Analogs of Axes of Meshing in General Type Worm Gearing

摘要

The paper describes the meshing space for worm gears with general type worms, including double-enveloping and bevel worms. A pair of conjugate lines is revealed in this space. Position of these lines is defined by position of surface of movement of the cutting edge which generates a worm but does not depend on this edge profile. The revealed lines are pre-assigned to belong to the meshing surface and, in this respect, they are similar to the axes of meshing of gears with a cylindrical worm. Applying the properties of the pointed lines allows, to some extent, for simplification of the analysis of the known and synthesis of new types of worm gears.
