Housing and Castings
Castings are rigidly designed and constructed to absorb internal and external loads with minimum deflection. Gear cases are pre-drilled with pilot holes to assist in installation of dowel pins.
Spiral Bevel Gears
Designed and manufactured by Amarillo Gear Company LLC for fan drive service.All spiral bevel gears are precision machined from high grade alloy steel, case hardened and lapped in pairs.
Helical Gears
Helical gears are designed specifically for fan drive service and are precision machined from high grade alloy steel, case hardened and precision ground to provide low-noise, low vibration operation.
Bearings
Amarillo Gear is an industry leader with L10a bearing life exceeding 100,000 hours on all bearings. Input and intermediate bearings provide double the service life specified in AG MA and CTI standards, resulting in lower maintenance costs. The fan shaft bearings are designed to carry all loads imposed by the fan while maintaining this outstanding bearing life. Only trusted name brand bearings such as Timken and SKF are installed in Amarillo fan drives.
Quiet Operation
Quiet operation of the Amarillo Fan Drives is achieved through careful design and controlled manufacturing methods of components.
Shaft Seals
Both the input and output shaft openings have 2 spring-loaded, single-lip seals to keep outside contamination from entering the gearbox.
Lubrication
Oversized slinger on the input shaft provides excellent lubrication in either direction or at half speed operation.
Low Speed Operation
For operation when motor speeds are less than 450 rpm, single reduction fan drives require Amarillo Gear's exclusive KLow Speed" option, and double reduction fan drives require a mechanical oil pump for proper lubrication. The addition of these options allow operation with no minimum input speed restrictions.
Service Openings
Large inspection opening facilitates periodic inspections.
