Cooling Tower Gear Box

Elecon has already manufactured several sizes of gear boxes for cooling tower application which are designated as KBV-NL. These are two stage gear boxes having 1st stage out of spiral bevel pair duly case hardened and lapped with another helical pair with case hardened and ground. Normally output shaft is vertically upward which takes the dynamic thrust of fan as well as dead weight of the same by virtue of thrust bearing which is provided in the gear box.The gear box body is out of C.I. and the top bearing as well as gear meshing is lubricated by a built on Pump. The pressure gauge and pressure switch is provided for monitoring the pressure and remote sensing.It is preferable to have stainless steel piping for lubrication as well the hermetically sealed vibration switch as the gear box is working inside the cooling tower. The rating and size of these gear boxes are as per Elecon catalogue No. 122/2/G89.
