摘要

结合可靠性理论和模糊理论,以某圆柱斜齿轮副接触疲劳可靠性为研究对象对齿轮可靠度计算方法进行了一定改进,以Matlab为工具进行数值模拟,得到了工作一段时间后圆柱斜齿轮接触疲劳可靠度的大小并与常用可靠性计算方法得到的结果进行了比较。结果表明,改进后的方法考虑因素更为全面,为齿轮可靠度计算提供了一定参考。

Abstract

Reliability and fuzzy theory was applied to analyze the contact fatigue reliability of cylindrical helical gear. Furthermore, the calculation method has been improved. The reliability for contact fatigue of cylindrical helical gear after working a period of time was obtained used Matlab as a tool for numerical simulation and it has been compared with the results based on general approaches. The result shows that the improved method is more comprehensive consideration than general methods. Moreover, it provides a reference for reliability calculation of the gear.
