Based on the analysis of the merits and demerits of helical gears and herringbone gears, a new toothed cylindrical gear is proposed, which is a symmetrical arc cylindrical gear.According to cutter parameters, Development method, successfully solved the mismatch control and processing of such a key issue of the gear.Analysis of the processing principle in a common multi-axis CNC machine tools, the establishment of a mathematical model.According to the analysis of spatial relative motion, proposed The method to determine the coefficient of each motion axis is discussed and the gear surface equation and differential geometry parameters are analyzed and discussed.The results show that this kind of gear has the characteristics of high bending strength, stable operation, no axial force and so on. , This new symmetrical arc-shaped spur gear is a promising high-performance heavy-duty drive gear.
