Most gearbox repair follows a familiar sequence. A unit shows up damaged, the shop measures what’s worn, makes replacement parts, reassembles, and ships it back. Scott Franks, P.E., spent decades inside that world at Lufkin Industries and came to believe it wasn’t enough.
This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.

20NiMo9-7 alloy achieves up to 48 percent higher fatigue strength than conventional carburizing steels in the as-carburized condition, eliminating the need for shot peening and grinding in automotive gear applications.
.
This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.
.
The article proposes a method to optimize cylindrical gearbox tolerances by balancing gear noise performance and manufacturing costs using modeling, analysis, and meta-model-based optimization.

The objective of this paper is to improve the methodology for determining the tooth flank temperature. Two methods are proposed for assessing scuffing risk when applying AGMA 925 for high-speed gears. Both methods provide similar results.
The Swabian transmission and drive solutions manufacturer SPN Schwaben Präzision Fritz Hopf GmbH manufactures gearboxes, gears, and drive systems according to individual customer requirements.
Complete inspection of gear surface finishes at the submicron level became a reality with the introduction of Gleason’s 300GMS nano, in 2022. The new system ushered in an exciting new era in gear inspection. For the first time, producers of EV transmission gears, and gears for other applications requiring very tight tolerances and low noise requirements, could quickly inspect surface finishes and perform extremely reliable noise analysis at submicron levels—benefits that were almost impossible to achieve just a few years ago.
Quality control, EV components, energy consumption and material influences are just a handful of topics being discussed in heat treating today. New heat treat methods and global trends will be the topic of conversation later this year at Heat Treat 2023. Here’s a round-up of some stories circulating across key market segments.
Discover how next-generation bevel gear metrology combines flank form, waviness, surface quality, and root geometry analysis in a single automated inspection cycle. Advanced software and standard probes deliver faster measurements, deeper diagnostics, improved process control, and enhanced gear performance.
Gleason’s new line of high-performance QFS Quick-Flex Segmented Collets are designed for seamless integration with all major workholding systems. Manufactured to the highest standards, they provide exceptional concentricity, durability and clamping force. With their blue vulcanised clamping elements, QFS are a commitment to quality, offering run-out accuracy of ≤5 µm. Put them to the test.
Gleason's Closed Loop System with robot or cobot loading now fully automates the measurement and correction process in gear production. Automatically prompting corrections on connected production machines, the GMSP series not only reduces human error in repetitive tasks, it also increases utilization of inspection equipment up to 90%.
TfG’s RGC 350 Radial Chamfering Machine from Machine Tool Builders produces defined, reproducible chamfers and ‘perfect’ teeth every time. The continuous, high-speed cutting process works wonders even on workpieces with interfering contours. What used to be slow, painful and expensive is now fast, painless, and perfect.
Deburring gears is dusty, repetitive, and hard to staff. The OB7 cobot from Productive Robotics automates it with quick setup and no programming required. Consistent finish on every part, built in the USA. See the full cobot deburring package and request a quote.
The LC 280 DC gear hobbing machine from Liebherr is designed for precise gear cutting up to module 4.5 mm. It combines high productivity with advanced technology, featuring simultaneous FlexChamfer for efficient deburring and chamfering during the hobbing process.
Forest City Gear announced the retirement of Jeff Mains, Director of Technical Operations, following many years of dedicated service and leadership within the company. Mains’s transition from his full-time role went into effect on Friday, May 29.
Rego-Fix USA will showcase its advanced toolholding solutions for manufacturers seeking enhanced precision, repeatability and reliability in their machining processes at IMTS 2026 from September 14-19 at McCormick Place, Chicago, Illinois, in Booth #431822. The company will feature the original ER collet and its patented powRgrip toolholding system. Also on display will be an Ed Carpenter Racing (ECR) racecar, symbolic of Rego-Fix’s ongoing sponsorship for the upcoming 2026 NTT IndyCar Series racing season.
