Abstract

　回転体に電極を接触させることなく軸受にかかる予圧を求めることができ、製造コストの低減を図ると共に、装置部品の長寿命化を図ることができる軸受装置を提供する。軸方向に並ぶ複数の転がり軸受３Ａ，３Ｂの軌道輪３ｉ，３ｉ（３ｇ，３ｇ）間に間座４（５）が介在し転がり軸受３Ａ，３Ｂが予圧を受ける軸受装置であって、いずれか一の転がり軸受３Ａにおける固定輪３ｇに電気的に接続された電極１１、および固定輪３ｇに対して固定状態の部材に設けられ回転輪３ｉに対し一の転がり軸受３Ａとは別の静電容量発生部３Ｂを介して電気的に接続された電極１２を設け、これら一対の電極１１，１２間の静電容量Ｃを測定する静電容量測定手段９を設け、この静電容量測定手段９の測定値から転がり軸受３Ａ，３Ｂの予圧を検出する予圧検出手段１０を設けた。
