橡胶带接头疲劳强度测试实验台的研究

On fatigue strength test rig for rubber belt joint

阐述了输送机橡胶带的接头疲劳强度测试方法,介绍了实验台的实验机理和控制方式,将输送带的安全性能设为最高等级,以此为参考确定了接头疲劳性能和寿命测试实验条件,计算了输送带的张力及破断力,根据系统张力、功率以及辊子运行速度,对电机和减速器进行选型。

The paper describes fatigue strength measuring method of belt conveyor＇s rubber belt joint, and test mechanism and control method of test rig. It also covers how the joint＇s fatigue property and fatigue life test conditions are determined under the desired top level safety, how the conveying belt＇s tension and breaking force are calculated, The motor and gear box can be selected according to the system tension, power, and roller speed.
