に維持する装置。 An oil receiving member made of a material with a high coefficient of thermal expansion and having an oil chamber is interposed between the outer ring of the main shaft bearing of a machine tool, a passage communicating with the oil chamber provided in the main shaft housing, and the temperature of the oil receiving member are controlled. The optimum oil receiving member length is determined by comparing the temperature sensor to be detected, the oil receiving member length calculated from the temperature detected by the temperature sensor, and the oil receiving member length that can provide the optimum preload amount calculated from the spindle rotation speed. A device for maintaining a constant preload on a main shaft bearing of a machine tool using temperature-controlled oil, characterized by comprising an oil supply device that supplies oil at the obtained temperature to an oil chamber through a passage.
