Abstract
Due to the current demand for reducing the power consumption particularly in the transportation sector intensive research is carried out to achieve resource efficiency. To fulfil future trends in sustainability machine elements offer possibilities to enhance the surface and part properties and to reduce the components weight and costs. This paper describes the potentials, which the combination of two current research projects in mechanical engineering can offer to improve rolling element bearings. A cylindrical roller bearing will be used as an example. By applying residual stresses to the bearing surfaces, it could be proven that the bearing fatigue life can be increased by a factor of 2.5. For this purpose, an adoption of the manufacturing processes is needed. With an enhanced near surface zone the machine dimensions can be reduced to fulfil the required function. In a second step, hybrid machine elements with tailored material properties are designed and manufactured. Concerning this, a shaft with an integrated raceway made out of a higher strength material than the shaft itself was developed. The raceway of the shaft acts like the inner ring of a bearing. This complex machine element combines various requirements in one part like resistance against structural stresses and a surface under cyclic rolling contact fatigue. For the hybrid shaft, the raceway should resist the rolling contact fatigue and mechanical wear, while the main material for the shaft consists of a more lightweight and cheaper material. In order to manufacture said shaft, intensive research on the overall product engineering process is done. Numerical simulations and experimental studies are used to prove the reliability of the described concept.
