Taking the pinion in the spiral bevel gear transmission pair with transmission ratio of 0.5 as an example, the simulation analysis of gear cutting is carried out. Before the simulation of gear cutting, the bevel gear blank model must be established, and the geometric parameters of the gear blank need to be designed to establish the gear blank model.

Select the proper gear set from the rating data chart for the ratio required. (An "L" or "R" in the part numbers indicate left or right hand spiral.) 5 

Taking the spiral bevel gear with 15 teeth and 9 modulus as an example, the parameter design of gear blank and the establishment of simulation machining model are carried out. The parameters of bevel gear blank are divided into original parameters and calculation parameters, and the original parameters are shown in Table 1.
