Contact Tooth Bearing and Tooth Gap for Shaft Angle Fluctuation on Gear Coupling

Research on equivalent capacitance model of couplings of EMU

“…To study the mechanism of coupling leakage current, it is necessary to model and analyze leakage current circuit of EMU, and the coupling is an important component of leakage current circuit At present, domestic and foreign scholars have conducted relevant research on coupling model. Hakozak [4] established a model that includes internal and external tooth pairs, calculated minimum clearance between tooth surfaces under different axial inclination angles, and found that the minimum clearance between tooth surfaces is 5μm when the axial inclination angle is 5°. Nawate [5] studied the meshing overlap, maximum load on the tooth surface, and load distribution model, proposed a method for analyzing meshing overlap and tooth surface load calculation, and derived relevant formulas.…”
