产品特点：

PT500多级齿轮箱故障模拟测试台采用ABB1.5千瓦三相异步电机由联轴器直接驱动，配合变频器来调节转速，可调磁粉负载给测试台增加测试负载。可以选择不同故障类型的轴承，在不同转速下，验证轴承缺陷频率特征，还可进行故障齿轮测试、油液循环系统、转子动平衡试验模块、启停机试验、转轴摩擦试验，在安全可控的环境中单独或与各种缺陷组合搭配实验。作为研究旋转机械故障特征的创新实验平台，满足教学模拟及科研用户的广泛需求。  

The P500 Multi-stage Gearbox Fault Simulator adopts ABB 1.5 kW three-phase asynchronous motor driven directly by  coupling, with frequency converter to adjust the speed, and adjustable magnetic powder load to increase the test  load on the test bench. Bearings with different types of faults can be selected to verify the frequency characteristics  of bearing defects at different speeds. Fault gear testing, oil circulation system testing, rotor dynamic balance testing  module, start stop testing, and shaft friction testing can also be conducted separately or in combination with various  defects in a safe and controllable environment. As an innovative experimental platform for studying the fault characteristics of rotating machinery, it fully meets the extensive needs of teaching simulation and scientific research users
