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.
An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld exploring the mathematics behind conjugate bevel and hypoid gears—from the fundamental laws of gearing and the conditions for perfect conjugacy to why real-world power transmissions require deliberate crowning rather than theoretically exact conjugate designs.

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 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.

For cylindrical gears, speed-increasing transmission stages are well known, and regarding profile shift, preferred pressure angles, and helix angles a set of rules applies, which is not much different from the rules for speed reducers. It is important to acknowledge that basically, a speed increaser has to be designed just like a speed reducer, but then the gear with the lower number of teeth is the output. Of course, the torque and the speed of the gear with the lower number of teeth (output) and the gear with the higher number of teeth (input) must be the same as if this transmission was used as a speed reducer. In the case of straight bevel gears, spiral bevel gears, and hypoid gears the same rules apply with some additions. Spiral bevel gears have many applications as speed increasers.
This article describes a cloud-based process and machine component monitoring system called ARGUS. The term “swarm” is used for a large population of gear-grinding machines of individual and independent customers connected to the ARGUS system and the ARGUS cloud. These “swarm” machines permanently feed their anonymized process data into a common cloud database. Reishauer uses this database for big data analytics to discover patterns that indicate successful process and machine component behavior patterns worth integrating into the ARGUS algorithms and propagate them across the complete ARGUS customer base.
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.
By understanding customers’ manufacturing and heat-treatment processes, Ipsen identifies pain points and develops IIoT and AI-driven solutions that improve operational efficiency.
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.

This white paper explores how the use of an automatic tool change system can boost productivity in the grinding process. When manufacturing large gears, the demands regarding surface quality of the ground tooth flanks are increasing.
Marposs presents its latest innovations in precision measurement and quality at Control 2025. Marposs technologies support advanced manufacturing processes and ensure the highest standards of accuracy and reliability.
Under the umbrella of Aiktec – Digital Solutions, Klingelnberg brings together smart, industry-ready applications that bring the concepts of Industry 4.0 and the IoT directly to the shop floor. Smart Tracing is a web-based software solution for analyzing machine behavior. It is essentially the Klingelnberg DDQM (Data-Driven Quality Management) for any CNC machine, regardless of the manufacturer. Relevant process and performance information from the CNC machine is uploaded in the form of servo traces and managed and analyzed via a simple browser application.
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.
