Abstract: A ball screw drive having a threaded spindle and a spindle nut enclosing the spindle coaxially. At least two radially outwardly open channels are oriented axially in parallel and are simultaneously pressed into the lateral surface, the channels open toward a common front face of the spindle nut. Balls circulate in a helical ball race in the space between the spindle and the nut. A ball return guide has two ball deflectors and a transfer channel running therebetween. A drive element is operatively connected coaxially to the spindle nut and applies a torque onto the spindle nut. The operative connection between the drive element and the spindle nut is formed by a contact surface with a connecting contour and a driver element (designed such that in the assembled state it engages in one of the channels. The ball screw drive can be used as an actuating element.

Abstract: A ball screw drive includes a threaded spindle and a spindle nut with a plurality of balls that circulate endlessly in the intermediate space between the nut and the spindle. A ball return guide guides balls at one location out of the helical ball race by a ball deflector and feeds the balls back via a transition channel and another ball deflector. The ball deflectors are arranged in radial through-openings in the lateral surface of the nut. One or more small metal plates are provided on the nut, and are arranged in and/or adjacent to the radial through-openings and offset inwardly away from the lateral surface, and span the ball return guide in a planar manner. The ball return guide is fixed in a target position in the lateral surface of the nut, and when fully assembled the small metal plates do not protrude beyond the lateral surface.
