Title: Electric power steering device
Inventor: CHIKARAISHI KAZUO
IPC: B62D5/04
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide an electric power steering device capable of reducing hammering noise while maintaining accuracy of a worm. SOLUTION: Tooth flank abrasion of the worm 30a is suppressed by applying electroless plating process on at least a tooth flank of the worm 30a for improving tooth flank strength of the worm 30a meshed with a worm wheel 13 even when a resin including glass fiber or the like is used for the worm wheel 13. By employing the electroless plating process, it is possible to provide a uniform plating film thickness and to accurately reproduce a basis material shape for easily securing gear accuracy of the worm 30a. Because the worm 30a is substantially not subjected to heat treatment after tooth flank forming, problems of accuracy degradation due to thermal deformation do not occur and deterioration of surface roughness of the tooth flank is prevented, and thereby slip loss occurring between the worm 30a and the worm wheel 13 during power transmission can be reduced. Thus, transmission efficiency can be improved.
