planetary gear unit

SPN planetary gear models excel because of their wide range of possible applications. High rigidity combined with low radial backlash for his or her dynamic positioning role. A highly efficient, compact style for continuous procedure of your smart solution. Or optimal soft running properties through ground helical gears. What do you take into account to be important when choosing a gear unit? You select which requirements your equipment unit should fulfil.

The basic design of a planetary gear unit includes 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 offered the name to this type of gear unit. The apparatus unit’s drive and output functions can be performed by the sun gear, the casing or the planetary carrier, based on the design.

In the most planetary gearbox 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 has a positive influence on the inner forces in the apparatus unit. The strain distribution over many planetary gears allows high torques to become transmitted in a compact design. The utilization of helical gears reduces the running noises.
