Abstract: A method for producing a threaded nut (10, 26) of a screw drive, in particular of a ball screw (7, 24), which threaded nut (10, 26) has, on one axial end, a recess (45) which extends over a circumferential segment and which is open at the end side, wherein said recess (45) is delimited radially by a circumferential wall of the threaded nut (10, 26), and wherein said recess (45) is delimited axially by a base (54) formed on the threaded nut (10, 26), and wherein said recess (45) is delimited in the circumferential direction by a stop surface (47), which is formed on the threaded nut (10, 26), for a projection (44), produced according to the following steps: a blank is deformed in a deformation process by deformation of material so as to form the recess (45), wherein the base (54) and the stop surface (47) and the circumferential wall are integrally connected to one another.

Abstract: A ball screw (7, 24), having a threaded spindle (8, 28) which is mounted in a rolling fashion by balls (9, 27) on a threaded nut (10, 26) and which is supported on an axial bearing (13, 25), wherein the threaded spindle (8, 28) is axially supported with its first bearing surface (18, 23), which is convexly shaped with a radius of curvature (R1), on a preferably conically designed second bearing surface (19, 22), wherein the first bearing surface (18, 23) and the second bearing surface (19, 22) make contact with one another along a contact path (37), wherein a quotient formed from the ratio of the radius of curvature (R1) to the radius (R2) of the contact path (37) assumes values of between 1.2 and 2.4 inclusive.

Abstract: A ball screw (7, 24), having a threaded nut (10, 26) which is arranged on a threaded spindle (8, 28) and having a stop (43) for the circumferential abutment of the threaded nut (10, 26) in its stop position provided on the threaded spindle (8, 28), wherein the stop (43) has a first stop surface (47) assigned to the threaded nut (10, 26) and has a second stop surface (48) which is provided for abutting against the first stop surface (47) and which is assigned to the threaded spindle (8, 28), and, in the stop position, an axial overlap of the first stop surface (47) with the second stop surface (48) is provided, which overlap amounts to between 20% and 85% of the pitch of the threaded spindle (8, 28).

Abstract: A ball screw (7, 24), having a threaded nut (10, 26) which is arranged on a threaded spindle (2, 28) and having a circumferential stop (43) which is arranged between the threaded spindle (2, 28) and the threaded nut (10, 26) and which takes effect in a stop position of the threaded nut (10, 26), wherein a stop part (51) is arranged on the threaded spindle (8, 28), wherein the stop part (51) and the threaded nut (10, 26) are provided in each case with a marking (49, 50) for determining a rotational position of the stop part (51) in which the stop part (51) should be arranged on the threaded spindle (8, 28).

Abstract: A ball screw (7, 24), having a threaded spindle (8, 28) which is mounted in a rolling fashion by balls (9, 27) on a threaded nut (10, 26) and which is supported on an axial bearing (13, 25), wherein the threaded spindle (8, 28) is axially supported with its first bearing surface (18, 23), which is convexly shaped with a radius of curvature (R1), on a preferably conically designed second bearing surface (19, 22), wherein the first bearing surface (18, 23) and the second bearing surface (19, 22) make contact with one another along a contact path (37), wherein a quotient formed from the ratio of the radius of curvature (R1) to the radius (R2) of the contact path (37) assumes values of between 1.2 and 2.4 inclusive.

Abstract: A ball-screw drive, which has a spindle nut arranged on a threaded spindle and an axial bearing which is arranged so as to act on the threaded spindle and which has a bearing part arranged so as to be rotatable relative to the threaded spindle. The bearing part is arranged so as to be captively retained on the threaded spindle by a captive retention means.

Abstract: A tensioning device for traction means, especially for toothed belts, is provided with a tensioning arm (3) on which a tensioning roller (1) is rotatably arranged. Furthermore a stopper (12) is provided which restricts a swiveling angle of the tensioning arm (3), whereby a detachable locking device (15) is provided through which the tensioning arm (30) and the stopper (12) are locked for joint swiveling into a position provided for the stopper (12).
