  • S1110202 Easy Set-up and In Situ Automatic Gear Diagnostic System Using Laser Beam Reflection without a Rotary Encoder

説明

A method which can diagnose damage on a tooth surface of a gear by using a laser beam without a rotary encoder was developed. This method is as follows: 1) The tooth bottom, the tooth tip and their two medians are found by the derivative values of the laser reflection data. 2) The gear rotation speed is calculated with intervals of these four positions, and each value of the gear rotation speed is interpolated by using spline interpolation to convert them to continuous values. 3) The gear rotation speed values are integrated to gear rotation angle values. 4) The gear rotation angle values replaced the horizontal axis of the laser reflection data, and the laser reflection data is a form in which they can be diagnosed. From the experimental result, the accuracies were similar to the diagnosis data with using our method and the data using a rotary encoder. Accordingly, diagnosing without a rotary encoder is available through the above-mentioned system. Attaching only one laser sensor module, we can diagnose gears automatically in various cases.
