Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 歯部を高強度として信頼性が向上し、高減衰 能として運転時の騒音を低下し、また適切な幅にして所 定空間に納めることができ、自動車用デーゼルエンジン のタイミングギヤに適用できる複合歯車を得る。 【解決手段】 歯部を鋼材とし、ボス部を片状黒鉛鋳鉄 材、バーミキュラ鋳鉄材、または球状黒鉛鋳鉄材の何れ かよりなる高減衰能材とし、歯部とボス部とを摩擦圧接 して、摩擦圧接部の主要部を軸方向断面視で略平行また はテーパとする。 (57) [Summary] [Problems] To improve the reliability by increasing the strength of the teeth, to reduce the noise during driving due to the high damping capacity, and to be able to fit in a predetermined space with an appropriate width. A composite gear applicable to an engine timing gear is obtained. SOLUTION: The tooth portion is made of steel, the boss portion is made of a high damping material made of any of flaky graphite cast iron material, vermicular cast iron material or spheroidal graphite cast iron material, and the tooth portion and the boss portion are friction-welded. The main part of the friction welding portion is substantially parallel or tapered in a sectional view in the axial direction.
