Planetary Gearboxes

  • These gearboxes are available in free input type, hollow input type (suitable for standard B5 flange electric motor), with flange and foot mounting. 
  • The planetary gearboxes consist of input shaft assembly, sun gear, planet carrier assembly (consists of planets, planet pins and rollers), ring gear, output shaft, casing (foot/flange). 
  • The input comes from sun gear and drives motion through the coaxial planet carrier assembly and ring gear. The rolling contact of the planets with the stationary ring gear provides the reduction ratio. 
  • Hence, high transmission is possible in small size and result is less weight and less cost.
