This study is making a product for the development of a process worm wheel of making a shape for gear for worm wheel without hobbing manufacturing process. Because of removing a hobbing process, plastic worm wheel for increased productivity and equivalent quality is produced in this molding. As the result, CAE manufacturing process for a EPS worm wheel of small and middle stage cars and hybrid vehicle is developed. Especially, the considerations for analysis results of worm wheel are as follows. the first, CAE analysis for worm wheel of first stage is considered. the second, CAE analysis for boss is considered. the third, CAE analysis for gear module strength of first stage is considered. Finally, the redesign of product drawings for troubled-considered in first stage try-out is considered in EPS worm wheel.
