摘要： The rolling guide unit has a track rail formed with raceway surfaces, a casing moveable relative to the track rail and having raceway surfaces at positions facing the raceway surfaces of the track rail, and a number of cylindrical rolls that run rolling between the facing raceway surfaces. An end portion of that raceway surface of the track rail which is heavily loaded with a distributed load is crowned to make the raceway surface at the end portion curved, thereby eliminating uneven load and therefore dents and flaking of the raceway. This enhances durability and sliding characteristics of the raceway surfaces.

摘要： There is disclosed an infinite circuit using rolling bearings for providing the rectilinear motion. This circuit comprises: rolling elements consisting of rollers or balls; rolling bearings, constituted by the rolling elements, for providing the infinite rectilinear motion by endlessly circulating the rolling elements in an infinite circuit while keeping the direct contact relation with each other; rectilinear track and return passages; two direction reversing passages which connect both ends thereof. The direction reversing passage consists of two quarter-circular passages and an intermediate rectilinear passage provided therebetween. The cross section of each rolling element has the same diameter. In this invention, the traveling amount of each rolling element at each position in the infinite circuit can be made uniform, thereby minimizing the stick slip of the rolling elements while they are rolling in the circuit, so that it is possible to obtain the infinite circuit with less sliding resistance. Also, the moving direction of the rolling elements can be smoothly reversed.
摘要翻译：公开了一种使用滚动轴承提供直线运动的无限循环。该电路包括：滚子或滚珠组成的滚动元件; 由滚动元件构成的滚动轴承，用于通过使滚动元件在无限循环中循环循环同时保持彼此的直接接触关系来提供无限直线运动; 直线轨道和返回通道; 连接其两端的两个方向反转通道。方向反转通道由两个四分之一圆形的通道组成，中间的直线通道设置在它们之间。每个滚动元件的横截面具有相同的直径。在本发明中，可以使无限回路中的每个位置上的每个滚动元件的移动量均匀，从而使滚动元件在电路中滚动时的滑移最小化，使得可以获得无限电路具有较小的滑动阻力。此外，滚动元件的移动方向可以顺利地反转。

摘要： A roller-cage assembly for use in a bearing includes a cylindrical cage provided with a plurality of openings extending axially and spaced apart from one another circumferentially and a plurality of rollers, each of which is received in a corresponding one of the openings. Each opening is defined by a pair of oppositely disposed side guide surfaces and a pair of oppositely disposed end guide surfaces, whereby the distance between the pair of oppositely disposed side guide surfaces is larger than the diameter of the roller and the distance between the pair of opposite end guide surfaces is larger than the length of the roller, so that the roller may rotate freely within the opening. Also provided are at least a pair of oppositely disposed outer projections, which project oppositely from the pair of oppositely disposed side guide surfaces at their outermost locations, and at least a pair of oppositely disposed inner projections, which project oppositely from the pair of oppositely disposed side guide surfaces at their innermost locations, whereby the distance between the tips of each pair of the oppositely disposed inner and outer projections is smaller than the diameter of the roller. Thus, the roller is prevented from being undesirably removed from the cage radially by the inner and outer projections, axially by the pair of end guide surfaces, and circumferentially by the pair of side guide surfaces.
摘要翻译：用于轴承的滚子保持架组件包括：圆柱形保持架，其设置有沿轴向轴向间隔开的多个开口，以及多个辊，每个辊容纳在相应的一个开口中。每个开口由一对相对设置的侧引导表面和一对相对设置的端部引导表面限定，由此一对相对设置的侧引导表面之间的距离大于辊的直径和一对相对端引导表面大于辊的长度，使得辊可以在开口内自由旋转。还设置有至少一对相对设置的外突出部，其在最外侧位置与所述一对相对设置的侧引导表面相对地突出，以及至少一对相对设置的内突出部，所述内突起与所述一对相对布置侧引导表面在其最内部位置处，由此每对相对设置的内部和外部突起的尖端之间的距离小于辊的直径。因此，防止辊被内外凸出部沿轴向地由一对端引导表面沿周向不期望地从保持架中移除，并且被一对侧引导表面周向地移除。

摘要： The structure of the cross roller bearing does not require fixing bolts, rivets or holders for the divided races and can firmly assemble the divided races together. The cross roller bearing includes the inner race having a raceway groove and an engagement surface on its outer circumferential surface and the outer race that fits over the inner race and has a raceway groove and an engagement surface on its inner circumferential surface. The outer race is divided into two axially divided races. A large number of rollers are installed in a raceway formed between the raceway grooves. The engagement surface of the inner race is formed with recessed portions at axially inner portions, and the engagement surfaces of the divided races of the outer race are formed with raised portions that rotatably fit in the recessed portions. Thus, the divided races are assembled onto the inner race so that they are rotatable but axially locked relative to the inner race.
