Abstract
A helical gear mechanism for a steering system in a motor vehicle comprises a helical pinion which engages with a helical gear and a bearing bushing which accommodates a bearing of the helical pinion. An inner ring of the bearing bushing is connected to an outer ring via a pivot bearing so that a pivoting motion of the helical pinion relative to the helical gear is possible. A pressure piece is disposed between the inner ring and the outer ring of the bearing bushing. The pressure piece is movable in a spring-loaded manner in a section of an annular gap between the inner ring and the outer ring. The inner ring and/or the outer ring are designed in the section so that the annular gap between the inner ring and the outer ring is tapered in the direction in which the pressure piece can be moved in a spring-loaded manner.
