摘要： In a retaining piece interposed between the adjacent rolling balls, a concave surface of each of both side surfaces of the retaining piece where it contacts with the spherical surfaces of the balls is configured to partly contact with the spherical surface of the ball. The concave surface includes a linear contact portion to be in contact with the ball and an approximate curved surface having the radius of curvature approximate to that of the ball, which is located on the inner side of the linear contact portion. In addition, recesses which are joined to the gate portion and the ejector pin in a molding process are formed in the concave surfaces. A recess is formed at the joining portion or near a parting line. Fins formed in the molding process are capable to be put into the recess.

摘要： In the present linear guide bearing, the center of curvature O′ of a ball reversing passage 27 is shifted to a return side ball passage 25 side by a given amount m when compared with the center of curvature O′ of a conventional guide bearing. Due to this, not only the radius of curvature of a concave-arc-shaped groove 29 formed in each end cap 9 is reduced by a given amount m but also the concave-arc-shaped groove 29 is shifted to the return side ball passage 25 side by a given amount m, when compared with the conventional guide bearing. Thus, an angle &agr; formed between a line connecting the leading end of a tongue portion 31 to the center of curvature O′ of a ball reversing passage 27 and the moving-direction end face of a bearing main body 7, can be reduced significantly when compared with the conventional bearing.

摘要： In order to offer a linear working unit which is a linear working unit capable of accurately driving two movable members in mutually reverse directions, i.e., leftward and rightward, with a single driving means and yet formed in a construction highly accurate in performance but compact and moderately priced, according to the present invention, a left-hand thread part and a right-hand thread part are formed on a single feed screw, with a nut block being joined independently with each of the left-hand thread part and the right-hand thread part and with the respective nut blocks being installed on a guide rail, and rolling elements are set in the space between the rolling groove formed for the rolling elements in the guide rail and the rolling grooves formed in the nut blocks, so that the nut blocks are kept free to slide in the axial direction by the effect of the rolling motion of these rolling elements. Thereby, the linear working unit is capable of operating the two nut blocks so as to make their highly accurate movements in the mutually reverse directions, i.e., leftward and rightward, through control of a single feed screw and, as these nut blocks are built into the same guide rail, the linear working unit can offer the additional advantage that it can be formed in a non-bulky structure comprised of a smaller number of items of component parts and can yet be operated in a simple manner.
摘要翻译：为了提供一种线性工作单元，该线性工作单元能够使用单个驱动装置在相反的方向（即向左和向右）上精确地驱动两个可动构件，并且还以高度准确的结构形成为紧凑和紧凑的结构，价格适中，根据本发明，在单个进给螺杆上形成左手螺纹部分和右旋螺纹部分，其中螺母块与左旋螺纹部分和右旋螺纹部分中的每一个独立地接合，手螺纹部分和相应的螺母块安装在导轨上，并且滚动元件设置在形成于导轨中的滚动元件的滚动槽和形成在螺母块中的滚动槽之间的空间中，使得螺母块通过这些滚动元件的滚动运动的作用被保持在轴向方向上自由滑动。因此，线性加工单元能够操作两个螺母块，以便通过单个进给螺杆的控制使得它们在相反的方向（即，向左和向右）上进行高精度的运动，并且因为这些螺母块被内置相同的导轨，线性工作单元可以提供额外的优点，即其可以形成为由较少数量的部件组成的非笨重结构，并且还可以以简单的方式操作。

摘要： A nut block, which is driven by a feed screw shaft and which is movable axially within a guide rail having a U-shaped cross section, is provided with extending portions extending laterally from both upper side portions thereof. The extending portions are positioned near the upper surfaces of both side walls of the guide rail to cover these upper surfaces. A flexible seal plate of a magnetic material is provided to cover the whole length of the opening in the guide rail. The seal plate forms an expanded portion expanding upwardly at a portion corresponding to the nut block with the movement of the nut block. The seal plate has opposite ends respectively fixed to opposite axial ends of the guide rail. Both edge portions of the seal plate are attracted to rubber magnets mounted on the upper surfaces of the side walls of the guide rail.

摘要： In a feed screw apparatus composed of a feed screw shaft and a nut engaged with the feed screw shaft which is movable in the axial direction, a guide rail member having ball rolling grooves in both side surfaces is disposed beneath the feed screw shaft in parallel to and slightly spaced therefrom. The bottom portion of the nut is extended downwardly at both lateral sides to form side walls constituting a linear guide section which sandwiches the guide rail member and has ball rolling grooves in the inner surfaces of the side walls. The outer surfaces of the side walls of the linear guide section are formed with ball rolling grooves, and half tubes respectively facing these ball rolling grooves to form ball return paths are fixed between end caps which are secured at opposite ends of the linear guide section.
