HL5050G型联合收割机部分零件失效分析

Analysis of the Reason of Failure of Some Parts of the HL5050G Combine

分析了HL5050G联合收割机部分零件失效原因,滚筒主轴、小轴、齿轮的开裂及磨损主要是由于夹杂物含量太高、马氏体粗大、应力集中、带状组织及脱落所致。

In this article we analysis the failure of some parts of the HL5050G combine. The tearing and gear is caused by containing too many impurities, the martensitic marix - thickening,stress concentrating on the strip structure and decarbonization.
