发明名称 DISPOSITIVO PARA MEDIR LA LUBRICACION DE SUPERFICIES QUE RUEDAN O SE DESLIZAN UNAS CON RELACION A OTRAS
摘要 <p>According to the improved system signals related to the oil film thickness and percentage of mechanical contacts between the rolling elements during certain intervals are measured. Therefore the capacity Cb is connected to mass and at the other side to the condensor Cv is coupled to oscillator (6) which output is connected to the first input of a demodulation-circuit (8) comprising a multiplier (9) and a low-pass filter (10). The voltage (Vb) is connected to the second input of circuit (8) which output is connected to an analog/digital computing-system (11).</p>
