Embodiment Construction

[0035] figure 1 An example of a spindle nut 1 screwed on a spindle 2 according to the invention is shown. The spindle nut comprises a first nut part 3 and a second nut part 4 each having a base unit which is substantially formed rotationally symmetrically with respect to the axis 14 of the spindle nut. Between the first nut part 3 and the second nut part 4 there is an intermediate part 8 which is pressed onto the second nut part 4 by means of a multi-wave spring washer 7 which on the one hand is aligned with the first nut The part 3 and on the other hand are aligned with the intermediate part 8 .

[0036] The structure of the spindle nut according to the present invention is achieved by figure 2 and an exploded view of 3 is shown in more detail. The first nut part 3 comprises a substantially hollow cylindrical protrusion 12 having an outer diameter smaller than the outer diameter of the first nut part itself. The multi-wave spring washer 7 is fastened on the protrusion 12...

Abstract

A backlash-free spindle nut is disclosed with a thread that can be meshed with a spindle. The spindle nut has a first nut part with a first internal thread and a second nut part with a second internal thread that can be twisted in relation to the first nut part. To generate a preload between the first nut part and the second nut part, the spindle nut has an elastic element. The preload can be adjusted through relative twisting between the first nut part and the second nut part. The elastic element can work between the first nut part and a secure intermediate part, whereby relative twisting between the first nut part and the second nut part can be locked by locking a relative twisting position between the second nut part and the intermediate part.

Description

technical field [0001] The invention relates to a backlash-free spindle nut. Background technique [0002] A universal type of backlash-free spindle nut has threads that engage the spindle. In addition, the spindle nut has a first nut part and a second nut part, the first nut part has a first internal thread, the second nut part has a second internal thread, the second nut part can be opposite to the first nut part twist. The first internal thread and the second internal thread jointly form the thread of the spindle nut. In order to generate a preload between the first nut part and the second nut part, an elastic element, such as a spring, is further provided. In a common type of spindle nut, the preload is adjustable by relative twisting between the first nut part and the second nut part. [0003] Backlash-free spindle nuts are known from the prior art. For example, DE 4 204 304 A1 shows a one-piece spindle nut, the central area of ​​which is itself formed as a spring,...
