產品特點：

PT500多級齒輪箱故障模擬測試臺采用ABB1.5千瓦三相異步電機由聯軸器直接驅動，配合變頻器來調節轉速，可調磁粉負載給測試臺增加測試負載。可以選擇不同故障類型的軸承，在不同轉速下，驗證軸承缺陷頻率特征，還可進行故障齒輪測試、油液循環系統、轉子動平衡試驗模塊、啟停機試驗、轉軸摩擦試驗，在安全可控的環境中單獨或與各種缺陷組合搭配實驗。作為研究旋轉機械故障特征的創新實驗平臺，滿足教學模擬及科研用戶的廣泛需求。  

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.
