Double Epicyclic Gear Apparatus | ProDynami – 1288
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.
The Double Epicyclic Gear Apparatus ProDynami – 1288 consists of two standard epicyclic gear trains for laboratory demonstration of gear systems similar to those used in automotive applications. This Double Epicyclic Gear Apparatus lets users calculate and experimentally observe angular velocity ratios, torque ratios, and efficiencies of gear trains. It supports a wide range of gear ratios and output directions through different gear train combinations.
Product Overview
This apparatus consists of two standard epicyclic gear trains for laboratory demonstration of gear systems similar to ones used in automotive applications.
Each gear train consists of 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. The planet gears are mounted on shafts that turn in the planet carrier and mesh with both the sun gear and the ring gear. Pulleys fitted with protractors are attached to the input and output shaft so that torque and velocity ratios may be determined. Torques can be applied to the shaft by adding weights on cords wrapped on the pulleys. Bearings are used in the entire unit to minimize friction losses.
The Double Epicyclic Gear Apparatus can be operated in a variety of modes. Locking pins are used to hold different parts of the apparatus in position. This gives the user different options on gear ratios that can be applied between the input and output shafts. By changing the combinations between the first and second epicyclic gear sets, a wide range of ratios and different output directions can be produced.
Efficiencies can be calculated for the unit’s operation, as well as theory tables given for the different gear combinations. A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results, is provided. All necessary assembly and operational tools are provided.

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.
