| 摘 要： | 为了研究现有工艺下拖拉机动力输出被动齿轮的疲劳寿命,选取共振式高频疲劳试验机,对随机选取的某一型号拖拉机动力输出齿轮进行弯曲疲劳试验,测得齿轮的疲劳极限载荷和S-N曲线。通过试验取得的数据,为拖拉机齿轮的可靠性设计和寿命评估模型的构建提供依据。

| Abstract: | In order to investigate the fatigue life of tractor PTO’s passive gear under the actual technics,the fatigue experiments were performed by syntonic high-frequency test-bed.The tractor PTO’s passive gear was selected at random,and the bending fatigue tests were done.The gear’s fatigue life limit and S-N curve were gained.The experimental data can be acted as the data for the tractor gear’s reliable design and the construction of the model for evaluating life. |
