Planetary gear

Planetary gear

Overview:

  • Diameter 42, 52, 62, 81mm
  • Torques up to 120Nm
  • Reductions up to 1: 308 depending on the number of stages
  • Number of steps up to 4
  • Available with special flange and special reductions.

Characteristics:

  • The planetary gear are higher loadable than spur gear with comparable size.
  • Long service life at input speeds up to 4500 / min.
  • High efficiency.
  • Grease lubrication for life maintenance free.

Planetary gears work as they are called: in the middle is the sun gear, which is driven by the engine. It transmits its movement to three revolving planet wheels that form a step. They are arranged on the bearing pin of a planet carrier. Each of the last planetary carrier is firmly connected to the output shaft and thus ensures the power transmission at the output. Outside, the planet gears run in a gear housing with internal teeth, the so-called ring gear.
