针对重载挖掘机减速器齿轮负载极大和偏载的工况,作了全齿面接触分析。为获得精确的齿面应力分布,建立了准确的实体模型,分析了整个齿面在啮合过程中的应力情况,并按照AGMA标准以齿廓上5个特殊点为应力考察的主要对象进行了结果后处理的对比分析。 Aiming at the condition that the gear of heavy-duty excavator reducer is under heavy load and partial load, the full-tooth surface contact analysis is made. In order to obtain accurate tooth surface stress distribution, an accurate solid model was established, the stress condition of the entire tooth surface during the meshing process was analyzed, and the results were obtained according to the AGMA standard with five special points on the tooth profile as the main object of stress investigation Comparison of post-processing analysis.
