20080245165 | SLIDE MECHANISM OF LINEAR TRANSMISSION APPARATUS - A slide mechanism of a linear transmission apparatus includes an actuating mechanism, a guide screw and a slide mechanism. The slide mechanism includes a fixing base, a primary guide rail, left and right secondary guide rails and a slide element. The fixing base has a through hole for passing the guide screw. The primary guide rail and each secondary guide rail are engaged to the guide screw and connected to the fixing base. The primary guide rail has a top panel and two side panels. Each secondary guide rail has an extended panel protruded from a side proximate to the primary guide rail. The top of each extended panel is not lower than the bottom of the side panel, and the slide element is sheathed onto the exterior of the guide rail, and a nut secured to the guide screw is formed in each guide rail. | 10-09-2008 |
20080295625 | Supporting Structure of Ball Screw Shaft - A ball screw shaft supporting structure of a ball screw rotationally supported by a housing via supporting bearings has a screw shaft formed, on its outer circumference, with a fitting portion and a positioning shoulder. An inner ring of the supporting bearing is press fit onto the fitting portion via a predetermined interference. A steel spacer ring is fit onto the fitting portion from the outer side of the supporting bearing with the inner side of the inner ring abutted against the shoulder. A caulking portion is formed on the end of the fitting portion by plastically deforming the end of the fitting portion radially outward. The inner ring is axially immovably secured on the screw shaft by the caulking portion via, the spacer ring. | 12-04-2008 |
20090282935 | SPINDLE BEARING ARRANGEMENT FOR A LONGITUDINAL SEAT ADJUSTING GEAR - The invention relates to a spindle bearing arrangement for a longitudinal seat adjusting gear, which has a housing which can be attached by an attaching device on a vehicle-side component or on a seat component, whereby a spindle opening for guiding a spindle along a spindle opening axis runs through the housing and whereby an inner thread in the housing in the area of its spindle opening is formed to engage into a spindle run through in this manner, for shifting the housing and the spindle relative to each other along the spindle opening axis. The spindle bearing becomes advantageous in that the inner thread is formed in a spindle nut and the spindle nut is adjustably supported in the housing relative to the spindle opening axis. | 11-19-2009 |
20110167940 | ROTARY-TO-LINEAR MECHANISM HAVING AN ISOLATOR - A rotary-to-linear mechanism including an elongate linearly-moveable first member having a longitudinal first axis, and rotatably-moveable second and third members. The second member is rotatably disposed about the first member and defines a second axis about which it is rotatable. The third member encircles the first axis and is operatively engaged with the first member. The third member is disposed in a central cavity of the second member and has an axial surface superposing a second member interior surface, the superposed surfaces each defining one of a pair of corresponding grooves each encircling the first and second axes. | 07-14-2011 |
20110174100 | FEED SCREW MECHANISM - A feed screw mechanism includes a feed screw shaft connected to a drive source and formed with first screw threads on an outer circumferential surface thereof, and a displacement nut, which is screw-engaged with respect to the feed screw shaft through a plurality of balls. The displacement nut is supported with respect to a slider that makes up an electric actuator by a pair of pins. The pins are inserted and fixed in first pin holes formed in the slider, and distal end portions of the pins are inserted respectively into second pin holes formed in the displacement nut. | 07-21-2011 |
20150122062 | ACTUATOR - An actuator includes M supports to support the rotary shaft, M being an integer equal to or more than 2; and M speed reducers. The Nth support out of the M supports is located at the opposite side of the moving body across the (N−1)th support, N being an integer which is equal to or more than 2 and equal to or less than M. The first speed reducer is connected to the moving body and the first support, receives a movement of the moving body in the axial direction as an input and drives the first support with a reduced drive force that is reduced from the input, and the Nth speed reducer is connected to the (N−1)th support and the Nth support, receives a movement of the (N−1)th support in the axial direction as an input and drives the Nth support with a reduced drive force. | 05-07-2015 |
