planetary gear unit

SPN planetary gear models excel due to their wide range of feasible applications. High rigidity coupled with low radial backlash because of their dynamic positioning role. A highly efficient, compact design for continuous operation of your smart option. Or optimal soft running properties through ground helical gears. What do you take into account to be important when choosing a gear unit? You decide which requirements your equipment unit should planetary gearbox fulfil.

The basic design of a planetary gear unit consists of a sun gear, a ring gear and several planetary gears. The planetary gears are supported by the ring equipment and rotate around sunlight gear. This operating basic principle offered the name to this kind of gear unit. The apparatus unit’s drive and result functions can be performed by the sun gear, the casing or the planetary carrier, depending on the design.

In the most typical design, the epicyclic gear unit, the drive function is conducted by the sun gear, the output function by the planetary carrier, and the housing is stationary. This design includes a positive impact on the internal forces in the apparatus unit. The strain distribution over several planetary gears enables high torques to end up being transmitted in a compact design. The usage of helical gears decreases the running noises.
