Abstract
A nut unit (20) for use in a ball screw drive comprises a sleeve-shaped nut body (10) that is made of an essentially rigid material and that has an axis (A) and an inner circumferential surface (14). A one-piece, channel-shaped, ball-guiding strip material helix (18) is arranged on the inner circumferential surface (14) of the nut body (10). The strip material helix (18) is mounted within a concavely-curved support groove (16) formed in the inner circumferential surface (14) of the nut body (10). The helix (18) has an external convexly-curved profile (46), which is embodied with external profile flank regions (46') and an external profile crown region (46'). The helix (18) defines, by means of a curved internal profile (48) facing the axis (A), a ball channel with an internal profile base region (48') and two internal profile flank regions (48'). The outer profile flank regions are essentially rigidly supported by the support profile of the support groove (16).
