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.

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.

The Intrinsic Pitch Cones in Hypoid Gears

A method to calculate pitch cones for hypoid gears using macrogeometry parameters—similar to non-offset bevel gears—while accounting for the added complexity of hypoid offset, tooling, and cutting technology is explored in this paper.

Design

In modern automotive vehicles, gear noise becomes more and more of an issue. The main reason is the reduced masking noise of the engine, which vanishes completely in the case of an electric driveline. Improved gear quality unfortunately does not correlate with a better noise performance in any case. High gear quality makes sure that the gear flanks are inside tight tolerances and that all teeth are nearly identical. Even if the running behavior of such gear sets shows a very low sound pressure level, the noise perception for human ears may be annoying.

Grinding

When you talk with Jared Lyford, director of operations at Forest City Gear and the newly appointed president of the Rock River Valley Tooling & Machining Association (RRVTMA), it becomes clear very quickly: workforce development isn’t a program for him. It’s a calling—and one shaped by lived experience.

Inspection

In conventional gear manufacturing, quality control is carried out for a number of pieces per batch. Most parts enter final gearbox assembly without any inspection. Among other things, this approach is based on two facts: measuring time is significantly longer than the machining time, and the limited measuring capacity available.

Heat Treating

Various in-situ methods can track realtime heat treatment response in bulk materials. This can aid material engineers in designing the most effective heat treatment procedures and processing methods. In-situ  methods such as thermogravimetry (TG), differential thermal analysis (DTA), and dilatometry, offer capabilities to examine heat treatment behavior in real time, giving insight into the thermochemical mechanisms and the thermal behavior of steel.
