    • A lubricating film thickness measuring system and method includes a rolling element bearing (14) having relatively rotatable electrically insulated inner (20) and outer races (26) forming a raceway therebetween. Rolling elements (22) are moveably mounted in the raceway. Apparatus (42,44) is provided for measuring capacitance across the bearing (14). The measuring apparatus includes an oscillator circuit (42) and a phase detection circuit (44) and is responsive to a phase angle shift between a first signal going from the oscillator circuit to the bearing (14) and from the bearing to the phase detection circuit, and a second signal received by the phase detection circuit directly from the oscillator circuit.

    • It is well-known that grease over-filling of a bearing housing provides a strong rise of the normal running temperature of the bearing. In order to avoid this problem the grease surplus has to be drained out through an escape hole of the housing. On the long run this leads also to a harmful loss of useful base-oil from the lubricant. The claimed design overcomes this problem by applying a thermally controlled grease escape valve (6, 12) in the escape hole of the housing (1). This valve (6, 12) opens when an undisereable rise of temperature occurs and closing itself when the temperature drops to an acceptable level. Preferably the valve (6, 12) is controlled by a temperature-­memory-spring (10) which releases itself only when the surrounding temperature exceeds a threshold value.
    • 众所周知,轴承座的润滑脂过度填充提供了轴承正常运行温度的强劲上升。 为了避免这个问题,油脂过剩必须通过外壳的排泄孔排出。 从长远来看,这也导致润滑剂中有用的基础油的有害损失。 所要求保护的设计通过在壳体(1)的逸出孔中应用热控制的排油阀(6,12)克服了这个问题。 当温度下降到可接受的水平时,不可见的温度升高,阀(6,12)打开。 优选地,阀(6,12)由仅在周围温度超过阈值时释放自身的温度记忆弹簧(10)控制。
