The Edge of Efficiency

Atlanta Gear Works receives grinding wheel assist from Weiler Abrasives

Machines in paper/pulp applications are among the longest and most complex continuous manufacturing machines in the world—some stretch more than 300 yards. Maintaining precise speed ratios across dozens of shop machines is critical for operational success—even the slightest speed mismatch can cause the paper web to break, wrinkle, or stretch unevenly. Gearboxes (combined with variable speed drives) make this coordination possible.

Influence of Tooth Root Contour Deviations on the Tooth Bending Strength

This study investigates how manufacturing-related geometry deviations in the tooth root area affect gear bending strength calculations, demonstrating that accounting for measured tooth contours rather than nominal geometries is essential for accurate material comparisons in fatigue testing.

Water Spray Quenching—A New Intensive Quenching Process for Case Hardening of Gears

Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.

E-Mobility is changing the gear market at an incredibly rapid pace. Software is adapting to meet these new challenges.

Grinding

When grinding steel parts, the surface of the part can "burn" if too much heat is applied in a short time. Grinding burn refers to all those structural changes in edge zones of steel parts that are caused by grinding processes in steels due to the thermal energy introduced. Grinding burn can mainly occur in the form of tempering zones or new hardening zones.

NVH

The arrival of Gleason’s Hard Finishing Cell (HFC) in 2018 represented a paradigm shift in the way automotive transmission gears and gears for e-drives, could be produced in high volumes. Now, for the first time, 100 percent inspection of every gear, and every gear tooth was possible in-process, without impacting the high speeds at which these gears need to be hard finished. Identifying, and correcting for, conditions that create unacceptable noise behavior in these gears, on the fly, was finally a reality too.

Heat Treating

Gas carburizing has been around for a long time. One could argue that gas carburizing is the most common heat treating process. Heat treaters performing gas carburizing are often characterized by a dirty environment, hazy surroundings, and that “smell.” While the product quality may be acceptable, gas carburized parts do come with some challenges, like excessive intergranular oxidation (IGO) or intergranular attack (IGA), which is often ground off. Low-pressure carburizing (LPC) has proven to be a much cleaner and very capable alternative process. Most furnace companies have combined LPC with high pressure gas quenching, which moved carburizing from the dark back room to a relatively “clean room” environment. However, there is still a strong need for oil quenching, which is the common feature of the long used standard integral-quench (IQ) furnace.
