KINEMATIC STRUCTURE OF MACHINES WITH ELECTRONIC SYSTEM TIMING DRIVE FOR CUTTING A TWO STEP CHERVYAKOV

Abstract

Design features of the two-step worm to ensure his pairing with the traditional one-step worm gear It is shown that such worm raznoshagovost replacement due cylindrical primary coil of the conical surface. Provides a method of cutting a worm called the cup cutter in the form of gear tooth profile, whose shape is complementary with rounding profile thread being cut worm. Developed on the basis of specialized machines with mechanical constraints for tapping the cup cutter worms kinematic structure of the machine with variable speed drives individual executive. A variant of the synchronization variable speed drives on the basis of standard integrated circuits.
