Transient Dynamic Performance and Fatigue Life Analysis of Gear Structure of Shearer Cutting Section
In order to further explore the possible fatigue damage of shearer's cutting gear during operation,this study took MG300/700WD shearer as the object,analyzed two key gears in the shearer's cutting gear drive system,and carried out transient dynamic analysis on them by finite element analysis method,and determined that the stress and strain of the meshing parts of the two gears were relatively concentrated.At the same time,nCode Design Life software was further applied to analyze the fatigue life of the gear,and it was determined that the fatigue life of the gear meshing part was the lowest,about 175d,which was basically consistent with the actual situation.Therefore,the effectiveness of this study was preliminatively confirmed,and it can provide a reference for the follow-up preventive maintenance work of the same type of shears.
