Planetary Gearboxes

request-a-quote

Planetary Gearbox have three major components :

  • Sun gear : The sun gear is meshed around with the planet gears, which in turn are meshed with ring gear.
  • Planet gear : Planet gears are connected to each other by a carrier, which helps them to rotate around the sun gear.
  • Ring gear :

The sun gear is meshed around with the planet gears, which in turn are meshed with ring gear. Planet gears are connected to each other by a carrier, which helps them to rotate around the sun gear.

Advantages of Planetary gear box system over helical gearbox :

  • Planetary Gearboxes are compact, light weight and take less space, because load is shared between the planet gears.
  • Vibration and noise is reduced because load is shared. its also increases efficiency, Since the shafts are inline and concentric, bending moment is absent.
  • Favorable volume output
  • Manufacturing of these components is relatively cheaper due to smaller size as compared to parallel axis Planetary Gearbox.

Disadvantages of Planetary Gearbox:

  • Gear system is very complex & needs precision manufacturing.
  • Teeth ratios are specific and assembly is according to them.
  • Calculations of efficiency are a bit difficult.
