Inline & MultiDrive Planetary Gearheads
Planetary Gearboxes are constructed with a sun gear, ring gear and planetary gears. The sun gear is the central gear which is fixed in the center, ring gear (annulus ring) which is the outer ring with inward-facing teeth, and the planetary gears which rotate around the sun gears and mesh with both the sun and ring gear. Planetary gearboxes are used in applications requiring low backlash, compact size, high efficiency, resistance to shock, and a high torque to weight ratio.
Advantages of Planetary Gears include:
- High power density
- Compact design
- High efficiency
- High permissible input speed
Disadvantages of Planetary Gears include:
