Problems solved by technology

[0002] A gear is a mechanical element that has teeth on the rim and can continuously mesh to transmit motion and power. It is a toothed mechanical part that can mesh with each other. The application of gears in transmission has appeared very early. When working, the force received is relatively large. At the same time, when the power is transmitted, the vibration of itself and the mutual meshing process between the gears will receive a certain force. If things go on like this, the gears will suffer certain fatigue damage, which will greatly reduce the transmission. performance, therefore, how to improve the fatigue resistance of gears is a technical problem that needs to be solved
