Screw shaft and manufacturing process for a screw shaft

Abstract

The present invention relates to a worm shaft (12) with at least one toothed section (14) winding around a worm shaft rotation axis (16) of the worm shaft (12), which is shaped along its entire length such that for each partial section of the at least one toothed section (14) a cross-sectional area (22) can be defined with a cross-sectional plane (20) intersecting the respective partial section and encompassing the worm shaft rotation axis (16), through which a straight line (24) oriented perpendicular to the worm shaft rotation axis (16) passes centrally, wherein the at least one toothed section (14) of the worm shaft (12) has a variable tip circle diameter and / or a variable tip height along its respective length. The present invention also relates to a worm gear and a device equipped with a worm gear.Furthermore, the invention relates to a manufacturing method for a worm shaft, a manufacturing method for a worm gear and a manufacturing method for a device equipped with a worm gear.
