Abstract
A rolling-member worm-drive (10) comprises a spindle and a nut element (12) surrounding the spindle, where the spindle and the nut element (12) between them establish a helical rolling-member screw path, where in addition this rolling-member screw path is completed by an axial rolling-member return path, contained in the nut member, to a closed rolling-member circulation path in which an endless row of rolling-members travels, where in addition two rolling-member diverting elements (26) are arranged on the nut element (12) for transfer of the rolling-members between the rolling-member screw path and the rolling-member return path and between the rolling-member return path and the rolling-member screw path, and where at least one of the rolling-member diverting elements (26) is held on the nut member (12) by means of a securing element (36). In the rolling-member worm-drive according to the invention, the securing element is a securing ring (36) designed physically separate from the rolling-member diverting element (26).
