【Abstract】 Design method for DIGLST (double involute gear with ladder shape teeth) having the equal bending be is adduced, and the maching relationship between ladder fartors y and l* is optimized by FEM, and the choice table and empirical formul for laddr factors design are also Provided. Arithmetic optimizing model is construted for gear trasmission with equal strength. The arithmetic for bbending be of DIGLST is Presented after the coefficients of helix angle and contact lines are analyzed by 3-D FEM.更多还原
