SPN planetary gear units excel due to their wide range of feasible applications. High rigidity combined with low radial backlash because of their dynamic positioning role. An extremely efficient, compact style for continuous procedure of your smart alternative. Or optimal soft running properties through floor helical gears. What do you consider to be essential when selecting a gear unit? You select which requirements your gear unit should fulfil.
The essential design of a planetary gear unit consists of a sun gear, a ring gear and many planetary gears. The planetary gears are backed by the ring equipment and rotate around sunlight gear. This operating theory provided the name to this kind of gear unit. The gear unit’s drive and result functions can be performed by the sun gear, the housing or the planetary carrier, depending on the design.
In the most typical design, the epicyclic gear unit, the drive planetary gearbox function is conducted by the 
sun gear, the output function by the planetary carrier, and the housing is stationary. This design has a positive influence on the inner forces in the gear unit. The load distribution over several planetary gears allows high torques to be transmitted in a compact design. The utilization of helical gears reduces the running noises.
