How to Calculate Planetary Gear Ratios: A Comprehensive Guide

Understanding Planetary Gear Ratios

Planetary gears or epicyclic gears are one of the most efficient gear systems in transferring torque and adjusting rotational speed. The ratios of these gears are calculated by the number of teeth each gear holds. The equation, (Number of teeth in sun gear + Number of teeth in ring gear) / Number of teeth in sun gear, will give you the gear ratio.

Our High-Quality Planetary Gears

We produce top-tier planetary gears with the following features:

  • High torque-to-weight ratio
  • Compact design and size
  • High power density
  • High efficiency
  • Smooth and quiet operation

Different Types of Planetary Gears and Their Features

Single-Stage Planetary Gear Set

These gear sets consist of a central sun gear, an outer ring gear, and several planet gears. They offer high power transmission in a compact size.

Multi-Stage Planetary Gear Set

Multi-stage gear sets contain more than one set of gears, providing higher gear ratios and torque output.

Selecting the Right Planetary Gear

When choosing a planetary gear, you should consider the following parameters:
