Heat generating machine has main rotor component setting viscous medium under shear and made from material with larger thermal expansion coefficient than that of drive shaft

摘要

The machine's rotor(9) rotating in a heat generating chamber includes a main rotor component(9a) setting the viscous medium under shear and which is made from a material with a larger thermal expansion coefficient than that of the drive shaft(8). The rotor has a bush made from a material with a thermal expansion coefficient which is the same as that of the drive shaft. The bush is fitted in the main rotor component and attached on the drive shaft, and is positioned so that it makes contact with the inner race(7a) of a bearing.
