Analysis of Shearer Gear Vibration in the No-Load State

Analysis of cutting gear mechanical structure of embedded electrical traction shearer is description, introducing independently developed high-capacity data logger embedded Shearer, by which collecting empty state Shearer rocker shaft attachments vibration acceleration signal. By the method of vibration analysis, acquire characteristic signal frequency from gear drive at all levels in the health status of shearer to provide contrast reference data, for accurate identification of the shearer late underground cutting coal and rock conditions and fault diagnosis.
