摘要： A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is not wasted, and which does not impair work environment by contaminating floor surface etc. A traction drive power transmission device has at least one drive roller (12a), a follower roller (12b), and a circular cylinder-like shaft (11). The shaft (11) is held between the drive roller (12a) and the follower roller (12b). When the drive roller (12a) is rotated, rotational force by the rotation is transmitted to the shaft (11) to drive it in its axial direction. The device has a lubrication oil-delivering portion (20) with application bodies (22-1, 22-2) for applying a lubrication oil only to portions where the shaft (11) is in contact with the drive roller (12a) and the follower roller (12b).

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 comprises a screw shaft, a hollow cylindrical nut member, balls, a ball returning means and a pair of deflectors. The screw shaft has a helical ball running groove. The nut member has a helical ball running counter-groove facing on the helical ball running groove of the screw shaft, and has a pair of ball-passing holes for connecting inner and outer surfaces of the nut member with each other. The balls are arranged between the ball running groove and the ball running counter-groove. The ball returning means is arranged on the outer surface of the nut member, for connecting the ball-passing holes with each other. The deflectors are disposed so as to be respectively correspondent with the ball-passing holes, for picking up the balls from the ball running groove to transfer the thus picked up balls into the ball-passing hole. Each of the deflectors comprises a ring-shaped base member fitted in an opening end of the nut member, and a ball-picking-up member projected from the base member. The ball-picking-up member is inserted in the ball running counter-groove so as to take a prescribed position of the ball-picking-up member relative to the ball-passing hole.

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.
