The bearings 2 and 3 located between the main shaft 1 and the bearing stand 4 have the purpose of helping the main shaft 1 to rotate smoothly.
Heat is generated due to rolling friction. As described above, the temperature of the conventional bearing pedestal 4 increases due to the amount of heat generated when the bearings 2 and 3 rotate, and various parts of the bearing pedestal 4 undergo various deformations and strains due to thermal expansion. For this reason, the position of the spindle 1 in the vertical, horizontal, and longitudinal directions fluctuates with rotation or time, resulting in disadvantages such as poor processing accuracy. This invention was made in order to eliminate the drawbacks of the conventional ones as mentioned above.

ァン１６を介して周囲空気により冷却される。Next, the operation will be explained. The amount of heat generated by the bearings 2 and 3 is taken away as latent heat of vaporization when the working liquid filled in the grooves 8 and 11 is heated and vaporized, and the vaporized vapor is transferred to the steam pipe 12 using its own vapor pressure. , coupling 1
3. It moves to the heat radiating section 15 via the steam pipe 14 and is cooled by the surrounding air via the cooling fan 16.
このときに、蒸気は凝縮して液体にもどるが、その際に
凝縮潜熱を周囲空気中に放出する。At this time, the vapor condenses back to liquid form, releasing latent heat of condensation into the surrounding air.
