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

The essential design of a planetary gear unit includes a sun gear, a ring gear and several planetary gears. The planetary gears are backed by the ring equipment and rotate around sunlight gear. This operating theory provided the name to this type of gear unit. The apparatus unit’s drive and result 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 includes a positive influence on the internal forces in the gear unit. The load distribution over a number of planetary gears enables high torques to end up being transmitted in a compact design. The usage of helical gears decreases the running noises.
