Modern gear calculation programs give us the possibilityto determine the load carrying capacityand the noise behavior of a gear transmission considering the shaft and bearing system, the tooth modifications and the production deviations. While load and stress optimized tooth modifications are quite insensible to the normal production deviations; noise and vibration optimized tooth modifications need a much higher production accuracy because of the low values of the transmission errors caused by the changes of the mesh stiffness.
The numerical simulation leads often to more complex modifications which can not be realized with normal standard modifications like crowning and root or tip relief. Topological modifications are required and have to be realized in the grinding process. Differences between the common profile grinding method and the generating grinding method based on the different contact situations between grinding wheel and gear gap will be shown.
