SPN planetary gear devices excel because of their wide range of feasible applications. High rigidity combined with low radial backlash for his or her dynamic positioning role. An extremely efficient, compact style for continuous procedure of your smart option. Or optimal soft running properties through ground helical gears. What perform you consider to be important when choosing a gear device? You select which planetary gearbox requirements your equipment unit should fulfil.
The essential design of a planetary gear unit contains a sun gear, a ring gear and several planetary gears. The planetary gears are backed by the ring equipment and rotate around the sun gear. This operating theory provided the name to this type of gear unit. The gear unit’s drive and result functions 
can be performed by sunlight gear, the housing 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 includes a positive impact on the inner 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.
