The gearbox of decanter centrifuge is a major component of the rotating assembly, which creates the differential speed between the bowl and the conveyor.
The planetary gearbox system consists of a pinion shaft and gear, which engages three planetary gears (mounted on carrier plates) which in turn engage a ring gear fixed to the gearbox casing. For the decanter centrifuge the epicyclic gearbox involves two stages. although recently three stages have been in use. The carrier plate of the first stage holds a second pinion shaft carrying the sun gear for the second stage. The ratio of the gearbox is the product of the ratios for each stage. The maximum practical ratio for any stage is just over 1 3. giving a maximum ratio for a two-stage planetary gearbox of 170 to 180. Three stage epicyclic gearboxes with ratios over 500 have been used on decanters.
