摘要： In rolling bearings the phenomena "breathing", i.e. increase and decrease of damp volume inside the bearing mainly due to temperature circumstances, is wellknown. In view of this phenomena the lip-seal (9') of the (mechanical) seal (9) will slightly but regular be pushed from its support i.e. the bearing innerring (2), which leads to escape of lubricant. To effectively avoid this leakage a second seal (5) having magnetic properties is added to the (mechanical) seal (9). This magnetic seal (5) is provided with grooves (6) and projections (7) adjacent the sealing side of the seal arrangement (5, 9). Mainly between said projections (7) magnetic fluid (8) is applied and fixed thereto due to the magnetic properties of the seal arrangement. Breathing inside the bearing (1, 2, 3) will now be resiliently received by said magnetic seal arrangement (5), without influencing the function of the seal- lip (9), thus preventing leakage of the lubricant.
摘要翻译： 在滚动轴承中，“呼吸”现象，即主要由于温度环境引起的轴承内部潮湿体积的增加和减少是众所周知的。 鉴于这种现象，（机械）密封件（9）的唇形密封件（9'）将略微但有规则地从其支承件即轴承内圈（2）推出，这导致润滑剂逸出。 为了有效地避免这种泄漏，将具有磁性的第二密封件（5）添加到（机械）密封件（9）中。 该磁性密封件（5）在密封装置（5,9）的密封侧附近设有凹槽（6）和凸起（7）。 由于密封装置的磁性，主要在所述突起（7）之间施加和固定磁性流体（8）。 所述轴承（1,2,3）内的呼吸现在将被所述磁性密封装置（5）弹性地接收，而不影响所述密封唇（9）的功能，从而防止润滑剂泄漏。
