철로부터 고주파 경화된 토오크 전달 축을 형성하는 방법How to form a high frequency hardened torque transmission shaft from iron

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

유일한 도면은 본 발명에 따라 철로부터 고주파 경화된 토오크 전달 축을 형성하는 방법에 관련되는 단계들의 흐름도이다.The only figure is a flow chart of the steps involved in a method of forming a high frequency hardened torque transmission axis from iron in accordance with the present invention.

Claims (5)

(a) 소정의 미세구조를 갖는 철로부터 경화되지 않은 축을 형성시키는 단계; 및 (b) 결과의 철 축의 표면 및 외부 영역은 경화되고, 반면에 축의 내부 영역은 상대적으로 경화되지 않은 채로 남도록 경화되지 않은 축의 표면 및 외부 영역을 경화시키는 단계로 구성되는, 철로부터 고주파 경화된 토오크 전달 축을 형성하는 방법.(a) forming an uncured axis from iron having a predetermined microstructure; And (b) hardening the surface and outer regions of the resulting iron shaft while curing the surface and outer regions of the uncured shaft so that the inner regions of the shaft remain relatively uncured. How to form a torque transmission axis. 제1항에 있어서, 상기 단계 (a)가 철을 용융될때까지 가열하고, 용융철에 합금 물질을 첨가하고, 합금 철을 축의 일반적인 형태를 갖는 금형내에서 주조하고, 경화되지 않은 축을 형서하기 위해 주조 합금 철을 냉각시킴으로써 수행되는 방법.2. The method of claim 1 wherein step (a) heats iron until molten, adds alloying material to molten iron, casts alloy iron in a mold having the general shape of the shaft, and molds the uncured shaft. Method performed by cooling the cast alloy iron. 제1항에 있어서, 상기 단계(a)가 철 물질이 퍼얼라이트 미세구조를 갖도록 하는 방법.The method of claim 1 wherein step (a) causes the iron material to have a pearlite microstructure. 제1항에 있어서, 상기 단계(a)가 경화되지 않은 축을 기계가공하는 단계를 포함하는 것을 특징으로 하는 방법.The method of claim 1 wherein step (a) comprises machining an unhardened shaft. 제1항에 있어서, 상기 단계(b)가 고주파 가열에 의해 수행되는 방법.The method of claim 1, wherein step (b) is performed by high frequency heating. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
