The new members of the Faulhaber metal planetary gearhead family are the 14GPT and 16GPT. The compact additions to the series deliver high torque with minimal volume, making them ideal for
demanding applications where space is limited. They are extremely robust, capable of withstanding frequent and sudden load changes, and operate with high efficiency. The gearheads can be
combined with a wide range of motors.
Study uses a Monte Carlo simulation to investigate the influence of tolerances on the load capacity.
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.
When it comes to twisting and bunching wire and cable, consistency is key. For example, the amount of insulation required for residential wiring depends on the wire’s lay — the distance between its twists, which is also known as the pitch. Without tight control during the wire bunching process, lay variations occur. As a result, the wire will require more insulation than necessary, raising its cost. A differential gearbox can drive rotating components in a single-twist buncher to provide a more uniform lay, using less power at a lower cost than a two-motor approach.
Andantex USA Inc. will be renamed Redex USA Inc., according to Thomas Osygus, vice president of sales and marketing, Redex USA. "Our name is changing, but we will continue to offer the same high-quality motion control systems you’ve come to expect from us for over 40 years."
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.
The earliest example of a gear train dates to at least 2,000 B.C. when Chinese engineers built a chariot that used a complex planetary mechanism made of wooden gears to let a dragon head continuously point south when driven around (Ref. 1). In Greece, a surprisingly advanced Antikythera gearbox mechanism, incorporating at least 37 precisely crafted bronze gears, was built years later, between 205–60 B.C. (Ref. 2).
I think I spend more time talking about ball bearings today than at any other time in my career. Ball bearings have always had a large place in automotive, but not typically in high demand positions—other than a few niche areas. High demand positions, such as axles and planetaries, were typically reserved for tapers, needles and cylindricals. The landscape is changing quickly.
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.
The goal of increasing the power density of a gear unit demands that extraneous material reserves can be detected and reduced to the necessary level. In this context, it is important to know the influences acting on the gear unit and the resulting loads. FVA examines the precise knowledge of the longitudinal load distribution in the gear meshes during operation, and specification of suitable microgeometries for its optimization, play a decisive role.
Bonfiglioli is convinced that around 50 percent of all new self-propelled construction machines will be either electrically or hybrid driven by 2030. So, it is high time for the globally active group based in Bologna, Italy, to take on the electric pioneering role in the machine groups that have previously been dominated by hydraulics. At Bauma 2022, the company presented the current options for electric drive technology for construction machinery.
Stöber Antriebstechnik GmbH + Co. KG rely on the FVA-Workbench for dimensioning and verification of their drives. The calculation and simulation software allows Stöber engineers to develop their innovative gear unit solutions more quickly and efficiently. The result: higher quality products.
Axially space-saving, economical, IP65-compliant and designed for high radial and axial forces at the output: The Neugart WPLHE combines all the advantages of the successful PLHE, as a right-angle variant.
Neugart refines its range of coaxial planetary gearboxes: Effective immediately, the manufacturer also offers a gear ratio i=8 for its precision gearboxes with helical gearing. Thus, the gear ratio range now extends from i=3 to i=100.
