Description
【特許請求の範囲】
【請求項１】 主軸と、ハウジングと、前記主軸と前記ハウジング間に介在し、前記主軸を回転可能に支持する少なくとも1つの転がり軸受とを備える転がり軸受装置において、前記転がり軸受の一部分と前記ハウジングとを実質的に一体の固定部とし、前記転がり軸受の外周面と前記ハウジングの内周面とが互いに軸方向に亘って対向する対向部の一部分を所定の隙間量を有する隙間部とし、前記固定部と前記隙間部との間に所定のばね定数を有するばね作用部を設けるとともに、前記隙間部に油を充填したことを特徴とする転がり軸受装置。
【請求項２】 前記転がり軸受装置の転動体部分のばね定数と、前記ばね作用部のばね定数とを近似的に同等したことを特徴とする請求項１に記載の転がり軸受装置。
[Claims]
1. In a rolling bearing device including a spindle, a housing, and at least one rolling bearing that is interposed between the spindle and the housing and rotatably supports the spindle, a part of the rolling bearing and the housing. Is a substantially integral fixing portion, and a part of the facing portion where the outer peripheral surface of the rolling bearing and the inner peripheral surface of the housing face each other in the axial direction is a gap portion having a predetermined gap amount. A rolling bearing device characterized in that a spring acting portion having a predetermined spring constant is provided between the fixed portion and the gap portion, and the gap portion is filled with oil.
2. The rolling bearing device according to claim 1, wherein the spring constant of the rolling element portion of the rolling bearing device and the spring constant of the spring acting portion are approximately equivalent to each other.
