A typical planetary gear train has three components: the ring gear, the Sun gear, and the planet carrier connecting the two together. February 2009 . Ring Speed. The layout of the gears mimics a model solar system, hence the name, including the sun gear in the center and planet gears (also called pinion gears) (shown in blue) around the sun gear (shown in orange). The carrier holds the planetary gears together and sets their spacing. The Ring gear has an additional construction circle drawn to guide the path of the Planet gears, this will be key to correct motion and will be called the Planet Gear Path. The dynamic parameters optimization of the compound planetary gear train is then conducted. Computational predictions and experimental results are shown to be in fairly good agreement. The planetary gears also mesh with the ring gear, which is stationary, causing the planetary gears to revolve around the sun gear. The following equation is used to calculate the output values of a gear reduction. Posted: 9/21/2019 1:39:12 PM EST planetary gear designer. The nut is the extended planetary carrier (red).
