Abstract

Means for transforming rotary movement of a spindle (1) that has helical threads (2) to axial movement of a nut (3) embracing the spindle (1), and conversely for transforming axial movement of the nut to rotary movement of the spindle, comprises elements which are disposed between the spindle (1) and the nut (3) and which lie along at least two mutually parallel and mutually spaced peripheral lines around the spindle (1). Respective elements are comprised of a crown roller (11) which forms, on the one hand, a roller body-part (12) and, on the other hand, a ball race (13). The roller body-part (12) is adapted to engage the threads (2) of the spindle, and the ball race (13) is positioned so as to face away from the axis of the spindle (1) and lie in a plane which extends perpendicular to and has its rotational centre in a line passing through the spindle axis and the centre of the spherical part (12). Bearing balls (15) are disposed between the ball race (13) and the nut (3), and two mutually adjacent crown rollers (11) engage with mutually proximal or mutually distal thread flanks of the thread (2) or the threads.
