SPN planetary gear units excel due to their wide range 
of possible applications. High rigidity coupled with low radial backlash for his or her dynamic positioning role. An extremely efficient, compact planetary gearbox design for continuous procedure of your smart option. Or optimal even running properties through ground helical gears. What perform you take into account to be essential when selecting a gear device? You decide which requirements your gear unit should fulfil.
The essential design of a planetary gear unit includes 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 kind of gear unit. The apparatus unit’s drive and result functions can be performed by sunlight gear, the housing or the planetary carrier, depending on the design.
In the most common design, the epicyclic gear unit, the drive function is performed by sunlight 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 strain distribution over a number of planetary gears enables high torques to be transmitted in a concise design. The use of helical gears reduces the running noises.
