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。
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 evalu;,ting life.
