Effect of inconsistent input speed on dynamics of torque coupled gear set in electromechanical short-range cutting transmission of shearer

A compacted cutting powertrain consisting of multiple motors, a torque coupled gear train and a planetary gear train was proposed to avoid the influence of longwall shearers' ranging arm deformation. Dynamic behavior of the torque coupled gear train affects the load carrying capacity and service life of the powertrain. Causes of inconsistent fluctuant input speeds in the torque coupled gear train were analyzed. Effects of the inconsistent input …
