Abstract
A recirculating ball gear, in particular for a steering system of a motor vehicle, comprises a nut, which is mounted in a housing by way of a bearing, wherein at least one spring element is disposed on each end face of the bearing between the bearing and the housing. During operation, the recirculating ball gear is exposed to impact in the axial direction, whereby the gear may become damaged over time and annoying rattling noise may develop in the recirculating ball gear. The spring elements are thus operated in the progressive area of characteristic curve.
