Abstract:
A new type of gearing, symmetric arcuate tooth trace cylindrical gears, is introduced, based on analyzing the advantages and disadvantages of helical and herringbone gears. The key problems of mismatch control and manufacture of symmetric arcuate tooth trace gears are perfectly solved by using suitable cutter tilt and new generating method. The machining principle is analyzed and a mathematical model is established. The tooth flank equation and differential geometrical parameters are also discussed. The results show that the new type of gearing possesses the characteristics of convenient mismatch control, smooth running, no axial force and so on. It can be predicted that symmetric arcuate tooth trace gears will be a hopeful highly durable and heavy duty gearing.
