An electromechanical power steering system having an electric servo motor having a motor shaft. The electric servo motor drives a shaft which meshes with a helical wheel. The shaft is rotatably supported in a gear mechanism housing. The motor shaft is coupled to the shaft in a rotationally secure manner by a coupling which compensates for an axial offset. The shaft at the end thereof close to the motor is supported in a bearing in the gear mechanism housing so as to be able to be rotated about a rotation axis and is pivotably supported about a pivot axis which is perpendicular to the rotation axis in such a manner that the pivot axis is arranged in the region of the coupling.

A helical gear transmission for an electromechanical servo steering mechanism may include a shaft that meshes with a helical gear. The shaft may be arranged in a transmission housing and, at its first end, may be mounted in a drive-side bearing arrangement so as to be rotatable about an axis of rotation. At its second end, the shaft may be mounted in a drive-remote bearing arrangement in the transmission housing. The drive-side bearing arrangement may have a rolling bearing, an outer ring of which is spherical. The rolling bearing may be enclosed by two bearing shells. The outer side of the outer ring may have two flat points that are opposite one another and form a pivot axis about which the shaft is pivotable in a direction of the helical gear.

In a first rotation position between the housing parts, the gear without the additional gearwheel may connect the input shaft with the output shaft with a first transmission ratio. In a second rotation position different from the first rotation position, between the housing parts, the gear with the additional gearwheel may connect the input and output shafts with a second transmission ratio different from the first transmission ratio.

An electromotive furniture drive includes a housing having an opening, a drive motor attached to the housing and including an output shaft, and a standpipe inserted into the housing laterally in a form-fitting manner. The standpipe has an outer wall formed with a transverse groove, with a lifting spindle arranged in the standpipe.
