ウォームホイール及びその製造方法

Worm wheel and its manufacturing method

Abstract

(57)【要約】 【課題】金属芯金と樹脂リングギヤとの固着力を確保し つつ、電動式パワーステアリング装置の設計の自由度を 向上できるウォームホイール及びその製造方法を提供す る。 【解決手段】芯金31を鍛造加工によって深皿状とし且 つ同時に外周凹凸部31eを形成することができるた め、任意の形状を形成しつつ十分な強度を有しながらも 軽量化を達成できる。又、単品のリングギヤ32と単品 の芯金31との間に接着剤を介在させつつ外周凹凸部3 1eと内周凹凸部32bとを係合させた後、高周波溶着 によって結合させることにより、芯金31とリングギヤ 32との固着力を確保することができる。
PROBLEM TO BE SOLVED: To provide a worm wheel and its manufacturing method that can improve designing freedom of an electric power steering device while securing fixing force between a metal core bar and a resin ring gear. SOLUTION: The worm wheel has any shape and a sufficient strength and can be lightened, because the core bar 31 is casted dish-like and simultaneously can have an outer peripheral projecting/recessed part 31e. The outer peripheral projecting/recessed part 31e is jointed to an inner peripheral projecting/recessed part 32b while an adhesive is interposed between the single ring gear 32 and the single core bar 31, then they are jointed by high frequency welding, and thereby the fixing force between the core bar 31 and the ring gear 32 can be secured.
