    • A rolling guide unit in which the cross-section of a track rail is U-shaped wherein grinding processing of a track provided on the inside surface is facilitated. In addition, the thickness of the overall unit can be decreased by employing a self-traveling unit in which a motor is installed on a slider of a rolling guide unit. Grinding is facilitated by a split rail along one of the side walls of a track rail, and grinding can be performed with the split rail removed. In addition, since the entire outside surface of the side wall of the track rail can be used as a track for a rolling member, even if the track rail is flat, it is able to sufficiently transfer driving force, thereby allowing the thickness of the entire unit to be decreased.
    • 一种滚动导向单元,其中轨道轨道的横截面为U形,其中促进了设置在内表面上的轨道的研磨处理。 此外,通过使用其中电动机安装在滚动导向单元的滑块上的自行车单元,可以减小整体单元的厚度。 通过沿轨道轨道的一个侧壁的分割轨道来促进研磨,并且可以在拆下分离轨道的情况下进行研磨。 此外,由于轨道轨道的侧壁的整个外表面可以用作滚动构件的轨道,所以即使轨道平坦,也能够充分地传递驱动力,从而允许 整个单位要减少。

    • A linear motion rolling guide unit in which rolling elements of one side are in four-point contact with raceway surfaces of one of two raceways formed by raceway grooves in a rail and grooves in a casing and rolling elements of the other side are in two-point contact with raceway surfaces of the other raceways. Depending on the direction in which load is applied to the slider, the number of raceway surfaces the rolling elements contact is changed to allow machining errors of the raceway grooves and to give room of the machining accuracy so that even when the casing is applied with an uneven load the slider can slide smoothly on the track rail.
    • 一种直线运动滚动导向单元,其中一侧的滚动元件与轨道中的轨道槽形成的两个滚道中的一个的滚道表面与另一侧的滚动元件中的槽中的滚道中的四个点接触, 与其他跑道的滚道面接触。 根据向滑块施加负载的方向,滚动体接触的滚道面的数量发生变化,从而允许滚道槽的加工误差,并且给予加工精度的空间,使得即使在壳体被施加 载荷不均匀,滑块可以顺利滑轨。

    • A ball screw driven linear motion rolling contact guide unit includes a rail having a generally U-shaped cross section and a ball screw shaft and a slider received in the rail and operatively coupled to the ball screw shaft. A plurality of rolling members are interposed between the slider and the rail. The rail has a bottom wall formed with a trench in which a quantity of damping oil is reserved. The slider is provided with a projection which projects into the trench to thereby define a squeeze film damper mechanism. The slider is also provided with an endless circulating path, including a load path section, a return path section and a pair of curved connecting path sections, each connecting the corresponding ends of the load and return path sections, whereby the return path section is located lower in level than the load path section.
    • 滚珠丝杠驱动的直线运动滚动接触引导单元包括具有大致U形横截面的轨道和滚珠丝杠轴以及容纳在轨道中并可操作地联接到滚珠丝杠轴的滑块。 多个滚动部件插入滑块和导轨之间。 轨道具有形成有沟槽的底壁,其中预留有一定数量的阻尼油。 滑块设置有突出部,其突出到沟槽中,从而限定挤压膜阻尼机构。 滑块还设置有环形循环路径,其包括负载路径部分,返回路径部分和一对弯曲连接路径部分,每个连接路径部分连接负载和返回路径部分的相应端部,由此返回路径部分位于 电平低于负载路径部分。

    • A machine for testing a centrifugal load of a bearing including an outer race member, comprising a supporting frame including a sun ring, and a rotational main shaft. The rotational main shaft includes mounting portions for mounting the bearing to be tested. The mounting portions includes a mounting shaft for mounting the bearing to be tested and a supporting bracket for supporting the mounting shaft. The mounting shaft is arranged in the supporting bracket in parallel with the rotational main shaft in such a manner that a part of an outer peripheral surface of the outer race member is projected radially outwardly from the supporting bracket. The mounting shaft is journaled to a supporting bracket with a displacing margin in a radially outward direction to the rotational main shaft. An inner peripheral surface of the sun ring is used as a track to be rolled with the outer race members of the respective bearings to be tested. The bearings are rotated around the rotational shaft and around their own axes along the inner peripheral surface of the sun ring.
