喷丸齿轮弯曲疲劳寿命数据库

弯曲疲劳主要面向齿轮弯曲疲劳寿命研究，为了提高齿轮弯曲疲劳寿命，实现齿轮抗疲劳设计制造，本数据根据《GB/T 14230-1993 齿轮弯曲疲劳强度试验方法》、《GB/T 3480-1997 渐开线圆柱直齿轮和斜齿轮承载能力计算》、《GB/T 17107-1997 锻件用结构钢牌号和力学性能》、标准，采用RUMUL 350kN高频弯曲疲劳试验机以单齿加载的形式对喷丸齿轮的9个轮齿开展升降法弯曲疲劳试验。根据施加载荷大小、齿轮以及轮齿对进行试验编号，同时记录试验过程中的施加载荷、频率、弯曲疲劳寿命以及弯曲疲劳失效形式等数据。This dataset is dedicated to gear bending fatigue life research, with the goal of extending gear bending fatigue life and achieving fatigue-resistant design and manufacturing of gears. Based on the Chinese national standards GB/T 14230-1993 Test Method for Gear Bending Fatigue Strength, GB/T 3480-1997 Calculation of Load Capacity of Involute Cylindrical Spur and Helical Gears, and GB/T 17107-1997 Structural Steel Grades and Mechanical Properties for Forgings, a RUMUL 350kN high-frequency bending fatigue testing machine was employed to perform ascending-descending bending fatigue tests on 9 teeth of shot-peened gears through single-tooth loading. Tests were numbered based on the magnitude of applied load, the tested gears and their tooth pairs, and key data including applied load, test frequency, bending fatigue life and bending fatigue failure modes were recorded during the experimental process.
