planetary gear unit

SPN planetary gear devices excel due to their wide range of feasible applications. High rigidity coupled with low radial backlash for their dynamic positioning role. A highly efficient, compact design for continuous procedure of your smart solution. Or optimal simple running properties through ground helical gears. What perform you consider to be important when choosing a gear device? You select which requirements your gear unit should 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 planetary gearbox sunlight gear. This operating basic principle 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 housing or the planetary carrier, based on the design.

In the most common 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 internal forces in the gear unit. The load distribution over a number of planetary gears allows high torques to be transmitted in a compact design. The usage of helical gears decreases the running noises.
