A drive mechanism with micrometric controller that is arranged as drive and driven shafts with drive and driven discs pressed by compression spring, at right end of drive disc at outer diameter uniformly in circle spherical depressions are provided, there balls are installed, with smooth approach, those at the other end are in interaction with spherical depressions in similar form, those have smooth approach in zone of transport track of driven disc, there balls roll in mode of overload, this is rigidly fixed to the driven shaft, at that at the right end of the drive shaft slots are provided, there rigidly, with possibility of axial displacement, drive disc is installed, its right end is in interaction with the left end of the driven disc, at the right end of the drive shaft on slots compression spring is installed, this with the left end is in interaction with the end of the nut that is turned on to thread surface that is provided on slots of drive shaft, and with left end is in interaction with lock-nut and limb, this is in interaction with nonius applied to cylindrical smooth surface of drive shaft, besides that axial motion of drive disc at the end of drive shaft is restricted by lug of screw that is turned in to the end of the shaft. |
