の予圧調整機構。 When the main shaft is supported by multiple bearings, the distance collars, which are interposed to provide preload between the bearings and/or between the bearings and the bearing clamping part, are related to changes in preload on the inner and outer rings, and the rotation of the main shaft. The inner ring and outer ring are made of materials with different coefficients of thermal expansion to compensate for changes in bearing preload due to thermal displacement of various parts due to heat generation in the bearing. Features a preload adjustment mechanism for machine tool main bearings.
