Abstract
The invention relates to a lead screw drive (10) and a spindle nut (12) for converting a rotational movement into a longitudinal movement or vice versa, wherein the internal thread (20) of the spindle nut and the external thread (30) of the spindle are of asymmetrical configuration with respect to one another. At least the internal thread (20) of the spindle nut or the entire spindle nut (12) is manufactured from plastic. The external thread (30) of the spindle has a higher strength. It is provided according to the invention that the internal thread (20) of the spindle nut (12) has a thread cross section, in which that profile section face (S1) of the thread spiral (21) which is intended for engagement into the thread (32) of the spindle (11) is greater, in particular is greater by a factor of at least 1.2, than the free thread section face (S2) of the thread (22) of the spindle nut (12).
