ABSTRACT:
In the case of a crankshaft with hollow pins, cross-sectionally distributed expanding sleeves inserted into the exit apertures of the main pins and crank pins in the crank webs. These sleeves generate a prestress in the material of the crank webs in order to increase the bending and torsional strength and to avoid the formation of cracks in the endangered shaft cross-section. Further expanding means in the pins extending along the length of the pins increase the natural frequency of the shaft in uncritical areas.
