Theoretical and experimental modelling of the tribological behaviour aspects of contact elements in the precessional gearing (PG). In: Journal of Engineering Sciences, 2022, vol. 29, nr. 2, pp. 8-17. ISSN 2587-3474. DOI: 10.52326/jes.utm.2022.29(2).01 | Project: | 20.80009.700.24 Increasing the competitiveness of precessional transmissions by developing and capitalizing on the gear with conform contact of the teeth and expanding their application area | Journal: | Journal of Engineering Science | Abstract: | This paper deals with the theoretical-experimental model of the tribological behavior of the contact elements in precessional gears (PG) in the functions of conjugate profiles of linear velocities “convex-concave” or “convex-convex” for the corresponding geometric parameters (ρki, r, ρki – r) and the values of the kinematic force parameters (VE1, VE2, Vai) for each concrete position of the ki points. The calculation of the constructive-functional and kinematic parameters of the “roller-shoe” and “roller-roller” elements of the tribocouple were adjusted for the experimental verification tests on the SMT-1 installation and adapted to the specific test conditions of the tribocouples with conformal contact of gear teeth made of plastics, which will be subjected to sliding friction and rolling processes of the concrete tribocouple elements. |
