摘要:
The invention relates to a threaded drive consisting of a threaded axle (1), a screw nut (2) and rolling bodies. When said threaded drive is subjected to a high static load, the forces are transmitted from the threaded axle (1) to the screw nut (2) by means of the rolling body. As the contact surfaces between the rolling bodies, the screw nut (2) and the threaded axle (1) are very small, only relatively weak forces can be transmitted. In order to adapt the threaded drive to high static loads, using simple construction measures, the surface of the threaded axle (1) between the grooves (4) of the rolling bodies is provided with locking forms which can be positively connected with complementary locking forms of locking elements (7, 8) which can be essentially transversally displaced in relation to the axis of the threaded axle (1).
