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.

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.

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 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.

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.

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

This article introduces the process of polish grinding of gears. Improved surface quality increases the overall efficiency of gearboxes, resulting in reduced friction and torque loss, higher power density, and noise-optimized gears (lower NVH); all these factors are highly relevant, especially for electric drives. When Reishauer developed polish grinding in 2012, the process aimed to improve the efficiency of ICE engine transmissions, and the set goals were easy to achieve. Today, in 2023, the situation is dramatically different. While an ICE engine operates at around 3,000 rpm and supplies acoustic masking of the gear noise, EV drivetrains feature up to 20,000 rpm and offer no such masking.

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.
