Abstract


An extensive study was made on the tribological behavior of the contact of the precessional transmission (PT) gear. The research was carried out on tribomodels at an SMT-1 type installation according to a methodology previously developed by the authors. The concave-convex contact of teeths of the PT was simulated in the non-conformist research by contact between two cylindrical rollers with different diameters. The cylindrical rollers were made from the materials taken in the study. In the framework of the experimental research, based on a study carried out by the authors, were used metallic and plastic materials, recommended for the design and manufacture of gear wheels. Obtained research results, allowed the choice of the materials for the gear wheels manufacturing for PT and the lubrication type from the point of view of the tribological behavior of the contact (according to the anti-friction criterion).
