The Gear Works

With a reputation built on 60 years of success stories, The Gear Works continues to grow with the introduction of its well-equipped new Gearbox Repair and Test Facility.

While it might not seem logical at first glance that a degree in journalism would lead to a career in gear manufacturing, it all begins to make sense once you’ve heard the story. “Ingwald Ramberg was the son of Norwegian immigrants who settled in Seattle around the turn of the last century,” says Roland Ramberg, […]

The Whirling Process for Internal Threads

With the advent of “internal whirling,” Leistritz has introduced an innovative new way to machine internal threads, thereby increasing efficiency, productivity, and quality.

As an industry leader in the field of whirling technology, Leistritz has developed an innovative solution to machining difficult internal threads. The process, which is called “internal whirling,” can be performed in both soft material using carbide tooling and in steel as hard as 65 hrc with CBN. In each case the process is performed […]

A New Tool Steel for Hot Forming Gears

The need for a high hardness, wear resistant die steel for hot forming has gone largely unanswered–until now, with the advent of CPM 1V.

Hot forming operations like forging, extrusion, hot upsetting, piercing, and any other operations involving deformation of solid hot metal place difficult demands on tool steels. The operating environment is above about 600ºF (320ºC), and may often exceed the heat treating temperatures of traditional tool steels. Tools and dies may typically be required to run at […]

Profile Relief and Noise Excitation in Helical Gears

The microgeometry of mated teeth is at the core of excess noise in helical gears. Here are the latest findings from The Ohio State University’s Gear Dynamics and Gear Noise Research Laboratory.

Gear noise results from the gear mesh dynamic forces that are transmitted through the support shafts and bearings to the gear housing. There are many sources of these forces, with the most important of these being predicted by analyzing the mechanics of the meshing process. It is important that this analysis takes into account the […]

Terry McDonald: Site Safety

An official safety manual is an important part of any company’s safety strategy, but where to begin? Read on to learn how to start the process.

Tooth Tips: Andy Milburn, P.E.

Previous columns have discussed gear misalignment, but since it's responsible for so many problems and generates a lot of questions, the topic deserves more explanation.

A frequently asked question is "How good does the alignment have to be?" This column and the next will attempt to answer that question. In many cases, the allowable gear misalignment is less than what you might expect. More gearboxes are being manufactured with surface-hardened and ground gears with a much higher load per square […]
