Abstract
A worm gear has a worm wheel, a drive shaft, and a flexible shaft. The worm wheel meshes with a worm shaft, which is driven by the drive shaft. The flexible shaft can be arranged in the drive shaft with a radial gap between at least a portion of the flexible shaft and the drive shaft. The flexible shaft can be coupled to the drive shaft such that a first spring constant is provided for displacement of the flexible shaft in a radial direction within a first range and a second spring constant is provided for displacement of the flexible shaft in the radial direction within a second range.
