Research on Active Design and Machining Method for Spiral Bevel Gear
Aiming at the design and manufacture of face milling spiral bevel gear,the mathematical model of machining method based on free-form surface machine tool is established.The active design and manufacture of spiral bevel gear milling are com-pleted by fixing the workpiece shaft on the free-form surface machine tool.Taking the meshing performance parameters as the in-put variables,the mathematical model of gear meshing is established,and the gear tooth surface is actively designed according to the designed contact attributes.In addition to the first-order and second-order parameters of the average contact point on the side of each pinion controlled by the traditional method,this method can also ensure each contact path point on the common driv-ing side of the pinion at the same time,avoiding the error and manufacturing difficulty caused by the poor motion accuracy of the workpiece shaft.Finally,the method is verified by tooth contact analysis(TCA)and rolling test.
