|Coordinator||Swerim AB - Swerim AB, Kista|
|Funding from Vinnova||SEK 3 000 000|
|Project duration||December 2018 - November 2021|
|Venture||The strategic innovation programme for Metallic material|
Purpose and goal
The aim of the project is: - Groundwork for implementing high performance steels into gear components within the powertrain of mainly trucks and cars. - The possibility to evaluate if and when, both in a production technology and economically perspective, high performance steels and power skiving should be implemented. - Through these new technologies, produce high strength complex components for future vehicles. A longer component life length will also result in a lower life cycle CO2-emission. - To find optimized machining processes adapted to high performance steels.
Expected results and effects
The project will result in: - Possibility to implement high performance steels in future competitive powertrain components, with benefits in light-weight due to smaller components as well as increased fatigue performance. - New process knowledge (power skiving) for more flexible and productive gear manufacturing. - The machinability limitations and recommendations for high performance steels in both conventional gear production and power skiving. - A demonstrator produced from high performance steel and power skiving.
Planned approach and implementation
The work will be done according to specified work packages: 1- Selection of gear geometry and state-of-the-art 2- Cutting tool development 3- Machining of high performance steels 4- Future gear production: Power skiving 5- Demonstrator and education package
