Rolling friction abrasion testing machine

The invention relates to a rolling friction abrasion testing machine, which comprises a machine frame, a driving module, a transmission module, a loading module, a torsion detection system, a constant temperature water bath (6) and a constant temperature water bath base plate (7), wherein the machine frame consists of a machine frame back plate (11) and a machine frame bottom plate (12); the torsion detection system comprises a torsion sensor (51) and a signal acquisition processing meter (52); the signal acquisition processing meter (52) is fixed on the machine frame back plate (11) and is connected with the torsion sensor (51); the constant temperature water bath base plate (7) is arranged on the machine frame bottom plate (12); and the constant temperature water bath (6) is movably arranged on the constant temperature water bath base plate, and can accommodate a dual friction disc (35) and a test sample to be detected (47). The rolling friction abrasion testing machine can simulatedifferent temperatures and liquid environments to perform rolling friction abrasion tests of polymers and dual pieces.
