摘要： A longwall shearer or other machine with a gear case for transmitting rotational power from a drive to a driven member. The gear case comprises a drive, a driven member, at least one axle including at least one aperture formed therein to circulate cooling fluid through the axle, and a gear mounted to rotate on the axle and positioned to transmit power from the drive to the driven member.

摘要： A cooling system for the gear case in the ranging arm of a longwall shearer, the ranging arm including a plurality of single gears mounted in a row within an elongated housing. The cooling system includes a coolant injection system in each of the single gears, each coolant injection system including a longitudinal opening in the gear axle, and a coolant injection tube mounted inside the longitudinal opening. The coolant injection tube has a diameter smaller than the diameter of the longitudinal opening. A coolant supply line is connected to and in communication with the coolant injection tube, and a coolant outlet is connected to and in communication with the longitudinal opening adjacent the one end of the longitudinal opening, so that coolant leaving the end of the coolant injection tube travels back along the coolant injection tube and then out of the gear axle thereby removing heat from the single gear.
