Abstract
A worm-gear has an electric motor, which drives a worm, which meshes with a worm-wheel. Hitherto both the motor shaft and the output shaft have been mounted in a housing which, for assembly reasons, only permits a sliding fit between the motor shaft and its bearings. In order to simplify the assembly and permit the desirable interference fit between the motor shaft and its bearings, provision is made for both bearings for the motor shaft to be arranged in a first housing part, which, when the shaft is installed, can be separated from and re-connected to a second housing part, in which two bearings for the output shaft are arranged.

A worm-gear comprising:
- an electric motor having a motor shaft connected to a worm, an output shaft connected to a worm-wheel which meshes with the worm, and a housing in which the motor shaft and the output shaft are each rotatably mounted in respective pairs of bearings, wherein the motor shaft, the worm and both bearings for the motor shaft are mounted in a first housing part of the housing forming a first separate unit, wherein the output shaft, the worm-wheel and both bearings for the output shaft are mounted in a second housing part forming a second separate unit, and wherein the first unit can be separated from and re-connected to the second unit in a radial direction to the motor shaft.
