Smart Alloying Eliminates Manufacturing Steps in Automotive Gears

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.

Conjugate Bevel and Hypoid Gears

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.

Design and Load Capacity of Crown Gears in Comparison to Bevel Gears

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.

Analytical Calculation of the Gear Body Stiffness of Face Gears

This paper presents a new analytical method using plate and disk mechanical models to calculate the gear body stiffness of face gear wheels, showing that stiffness decreases toward the outer radius—a behavior that conventional cylindrical gear approaches fail to capture.

Design

Gleason's Coniflex® Pro Design and Manufacturing System for producing stronger, quieter, and more reliable e-drive differential gears in high volumes, for automotive, truck, bus and off-highway transmissions. It‘s the differential difference!


Grinding

From its origins as a small machine shop to becoming a global leader in precision engineering, Gleason Corporation has continuously redefined the industry. This journey, marked by pioneering inventions and strategic expansions, has left an indelible mark on sectors ranging from automotive and aerospace to robotics and renewable energy.

Inspection

Gear inspection has long been a highly specialized, costly investment and an overall challenging part of the gear manufacturing process. Through advances in technology and automation, this typically tedious, time-consuming process is becoming significantly
more efficient as multisensor coordinate measuring machines (CMMs) gain more traction as one of the preferred methods of gear inspection.

Helios Gear Helps American Precision Gear Achieve Quality and Productivity

At American Precision Gear, quality isn’t just a priority — it’s the foundation of everything they do. The shop specializes in high-precision miniature gears for aerospace, defense, and medical applications, where the strictest tolerances are non-negotiable. Helios Gear Products partnered with American Precision Gear to integrate the MZ 1000 D-Drive into their production.

Industry News

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.

Product News

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.
