First, the differences between tooth surface friction and general contact surface friction are analyzed, and the technical difficulties and requirements of testing of tooth surface friction are discussed based on the testing methods of general contact surface friction Then, current testing methods of tooth surface friction, including resistance strain gauge meth-od, equivalent torque method, equivalent gravity pendulum method, and photoelasticity method, are introduced. The principles, advantages and disadvantages, and scope of application of these methods are described in detail. Next, the above four testing methods are compared from the viewpoints of testing accuracy, range, and complexity. In addition, the remained problems of each method are pointed out. Finally, several topics to be further studied are presented.
