UGRacing is the University of Glasgow’s Formula Student team. Since its inception in 2005, the team has been working to compete at Formula Student UK (FSUK). Over the last decade, the team has grown to over 150 members across ten disciplines. With a strong focus on knowledge transfer and iterative design, the team has worked year after year to develop new technologies and a more refined package. In 2022, the team saw a culmination of all their hard work when they placed first overall in FSUK with their final internal combustion vehicle. The following switch to an electric powertrain brought new challenges. Through the constraint of a new powertrain architecture, the team has explored and innovated drivetrain concepts which, in future years, will improve vehicle performance.
Mechanical design engineers planning a drivetrain typically have a range of component options to choose from, and many decisions will boil down to the specific application. When it comes to creating optimal torque output, rotational speed and direction, few decisions are as important in designing high performing gear drives as choosing the right gear for the job.
The Timken Company has agreed to acquire CGI Inc., a Nevada-based manufacturer of precision drive systems serving a broad range of automation markets with a concentration in medical robotics. The deal is subject to customary closing conditions, including regulatory approval, and is expected to close in the third quarter.
Gear drives are fundamental in most processing operations, connecting the prime mover to the driven equipment and ensuring that the system has enough torque to effectively move product. Correctly specifying and selecting the proper gear drives for critical applications leads to reliability, greater uptime and profitability.
Verification of a drive system should include all main elements of the system, which are gears, bearings, shafts, and depending on the application other parts such as screws, couplings, and connections. Gears are clearly the most complicated parts for verification, but in many cases, a gearbox failure has its origin in a shaft or bearing failure. The subject of this paper is to explain how verification of a drive system based on measured or simulated torque-speed-time data can be handled.

Sports fans want to see every little detail, and the TV cameras deliver whether the goalie is clenching his jaw before the spot kick or how many millimeters the serve cleared the net in a tennis match, everything is captured in detail. Images like these are only possible when the camera is up-close and doesn’t interfere with the action. Many major tournaments and Olympic Games use miniature devices, which even fit in a corner flag, from the Wiesbaden-based specialist LMP Lux Media Plan. Drive units from Faulhaber are used to adjust the shutter and focus.
Salim Haffar, deputy general manager at I-MAK, was reelected as president of EUROTRANS in 2022. This is Haffar’s third term in this role. PTE recently caught up with Haffar to discuss the evolution of EUROTRANS, the focus of the International Drive Conference at Hannover Messe and the current state of I-MAK’s gearbox business in Turkey.
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.
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.

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.
