Abstract

본 발명은 종래의 체인 스프로켓의 제조에 있어서 SCM강의 구득비용과 전체 중량 에대한 부담 및 기계가공의 곤란에 따른 생산비용의 상승이라는 문제점과 침탄법에 의한 표면경화에 있어서 침탄제의 소모량이 크고 침탄을 위한 가열에 소모되는 비용의 다대 및 침탄 후 제품과 잔류 침탄제의 처리에 대한 문제점을 개선하기 위하여 안출된 것으로서, 자동차 엔진의 체인 스프로켓의 재질을 소결합금으로하여 분말야금법으로 제조한 후, 치형 부분을 고주파 열처리함으로써 제조원가의 절감은 물론 제품의 경량화와 소음감소의 효과를 주는 자동차 엔진의 체인 스프로켓과 그 제조방법을 제공함을 목적으로 하며, 그 기술적 수단으로서 본 발명은 자동차 엔진의 체인 스프로컷(10)을 제조함에 있어서; SMF404M의 재질의 분말 또는 압분체를 금형성형 후 소결하는 분말야금법으로 제조한 다음, 상기 체인 스프로컷(10)의 외주면 치형 부분(20)의 첨단부(40)에 고주파 유도 경화법을 시행한 것을 특징으로 한다.The present invention has a problem in that the production cost due to the acquisition cost and overall weight of SCM steel and the difficulty of machining in the manufacture of a conventional chain sprocket and the consumption of carburizing agent in the surface hardening by carburizing method is large and carburizing It was devised to improve the problem of the cost of heating and carburizing the product and residual carburizing agent, and manufactured by powder metallurgy with the material of chain sprocket of automobile engine as a small alloy, It is an object of the present invention to provide a chain sprocket of an automobile engine and a method of manufacturing the same, which reduce the manufacturing cost by reducing the manufacturing cost by reducing the cost of the product by high-frequency heat treatment of the teeth, and as a technical means, the present invention provides a chain sprocket of an automobile engine. In making the cut 10; The powder or green compact of SMF404M is manufactured by powder metallurgy, which is sintered after mold molding, and then a high frequency induction hardening method is applied to the tip portion 40 of the tooth 20 of the outer peripheral surface of the chain sprocket 10. It is characterized by one.
