Fundamental design of planetary gear units
The basic design of a planetary gear unit includes a sun gear, a ring gear and many planetary gears. The planetary gears are supported by the ring equipment and rotate around the sun gear. This operating basic principle gave the name to this kind of gear unit. The gear unit’s drive and output functions can be performed by the sun gear, the housing or the planetary carrier, based on the design.

In the most common design, the epicyclic gear unit, the drive function is performed by the sun gear, the output function by the planetary carrier, and the housing is stationary. This design has a positive impact on the internal forces in the apparatus unit. The strain distribution over a number of planetary gears enables high torques to end up being transmitted in a concise design. The utilization of helical gears decreases the running noises.
