某斜齿轮轮轴的有限元分析

文中所分析的某设备齿轮轴是整个设备的重要零件,由于该轴的齿形为斜齿,而且局部还有键槽、轴肩等特殊形状,因此其应力集中现象较严重.为了准确地掌握整个轴特别是一些特殊部位之应力情况,运用有限元理论,采用有限元分析软件ANSYS对该齿轮轴进行有限元分析,掌握了其应力、应变分布规律,并确定出出其危险部位,从而为该轴的安全工作提供可靠的理论依据.通过分析发现,齿根处和轴肩过渡处应力值很高,这与实际应用过程中经常发生断裂的情况是一致的.

Finite element analysis on the gear-shaft of helical gear teeth

The Gear-Shaft analyzed is the most important parts of some equipment. Because it is the helical teeth shape, and partials is special form,So that the stress concentration is very serious Based on the finite element theory. The shaft was analyzed by FEA software(ANSYS) to analyze the stress and distortion, to grasp it's stress and distortion distribution and to find out the danger place. By analyzing, the stress of teeth-root is higher,it is coherent with the actual crack condition.
