転がり軸受が軸箱内に装着され、前記転がり軸受に支承される軸と前記軸箱との間を密閉するシール部材が前記軸箱に設けられた転がり軸受装置において、
前記転がり軸受の内輪、外輪及び転動体により形成される空間内に潤滑剤含有ポリマーが充填され、前記シール部材の前記軸に接する先端部が前記空間から離れる外向きにされ、前記軸箱に設けられた供給路を介して前記空間に圧力３０ｋＰａ以上の圧縮気体が供給された際に、前記シール部材と前記軸との間から気体が排出されることを特徴とする転がり軸受装置。In the rolling bearing device in which a rolling bearing is mounted in the shaft box, and a seal member that seals between the shaft box supported by the rolling bearing and the shaft box is provided in the shaft box.
The space formed by the inner ring, the outer ring and the rolling element of the rolling bearing is filled with a lubricant-containing polymer, and the tip of the seal member that contacts the shaft is directed outwardly away from the space, and is provided in the shaft box. When a compressed gas having a pressure of 30 kPa or higher is supplied to the space through the supplied supply path, the gas is discharged from between the seal member and the shaft. 前記空間には圧力３０ｋＰａ以上３００ｋＰａ以下の圧縮気体が供給されることを特徴とする請求項１記載の転がり軸受装置。The rolling bearing device according to claim 1, wherein a compressed gas having a pressure of 30 kPa to 300 kPa is supplied to the space. グリース潤滑が併用されることを特徴とする請求項１または２記載の転がり軸受装置。3. The rolling bearing device according to claim 1, wherein grease lubrication is used in combination.
