The performance of an Electric Vehicle Power Unit is directly connected with critical tolerances. Tolerances drive opportunities for performance enhancement with cost reduction. The tests normally used to determine and validate tolerances are both expensive and time consuming with prototype parts. By replacing the initial tests with Digital Twin simulations, results can be obtained quickly, and at a much lower cost. This article discusses one of these tests and the results. 

Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.

Electric vehicles could represent up to 70% of all cars by 2050. To ensure the acceptance of their vibrational and acoustical characteristics, profound NVH analysis is the key to minimize vehicle excitations caused by specific e-drive transmission designs.

Marposs has announced MAINDO, its new digital platform that integrates Marposs monitoring, measuring, testing or other manufacturer device/solutions throughout the entire production process, combining quality and process into a holistic production monitoring view.

Automation tasks are becoming ever more challenging. Using intelligent software in combination with the relevant automation solutions not only enables workpieces to be loaded and unloaded but also means that machine tools can be set up fully automatically through automatic replacement of tools and clamping devices. FRAI strives to be an innovative automation partner and is therefore developing highly flexible robot systems to respond to this trend. Concepts such as the mobileCELL are a complete first and enable a wide range of expansion stages, making them as future-proof and competitive as possible.

In this latest edition, issue 9, of the GEARS inline Customer Magazine, Klingelnberg once again presents all sorts of trends and innovations from the world of gears. This time, the machine manufacturer focuses primarily on the hot topic of noise behavior and analysis.

At AMB 2022, WFL Millturn Technologies will be presenting the new M20 MILLTURN complete machining center for the first time. Alongside gear skiving technology, there is clear trend toward automation and the integration of sensors. The latest solutions from WFL range from smart software to screw programming through to intelligent tools and clamping devices.

Forming tools are expensive, often made from carbide and tool steel. Carbide grinding is often the first choice today because customer requirements have increased and continue to increase in terms of complexity, dimensional accuracy and reproducibility. Apart from that, production must also be significantly more economical.

System-supplier Klingelnberg will be back at AMB (Booth C41, Hall 5), where it will be highlighting solutions for smooth-running gearboxes. The exhibit will feature the Höfler Cylindrical Gear Grinding Machine Speed Viper, the Klingelnberg Precision Measuring Center P 40 and the newly developed Höfler Cylindrical Gear Roll Testing Machine R 300.
