产品特点：

Gear Bearing PT400转子齿轮轴承测试台采用ABB小型三相异步电机由皮带轮驱动，配合变频器来调节 转速，皮带驱动转子部件，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、皮带驱动测 试、转子动平衡试验、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，配合教学模拟及科研用户的广泛需求。PT400 adopts ABB small three-phase asynchronous motor driven by belt pulley,  combined with frequency converter to adjust the speed. The belt drives the rotor  components, and different types of bearings can be selected to verify the  frequency characteristics of bearing defects at different speeds. It can also  perform fault gear testing, belt drive testing, rotor dynamic balance testing, start  stop testing, and shaft friction testing. It can be tested 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.
