Description
technical field [0001] The present invention relates to the technical field of harmonic gear transmission testing, in particular to a harmonic gear tooth surface friction test system based on photoelastic coating method and the harmonic gear tooth surface friction test system based on photoelastic coating method Test methods for force test systems. Background technique [0002] Harmonic gears have the characteristics of multi-teeth meshing. The friction in the meshing area during the transmission process will not only cause energy loss, but also cause stiffness hysteresis, which will cause great harm to the transmission performance. [0003] To this end, it is necessary to obtain the real change law of the harmonic gear tooth surface friction, and realize the accurate modeling and compensation of the harmonic gear tooth surface friction. [0004] The test method of harmonic gear tooth surface friction in the related art has the complex manufacturing and pasting process of t...
