    摘要: A motion guide device having a novel scoop section structure whose scoop section is not likely to break even if a movement member is moved at high speed. A scoop section (22) of a movement block (12) scoops balls (13) that roll in a ball rolling groove (11a) of a raceway rail (11) and introduces them into no-load ball return paths (17, 20). The scoop section (22) is formed in a Gothic arch groove shape in which the scoop section (22) is in two-point contact with a ball (13). In a cross-section orthogonal to the advance direction of the balls (13), an angle (contact angle a) formed by a line L1 that connects a point P at which the scoop section (22) and a ball (13) are in contact and the center C of the ball (13) and a line L2 that connects the center of the ball (13) and a bottom (22a) of the Gothic arch groove-shaped scoop section (22) exceeds 30 degrees and is not more than an angle ? formed by a line L3 that connects the center C of the ball (13) rolling in the ball rolling groove (11a) of the raceway rail (11) and an edge (35) of the ball rolling groove (11a) of the raceway rail(11) and the line L2 that connects the center C of the ball (13) and the bottom of the ball rolling groove (11a).

    摘要: A linear motion device, characterized in that a raceway shaft and a slide member are relatively slidably engaged with each other through rolling elements, for example, balls and rollers, similarly to linear guiding apparatuses, ball screws and ball splines. An improvement has successfully obtained on the linear motion device which has a lubricating oil supply member that applies lubricating oil to the surface of the raceway shaft. The linear motion device comprises a raceway shaft formed with a pathway for the rolling elements, a slide member engaged with the raceway shaft with the rolling elements interposed between, so that it is slidable relative to the raceway shaft, and a lubricating oil supply member mounted on the slide member and adapted to apply lubricating oil to the surface of the raceway shaft as the slide member performs its relative sliding motion. Further, the lubricating oil supply member comprises a lubricating oil applying body in contact with the raceway shaft to apply lubricating oil to the raceway shaft, a lubricating oil occlusion body arranged adjacent to the lubricating oil applying body to absorb and hold the lubricating oil and also supply the lubricating oil to the lubricating oil applying body, and an oil flow control means to control the amount of lubricating oil supplied from the lubricating oil occlusion body to the lubricating oil applying body.

    摘要: The present invention provides a screw device enabling insulation of sounds occurring from the inside of the screw device when circulating rolling elements. The screw device includes: a screw shaft 1 having a spiral rolling-element rolling groove 1a on an outer circumferential surface; a nut body 2 having a spiral loaded rolling-element rolling groove 2a on an inner circumferential surface to oppose the rolling-element rolling groove 1a of the screw shaft 1 and having therein a rolling-element returning passage 6 to return rolling elements 3 rolling in a loaded rolling-element rolling passage 10 formed between the loaded rolling-element rolling groove 2a and the rolling-element rolling groove 1a of the screw shaft 1; a circulation member 9 attached to an end face of the nut body 2 and provided with a direction changing passage 5 to connect the loaded rolling-element rolling passage 10 and the rolling-element returning passage 6; and a sound insulating member 11 attached to the nut body 2 to which the circulation member 9 is attached and formed to have an inner circumferential surface coming into contact with the screw shaft and to cover the circulation member 9.
