温度が上昇することになる。According to the above precepts, if only the far-infrared emitting ceramic is heated, far-infrared rays will be emitted from this ceramic,
As a result, the lubricating oil at the PJ friction rolling site between the planetary roller, fixed wheel, and sun roller is efficiently heated. In general, polymer compounds such as grease and lubricating oil absorb far infrared rays well, and the energy of far infrared rays is converted into vibrational energy of molecules, resulting in an increase in the temperature of grease, lubricating oil, etc.
