A technical overview of the three principal face couplings (Hirth, Coniflex, and Curvic), comparing their tooth geometries, self-centering behavior, and Gleason’s cutting and grinding processes for manufacturing them.
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.
.
This excerpt from Gear Technology Solutions explains how oversized cutter blade edge radii cause root interference in bevel gears, and how to select correct radii to avoid noise, flank damage, and tooth fracture.
.
Through loaded tooth contact analysis of two applications, this paper demonstrates that crown gears can match bevel gear load capacity while offering meaningful advantages in weight reduction, axial-force-free pinion mounting, and assembly simplicity.
.
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.
.
The aim of this report is to investigate the potential of using surrogate models within the gear design process.
When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.
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.
The demand for double helical gears in planetary gear systems for engines in the civil aerospace industry is increasing. Innovative grinding processes and state-of-the-art technologies ensure precision, reduced weight, and improved cost efficiency. Learn how KAPP NILES reduced the gap width from 30 mm to 15 mm.
Discover four diagnostic enhancement tools that move RX® endothermic gas atmosphere generator operations from preventative to predictive maintenance. Learn how monitoring dew point by retort, comparing equal flow, tracking tube performance, and measuring outlet temperatures prevent costly failures while ensuring consistent, high-quality carrier gas production.
The right hob can make a measurable difference in gear production. Watch the video to see how Star SU combines advanced hob technology with application expertise to help manufacturers get more from every gear cutting operation.
The Intra SFTX twin-spindle single-flank testing system is engineered for advanced gear quality testing and NVH analysis of demanding e-drive gear applications. Combining Transmission Error (TE) and Torsional Acceleration (TA) measurements, it delivers fast, precise diagnostics and detailed order analysis, quickly identifies critical gear issues, enhances traceability, and helps prevent costly defects from reaching end-of-line (EOL) testing.
The 80PS Power Skiving and Hobbing Machine is specifically engineered for power skiving, hobbing, and profile milling of small internal and external gears. Configured specifically for the demands of humanoid robotic gear production, it delivers outstanding performance and process stability for gears used in strain wave, planetary, and cycloidal gearboxes, as well as other high-precision applications of comparable size — even when machining fine-pitch gears and thin-walled components.
At Gear Headquarters, quality is the foundation of everything they do. Based in Kansas City, the shop manufactures spur, helical, double-helical, herringbone, bevel, internal, spline, and worm gears, sprockets, and timing belt pulleys.
New orders of metalworking machinery, measured by the U.S. Manufacturing Technology Orders Report published by AMT – The Association For Manufacturing Technology, totaled $605.8 million in July 2026. This was an 8.0% decrease from June 2026 and a 55.2% increase over July 2025. This is only the second time since USMTO began collecting data in 1998 that orders have exceeded half a billion dollars for five consecutive months. Through the first seven months of 2026, manufacturing technology orders totaled $4.03 billion, a 37.1% increase over orders placed through July 2025.
In most precision shops, the print is clipped to the bench, the setup sheet is in someone’s email, and the operator walks back to the office to confirm they’re on the right rev. That’s one of the problems Datanomix is solving at IMTS 2026. Datanomix will showcase Digital Production Bundles at IMTS 2026, Booth #135521, and prove what happens when the shop floor goes paperless.
