英文摘要： Eliminating the negative effect of gear backlash on transmission precision so as to achieve precise motion transformation remains a problem to be solved in the field of precission transmission. This project originally proposes a type of transmission device, an anti-backlash planar enveloping end face engagement worm gear drive, with certain advantages of no-backlash, high precision and high operating efficiency over other gears and gear systems. Based on the theories of differential geometric and gear meshing, the project investigates the different meshing functions and their derivates with respect to each drive type. Also,this project analyzes the meshing characteristics of anti-backlash planar enveloping end face engagement worm gear drive in multivariable space and discusses the variation of the design variables of end face engagement worm,worm teeth,spring wedge-shaped mechanism et al., followed by the study of the relationship between load-carrying capacity and the variation of the end face parameters and the research of the influence of the machining and misalignment errors on the contact curves and the tooth profile. By doing so, a novel efficient manufacturing technology is proposed and used to minimize the effect of errors so as to design the most optimal tooth profile with high operating efficiency a
