SPN planetary gear products excel due to their wide range of feasible applications. High rigidity coupled with low radial backlash for his or her dynamic positioning role. A highly efficient, compact style for continuous operation of your smart answer. Or optimal soft running properties through surface helical gears. What do you consider to be important when selecting a gear device? You select which requirements your gear unit should fulfil.
The essential design of a planetary gear unit 
contains a sun gear, a ring gear and many planetary gears. The planetary gears are supported by the ring gear and rotate around sunlight gear. This operating theory offered the name to this type of gear unit. The apparatus unit’s drive and result functions can be carried out by sunlight gear, the casing or the planetary planetary gearbox carrier, based 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 inner forces in the gear unit. The strain distribution over several planetary gears allows high torques to be transmitted in a concise design. The usage of helical gears reduces the running noises.
