Based on the principle of line contact conjugation of enveloping worm indexing cam mechanism and focusing on the transmission ratio, backlash-free and orthogonal cross-axis drive characteristics of this kind of mechanism, the point meshing theory of media conjugate indexing cam mechanism is emphatically studied The technical scheme of point meshing and asynchronous meshing is put forward. The basic equation of mesh conjugation, the contact trace equation, the induced principal curvature and the calculation formula of contact area are given The engineering experience of maturity to the theoretical level of research and further analysis and manufacturing research, laid a solid foundation
