Abstract

By taking the gear box of a ship lock’s hoisting machine as the research object, because of the vibration signal of a fault gate has the characteristics of both randomness and non-stationary, the chaos oscillator detection theory is introduced into the diagnosis for gear fault. Research the dynamic behavior of the gear under different condition of various revolving speed and fault parameters based on the vibration model, analyze the variations of the change of phase trajectory of the gear oscillator by through the bifurcation diagram, phase diagram, power spectrum and time histories, the fault of the gear could be diagnosed. The method has been verified effectively to extract the early fault of gear box by inspection, solved the poor effect by spectrum analysis as the lower frequency response because of the shock by the low speed, the failure point, a new method for the low speed and heavy duty gear box fault diagnosis has been proposed
