的内圆周表面之间的预定区域上滑动接触。 该耐磨试验机适用于各种材料的耐磨试验，而不是由各种材料制成的保持架的耐磨试验。
