Perceive, Understand & Perform

AICA and Schaeffler demonstrate the role Physical AI can play in the manufacturing environment

Conversations on the role Physical AI will play on shop floors across manufacturing took place at every stop I made during the Automate Show in Chicago. Robots—in addition to literally doing the heavy lifting—are now being asked to independently learn from experiences and discover solutions without the assistance of human programmers. At the Universal Robots (Teradyne Robotics) booth, I was treated to some amazing force sensing applications that led to a discussion on a recent gearbox assembly use case between AICA (a partner of UR) and Schaeffler that tapped robots to assemble gearboxes.

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.

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.

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.

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

Mechanical power loss in gears is generated through sliding and rolling of the contact resulting in frictional work and elastic hysteresis generation of heat. This action is both a parasitic loss of energy from the drivetrain and a source of engineering costs to control system temperature to avoid heat-related failures of the gearbox components. Therefore, from both a cost and durability standpoint it is of great interest to minimize the frictional losses at the gear tooth contact interface.

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.

Inspection

Zahnradfertigung OTT GmbH & Co. KG was the first company to install the new fully automatic CNC-controlled P 152 precision measuring center from Klingelnberg in its ultra-modern machine park.

Heat Treating

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.
