本讲主要介绍齿轮可靠性试验的方法及试验数据的统计处理,并简单介绍统计试验法。 1、齿轮可靠性试验的目的和特点在对齿轮零件或传动系统的可靠度进行分析和预测时,首先需要知道齿轮疲劳强度及寿命的统计分布规律,而获得这些规律的主要途径,是进行可靠性试验。通过试验,可以得出齿轮的各项可靠性指标,揭露薄弱环节,提出改进措施,达到提高产品可靠性的目的,所以,进行可靠性试验,是对齿轮可靠性预测、评价 This talk mainly introduces the method of gear reliability test and the statistical processing of test data, and simply introduces the statistical test method. 1. Purpose and Characteristics of Gear Reliability Test When analyzing and predicting the reliability of gear parts or transmission system, we first need to know the statistical distribution law of fatigue strength and life span of gear, and the main way to get these rules is to carry out reliable Sexual test. Through the test, we can get the reliability index of gears, reveal the weak links, propose improvement measures and achieve the purpose of improving product reliability. Therefore, to carry out reliability test is to predict and evaluate gear reliability
