Gear inspection and noise analysis are essential for ensuring quality and efficiency in modern gear manufacturing. Increasingly stringent requirements on dimensional tolerances—often in the micron range—and noise, vibration, and harshness (NVH) performance necessitate advanced measurement and evaluation methods.
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.

The conjugacy of meshing gears is one of the most important attributes of gears because it ensures a constant velocity ratio that gives smooth, uniform transmission of motion and torque. Some of the world’s greatest gear theoreticians like Earle Buckingham, Wells Coleman, and John Colbourne laid the foundation for understanding conjugacy. Their teachings and interpretations of the law of gearing have been used by generations of gear engineers to design and manufacture gear transmissions for almost everything that is mechanically actuated.
The trend towards hard fine finishing of gears for automotive transmissions is accelerating. In recent years, the focus has been on increasing the efficiency of gears in order to make optimum use of the narrow gear ratio range, gear by gear, and to reduce fuel consumption. Surface finish, in particular, is under increased scrutiny since it plays such a decisive role in achieving the noise and efficiency requirements of gear units for today’s EV applications.
Klingelnberg recently invited customers to its first Open House in Saline and the two-day event did not disappoint. Customers from major automotive, off-highway, construction and agriculture OEMs attended a morning of technical presentations before heading into the showroom to learn more about Klingelnberg’s latest machine tool technology.
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.
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.
Download the whitepaper to learn how lifecycle management improves tool performance, reduces downtime, and drives measurable cost savings.
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.
Productive Robotics sets the new standard for simplifying robotic automation. OB7 ensures simplicity in use and versatility, easy automation of existing production and new set-ups, increased output, consistency, and quality. It emphasizes teaching the robot rather than programming. Productive Robotics' OB7 collaborative robots are currently used in many diverse applications due to their simplicity, capability, and affordability.
