Obiettivo NTN-SNR is a major supplier for the helicopter gearbox bearings and more generally for the European market. NTN-SNR has developed a related knowhow in calculation, design, manufacturing to assist all its customers. This explains NTN-SNR’s strong will to answer to this topic.The NTN-SNR objectives for this project are to develop, design, manufacture, test and simulate the new generation of tapered bearings for aerospace applications and especially for the helicopter gearbox bearings. For NTN-SNR, hybrid bearing is a promising solution for aerospace market especially thanks to the weight saving and the potential improvement of the bearing life duration it offers. The objective of NTN-SNR proposal is to meet the topic leader requirements. To do so, the hybrid bearing prototypes will be designed, calculated, manufactured, and tested to compare steel and hybrid bearing behaviour and to demonstrate the benefits.For test activity, the objective is to perform the back-to-back assessment under several test conditions (clean environment, contaminated conditions, poor lubrication conditions, oil shut off conditions and tests with defect on rollers) in order to demonstrate the benefits offered by hybrid tapered roller bearings.In order to start aerospace mass production of hybrid tapered roller bearings, the critical defects (size, shape, location on the rolling element) have to be defined. Hence one of NTN-SNR’s objective is to determine the size of critical defect on tapered roller bearing performance. This activity will be based on NTN-SNR knowledge on hybrid bearings with the complement of dedicated tests that will be performed in the scope of this project.The last objective is to simulate the hybrid bearing behaviour in order to update NTN-SNR’s handbook and design rules to guarantee the quality, the robustness and the optimization of our bearing designs.The means implemented to meet these objectives are described in the part B (§3) Campo scientifico ingegneria e tecnologiaingegneria meccanicaingegnerizzazione dei prodottiingegneria e tecnologiaingegneria meccanicatribologialubrificazionescienze naturaliinformatica e scienze dell'informazionesoftwarescienze naturalimatematicamatematica puraanalisi matematicaanalisi funzionaleingegneria e tecnologiaingegneria meccanicaingegneria dei veicoliingegneria aerospazialeaeromobiliaerogiro Programma(i) H2020-EU.3.4. - SOCIETAL CHALLENGES - Smart, Green And Integrated Transport Main Programme H2020-EU.3.4.5.3. - IADP Fast Rotorcraft Argomento(i) JTI-CS2-2017-CFP06-FRC-02-24 - Hybrid bearings technologies Invito a presentare proposte H2020-CS2-CFP06-2017-01 Vedi altri progetti per questo bando Meccanismo di finanziamento CS2-IA - Innovation action Coordinatore NTN-SNR ROULEMENTS SA Contribution nette de l'UE € 597 935,63 Indirizzo Rue des usines 1 annecy 74000 Annecy Francia Mostra sulla mappa Regione Auvergne-Rhône-Alpes Rhône-Alpes Haute-Savoie Tipo di attività Private for-profit entities (excluding Higher or Secondary Education Establishments) Collegamenti Contatta l’organizzazione Opens in new window Sito web Opens in new window Partecipazione a programmi di R&I dell'UE Opens in new window Rete di collaborazione HORIZON Opens in new window Altri finanziamenti € 256 258,12
