The common differential planetary gear is selected as the research object, and its parameters are shown in the table.
Number of teeth | Modulus | Pressure angle° | Sub cone angle° | Tooth width° | Top cone angle° | Root cone angle° |
11 | 6.5 | 22.5 | 31.43 | 20 | 36.1 | 26.18 |
The tooth surface of spur bevel gear is a complex curved surface, and the three-dimensional modeling is difficult. A special three-dimensional modeling software is selected to complete the design of spur bevel gear part drawing according to the parameters of the table, as shown in the figure.
