The Parametric Optimization and Test of the Reducer Worm Gear Mechanism of Electric Power Steering

The reducer worm gear mechanism is widely used in electric power steering. It has been optimally designed for the worm gear mechanism with the goal of the minimum volume of worm gear ring,saving precious materials 15. 05% compared with traditional design. The failure moment of the worm gear can be born is estimated by using simple calculation tool,and validated by experiments. The results show that the design optimization can meet the requirements of actual use.
