Foundation of numerical analysis of worm gearing: interrelated variables of contacting tooth surfaces

摘要

In order to perform the numerical calculation of worm gearing engagement principles effectively, the interrelated variables of the contacting tooth surfaces of worm cutter and worm (ICW-Variable) and those of worm and wheel (IWW-Variables) are defined first. The relationship and value regions of ICW-Variables are discussed, end then the theory of worm tooth-surface-parameter network is presented. Based on the theory, the analysis of IWW-Variables is made and the method to determine their value regions is further proposed.
