1982年,我场引进15台 C—12M 型联合收割机。在83年麦收中,其中有3台最终传动装置发生打齿故障。针对最终传动装置打齿这一故障,我们除对打齿的原因进行分析外,还对其余12台进行了检查,发现大、小减速齿轮都有不同程度的异常损坏。普遍存在着齿面淬硬层脱落和啮合印痕偏斜现象。为此,我们对该机型最终传动装置的结构特点、使用、调整及保养进行分析并提出预防的措施。 In 1982, I introduced 15 C-12M combine harvesters. During the 83-year wheat harvest, three of the final drives broke teeth. For the final drive gear teeth of the failure, in addition to the reasons for the tooth we analyze, but also the other 12 were checked and found that large and small reduction gear have different degrees of abnormal damage. Ubiquitous tooth surface hardened layer off and offset printing phenomenon. To this end, we analyze the structure, use, adjustment and maintenance of the final drive of the model and propose measures for prevention.
