Planetary gearboxes have much higher mechanical rating compared to parallel shaft gearboxes as the power being transmitted gets equally distributed among four streams in each stage thus reducing the induced stresses, which very much optimizes the sizes as well allows 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
tone of 50% reduction in floor space.
• Heaviest gear internals such as annuli are stationary thus requires no bearing and automatically
improves the stability and reduces the vibration level and in turn noise. Low noise level 80-85 db as
well as low vibration level going up to 4.5 mm/sec can be achieved.
• Planetary gearbox has an advantage the planet bearings are only loaded where as in case of bearing supporting sun or carrier loads are more or less nullified by virtue of higher number of planets and their equal and opposite forces.
• Lubrication of planetary gearbox is quiet simple as the rotating gear train partially acts as pump thus
allowing splash lubrication.
• We are proposing two to four stage planetary gearboxes; in each stage sun is input and carrier is the output keeping annuli stationary as well acting as casing.
• Elecon Benzler’s machine capability cuts the internal teeth of annulus to the accuracy of DIN-7 or Grinds if required to the accuracy class DIN-6.
