Planetary Gear Box

About Planetary Gear Box

Product Description
Planetary Gearboxes are compact, high-torque gear reduction units designed for heavy-duty industrial applications. The gearbox consists of a central sun gear, multiple planet gears, and an outer ring gear, which together provide high torque transmission in a compact design. Due to their load sharing capability among multiple gears, planetary gearboxes offer excellent efficiency, durability, and high power density.

Gear Type Used

Sun Gear (Central Gear) Drives the planet gears from the center.
Planet Gears (Multiple Gears) Rotate around the sun gear and share the load equally.
Internal Ring Gear Outer gear with internal teeth that supports the planet gears.
