Fault detecting panel of high speed wire rolling mill gearbox

Abstract

The gear box fault detecting board for high speed wire rolling mill has one sensor to sense related vibration, one signal processor to receive the vibration signal from the sensor for amplification and processing, one demodulating converter connected to the signal processor to separate a demodulated signal from the AC vibration signal, one low frequency vibration separator also connected to the signal processor to separate 0-500 Hz low frequency vibration signal corresponding to the rotation speed, and one computer AD interface to receive signal from the demodulating converter and the low frequency vibration separator for sampling, analysis and diagnosis. The gear box fault detecting board of the present invention can collect and analyze the low frequency vibration signal and fault signal from the gear box of high speed wire rolling mill for further computerized analysis.

Description

technical field [0001] The invention relates to a fault detection device for a gear box of a high-speed wire rolling mill. In particular, it relates to a demodulation signal detection device for low-frequency vibration and fault impact of a high-speed wire rolling mill gearbox. Background technique [0002] Due to the complex environment of high-speed wire rod mills and serious mechanical and electrical interference, many useless interferences are superimposed on the signals detected by the acceleration sensor. If these interferences are not filtered out, the spectrum analysis will be affected, because the frequency of these interference signals is relatively high The frequency of normal vibration signal is high, and the method of low-pass filtering is usually adopted. However, after low-pass filtering is used, some shock signals that reflect fault information are also filtered out. The frequency of these shock signals is often much higher than that of normal vibration sign...
