Design and Research of Heat Dissipation of Shearer Rocker Arm under Severe Fully Mechanized Mining Conditions
Briefly described the calculation of the thermal power of the rocker arm in the design process of the shearer under the constraints of large working inclination angle,hard coal rock hardness,high cutting power,and compact structure in severe fully mechanized mining conditions.Analyzed the thermal power calculation,heat dissipation path and thermal equilibrium point of the rocker arm simplified into a complex gearbox in this working condition,proposed a heat dissipation design scheme for improving the internal structure of the rocker arm and adding an external cooling device,and verifies the feasibility of the scheme that the cutting thermal equilibrium temperature of the rocker arm does not exceed 90℃under full load test conditions.
