Spiral bevel gear has the advantages of large overlap coefficient, strong bearing capacity, stable transmission and low noise. It is widely used in gear transmission with high circumferential speed, large bearing capacity, stable transmission and low noise. It is an indispensable key transmission part in vehicles, ships, tanks, aircraft, oil drilling machines and other equipment.
Compared with the tapered teeth, the bending strength of the small wheel can be increased by more than 10%, the bending strength of the large wheel can be increased by more than 14%, and the contact fatigue life can be increased by 30%, which greatly improves the service time of the gear. Therefore, the comprehensive performance of the contour teeth is better than the tapered teeth. With the more and more extensive application of equal height teeth, engineers use UG / OpenGRIP more and more. Therefore, it is of great significance to use UG / OpenGRIP for three-dimensional automatic modeling of equal height spiral bevel gear and its precision forging die. On the other hand, the research on precision forging technology of equal height teeth is also of great significance to its actual machining.
Using UG / OpenGRIP secondary development language to carry out three-dimensional automatic modeling of equal high tooth spiral bevel gear and its precision forging die can simplify geometric parameter calculation, improve modeling accuracy, reduce cost, improve work efficiency, reduce labor intensity and standardize parts. Studying the forging process of equal high tooth spiral bevel gear has significant advantages in reducing material waste, improving production efficiency, strengthening the mechanical properties of gear and reducing cost, especially in the automotive industry.
