SPX Cooling Technologies introduced a new line of gearboxes, the Series M Geareducer. Series M Geareducers are designed and manufactured to directly and easily replace other OEM gearboxes in field-erected cooling towers, said company officials.
The Geareducer’s primary function is to reduce the speed of the electric motor to optimize fan performance. This gear drive goes beyond the American Gear Manufacturers Association (AGMA) requirements to maximize air movement through the cooling tower and to minimize maintenance. It provides primary support to the fan, anchors it against lateral movement, withstands shock loads at start-up and during speed changes, and minimizes power transmission losses and noise generation.
The company also said the M series features gears of high strength, case-hardened alloy steel machined to AGMA Quality Class 9 and above. It is designed to fit into non-Marley cooling towers for easy replacement and has heavy duty double row interstage bearings for 100,000 hours of life or more. To further extend service life, it is fitted with large oil passageways to help maintain lower oil temperatures.
The new Geareducer operates without need for oil pumps, oil filters, or oil coolers. It runs with two-stage gear reduction for efficient power transmission and the external cooling fins maximize the surface area for cooler
operation.
