摘要

To improve the dynamic performance of spiral bevel gear transmission, an ease-off flank modification method of the high-contact-ratio spiral bevel gear is proposed. First, the high-contact-ratio spiral bevel gear is designed by increasing the angle between the contact path and the pitch cone of a pinion tooth surface with ease-off technology. Second, the meshing performance of the high-contact-ratio spiral bevel gear designed utilizing ease-off technology is compared with the HCR spiral bevel gear designed by the local synthesis method. Finally, the loaded transmission error (the main vibration excitation of the gear transmission in the low-speed range), the meshing impact (the main vibration excitation of the gear transmission in the high-speed range) and the dynamic performance of the high-contact-ratio spiral bevel gear are compared with that of a low-contact-ratio spiral bevel gear. A simulation analysis based on the ease-off technology shows that the design contact ratio of the spiral bevel gear can be improved by increasing the angle between the contact path and the pitch cone of the pinion tooth surface; compared with the local synthesis method, the high-contact-ratio spiral bevel gear transmission designed by the ease-off flank modification method has a better meshing performance; increasing the design contact ratio can effectively reduce the loaded transmission error, and meshing impact, and obtain a spiral bevel gear transmission with good dynamic performance over the whole speed range.
