摘要： There is provided a steering system that is capable of suppressing backlash of a pulley and a reduction in strength due to temperature variations even if the pulley which is made of a resin is externally fitted with a nut member made of metal. A steering system (1) includes: a rack shaft (2) that is movable to be advanced and retracted in the axial direction; a cylindrical nut member (5) made of metal and threadably engaged with a spiral screw groove (21) formed in the outer peripheral surface of the rack shaft (2) via a plurality of balls (42); a pulley (6) made of a resin and externally fitted with the nut member (5) so as not to be rotatable relative to the nut member (5); a belt (90) wound around the pulley (6); an electric motor (40) that rotates the pulley (6) and the nut member (5) via the belt (90); and a retention ring (7), a plate spring portion (72) of which is disposed between the outer peripheral surface of the nut member (5) and the inner peripheral surface of the pulley (6) in an elastically deformed state. The retention ring (7) presses a second planar portion (6a) formed on the inner peripheral surface of the pulley (6) radially outward using a restoring force of the plate spring portion (72).

摘要： There is provided a ball screw that can prevent entry of foreign matter into the inside of a nut even when the particle size of the foreign matter is very small. The ball screw includes a gas supply portion that supplies a gas to an inner space (S) formed between an outer peripheral surface of a screw shaft (1) and an inner peripheral surface of a nut (2); and seals (5) respectively attached to both axial ends of the inner peripheral surface of the nut (2) and sealing openings at axial ends of the inner space (S). The seals (5) have sealability such that a pressure in the inner space (S) becomes higher than a pressure outside the inner space (S) by the gas supplied from the gas supply portion.

摘要： Provided are a nut, an attachment for nut and a screw shaft, which are fitted to a coating material coating device or a soldering device and can change a fixed position of the nut easier than that of a convention example even if any adhered matters generated when each device is used for a long time are fixed, and a soldering device using the same. The nut 10 screws on to the screw shaft 2 having a predetermined length. The nut 10 is provided with a non-meshing part 11 composed of a notch 12 that is formed parallel to a movement direction thereof by cutting off screw threads and a flange portion 13, which has connecting holes 14 for connecting another member. Under such a configuration, by forward and/or backward movement of the nut 10, the notch 12 functions as if it scraps the fixed matters 6.

摘要： An object of the present invention is to provide an electric linear actuator provided with the anti-rotation mechanism for the screw shaft which is able to achieve a simple structure and thus low manufacturing cost and to reduce the sliding friction and wear. According to the present invention, there is provided an electric linear actuator comprising a housing; an electric motor mounted on the housing; a speed reduction mechanism for reducing rotational speed of the electric motor via a motor shaft; a ball screw mechanism for converting rotational motion of the electric motor transmitted via the speed reduction mechanism to axial linear motion of a driving shaft; the ball screw mechanism comprising a nut formed with a helical screw groove on its inner circumference and supported by bearings mounted on the housing rotationally but axially immovably, and a screw shaft coaxially integrated with the driving shaft, formed with helical screw groove on its outer circumference corresponding to the helical screw groove of the nut, inserted into the nut via a large number of balls, and supported on the housing axially movably but not rotationally; and a blind bore formed on the housing for containing an end of the screw shaft characterized in that a sleeve for an anti-rotation of the screw shaft is fitted in the blind bore of the housing and is press-formed of steel sheet.
