Compound planetary gearset
WebThe project focused on the Ravigneaux planetary gearset, the Base mechanism for the 6-speed Automatic transmission. The goal of the project was to find the optimal design for this planetary gearset where the design has to be optimized in term of the efficiency and size, but subjected to gear ratios, tooth strength, scuffing, and geometry constrains. WebThe power transmission system shown in Figure Q1 consists of a compound planetary gearset with one common annulus A. The planet gears P1 mesh with the internal teeth of A and the sun gear S1. The planet gears P1 are free to spin on axles that are mounted on the planet carrier C1, which is integral with the second sun gear S2.
