Gear Fatigue Life Analysis of the Gear Transmission System of the Cutting Section of Coal Mining Machine
Taking MG132/320-WD coal mining machine as an example,a method of fatigue life analysis of gears in the gear transmission system of the cutting section of coal mining machine based on finite element analysis is introduced.Firstly,the finite element model of the gear is constructed based on the specification size and material properties of the coal mining machine,and then the transient dynamics and fatigue life characteristics of the finite element model of the gear are analyzed to determine the weak point of the gear,so as to provide support for the optimization of the design of the gear transmission system of the cut-off part of the coal mining machine,and to ensure that the gear transmission system plays a maximum role in the operation of the coal mining machine.
