irrigation gearbox

Finally, we also control the standard of every component and each part of the manufacturing process. A dedicated team of buyers, engineers, quality inspectors and machine operators works day and night to ensure each component satisfies the stringent Valley quality requirements. Because our suppliers are positioned in america, we can simply perform random inspections of their facilities to ensure they are conference our quality irrigation gearbox standards. All major components are also machined by Valley, providing another quality level control. A final inspection is performed by testing each gearbox before it really is shipped. And, to further make certain Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.

But, even the best gear design and materials won’t help if the gearbox isn’t sealed from the components. That’s why Valley runs on the patented six-barrier insight and nine-barrier output seal to keep oil in and problems out. To compensate for this longer shaft, special tires are used that truly move the center of the tire closer to the gearbox result bearing compared to the industry standard, reducing the load on the gearbox.

Valley also uses U.S.-made, case-hardened bearings made from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides excellent wear characteristics while maintaining the internal toughness of the primary material. Consequently, Valley bearings possess a 40 percent higher load rating.

The Valley gearbox also offers a 52:1 gear ratio. This means the gearbox uses 4 percent much less energy to move the device through the field, but, moreover, the design includes a fully recessed tooth action. With a completely recessed style, the gears maintain lubrication oil between the gears longer, reducing friction for increased load capability and longer life.
