In an urgent assignment, a gear has to be designed, with the engineer already knowing the required reduction ratio, torque and speed. On the manufacturing side, the preferred materials, possible qualities and the reference profiles are specified. This initial situation represents an everyday task.

NYCU (National Yang Ming Chia Tung University) Vulpes Racing—founded in 2008—is a Formula Student Team that combines mechanical engineering, industrial design, public relations, video production and marketing expertise. 

More than a billion people around the world unite to ring in the New Year, their eyes set upon the glittering New Year’s Ball in Manhattan. Thousands are gathered at Times Square — the famed “Bow Tie” of Midtown — braving the December cold and peering through glasses with numerically shaped frames. Millions more tune in from their various screens at home.
With so much riding on its descent, the Ball, along with the mechanical and electrical systems responsible for its operation, must operate like clockwork.

This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.

For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.

Today, gearboxes are inevitable in numerous applications requiring high power density including wind turbines, electric vehicles, cranes, robotics, etc. A combination of high-ratio gearboxes with high-speed, low-torque motors is often used to achieve high power density. Planetary gear trains (PGTs) help achieve a high gear ratio in a compact arrangement. Several configurations of planetary gears are widely studied in this article where the gear profiles used in these studies are primarily involute.

Harmonic Drive announces the release of its HPF series of hollow shaft gear units. Designed for heavy-duty industrial applications, these advanced gear units offer high torque outputs and flexible installation options, making them ideal for use in demanding environments.

Gear Motions is proud to announce that Auto Gear Inc. has joined the Gear Motion’s family. Auto Gear located in Syracuse, New York, specializes in efficient and economical low-volume gearbox production, from design to delivery. 

Interact Analysis have recently released the 3rd edition of the Geared Motors and Industrial (Heavy-Duty) Gears report. This market study covers finished geared motors and gearboxes for general industrial use, including light- and heavy-duty products, as well as planetary gears, with the exclusion of precision gearboxes and loose gear parts. In this edition, amidst global macroeconomic uncertainty, market trend projections have become more volatile compared to previous years.

For optimal gear design in accordance with requirements, it is essential to consider load spectra under the most realistic conditions possible as early as the virtual basic design phase. This is the only way to ensure that all components are loaded as evenly as possible to avoid overdimensioning.

Optimized design saves resources and costs and improves the CO₂ balance – an aspect that is becoming increasingly important in the current environment and can offer a competitive advantage. Load spectrum calculations are also important for replacing complex time and cost-intensive experiments by simulating test rig damage tests.
