New England Gear

Celebrating 20 years in the business of remanufacturing late-model CNC Fellows gear shapers, New England Gear attributes its success to excellent customer relationships, a wealth of technical knowledge, and superior standards.

It’s not often that you call a company, even a small one, and get the owner on the other end of the line. But when Gear Solutions called New England Gear to offer congratulations on its 20th anniversary this year, it was Jeff Barnes, founder and sole proprietor, who answered the phone. This personal relationship […]

A Comparison of Wrought Steel Gears and Surface – Densified Powder Metallurgy Gears

There is potential in using powder metallurgy transmission gears that match the performance and accuracy of machined gears when fatigue properties and dimensional precision capabilities are compared.

Automotive transmission gears are responsible for transmitting torque from the engine to the wheels. In the process of transferring torque, gear teeth are subjected to cyclic loading. The cyclic loading in turn translates into cyclic tooth bending stresses along the root fillet and cyclic contact stresses on the active tooth surfaces. Historically, high-quality wrought steel […]

Meeting More Demanding Requirements for Removing Burrs: Optimizing Deburring Processes with Innovative Solutions

Burrs and chips are unavoidable in virtually all manufacturing processes used for series production, and today, the removal of these remnants from the production process is an absolute must for high-quality, precision parts.

Whether parts are manufactured by means of machining, metal forming, or master forming, deburring usually doesn’t fall into one of the part manufacturer’s areas of core competence. Thus, the removal of these remnants from the production process is often still seen as a necessary evil that increases unit costs. However, due to ever-stricter requirements for […]

Reducing Gear Noise While Improving Performance

Gear noise reduction can be achieved through electrochemical machining, which is a process that accomplishes metal removal by dissolution of surface atoms without direct contact between the tool and workpiece material.

To protect human health and the environment, noise emission from road vehicles is limited by legislation. In Europe, essential noise limits continue to be defined by Directive 70/157/EEC and its numerous amendments. According to the Brussels-based advocacy organization Transport & Environment, traffic noise is one of the most widespread environmental problems in the European Union. […]

History of Bending Fatigue Part V

The confidence that engineers can put into historical published fatigue data must be proportional to the empirical choices, discipline, and control used in the testing.

In this succession of papers, we have looked at the history, failure life models, and the impending factors that contribute to bending fatigue. The thesis of this series is that there are many factors to evaluate in terms of individual contribution for diminishing design life in gearing and rotating components. And it must be done […]

Making Time to Work on Your Business

In gear manufacturing, the key to making more money is to start working on — not in — your business.

I’ve been involved in manufacturing since I was in high school when I was working part time at my family’s gear business. Since then, I have learned a lot of things: some from my co-workers, a lot from my father, and more from our customers and other business owners. One very important lesson I learned […]

Brazing as a heat-treating process

Brazing is a genre of heat treating that doesn’t receive a lot of attention unless it’s related to aerospace or commercial aviation. However, a myriad of items like chain saw clutch housings, lawn mower parts, stainless steel heat exchanger, and dozens of commercial components contain assemblies that have copper-brazed components. Brazing is the process of […]

Trend Talks: Anna Claire Conrad

As the baby boomer generation continues to grow, so does the need for high-quality medical equipment, a demand in which gear manufacturers play a key role.

According to a release by the U.S. Census Bureau published earlier this summer and to the new estimates released at that same time, there are currently 75.4 million baby boomers, or people born after World War II, in the United States. Additionally, the nation’s 65-and-older population has grown from 44.7 million in 2013 to 46.2 […]
