[0002] Gear is a commonly used mechanical part in speed reducer, and also belongs to high-speed precision gear transmission device. In the prior art, when the staggered shaft transmission is used, the quasi-hyperboloid gear and the cylindrical helical gear are often used. When the speed reduction ratio is greater than 10 or the speed reduction ratio is 30, the number of teeth of the pinion needs to be less than 4 teeth. At this time, if the quasi-hyperboloid gear with high speed reduction ratio is used, the following problems exist: the small end diameter is too small and the tooth is easy to break; the processing and use are high in sensibility and high in assembly difficulty.
