METAL’s Manufacturing Workforce Network

A DoW-funded partnership brings online courses and hands-on bootcamps to Purdue’s foundry lab, training that feeds gear production

Many students and job seekers are unfamiliar with the advanced technologies and career opportunities available in metal casting and forging. But thanks to the Metallurgical Engineering Trades Apprenticeship and Learning (METAL) program, led by the IACMI-The Composites Institute, that is changing. METAL is partnering with universities to showcase the rewarding careers these industries offer. Together, these institutions are hoping to revitalize American manufacturing by delivering responsive, scalable, and sustainable workforce development programs.

Root Interference

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.

Design Principles of Bevel Gears: Rationale for Zero Sum Profile Shifts and Generating Gear Choices

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.

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.

Water Spray Quenching—A New Intensive Quenching Process for Case Hardening of Gears

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.

Design

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.  

Grinding

From the outside, Gallmar Industries, nestled into an Oshkosh, WI, neighborhood, looks like any unassuming, medium-sized gear shop. Then take a plant tour with Gallmar’s VP of Operations Kenan Zolota—and prepare to be amazed. The facility stretches on like the Army’s warehouse at the end of Raiders of the Lost Ark, with everything from gear cutting to heat treat, gear grinding to inspection, all under one roof. Gallmar’s breadth of product line is in evidence too: defense-related transmission gears, 60-in. diameter internal gears for mining equipment, axle components for fire/ rescue trucks five feet in length, right down to a bin of brass ammunition casings that Zolota says are a special order.

Skiving Tools

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.

Heat Treating

The roots of heat-treating run deep within ASM (American Society for Materials) International, as its society was founded in Detroit in 1913 as The Steel Treaters Club. The heat-treating constituency of ASM created the Heat Treating Society (HTS) to provide focused leadership, communications, and service development to its network of worldwide membership of captive and commercial heat treaters, equipment manufacturers, researchers, governments, and technicians. To discuss Heat Treat 2023, the 32nd annual HTS Conference and Exhibition, Gear
Technology took a moment to catch up with conference chair Andrew Banka, vice president of Airflow Sciences Corporation. Heat Treat 2023 is colocated with IMAT and Motion + Power Technology Expo in Detroit, October 17–19.
