摘要
针对现行的齿轮可靠性设计中多将影响齿轮的随机因素及齿轮应力和强度分布简单假定为正态或对数正态分布,与实际分布差异较大的情况。论文探讨一用威布尔分布描述影响齿轮的随机因素,应用极限状态理论进行齿轮传动可靠性设计方法;由于威布尔分布的灵活性,使其描述的分布状态与实际情况更接近从而设计更可信。文中对渐开线圆柱齿轮进行了可靠性设计,并开发了计算机应用程序,可以迅速准确地给圆柱齿轮的可靠性设计信息。
In the current gear reliability design, the distribution of random factors is simply supposed to normal distribution or logarithmic normal distribution that has difference from actual distribution. To counter this design state, we explore a gear transmission reliability design method in which weibull distribution is used to describe the random factors and ultimate status theory is applied to calculate the reliability. Owing to the flexibility of weibull distribution, the distribution state described by weibull distribution is close to actual distribution and the calculating accuracy is raised. The cylindrical gear reliability is designed and calculated using this method. The computer program can be designed to obtain the reliability design information of cylindrical gears accurately and quickly.
