Gear Box Repair/Rebuild
Gear Reducer Failure

Gear reducer failure is a serious problem which is why gearbox rebuild and repair is such an important part of what Delta Dynamics does. This reducer, pictured on the left, was designed and built by another machine shop to handle the increased horsepower that an Aluminum Smelter wanted to put through it. The gears lasted two weeks. 

The experts at Delta Dynamics were able to analyze the situation and perform industrial gearbox services. The large-width gears were theoretically capable of handling very high horsepower. However, the large torque in the system wound up the pinion shaft so that the actual gear contact length was much smaller than designed. With our help, gear reducer failure problems will be minimized and eliminated so that your machinery may work as it is intended to.

As shown in the image on the left, Delta Dynamics built a set of gears to replace the failed helical set above. The double helical design eliminates all thrust loads on the bearings which really emphasizes the strength and power of gearbox rebuild and repair, as the bearings were one of the constricting factors with the increased horsepower. The double helical design with axial float on the pinion allowed full-face contact regardless of the torsional windage. The gear reducer has been running for well over 6 years without any concern.

Delta Dynamics can build a new set of gears in an old housing, painted to your specifications with all new hardware and plumbing, without a "new" price. This box, pictured on the left, was rebuilt in less time than it would take to cast a new housing and met all customer requirements.
