Based on the calculation of the gear tooth hardness of the driving axle in the ZL50 wheel loader, the suitable hardness of the gear tooth of the internal gear which meets the design and application requirements and is easy to be processed is determined. At the same time, this method is also applicable to the gearbox, drive spur other spur gear hardness calculation.
