A planetary gearbox, also known as epicyclic gear train, is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form.
Planetary gearbox units are modular and consists of different types of end stages, gear ratio’s and various input flanges and shafts, also the input shaft and the output shaft are aligned. The input side of the planetary gearbox units are suitable for IEC motors, couplings and hydraulic motors. The output side also has several options: hollow shafts with shrink disc mounting, cylindrical shafts with keyway or spline. Optionally spline welded bushings or flanges are also possible.
It is possible to make many different combinations, because of the modular construction of the planetary stages. This allows it to almost always create the desired transmission.
