Difficult general conditions, rapidly rising food and fuel prices, as well as the ongoing coronavirus pandemic and related regional lockdowns weighed on economic development and slowed economic growth in the past business year. Nevertheless, Liebherr’s total revenue increased significantly compared to the previous year. The group achieved increased revenue in 10 of its 13 product segments, some of them significant. It thus surpassed its previous record from 2021 by €950 million.

At Interpack in Dusseldorf, the drive specialist Nord Drivesystems will present its wide product portfolio and great expertise in the packaging industry from May 4-10, 2023 – from decentralized frequency inverters to energy-efficient drives to high-performance surface treatments for washdown or spray areas.

Bonfiglioli S.p.A, global leader in the market of drives for industrial automation, wind generators and mobile machinery in the construction, earthmoving and intralogistics sectors, following the communication released on February 7, 2023, is proud to announce that it completed the 100% acquisition of the share capital of Selcom Group. 

Sumitomo Drive Technologies and Lafert Group will be jointly exhibiting a new version of their drive for applications in automated guided vehicle (AGV) systems at Logimat 2023 from April 25 to 27 in Stuttgart, Germany (Booth F45, Hall 6). The Smartris Drive Compact is a compact drive that is just a quarter of the size of the standard model.

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.

The following article is a collection of products and technologies featured at IFPE and CONExpo/CONAGG 2023. 

At this year’s Hannover Messe, NKE Austria GmbH will present bearings for wind turbine gearboxes and generators. The Austrian bearing manufacturer has more than 20 years of experience in the wind energy sector. NKE bearings have been installed in more than 4,000 wind turbines across Europe, the USA and China, equivalent to more than 10,000 MW of installed power. 

Sumitomo Drive Technologies, together with Invertek Drives and Lafert Group, will be presenting its complete drive solutions for automation and Industry 4.0 at Hannover Messe 2023. From April 17 to 21, visitors to Hall 6, Booth B25 will learn how they can use energy-efficient drive solutions to meet their sustainability goals while also boosting their competitiveness.

The International Fluid Power Exposition (IFPE), Las Vegas March 14-18, is where fluid power professionals meet to discover highly engineered solutions for improving mobile and industrial equipment's efficiency, performance, and sustainability. Attendees will also learn about the latest technology available to the industry and network to discuss and combat the most pressing industrial challenges.

Gears and gear racks used for transmitting torque and forces within gearboxes are typically made of hardened steel. For many other uses and applications, gears and racks made from plastic are the better choice. These generally require no lubrication and are lighter, quieter, less expensive, and more resistant to corrosion than metal gears. This is why JW Winco is expanding its range with polyamide gears and racks that can transmit high forces and torques.
