SPN planetary gear units excel because of their wide range of possible applications. High rigidity coupled with low radial backlash because of their dynamic positioning role. An extremely efficient, compact style for continuous operation of your smart option. Or planetary gearbox optimal easy running properties through surface helical gears. What perform you take into account to be essential when choosing 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 equipment and rotate around the sun gear. This operating theory provided the name to this type of gear unit. The apparatus unit’s drive and output functions can be carried out by the sun gear, the casing or the planetary carrier, based on the design.
In the most typical design, the epicyclic gear unit, the drive function is conducted by sunlight 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 load distribution over a number of planetary gears allows high torques to end up being transmitted in a compact design. The use of helical gears reduces the running noises.
