What are the advantages of having my gearbox overhauled at The Gear Works rather than replacing it with a new unit?

Often times, replacement gear units are not sitting on the shelf ready to go and new comparable units necessitate a new installation footprint, a time consuming and expensive process. At The Gear Works, we don't just overhaul gearboxes, we determine whether they can be rebuilt better than new. Our engineering expertise commonly finds ways to improve existing gear trains. If the gearbox has experienced frequent breakdowns, we can help determine why and suggest a remedy. These improvements are often made using many of the existing gearbox components, saving our customers time and money.

Why should I care about heat treat verification?

The proper heat treatment of gears is vital to fulfilling their design life potential, especially with carburizing.

If the case depth is too excessive, the gear teeth can become brittle, leading to catastrophic failure. If the case depth is too light or the hardness is not high enough, the part does not rate as designed, which can lead to premature failure. The Gear Works understand this and that is why we destructive test a coupon with every heat treat load. We perform a hardness and case depth profiles using our state-of -the-art Struers test equipment. All gears carburized by The Gear Works go through this process, so our customers don't have to face the painful costs of downtime.
