<p>Improved system for the automatic recovery of play between a worm (18) and worm wheel (16), constituted by one or more elastic elements (55) of the cup spring type or the like, acting normally to the axis of rotation of the worm (18). The system is advantageously used in working devices, particularly welding robots, or as a general universal manipulator and in all cases where exact cyclic repetitive positioning is required.</p> |
