Detrended Fluctuation Analysis and Hough Transform Based Self-Adaptation Double-Scale Feature Extraction of Gear Vibration Signals

<div>The representative vibration signal, power spectrum, and the DFA curves obtained from the two types of gears with a rotation speed of 985 rpm: (a) Signal from a “Normal” gear. (b) DFA from a “Normal” gear. (c) Signal from a “Toothless” gear. (d) DFA from a “Toothless” gear.</div>
