RSIME Railcar Bearing Tester

RSIME designed a built a bearing tester so to evaluate rail vehicle bearings.  It was designed to simulate the static load of a loaded or empty railcar on the bearings.  This was accomplished with hydraulic rams.  A 50-horsepower motor turns a axle with four testing bearing mounted on it.  A vector inverter motor controller allows testing to be done at any speed, up to 100+ mph.  A torque sensor measures and records the bearing torque of the coarse of a test.  Bearing temperatures are also measured using a data acquisition system.  Two large fans simulate the cooling effect of air rushing past the bearings like when a railcar is traveling down the track.
