传统渐开线齿轮理论认为 :齿轮机构在运行过程中齿面会发生磨损 ,然而 ,轮齿齿廓将仍然维持渐开线的形状。作者系统地研究了影响高速及中低速齿轮齿面磨损的诸因素 ,并通过分析及计算对高速及中低速齿轮磨损后轮齿齿廓进行定性的描述。研究表明 :高速齿轮机构长期运行后 ,由于被磨损轮齿的齿廓不再保持渐开线形状 ,因而会加剧齿轮机构的振动 Traditional involute gear theory that: the gear mechanism in the operation of the tooth surface will wear, however, the gear tooth profile will still maintain the involute shape. The author systematically studied the factors that affect the gear wear of high-speed and medium-low speed gears, and analyzed and calculated the tooth profile of the high-speed and medium-low speed gear wear qualitatively. The research shows that after the high-speed gear mechanism is operated for a long time, the tooth profile of worn gears will no longer maintain involute shape, which will aggravate the vibration of the gear mechanism
