[0002] At present, most of the cutting parts of domestic high-power electric traction shearers adopt the forced cooling method of the casing water jacket. Although this cooling can play the role of spraying and dust reduction, it is very effective in cooling the oil pool in the gear chamber. Small, because the shell of the cutting part of the shearer is cast steel, its safety strength should be considered in the design, so the minimum safe thickness of the inner wall of the shell water jacket and the inner wall of the gear cavity is more than 50mm, and the heat conduction effect of 50mm thickness It is not very ideal, so this is also the main reason why the temperature inside the gear cavity of the cutting part of the high-power electric traction shearer is always high
