SPINDLE DRIVE

摘要

The invention relates to a spindle drive for converting between a rotational motion and a translational motion comprising a spindle for translational motion and a spindle nut for rotational motion, wherein the spindle and the spindle nut are coupled to each other by means of threads. The spindle nut comprises a reservoir in axial extension of the thread of the spindle nut, in which reservoir a segment of the spindle extends. A lubricant is accommodated in the reservoir, and a displacement element is attached to the spindle in the region of the reservoir, which displacement element extends further outward radially than the thread of the spindle.

1. A spindle drive (100) for converting between a rotational motion and a translational motion, comprising:
a spindle (105); a spindle nut (115); wherein the spindle (105) and the spindle nut (115) are coupled to each other by a thread (110) of the spindle and a thread (120) of the spindle nut, wherein the spindle nut (115) comprises a reservoir (150) in axial extension of the thread (120) of said spindle nut, in which reservoir a segment of the spindle (105) extends, wherein a lubricant (155) is accommodated in the reservoir (150), characterized by a displacement element (165) attached to the spindle (105) in a region of the reservoir (150), which displacement element extends further outward radially than the thread (110) of the spindle (105).
