The invention discloses an end face torsion frictional
wear testing machine and an end face torsion frictional
wear testing method. The testing
machine comprises a transmission device and a pressure loading device, wherein the transmission device comprises a
servo motor, a speed
reducer, an eccentric wheel and a connecting rod; and the pressure loading device comprises a
force sensor, a thrust
ball bearing, a fixing piece, a spindle, a turntable, a turntable connecting rod, a tray, a
torque sensor, a lifting shaft, a sliding sleeve and a
hydraulic cylinder. A test piece is axially pressurized through the
hydraulic cylinder, a connecting rod transmission mechanism drives the test piece to perform frictional torsion, a frictional torque value is measured through the
torque sensor, and a
positive pressure value is measured through the
force sensor so as to obtain a
friction coefficient. An end-face contact torsion frictional wear test under different working conditions can be simulated by setting different positive pressures, torsion frequencies and the like, and the frictional torque is accurately measured; and the loading is stable and accurate, the
impact is low, and
dynamic loading can be realized. Moreover, the
machine is simple in structure, convenient to operate and good in testing effect.
