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 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.
.
This study aims to propose a robust reverse engineering methodology for straight bevel gears, especially for those found in inter-wheel differentials.
.
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.

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.

When grinding steel parts, the surface of the part can "burn" if too much heat is applied in a short time. Grinding burn refers to all those structural changes in edge zones of steel parts that are caused by grinding processes in steels due to the thermal energy introduced. Grinding burn can mainly occur in the form of tempering zones or new hardening zones.

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.
