A plain bearing of a shaft, in particular of an electric-motor drive unit of a motor vehicle, contains a first plain bearing part that surrounds the shaft and a second plain bearing part connected axially to the first plain bearing part. The thermal expansion coefficient of the second plain bearing part is greater than the thermal expansion coefficient of the first plain bearing part.

Plain bearing

The invention relates to an arrangement for acoustic decoupling of a stator of an electric motor having two substantially cylindrical decoupling rings disposed on both sides of the stator and concentric to a motor shaft, each fixed to a front side of the stator on one side and each fixed to a housing enclosing the stator on the other side, and comprising recesses on the circumferential surfaces thereof. The decoupling rings hold the stator in a centered position at a distance from the housing. The recesses allow targeted acoustic decoupling. The invention is particularly applicable for electric motors in steering systems for motor vehicles.
