Cooling Tower Gear Box

Welltech Cooling Towers has already manufactured several sizes of gear boxes for cooling tower application which are designated as KBVCT. 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.Gearboxes are used as speed reducers to slow the rotational speed from the incoming motor to the outgoing fan of a cooling tower. Companies that operate high-capacity production plants, such as those in the power industry, require cooling towers with large amounts of heat rejection capacity.Without gearbox technology, cooling tower motors would be massive to directly handle the torque required by the fan. Something so large and heavy would be too expensive and impractical.


  • Case Hardened And Lapped Steel Spiral Bevel Gearboxes Are Provided For Torque Transmission Between The Right Angle Shaft.

  • Our Cooling Tower Gearboxes Have A Unicast Case, Three-Point Foundation With Pump Less Lubrication, Which Is Unique In Design.

  • It Has A Combination Of Labyrinth Double Oil Seal Arrangement At Fan End With Double Oil Seal At Motor End.

  • Taper/Cylindrical/Spherical Roller Baerings Are Used.
  • The Standard Direction Of Rotation Is “Clockwise” At Both The Input/Output Shafts When Viewed Onto Respective Shaft End.
