一. main application
GPM-40 rolling contact fatigue test bench is mainly used for the failure test to simulate the working condition of rolling contact parts, and a constant load is applied to the rolling or rolling and sliding contact sample, so that the contact surface is subjected to the cyclic contact stress. To evaluate the comprehensive performance of sample materials by controlling and changing the load, speed, slip rate, time, friction mate material, surface roughness, hardness, etc.
The machine for horizontal frame structure, controlled by imported ac servo motor loading and rotation, the test parameters to set, easy to operate, accurate and reliable test reading, through the computer to control the parameters, can real-time display friction moment-time, test force-friction coefficient curve, and record, save, and print the test curve.
