摘要： A linear guide apparatus which can be applied to both straight rail and curved rail comprising a pair of upper and lower rolling grooves and for rolling members are formed in each side surfaces of a guide rail. A pair of upper and lower grooves for loaded rolling members, which respectively correspond to the rolling grooves, are formed in each inner surfaces of a slider which straddle the guide rail. One of the rolling grooves is a straight rolling groove which is formed to be parallel with the corresponding straight groove formed in the opposite inner surface of the slider. The other of the rolling grooves is a curved rolling groove in circular arc shape which has the same curvature as the corresponding curved rolling groove formed in the opposite inner surface of the slider.

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.
