ABSTRACT:
In a device for fixing a ball screw
ut mechanism, including a ball screw and a ball nut, safe from turning. The ball screw
ut mechanism generates a linear movement to displace a first subassembly until it rests on a second subassembly. A blocking device is provided, which is adapted to fix the rotating part of the ball screw
ut mechanism, when both subassemblies are in contact, safe from turning through a reaction force originated by an external force and by overcoming the force of a first resetting means. When the parts are in contact, the blocking device is positioned in a determined distance from the first subassembly, and when the external force, generated by the drive device, arises the turnable part is safe from turning, until the determined distance between the first subassembly and the blocking device is compensated for.
