提高传动轴疲劳强度的实证与分析

Demonstration and Analysis to Increase Fatigue Strength of Transmission Shaft

轴类零件在设备中普遍使用且非常关键,生产现场轴类断裂的故障时有发生.通过下料小车轴断裂改进的实证,从使用状况、零件结构、力学分析等方面对下料小车轴固定使用状况、固定位置断裂的原因进行追索,归纳了轴类零件疲劳强度的影响因素,以提高设备使用与维护的预见性、针对性。

The shaft is the key part and widely used in the equipment, but the accident of shaft broken occurs from time to time at the production site. Through the trials of reducing the shaft＇s fatigue breaks of a discharging cart, seeking the reason breaking on the fixed condition （driving shaft） and the fixed locality from its operating condition, structure and mechanics analysis, the author sums up the influential factors on the shaft＇s fatigue strength so as to improve equipment management including accident prediction, equipment maintaining pertinence and efficiency.
