针对长期在复杂工况下运行的高速电梯曳引机主轴综合性能是否失效无法准确判断的问题,设计一种高速电梯主轴组件可靠性检测装置。根据高速电梯主轴双支撑简支结构的特点,确定了装置的原理、结构和测试流程。通过在试验装置上由电机驱动高速电梯曳引机使主轴高速旋转,获取在旋转过程中所产生的振动信号以及轴承的温度信号,再经过相应传感器进行数据采集;结合温度值的设计上限阈值、振动值的波峰因子临界阈值和峭度临界阈值,分析判断高速电梯曳引机主轴或轴承是否失效。试验表明:高速电梯主轴组件综合性能检测方法和失效判据准确,达到一定的量化应用要求。

To solve the long standing problem of failing to accurately judge the comprehensive performance of high-speed elevator spindle running under complicated working conditions,a reliability device for high speed elevator spindle components was developed.According to the characteristics of high-speed elevator shaft double support simply-supported structure,the principle,structure and test process of the device were determined.With the test device,the motor driven by high speed elevator traction machine was applied to run spindle at high speed to obtain the vibration signal and bearing temperature signal generated in the sipndle spinning process,and relevant data was acquired by appropriate sensors.Combined with the upper limit threshold of temperature value,the peak factor critical threshold of vibration value and the kurtosis critical threshold value,the failure of the spindle or bearing of the high-speed elevator traction machine was analyzed and judged.The test results show that the comprehensive performance test method and failure criterion of high-speed elevator spindle assembly are accurate and can meet certain quantitative application requirements.
