摘要： The present invention provides a track rail mounting structure of a rectilinear guide apparatus comprising a track rail having a rotating/running surface where a plenty of rotating/running bodies rotate and run; an endless circulation route for guiding the plenty of rotating/running bodies; and a slider movably arranged with respect to the track rail via the rotating/running bodies; wherein a base where the track rail is mounted has a groove for inserting a bottom portion of the track rail, so that the bottom portion of the track rail is inserted into the groove, and a pressure member is provided for pressing at least one side surface of the track rail toward an inner side surface of the groove. As has been described above, since the pressure member is provided to press the side surface of the track rail toward the inner side surface of the groove, the side surface of the track rail is pressed by the pressure member so as to press the opposite side of the track rail to the inner side surface of the groove or both side surfaces of the track rail are pressed by the pressure member so as to be fixed to the track rail. Accordingly, even when a thermal expansion difference is caused between the track rail and the base by a temperature change, a contact portion of the pressure member slides along the side surface of the track rail so as to absorb the thermal expansion difference and accordingly, no distortion is caused in the track rail.

摘要： This invention relates to improvement of a ball screw unit in which a nut member meshes with a screw shaft via a plurality of balls circulating endlessly. The balls are disposed freely rotatably in line at a predetermined interval in a ball arranging member formed in a belt-like shape. If a relative rotation occurs between the nut member and screw shaft, the balls circulate in the infinite circulation path with the ball arranging member. Guide pieces are projected to both sides of the ball arranging member and guide grooves for accommodating each of the guide pieces are formed along the entire circumference of the infinite circulation path. Therefore, the ball arranging member is introduced by the guide grooves and circulates in the infinite circulation path without being fluttered.

摘要： A ball screw device having a novel ball circulation structure suitable for a screw shaft with a large lead, optimum for downsizing and weight saving of a nut member, capable of being manufactured at low cost, and capable of exhibiting high reliability even under severe use conditions. In a ball screw device where a screw shaft and a nut member are screwed to each other through an intermediation of a large number of balls, a no-load ball path which forms an infinite circulation path for the balls is constituted by a no-load ball groove spirally formed in an inner peripheral surface of a through-hole of the nut member and by a pair of direction change grooves which communicatively couple a load rolling groove and the no-load ball groove to each other so as to complete the infinite circulation path as a closed loop.
