PT500 Drivetrain Diagnostics Simulator

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.

The test bench is mainly composed of three-phase asynchronous motors, frequency converters, double support bearings, dynamic balancing rotor discs, oil circulation systems, shafts, two-stage transmission gear sets, planetary gearboxes, magnetic powder load torque adjustment mechanisms, shock-absorbing foundation bases, adjustable magnetic powder load brake components, etc.
