    摘要: Provided is a roller screw having an unloaded roller return path of new shape capable of moving rollers smoothly.
    The roller circulation path of the roller screw has the unloaded roller return path and a loaded roller rolling path. The unloaded roller return path 10 is twisted so that while each roller 4 moves in the unloaded roller return path 10 its central axis is inclined. In a cross sectional shape of the twisted part of the unloaded roller return path 10, each of paired side surface corresponding parts 25c and 25d facing respective side surfaces of the roller 4 is convex toward the inside of the unloaded roller return path 10.

    摘要: Provided is a motion guide device having a scooping portion that is not damaged even when a moving member is moved at high speed.
    When seen in an axial direction of a track shaft 1, a direction change path 10 is inclined relative to a contact angle line L1 (line connecting a center C of a ball 3 and a bottom P1 of a ball rolling groove 1a). The direction change path 10 including a scooping portion 17 has a cross section of Gothic arch groove shape formed of two arcs R1 in such a manner that the ball 3 is in contact with the direction change path 10 at two points. The direction change path 10 is twisted in such a manner that a locus 18 of the top of the Gothic arch groove shape approaches the contact angle line L1 at the scooping portion 17.

    摘要: The present invention provides a roller screw capable of circulating rollers smoothly.
    A roller screw of the present invention has a screw shaft 1 having a roller rolling surface 1a spirally formed with a lead on an outer surface thereof; a nut 2 having a roller rolling surface 2a spirally formed on an inner surface thereof to face the roller rolling surface 1a of the screw shaft 1; and a plurality of rollers 4 arranged in a rolling path 3 between the roller rolling surface 1a of the screw shaft 1 and the roller rolling surface 2a of the nut 2 and moving around the screw shaft while rotating on rotation axes of the rollers. In this roller screw, each of the rotation axes 4a of the rollers 4 substantially crosses a center line 1b of the screw shaft 1. Since each of the rotation axes 4a of the rollers 4 crosses the center line 1b of the screw shaft 1 (in other words, the rollers 4 arranged in the rolling path 3 are not skewed from the beginning) even when the rolling path 3 has the lead, the roller 4 are allowed to move smoothly.

    摘要: Provided is a rolling guiding device which makes it possible to easily provide a movement block with an endless circulation path for the balls even in a case of a small-sized rolling guiding device using balls of a relatively small diameter and which can be produced easily and at low cost. In one surface of a movement block (2) opposed to a rolling groove (13) of a raceway rail (1), there is formed a track groove (21) through which balls (3) makes an endless circulation. The track groove (21) is composed of: a load straight-line groove (22) which allows, between the track groove (21) and the rolling groove (13) of the raceway rail (1), the balls (3) to roll while bearing a load; a pair of ball deflection grooves (24) and (24) respectively provided at both ends of the load straight-line groove (22) and adapted to release the balls (3) having rolled through the straight-line groove (22) from the load and to change their rolling direction, causing the balls (3) to leave the rolling groove (13) of the raceway rail (1); and a non-load straight-line groove (23) for transferring the ball (3) in a non-load state from one deflection groove (24) to the other ball deflection groove (24).

    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).

First divided shading plate 22A is loosely fitted to and supported by (not adhere to) the rotating shaft 23 and rotates around the shaft 23. Second divided shading plates are fixed to the rotating shafts 23 and rotate by rotating movement of the shafts 23. A driving shaft 24 is connected longitudinally to (not adhere to) an edge of the first divided shading plate 22A and supply power to rotate the first divided shading plate 22A. Recesses C are formed at the center of upper short side and at the center of lower short side of the first divided shading plate 22A and the first divided shading plate 22A and the second divided shading plates 22B which form one and the same shading plate 22 are so constructed that their short sides are overlapped each other.
