A worm gearing in which as worm drive shaft is used, with screw surface welded to it, at that cross section of screw surface has form of equilateral trapezium, like cross section of screw turn, with larger basis fixed to drive shaft with number of starts, for instance, 1…4, this with its free ends is installed to supports with possibility of circular turn, and toothed wheel is arranged as two installed in parallel cylindrical flanges in space between which uniformly in periphery of circle cylindrical pins of type of teeth are installed to bushings, those are in interaction with working surfaces of screw surface with possibility of circular turn, besides that the flanges are rigidly connected to each other with bolts on which thrust springs are installed, at that the bolts are rigidly installed in parallel to drive shaft with possibility of axial displacement and fixed with known method, besides that the heads of the bolts are tightened with wire through openings in heads, its ends are rigidly connected to each other. |
