Abstract：Based on special requirements of modern advanced automobile electric power steering(EPS)for steering transmission,the nylon helical gear steel worm transmission with stable transmission,low noise and low cost has been widely used.However,due to its special material,the traditional design method of worm gears is not applicable.In this study,by analyzing the special situation of the nylon helical gear steel worm transmis-sion,considering some factors such as performance,structure and cost,structural parameters and safety factors of the helical gear worm transmission mechanism under given conditions are designed and analyzed by Kisssoft software.According to the principle of easy processing,no failure and equal strength,the value of reasonable modification coefficient and the design method of each parameter of helical gear are put forward,and the model is simulated and verified by Workbench software.The results show that the optimized nylon helical gear steel worm transmission meets the design requirements and has better comprehensive performance.
