摘要： In a miniature linear guide apparatus, a return guide main body fitting groove which crosses a curved path is formed in a joining end surface of each end cap. A return guide attaching portion fitting groove which extends upwardly from the return guide main body fitting groove is formed in each end cap. A return guide consisting of a return guide main body and a return guide attaching portion formed co-axially with the return guide main body are respectively fitted into the return guide main body fitting groove and the return guide attaching portion fitting groove with a tight fit.

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 guide rail or slider body manufacturing method for a linear guide device providing a guide rail and a slider mounted on the guide rail, mounting reference surfaces formed on the guide rail or slider body and/or the surfaces of ball rolling grooves formed therein are finished by grinding, and are subjected to rust-proofing surface treatment with protecting members fitted to the surfaces thus finished. Similarly in a method of manufacturing a ball screw device providing a screw shaft and a ball screw nut engaged with the screw shaft, the surfaces of ball rolling grooves formed in the screw shaft and the ball screw nut are finished by grinding, and are subjected to rust-proofing surface treatment with protecting members fitted to the surfaces thus finished. In the methods, the rust-proofing surface treatment is carried out for the surfaces except those which should not be covered with such a rust-proofing film layer for their precision.

摘要： Nut 2 in threadable engagement with the screw shaft 1 of a feed screw apparatus is fitted with a lubricant supply device 30 which also serves as a seal. This device is made of a lubricant-containing rubber or synthetic resin and has a plurality or projections 31 in the inner surface that contact the outer circumference of the screw shaft 1. The lubricant in said rubber or synthetic resin slowly seeps out unoxidized for an extended period of time to perform effective lubrication.

摘要： In a linear guide device comprising: a guide rail fixedly secured to the mounting surface of a supporting member such as a machine bed; and a slider slidably engaged with the guide rail. Recesses are formed in the mounting surface of the guide rail and in the mounting surface of the supporting member, respectively, to provide a space therein. The space thus provided is filled with a hardenable filling material. The hardenable filling material is solidified therein, thus serving as a key held between the guide rail and the supporting member to prevent the guide rail from being displaced sidewards.
