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.
Claims18
A backlash-free spindle nut with a thread which can be meshed with a spindle, the spindle nut comprising:
- a first nut part with a first internal thread;
- and
- a second nut part, separate from the first nut part and twistable in relation to the first nut part, with a second internal thread, whereby the first internal thread and the second internal thread together form the thread of the spindle nut;
- an elastic element to generate a preload between the first nut part and the second nut part, the preload being adjustable through relative twisting between the first nut part and the second nut part;
- and
- an intermediate part that is separate from the first part and second nut part and is secured against twisting in relation to the first nut part, whereby the elastic element is positioned to work between the first nut part and the intermediate part, and 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.
