Abstract Scope |
The application of high strength sintered gears in the power transmission requires optimized surface densification and heat treatment processes to improve the load bearing capacity and service life of the part. A macroscopic modelling approach is developed to integrate the heat treatment simulation and the prediction of the load bearing capacity of case-hardened, sintered gears. The model describes quantitatively the microstructure changes and the evolution of internal stresses, depending on the process parameters. The analysis of the load bearing capacity is based on the calculated local degree of utilization, considering the full stress tensor as a result of the gear testing loads and residual stresses. The fatigue strength of the sintered steel is adopted from an available data set, depending on the density, carbon content and the highly loaded volume of the part. The model represents a digital tool to investigate the correlation between process parameters, material state and properties. |
