This study investigates the influence of internal damping within drivetrain components.
NASA’s successful Artemis II mission represented the first crewed lunar mission since Apollo 17 in 1972 as well as a major leap forward in humanity’s return to deep space exploration. The mission launched on April 1, 2026, and lasted approximately nine days, one hour and 32 minutes.

Across sectors, the same operational truth is becoming harder to ignore: downtime has a direct impact on revenue. It ripples into supply chains, disrupts mission readiness, compromises service levels and, in some environments, creates genuine safety risk.
.
There’s a running theme throughout concrete and aggregate producers where the motors in crushers, conveyors and pumps need to operate efficiently, extend equipment life and cut downtime—easier said than done when dealing with dust, vibration and massive shock loads. These daily challenges can be the difference between having reliable onsite equipment or navigating the costs associated with unplanned failures.
.
Automation and smart technologies are fundamentally changing what manufacturing environments look like — and more importantly, what they can achieve. Rewriting the rules of flexibility and efficiency, automated and digitalized workflows make it possible to produce more complex products in less time with less waste.

For worm gearboxes, oils are mainly used in combination with splash lubrication. Consistent lubricants, such as greases, are used less frequently and are used, for example, in gearboxes where it is not possible or difficult to seal the housing (Ref. 1). These applications include positioning gears, but also power gears with high sealing requirements, such as in the food industry. Grease lubrication has, in comparison to oil, a negative thermal effect on the worm, resulting in higher mass temperatures (Ref. 2). However, this effect becomes less relevant in the application of positioning gears, so that the advantages of grease lubrication outweigh the disadvantages in these applications.
An innovative technology for the next generation of high-speed, high power density traction and propulsion systems has been jointly developed by Drive System Design (DSD) and Transense Technologies. David Hind, principal engineer, DSD, presented “Unlocking Powertrain Power Density with Innovative Motor Control,” earlier this year at the CTI USA Symposium 2025 in Novi, MI. The presentation built on initial simulation studies performed in MATLAB Simulink; a software tool used to design and simulate systems before moving to hardware. While simulation trials proved successful, achieving quality experimental results proved far more challenging. Hind examined these challenges and potential solutions at CTI.
Rolling bearings possess especially low friction characteristics. They make it possible to reduce bearing friction by half, offering the construction machinery sector the opportunity to achieve significant carbon dioxide savings without imposing high development costs. This article will examine the current solutions from Schaeffler.
Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable, but rather how to also get the desired performance.
