The Motion + Power Technology Expo (MPT Expo) returns to Detroit from October 21–23, 2025, colocated with Heat Treat 2025, creating one of North America’s most comprehensive gatherings for mechanical, fluid, and electrical power transmission, materials processing, and thermal treatment technologies. This year’s events bring together engineers, researchers, technologists, and decision-makers from across industries to explore, connect, and advance the design, production, and integration of cutting-edge systems that keep modern manufacturing moving.
This paper examines the transition from internal combustion engine (ICE) vehicles to electric vehicles (EVs), highlighting the distinct gear design requirements for each and presenting a comparative case study of gearbox configurations in a 14-ton commercial vehicle.

This study explores the failure mode morphology of FZG-A test gears. It aims to examine the orphologies of scuffing, scoring, scratches, and polishing using high-magnification light optical microscopy (LOM) and scanning electron microscopy (SEM) images.
.
This work aims to demonstrate the potential benefit of applying nanocomposite coatings to gear teeth to reduce operating friction and wear by presenting tribological test data.

High-performance plastic gears are increasingly replacing metal gears in several applications due to the many advantages they exhibit. The main ones are lower weight, no need for lubrication, cheaper mass production, significantly better noise, vibration and harshness (NVH) behavior and chemical/corrosion resistance. Most plastic gears are produced by injection molding, which enables great design flexibility, e.g., joining several machine elements into one molded part, while gear geometry modifications like enlarged root rounding or altered profile shapes are also possible (Ref. 1).

The toothed belt and pulley system known by the designation T, which has been selected as an example within this paper, was developed in the 1950s and standardized first in DIN 7721 (1977) and then in ISO 17396:2014. In this case study, the authors check if a single hob can properly cut T5 profile pulleys with 25 and 30 teeth—and if
so, define the range of the number of teeth covered by this hob.
Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector.
Different component characteristics in electric vehicles lead to higher noise and load requirements in the automotive industry. E-mobility—to a certain degree—is changing how gear analysis and inspection is carried out. Dissecting noise issues in gears and gearboxes requires an analytical approach like a detective. The problem could stem from the design itself, tolerancing or tip/root relief issues, tooth flank form deviations like waviness or perhaps crowning issues that directly impact noise. Every aspect of gear production needs to be examined to provide the most accurate results.
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.
