Internal Planetary Gears: Precision and Power by FMP

Internal planetary gears, a vital component of planetary gear mechanisms, are renowned for their ability to deliver high torque and precise speed reduction in compact designs. These systems feature a central sun gear, orbiting planet gears, and an internal ring gear that meshes internally with the planet gears. This unique configuration makes internal planetary gears essential for industries across Italy, from the automotive workshops of Milan to the machinery hubs of Bologna. At FMP, we specialize in crafting these advanced gear systems, offering tailored solutions to meet the diverse needs of our clients.

What Are Internal Planetary Gears?

An internal planetary gear system consists of:

Sun Gear: The central gear that drives the mechanism.
Planet Gears: Gears that orbit the sun gear, connected by a carrier.
Internal Gear (Ring Gear): A gear with teeth on its inner surface, meshing with the planet gears.

Unlike external gear systems, the internal gear design allows for higher reduction ratios in a smaller footprint, making it ideal for applications that require power and space efficiency. By fixing different components (such as the internal gear or the carrier), the system can achieve different reduction ratios, providing flexibility to engineers everywhere.
