Abstract
The invention relates to an electromechanical steering system having an electric servomotor (1) which drives a worm shaft (2) which meshes with a worm gear (7) which is arranged on a steering shaft (8), wherein the worm gear (7) is operatively connected to an input shaft of a steering gear, and wherein the worm shaft (2) and the steering shaft (8) are mounted rotatably in a common gearbox casing (9), in which the worm shaft (2) has a free end (12) which is remote from the motor and is mounted in a rolling bearing (13) with an inner ring (14), rolling bodies (15) and an intermediate ring (16), wherein the intermediate ring has an inner running surface for the rolling bodies (15) and an outer running surface for outer rolling bodies (17), and wherein the inner running surface and the outer running surface of the intermediate ring (16) are arranged eccentrically with respect to one another.
