GWJ Technology GmbH has presented a new version of its desktop solution TBK with numerous enhancements, particularly in the field of gearing. The TBK calculation software has been used successfully worldwide for more than four decades to dimension gears, shafts, connections, bearings, and other machine elements as well as complete gearboxes. With its various interfaces to 3D CAD systems, the TBK software is a powerful calculation tool for development, design, work planning, production, and quality assurance.

This week at Hannover Messe, Dana Incorporated is highlighting its broad range of next-generation motion systems offering superior performance, durability, and sustainability across the entire spectrum of industrial applications.
Located in Hall 6, Stand D48/1, Dana will feature its recently updated Brevini gearboxes and winches, as well as field-proven GWB industrial driveshafts.

As engineers, we all know how to quickly create a sketch of a gearbox or transmission using a few lines. Using maybe black for shafts, green for bearings, blue for gears and red to indicate the power flow. We do this to remember a great idea, communicate with customers or to pass time waiting at an airport. 

KISSsoft emulates this approach in a much more orderly fashion. Using only the mouse, complex schematics can be drawn and edited, thereby converting the structure of a gearbox into a logical and 3D model. The schematic in the Sketcher also serves as a navigation and visualization tool and is complemented by an overview of some of the key data (e.g. module and number of teeth) of the components making up the gearbox.

It's no secret that cycloidal gearboxes are important in mechanical engineering, especially when it comes to precision motion control and efficient power transmission. The gear systems differ from harmonic wave/strain wave gearboxes by using a cycloidal disk and needle bearings to transmit torque with minimum backlash, achieve high reduction ratios, and support substantial loads. This Sumitomo Drive Technologies blog will talk about single-stage and multi-stage cycloidal gearboxes.

Bonfiglioli recently inaugurated Bonfiglioli Academy at Chennai Institute of Technology, marking a new milestone in their journey of cutting-edge technological innovation. This collaboration with the institute is a powerful example of bringing academic expertise and industry leadership together. Bonfiglioli is confident that this partnership will redefine research and development and create an environment where theoretical knowledge meets practical application.

Spline rumble is characterized by a multiple low shaft order droning noise. It arises in electrified vehicle (EV) powertrains due to excitation at the spline connection between the motor rotor and the transmission input. It is caused by the interactions between manufacturing errors. In this article SMT will be looking at how MASTA can be used to predict rumble in a modern EV gearbox with a three-bearing input assembly layout.

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.
