ABSTRACT This article describes the measurement of lubricant film thickness distribution in a roller bearing by using two juxtaposed transducers, which are excited by a new ultrasonic pulse receiver with a maximum pulse repetition rate (PRR) of 100 kHz. The experimental results demonstrate the feasibility and advantage of this method with high PRRs. The influence of rotating speed and radial load on the measured film thickness are shown to be consistent with the theoretical predictions. Skewing of the roller in the bearing is observed. A combined trigger signal is proposed to reduce the influence of the cyclical vibration of the rotor.
