Patent number: 7476032Abstract: A guide rail (12) of a linear guide unit (10) is provided with at least one running rail (16), which has at least two races (16a) that have different load transmission directions. According to the present invention, the running rail (16) is attached to the guide rail (12) by means of roller insertion; in the surface sections (12a) associated with the races (16a) of the running rail (16), the guide rail (12) is provided with a plurality supporting ribs (12a1); and the supporting ribs (12a1) associated with one and the same race (16a) are aligned essentially parallel to the load transmission direction (B) of this race (16a). In addition or alternatively, in a section (12d) that is not intrinsically deformed by the roller insertion of the at least one running rail (16), the guide rail (12) has at least one additional rolled section. The present invention also relates to a method for manufacturing guide rails of this kind (12).Type: GrantFiled: July 25, 2007Date of Patent: January 13, 2009Assignee: Rexroth Star GmbHInventors: Wolfgang Kuellstaedt, Richard Kuehnlein, Thomas Wahler, Roland Greubel, German Duetsch, Werner Keller, Stefan Dorn, Steven Worcester, Werner Blaurock

Patent number: 6698301Abstract: A screw drive with rolling elements, optionally a ball screw drive, includes a screw spindle with a spindle axis and a double nut running on the screw spindle, with two separately formed single nuts which are substantially rigidly joined in the direction of the axis of the spindle. In order to set a desired play or bias relative to the screw spindle, the two single nuts can be turned continuously about the axis of the spindle relative to each other and fixed in any relative rotary position corresponding to the desired play or bias. According to the invention, a first of the two single nuts or an intermediate element joined thereto and arranged between the two single nuts has at least one peripheral section pressed into an associated aperture in one of the single nuts. In one embodiment, the intermediate element is an annular disk that is arranged orthogonally to the spindle axis.Type: GrantFiled: October 17, 2001Date of Patent: March 2, 2004Assignee: Rexroth Star GmbHInventors: Werner Blaurock, Roland Greubel, Hugo Och, Peter Blattner, Erich Huppman

Patent number: 6484599Abstract: A nut unit (20) for use in a ball screw drive comprises a sleeve-shaped nut body (10) that is made of an essentially rigid material and that has an axis (A) and an inner circumferential surface (14). A one-piece, channel-shaped, ball-guiding strip material helix (18) is arranged on the inner circumferential surface (14) of the nut body (10). The strip material helix (18) is mounted within a concavely-curved support groove (16) formed in the inner circumferential surface (14) of the nut body (10). The helix (18) has an external convexly-curved profile (46), which is embodied with external profile flank regions (46′) and an external profile crown region (46″). The helix (18) defines, by means of a curved internal profile (48) facing the axis (A), a ball channel with an internal profile base region (48″) and two internal profile flank regions (48′). The outer profile flank regions are essentially rigidly supported by the support profile of the support groove (16).Type: GrantFiled: January 26, 2001Date of Patent: November 26, 2002Assignee: Rexroth Star GmbHInventor: Werner Blaurock

Patent number: 6321614Abstract: A screw drive (10a) with rolling elements, optionally a ball screw drive, includes a screw spindle with a spindle axis (S) and a double nut (14a) running on the screw spindle, with two separately formed single nuts (16a , 18a) which are substantially rigidly joined in the direction of the axis (S) of the spindle. In order to set a desired play or bias relative to the screw spindle, the two single nuts (16a, 18a) can be turned continuously about the axis (S) of the spindle relative to each other and fixed in any relative rotary position corresponding to the desired play or bias. According to the invention, a first of the two single nuts or an intermediate element (28a) joined thereto and arranged between the two single nuts, as a first alternative, is welded to one of the two single nuts or to at least one part (42a) joined thereto or, as a second alternative, has at least one peripheral section pressed into an associated aperture in one of the single nuts.Type: GrantFiled: December 28, 1999Date of Patent: November 27, 2001Assignee: Rexroth Star GmbHInventors: Werner Blaurock, Roland Greubel, Hugo Och, Peter Blattner

Patent number: 5868499Abstract: A linear guiding unit comprises a guide housing (10). Inside the guide housing (10) there are provided linear ball bearings by which a carriage (40) is guided. Moreover, a pneumatic drive (56) is accommodated within the guide housing (10). The pneumatic drive comprises a cylinder cavity (58) inside the guide housing (10). The cylinder cavity (58) accommodates a piston (60). The piston (60) is movable along the cylinder cavity (58). The piston (60) is connected with the carriage (40) by a flexible rope (74). This flexible rope is sealingly passed through cover walls (66) of the cylinder cavity (58). The rope is deviated outside the cylinder cavity (58) and is fixed to the carriage (40). A cover belt (90) different from the rope covers a longitudinal opening (31) of the guide housing (10) through which the carriage can be connected with an object for common axial movement.Type: GrantFiled: September 3, 1997Date of Patent: February 9, 1999Assignee: Deutsche Star GmbHInventors: Roland Greubel, Bernhard Keller, Werner Blaurock

Patent number: 5211483Abstract: Rolls of roller bearings have in their axial middle portion a load-transmitting peripheral surface and on their axial end portions there are respective radially projecting and space-maintaining peripheral surfaces. Therefore, only the space-maintaining peripheral surfaces of adjacent rolls contact one another.Type: GrantFiled: August 29, 1991Date of Patent: May 18, 1993Assignee: Deutsche Star GmbHInventor: Werner Blaurock

Patent number: 4564993Abstract: In a screw drive, in particular a ball screw drive, a double nut, formed of a pair of individual nuts, is tightened on a threaded spindle and the individual nuts are secured together against relative rotation by a locking member. The locking member is secured within a radially extending recess formed in and bridging the individual nuts. The locking member can be inserted with a certain amount of play into the recess or borehole and then secured within the recess by a cement or similar material so that it cannot be displaced. Various types of locking members can be used, such as locking bolts or threaded bolts. When the locking member is connected into the recess or ball it prevents any rotation of the individual nuts relative to one another.Type: GrantFiled: March 1, 1983Date of Patent: January 21, 1986Assignee: Deutsche Star Kugelhalter GmbHInventors: Gunter Blaurock, Ernst Albert, Werner Blaurock, Benno Peichl, Klaus Reichert, Hans-Georg Stender, Rudolf Schlereth
