This paper illustrates the processing art method of the hard gear wheel with big modulus in accordance with the mill wheel machine equipment in our factory and analyzed the big modulus gear wheel.

The feederless foundry method for a large ductile iron gear wheel was described.

It is shown that the macrocracks are initiated by a strong stress in the root of the gear wheel,and the distribution as well as the propa-gation of the fatigue crack are the characterstics of the resonance.

The resulting assurance coefficients are different if choose different reliability levels as requests during wheel gear strengths calculation.

The loss of power by using the wheel gears mainly lies in the loss of the surface of action,the loss of oil resistant when the gears stir the lubricating oil,and the loss of bearings.
