In order to establish the straight bevel gear sketches and simulation model database

the straight bevel gear profile involute mathematical model is established

and a bevel gear tooth involute profile of the spherical projection formed into the circle involute by using the central projection.According to the principle of mechanical design

a straight bevel gear simulation model database is built based on CAD software.The results show that the design and processing straight bevel gear is convenience in a large degree by building the simulation model and database

the cost of design and processing for straight bevel gear can be reduced greatly

and it is helpful for teaching and training of gear.
