摘要

为了研究齿根裂纹对硬齿面齿轮疲劳寿命的影响，以某渐开线硬齿面齿轮为研究对象，基于断裂力学方法和疲劳裂纹扩展理论，分析研究了齿轮齿根疲劳裂纹扩展机制；建立了考虑载荷大小、初始裂纹大小以及初始裂纹位置等因素影响的硬齿面齿轮齿根裂纹扩展剩余寿命分析模型，研究了齿根裂纹不同扩展阶段的应力强度因子演变规律与裂纹扩展机制；根据某渐开线硬齿面齿轮副弯曲疲劳试验数据，对所建计算模型进行了分析与验证，证明了模型的准确性。结果表明，与Ⅱ型裂纹、Ⅲ型裂纹相比，Ⅰ型裂纹应力强度因子最大，从齿面到裂纹深度方向，其值逐渐减小；随载荷、裂纹长度、裂纹宽度以及初始裂纹距齿宽中心位置的距离等因素的增大，裂纹扩展剩余寿命都随之减小。

Abstract

In order to study the influence of tooth root cracks on the fatigue life of case-hardened gears

taking an involute case-hardened gear as the research object

the mechanism of the tooth root fatigue crack growth is analyzed based on the fracture mechanics method and fatigue crack growth theory. The residual life analysis model of the tooth root crack propagation for case-hardened gears is established

considering the influence of load

initial crack size and initial crack location

etc. The evolution of stress intensity factor and crack propagation mechanism at different root crack propagation stages is studied. According to the bending fatigue test data of an involute case-hardened gear pair

the calculation model is analyzed and verified

and the accuracy of the model is proved. The results indicate that

compared with type Ⅱ and type Ⅲ

type Ⅰ stress intensity factor is the highest

which gradually decreases from the tooth surface to the direction of crack depth. With the increase of factors such as load

crack length

crack width

and initial crack distance from the center position of the tooth width

the residual life of crack propagation decreases accordingly.
