SPN planetary gear models excel due to their wide range of possible applications. High rigidity coupled with low radial backlash for their dynamic planetary gearbox positioning role. A highly efficient, compact design for continuous operation of your smart alternative. Or optimal simple running properties through ground helical gears. What do you take into account to be important when selecting a gear device? You decide which requirements your gear unit should fulfil.

The essential design of a planetary gear A1unit contains a sun gear, a ring gear and many planetary gears. The planetary gears are supported by the ring equipment and rotate around sunlight gear. This operating basic principle gave the name to this kind of gear unit. The apparatus unit’s drive and output functions can be carried out by sunlight gear, the casing or the planetary carrier, depending on the design.

In the most typical 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 gear unit. The strain distribution over several planetary gears enables high torques to be transmitted in a compact design. The usage of helical gears decreases the running noises.
