Strain Wave Gear Production in the Age of Humanoid Robots

Humanoid robots need precise strain wave gears in their joints, and building and inspecting those gears at scale will call for equally advanced production technology

“The time has come for robots,” Nvidia CEO Jensen Huang proclaimed at his company’s annual GPU Technology Conference in March 2026. “Everyone, pay attention. This could very well be the largest industry of all.”

The Near Future of Mechanical Drive for Humanoid Robots

AI has moved humanoid robots forward, but safety, reliability and cost in the actuator drivetrain still stand in the way of commercial deployment

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 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.

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

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes

Inspection

In the present paper, a spline-joint design and the extension of a back-to-back test rig were presented, which enable the testing of crowned spline-joints under high rotational speed, medium torque, high test temperature, and angular misalignments.

Heat Treating

Furnaces North America 2022 (FNA 2022), presented by the Metal Treating Institute (MTI), in partnership with its media partner, Heat Treat Today, is the heat-treating industry’s go-to event every other year. FNA 2022 attracted attendees from across North America, including Fortune 500 companies. For three days attendees took part in networking, connections, and learning about the vast changes taking place in emerging technologies, industry trends, and advances in equipment.
