This invention relates to a cooling system for industrial equipment such as, for example, controlled start transmission gear reducer. The cooling system comprises a fan disposed on the rotatable shaft of the equipment for rotation in either direction and a fan shroud disposed about the fan for directing air currents generated by said fan through a connecting duct to an item or area to be cooled such as clutch. The ducting is connected to said fan shroud by means of an outlet duct which is substantially in the center of the outer periphery of the fan shroud. Disposed within the shroud and pivoted at a point near the periphery of the fan is an air deflector element. A free end of the deflector element is swingable from one side of the outlet ducts to the other side to close off one or the other of the outlet portions of the outlet duct, depending upon the direction of rotation of the fan.
In a controlled start transmission gear reducer having an input shaft and an output shaft and a clutch associated with said output shaft, a cooling system for said reducer, comprising:
