摘要:
A spindle nut for a ball screw is provided, having a continuous ball track (1) for balls (2), a ball groove (3,14) for the balls (2) extending on an inner periphery of the spindle nut about the rotational axis thereof and along a helical line, the ball groove extending across at least one thread (4), and a diversion device (5), in order to divert with its diverting channel (9) balls (2) from one end of the thread (4) to the beginning of the thread (4). The spindle nut is provided with ball inlets (13, 16), on the one side connected to the ball groove (3, 14) and, on the other side connected to the diverting channel (9), with the ball groove (3, 14) and the ball inlet (13, 16) both having identical cross-sectional profiles.
