Double Epicyclic Gear Apparatus | ProDynami - 1288
Product Overview
The Double Epicyclic Gear Apparatus ProDynami - 1288 demonstrates gear systems using two epicyclic gear trains similar to automotive applications. This Double Epicyclic Gear Apparatus supports Planetary, Star, and Solar configurations, with 48 tooth Sun, 16 tooth Planet, and 80 tooth annulus gears. Torque is applied via weighted pulleys, with 360° protractors measuring input and output angles. Multiple weight sets and a comprehensive instruction manual are included.

Construction and Design
The Double Epicyclic Gear Apparatus ProDynami - 1288 consists of two epicyclic gear trains, each with a sun gear in the centre, three planet gears, a planet linkage, and an internal or ring gear. The sun gear, ring gear, and planet carrier all rotate about the same axis. Planet gears are mounted on shafts that turn in the planet carrier and mesh with both the sun gear and the ring gear. The gear tooth counts are 48 tooth Sun, 16 tooth Planet, and 80 tooth annulus. Pulleys fitted with protractors, marked to 360°, are attached to the input and output shafts. Locking pins hold different parts of the apparatus in position, enabling single or two stage gear train operation, with each capable of being locked off for 1:1 ratio, or Planetary or Star configurations. Bearings are used throughout the unit to minimize friction losses. Input and output shafts can be reversed.
