AM Planetary Carrier Product Overview
This is the Carrier Plate w/ Sun Gear (AM Planetary Carrier) for the AM Planetary gearbox. Five planet gears (not included) ride on the dowel pins pressed into this part. Referencing the picture above, those dowel pins protrude out the carrier plate’s bottom side.

Introduction to Planetary Gearsets
Most commonly-encountered gear trains are relatively simple, having only one input and one output, and thus only one overall ratio. The planetary gearset is much more versatile since it has two inputs and one output. As we will see, this versatility comes at a price: planetary gearsets are much more complicated to design and analyze than ordinary gearsets. They often behave in counterintuitive ways, making their use all the more difficult (but enjoyable!) As with standard gearsets, however, a few simple rules can be used to determine the performance and efficiency of any planetary gearset.
The most common type of planetary gearset like in the figure above. It consists of four major components: the sun, one or more planets, a ring gear, and a carrier (often called the arm or the spider). The significant difference between planetary and ordinary gearsets is that the planets ‘orbit’ the sun; their shafts are not stable in space. It is this epicyclic motion that permits such exciting behavior.
