摘要： An attaching device for a bellows type dust cover of a linear guide apparatus includes a plate-shape main body and a bellows attaching plate portion integral with the plate-shape main body. The plate-shape main body has fitting plate portions which are formed by bending lower edge portions of both lateral side plate portions respectively inwardly at right angles so that both the fitting plate portions horizontally oppose each other. The fitting plate portions are respectively fitted into ball rolling grooves formed in both lateral sides of a guide rail, or into retainer relief grooves formed in groove bottoms of the ball rolling grooves. Thus, the plate-shape main body straddles an upper surface of the guide rail and sandwiches both lateral sides of the guide rail so that it is securely held to the guide rail. The bellows attaching plate portion is provided at one axial end of the plate-shape main body perpendicularly to the upper surface of the plate-shape main body. The bellows attaching plate portion has screw holes. A bellows which covers the guide rail has one end fixed to the bellows attaching plate portion by screws and the other end fixed to a slider.
摘要翻译：线性导向装置的波纹管式防尘罩用安装装置包括板状主体和与板状主体一体的波纹管安装板部。板状主体具有嵌合板部，其通过使两侧板部分的下边缘部分分别以直角向内弯曲而形成，使得两个嵌合板部分水平地彼此相对。装配板部分分别装配在形成在导轨的两个侧面上的滚珠滚动槽中，或者嵌入到形成在滚珠槽的凹槽底部的保持器释放槽中。因此，板状主体跨越导轨的上表面，并将导轨的两侧侧夹住，使其牢固地保持在导轨上。波纹管安装板部分在板状主体的一个轴向端部垂直于板状主体的上表面设置。波纹管安装板部分具有螺纹孔。覆盖导轨的波纹管的一端通过螺钉固定在波纹管安装板部上，另一端固定在滑块上。

摘要： Three rows of ball rolling grooves 23A to 23C are formed in each side of a guide rail 21, while being vertically arrayed. Three rows of ball rolling grooves 25A to 25C are also formed on the inner surface of each of the legs of a slider 22. The ball rolling grooves 25A to 25C are respectively disposed in opposition to the ball rolling grooves 23A to 23C to thereby form ball sliding passages 26A to 26C. In either of the upper or lower ball rolling passage 26A or 26C, each ball contacts, at four points, with the surfaces of the ball rolling groove 23A or 23C of the guide rail 21 and the ball rolling groove 25A or 25C of the slider 22. In the remaining ball rolling passages, each ball contacts at two points with the surfaces of the ball rolling grooves. One of lines L1 and L4, each of which connects two opposite contact points of those four ones in the upper or lower ball rolling passage is oriented in the same direction as of lines L2 and L3 connecting the contact points in the remaining ball rolling passages. With such a construction, the upper, medium and lower rows of ball trains receive all loads acting on the slider in share, whereby the linear guide assembly exhibits its maximum load capacity against the loads.

摘要： In a linear guide apparatus including a guide rail, a slider hanging over the guide rail to freely move with respect to the guide rail through the rolling movements of balls and a ball retainer mounted within the slider for holding the balls, the ball retainer is formed of plate-shaped metal and includes two ball holding parts respectively formed by bending the two side edge portions of a thin metal plate and two thin-plate shaped inner seal parts extending along and fixed integrally to the ball holding parts with the end portions thereof slidingly contactable with the upper surface of the guide rail. The ball retainer has not only a ball retainer function to be able to hold a large number of balls loaded into the ball rolling grooves formed in the slider but also an inner seal function to prevent foreign matter which have passed through side seals into the slider from entering into the ball rolling grooves.

摘要： Each of the pair of under seals which are respectively attached to the lower surfaces of the side walls of a slider includes an elongate core metallic plate and a rubber member secured to the core metallic plate and having a lip portion protruding inwardly from the inner edge of the core metallic plate. Each of the end caps attached to opposite ends of a slider main body is formed with an under seal holding groove in a joining surface of each leg portion of the end cap. The slider main body is formed with a stepped recess portion to accommodate the under seal in the lower surface of each side wall. The opposite ends of the under seal are fitted into and held in the under seal holding grooves of the end caps and the remainder of the under seal is accommodated in the stepped recess portion of the slider main body. The lip portion os the under seal is slidingly in contact with the lateral side of the guide rail to prevent dust from entering into the inside of the slider.

摘要： An upper ball-retainer for holding the balls in a pair of upper ball rolling grooves formed in the inner surface of the slider main body is made of a synthetic resin and has a rectangular dish shape. Supporting portions protrude axially from axial opposite ends of the ball-retainer, and the supporting portions are respectively inserted into supporting holes formed in the end caps attached to opposite ends of the slider main body so that the upper ball-retainer is accommodated in a space between the upper surface of the guide rail and the inner surface of the slider main body. A ball holding groove having a circular arc cross section is formed in each of the lateral sides of the upper ball-retainer and extends over the whole axial length thereof to hold the balls against the corresponding ball rolling groove of the slider main body. A lip portion of a thin wall is formed at lower end of the ball holding groove and protruding downwardly therefrom. The lip portion is deformable elastically in a direction to expand the ball holding groove and, normally, the lip portion together with the ball rolling groove of the slider main body has a width narrower than the diameter of the ball.

摘要： A linear guide apparatus includes a guide rail and a slider mounted on the guide rail movable in the axial direction through balls interposed between corresponding ball rolling grooves of the guide rail and the slider. End caps are joined to opposite ends of the slider, and each of the end caps has a ball circulating path formed therein to connect the ball rolling grooves of the guide rail and the slider to ball rolling paths formed in the slider. An oil feed groove is formed in the end cap, and lubricating oil is normally supplied to the ball circulating path from an oil feed nipple attached to the front of the end cap through the oil feed groove. A blind hole for mounting the oil feed nipple is formed in the side of the end cap as a spare oil feed hole at the time of molding of the end cap so that the bottom of the blind hole is located close to the oil feed groove. When it is necessary to change the position of the oil feed nipple from the front to the side of the end cap, the bottom portion of the blind hole is easily opened to connect the blind hole to the oil feed groove.
