摘要： A spline connection structure is provided with a shaft spline and a bore spline. The shaft spline is comprised of plural involute teeth formed on a shaft, while the bore spline is comprised of plural involute teeth formed on a hub and maintained in engagement with the teeth of the shaft spline. The hub is provided with at least one cylindrical hole and a thin wall portion facing a lower end portion of the cylindrical hole. The thin wall portion is pressed by a pressing member inserted in the cylindrical hole to widen an interval between at least two of the teeth of the bore spline, said at least two teeth being located in a vicinity of the thin wall portion, such that at least one of the at least two teeth is pressed against at least one associated tooth of the teeth of the shaft spline and is restrained to restrict movement of the hub relative to the shaft. At least one tooth of at least one of the shaft spline and bore spline, said at least one tooth being located in a vicinity of the thin wall portion, is provided with a cutout portion formed by cutting off the at least one tooth at a part thereof such that the cutout portion is located in a neighborhood of an end face of the hub located on a side opposite another end face of the hub located on a side of an end portion of the shaft.
摘要翻译：花键连接结构设置有轴花键和孔花键。轴花键由形成在轴上的多个渐开线齿组成，而孔花键由形成在轮毂上并与轴花键的齿保持接合的多个渐开线构成。毂设置有至少一个圆柱形孔和面向圆柱形孔的下端部的薄壁部分。所述薄壁部分被插入所述圆柱形孔中的按压构件按压以加宽所述孔花键的至少两个齿之间的间隔，所述至少两个齿位于所述薄壁部分附近，使得在所述至少两个齿中的至少一个齿被压靠在所述轴花键的齿的至少一个相关联的齿上并被限制以限制所述轮毂相对于所述轴的运动。所述至少一个所述轴花键和所述花键的至少一个齿，所述至少一个齿位于所述薄壁部分附近，所述至少一个齿设置有切口部，所述切口部通过在部分使得切口部位于位于位于轴的端部侧的轮毂的与另一端面相反的一侧的轮毂的端面附近。

摘要： A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided on the non-rotating side brake disk, and an oil groove is provided in a frictional engaging surface of this frictional material. It is configured such that, when a braking force is applied by a brake piston to the motor shaft, lubricant oil flowing into the brake case from a lubricant oil inlet port flows from the outer diameter side to the inner diameter side between the rotating side brake disk and the non-rotating side brake disk only through the oil groove. As a result, the lubricant oil having flowed into the brake case efficiently cools the frictional engaging surface.
