알루미늄 합금 변속 레버 부싱

수명 요구 사항은 부품이 폐기되지 않고 예상 작업 기간 동안 정상적인 작동을 유지하도록 요구하는 것입니다. 이 요구 사항은 주로 다양한 스트레스를 받고 작업하는 동안 마모되거나 부식되는 부품에 적용됩니다.

As the main factors affecting the fatigue limit of parts and materials are stress concentration, size, surface quality and environmental conditions, the main measures to improve the life of parts are: ① properly involving the structure of the part to reduce the degree of stress concentration; ② using processing or surface strengthening treatment Improve the quality of the working surface of the parts; ③ Reasonably choose the friction pairing materials, lubricants and lubrication methods to improve the wear resistance of the parts; ④ Choose corrosion-resistant materials to make parts that work in corrosive media; ⑤ Use heat treatment to improve the mechanical parts of the parts Performance, or use rolling, shot peening and other processes to generate favorable residual stress on the surface of the part, etc.
