1. A method for production of a sintered gear wheel comprising the following sequential steps:

  • designing the sintered gear wheel using predetermined geometry and loading data,simulating a load computation and a noise prediction for the sintered gear wheel as designed,selecting at least one noise reducing structure for the sintered gear wheel in which the at least one noise reducing structure is in addition to porosity of the sintered gear wheel and further integrating the at least one noise reducing structure into the sintered gear wheel as designed,verifying a load computation and a noise prediction for the sintered gear wheel as designed including the at least one noise reducing structure,once or more, optionally adapting of the sintered gear wheel as designed including the at least one noise reducing structure and repeating of at least the verifying of the noise prediction or the load computation,drafting of manufacturing data based on the sintered gear wheel as designed including the at least one noise reducing structure and as optionally adapted and verified and manufacturing of the sintered gear wheel on the basis of the manufacturing data.
