planetary gear unit

SPN planetary gear units excel due to their wide range of feasible applications. High rigidity combined with low radial backlash for their dynamic positioning role. A highly efficient, compact style for continuous operation of your smart alternative. Or optimal clean running properties through surface helical gears. What perform you take into account to be important when selecting a gear unit? You select which requirements your equipment unit should fulfil.

The basic design of a planetary gear unit planetary gearbox consists of a sun gear, a ring gear and several planetary gears. The planetary gears are backed by the ring gear and rotate around the sun gear. This operating basic principle gave the name to this type of gear unit. The apparatus unit’s drive and output functions can be carried out by sunlight gear, the casing 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 includes a positive influence 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 compact design. The use of helical gears decreases the running noises.
