Research overview of anti-backlash end face engagement worm gearing

Abstract

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 precision transmission. To date, optimization of manufacturing process, new transmission structure and control system are mainly used to solve the above scientific problem, however, the new transmission structure is undoubtedly the best method compared with the methods above based on the analysis of advantages and disadvantages for various methods. In doing so, this paper originally proposes a type of transmission, an anti-backlash end face engagement worm gearing, with certain advantages of no-backlash, high precision and high operating efficiency over other gears and gear systems.
