A typical planetary gear train has three components: the ring gear, the Sun gear, and the planet carrier connecting the two together. The input shaft ends in a plate called planetary carrier. This leads to different gear ratios and output rotation directions. At the second stage, the planet carrier acts as the input for the second planetary gear set, the larger sun gear (which is held stationary) acts as the sun, and the ring gear acts as the output, so the gear ratio is: 1 / (1 + S/R) = 1 / (1 + 36/72) = 0. Recommending an alternative product in an existing application is an easy task, as our engineers know that their design is safe. Looking for Planetary Gear Assembly? Find it at Grainger.
