Planetary Gearbox

A planetary gearbox—also known as an epicyclic gear train—is a compact, high-efficiency transmission system widely used in industries requiring high torque density, reliability, and precise motion control. It comprises a central sun gear, multiple planet gears, a ring gear, and often a planet carrier. This design ensures excellent torque distribution and minimizes backlash, offering superior performance compared to traditional gear systems..

Planetary gearboxes achieve torque conversion by distributing load across multiple gears. This simultaneous engagement allows the system to deliver high torque in compact dimensions, making it ideal for space-constrained applications. The load sharing among planet gears ensures uniform wear and extended lifespan.

LeanMotor specializes in high-efficiency planetary gearbox manufacturing for NEMA 17 to NEMA 42 sizes. We offer extensive OEM ODM customized capabilities, featuring adjustable reduction ratios (3:1 to 512:1), low-backlash designs, and specialized shaft machining. With 15+ years of expertise and ISO/CE certifications, LeanMotor delivers robust gear solutions for robotics, CNC machinery, and medical automation worldwide.
