Custom Gearboxes

Gearbox windage and oil drainage receive special attention during the design and development phases to reduce parasitic power loss. Calculations are performed to estimate the loss and optimize clearances between the rotating components and the housing. BNI has special expertise in this area and has helped several clients reduce parasitic power losses in their gearboxes. 

Bearing selection and design are critical for successful gearbox design. Bearing selection is performed concurrently with gear design to ensure proper bearing load capacity and gear alignment. Antifriction or fluid film bearings can also be used.

Barber-Nichols, Inc. (BNI) has been engineering, manufacturing, and testing custom gearboxes since 1969. BNI develops spur, helical, and worm gears in accordance with American Gear Manufactures Association (AGMA) 2002 standards. In addition to oil, Barber-Nichols has experience using unorthodox lubricants such as light hydrocarbons, refrigerants, and water at pitch line velocities up to 125 m/sec (417 ft/sec).
