Abstract
The deformation of gear blank is serious in the machining process of the split straight bevel gear, considering the material and the design of gear blank, the relationship between the change of additional stress and bending deformation of gear blank is studied, and the calculation model of the internal additional stress and additional torque during the gear cutting is established. According to the moment-area method, the calculation formula of the bending deformation of gear blank is derived, and combined with the time-varying stiffness, the mathematical model of the gear blank deformation is obtained. The theoretical calculation, finite element analysis, and experimental results are highly consistent. Based on the above research, the internal relationships between the machining deformation and the geometric parameters such as the thickness, diameter, and gear module of the split gear blank are analyzed, and the reasonable design of the geometric parameters of the split gear blank and the reasonable dividing law of the gear blank are explored.
