Abstract A method based on vibration signal is introduced for evaluating the spall size of rolling ball bearings, which utilizes the interval measurement of the double impulses generated by the spall and the rotor speed of the bearing mounted shaft. However, the measurement of the rotor speed is not convenient in some real working conditions. To address this issue, a method based on double impulses is proposed without a speed meter. The rotor-speed estimated by counting the number of impulses in a full rotating cycle of the shaft. By combined the rotor speed and average double-impulses intervals, the new method realizes the spall size estimation without the speed meter. It is appropriate for engineering applications. Experimental results indicate that the proposed method is valid.
