Planetary gearbox for sugar mills

Model: Planetary gear reducer for sugar cane mills

•      Planetary gearbox have much higher mechanical rating compared to parallel shaft gearbox and more compact as the power being transmitted gets equally distributed among three to five streams in each stage ,thus reducing the induced stresses which very much optimized the size as well as follows to accommodate higher ratio to eliminate open pair.The reduction in floor space as compared to conventional drive i.e with open gearing,almost to the tune of 50% reduction in floor space.

      Heaviest gear internal such as annuli are stationay thus requires no bearing and automatically improves the stability and reduces the vibration level and in turn noise.Low noise level of 80-85dB as well as low vibration level going up to 4.5mm/s can be achieved direct drive eliminating open gears,bearings for same,coupling in between secondary gearbox and open gearing ,thus saving 5%-6% power consumption.For example,for a 45x90 mill for power 1100kw which also includes the drive power of TRPO/GRPF we can get a saving which is approximately equivalent to 20% of the additional expenditure for drive-part.i.e.within five seasons additional expenditure is recovered and sugar starts earning additional profit due to this solution
  

     Planetary gearbox have an advantage that the planet bearing are only loaded where as in case of bearing supporting sun or carrier loads are more or less nullified by virtue of higher no of planets and their equual and opposite forces.
  

     Lubrication of planetary gearbox is quite simple as the rotation gear train partially acts as pump thus allowing splash lubration

    We are proposing three to five stage planetary gearbox in each stage sun is input and carrier is the output keeping annuli stationary as well acting as casing and supported saddle as shown in drawing.
