DETERMINATION OF OPTIMAL BACKLASH IN PLANETARY GEARBOXES
Mühendislik Bilimleri ve Tasarım DergisiPlanetary gear reducers are widely used in sectors due to their high efficiency. In this study, the design, analysis, and experimental validation of a planetary gear system with a module of 4 and a gear ratio of 3.56 consisting of a central sun gear, three planetary gears, and an internally toothed ring gear have been carried out. The sun and planetary

Modern methods of synthesis of automatic planetary gearboxes
Izvestiya MGTU MAMI, 2017 An increase in the number of gears in automotive transmissions is the most efficient way to reduce fuel consumption and improve the efficiency of automotive vehicles equipped with internal combustion engines. The more gears in the gearbox, the more complicated become the used mechanisms and their number increases as well.
