Compact and lightweight – such is the most common requirement for the gearboxes of emission-free, electric drives. With seven basic gearboxes, the LPI series by Liebherr fulfils exactly this need for high power density. With their low weight, reduced installation space and torque ranges from 20,000 Nm to 350,000 Nm, they are ideally suited as drives for crawler and crawler undercarriages. Customized large gearboxes are even available up to the maximum torque of 2,300,000 Nm.
For this paper, the digital twin refers to a digital asset that exists alongside the physical asset during its operational life, providing insight into and feedback on the physical asset’s performance and health. Thus, the focus is on the DTI, with the potential to aggregate data into a DTA for the gearbox design being considered, and within the DTE set up by Hexagon.
In respect of the physical asset across its life, nothing is more important about its performance than its ability to function, i.e., reliability, and for CAE, nothing is of greater importance than to be able to predict the reliability of a product being designed. Thus, for this study, whilst gearbox noise, efficiency, and thermal behavior may be of interest, the primary interest is fatigue and reliability.
Half a million global visitors visit Aiguille du Midi as an access point for skiing in the winter and hiking, rock climbing and paragliding in the spring, summer, and autumn seasons. The mountain—part of the French Alps—boasts the current title of employing “the world’s highest vertical ascent cable car.” This unique transportation takes passengers from 3,396 to 12,605 ft. above the clouds. The planetary gearboxes needed for the cable car operation are provided by CMD Gears.
With the release of version 9, the FVA-Workbench once again sets new standards in gearbox design, enabling the seamless integration of the latest research results into industrial practice. As a groundbreaking interface between collective research and application, the FVA-Workbench accelerates development and innovation in drive technology. This new release is more powerful than ever, with innovative features for flexible load spectra and improvements in FEM components and shaft-hub connections.
Drive specialist Flender has received the Supplier Excellence Recognition Award 2023 from U.S. machinery manufacturer Caterpillar. Flender received the award for maintaining 95 percent delivery

Atlanta Gear Works (AGW) is expanding its support staff by hiring its first Human Resources Specialist, a new position created to meet its expanding HR needs, previously managed by the company’s chief financial officer.
Sumitomo Drive Technologies is expanding its range of precision gear products and upgrading its ECY series with higher torque and a plug & play drive for motor connection. The ECY series comprises high-precision shaft gears, used for example for surface machining in dental technology or in collaborative robots (cobots). Thanks to their internal cylindrical roller bearings, the gear units provide both high rigidity and higher performance in a smaller design envelope.
This report derives the equation for relative elastohydrodynamic lubrication (EHL) film thickness. Mineral (MIN), polyalphaolefin (PAO), and polyalkylene glycol (PAG) lubricants with viscosity grades of ISO 320, 150, and 32 are analyzed.
Portescap introduces the new R22T gearhead, the latest addition to its existing 22 mm gearbox portfolio. As a mid-torque gearhead, the R22T fills the gap between our light-torque R22 and high-torque R22HT gearheads. It is also fully compatible with Portescap’s brush DC and brushless DC slotless motors.
