The method of determining the tooth profile of the deflection mesh type gear device and deflection mesh type gear device

摘要

PROBLEM TO BE SOLVED: To improve impact resistance to further increase transmission torque and transmission efficiency.;SOLUTION: This flexible meshing type gear device 100 includes cylindrical external tooth gears 120A, 120B with flexibility, and an internal tooth gear 130A for reduction and an internal tooth gear 130B for output having rigidity and allowing the external tooth gears 120A, 120B to be internally meshed therewith. Tooth profiles of the external tooth gears 120A, 120B at portions meshed with the internal tooth gear 130A for reduction and the internal tooth gear 130B for output are the same. The external tooth gears 120A, 120B, and the internal tooth gear 130A for reduction and the internal tooth gear 130B for output have tooth profiles, respectively, so that the number Nph of simultaneous mesh between the external tooth gear 120A and the internal tooth gear 130A for reduction and the number Npl of simultaneous mesh between the external tooth gear 120B and the internal tooth gear 130B for output are both 2 or larger.;COPYRIGHT: (C)2011,JPO&INPIT
