See full text

The invention relates to a ball screw (10) with a threaded spindle (12), a nut (14), rolling bodies (16) and at least one deflecting device (18, 20), wherein the threaded spindle (12) is displaceable by rotation, and wherein the deflecting device comprises an inner first body part (18) and an outer second body part (20), which body parts together form a deflecting channel (22), wherein the deflecting channel (22) has two tubular ends (24, 26) which are connected to each other via a transfer region (28), wherein the tubular ends (24, 26) of the deflecting channel are in each case formed by mutually complementary partial tubular sections (30, 32, 34, 36) of the body parts (18, 20), and wherein a sleeve (40) surrounding the nut (14) is provided, the deflecting device (18, 20) sits in an opening (42) in the nut (14), the deflecting device (18, 20) projects radially beyond the outer lateral surface of the nut (14) in a relaxed state when the sleeve (40) is absent and, in the presence of the sleeve (40), said sleeve exerts a radially inwardly directed force on the deflecting device (18, 20).
