Three Stage Epicyclic Gear | ProDynami – 1358
The Three Stage Epicyclic Gear, ProDynami 1358, is a wall mounted unit consisting of three coupled epicyclic gear sets for the study of planetary gear systems. It enables experiments on gear ratios, torque conversion, mechanical advantage, and efficiency across three forward speeds and one reverse speed. The Three Stage Epicyclic Gear features stainless steel shafts, aluminum gears and discs, and an anodized aluminum frame. It is supplied with weights, thread, and an instruction manual.
The Three Stage Epicyclic Gear ProDynami – 1358 consists of three coupled epicyclic gear sets, allowing students to carry out experiments on different gear ratios and torque conversions. This Three Stage Epicyclic Gear unit demonstrates the key functions of epicyclic gears, including coupling input and output shafts, torque generation, and rotation direction inversion. It is wall mounted with two graduated discs for checking velocity and torque ratios.
Product Overview
The most important elements of an automatic transmission are one or several planetary gears (or epicyclic gears), clutch packs, band brakes, and pilot valves. Epicyclic gears perform several functions: coupling between input and output shafts, generating high torque at the output shaft at low velocities, reducing torque at the output shaft at high velocities, and rotation direction inversion between the input and output shafts.
The Epicyclic Gear Unit (3 elements) consists of three coupled epicyclic gear sets. It allows students to carry out experiments of different gear ratios as well as torque conversions.
The epicyclic gears unit are the same and consist of the following elements: sun gears, satellite gears set, and ring. The unit has two graduated discs located at the input and output shafts, which allow checking of the velocity and torque ratios according to the application of the different brakes. The power arrives to the epicyclic gears through the sun gears on this Three Stage Epicyclic Gear unit.

Construction and Design
The Three Stage Epicyclic Gear, ProDynami 1358, is built as a wall mounted unit consisting of three coupled epicyclic gear sets. Each set is formed by sun gears, a satellite gears set, a common support of the satellites, and an external ring. Two graduated discs are located at the input and output shafts. Different mechanical pins simulate the pilot valves used to brake the different planetary components. The shafts of the unit are made of stainless steel. The discs and gears are made of aluminum to facilitate the experiments. The frame is anodized aluminum, and the panels are made of painted steel. The pinions are made of aluminum and are mounted on ball bearings to reduce losses due to friction, making the practical exercises easy to perform. The unit provides three forward speeds and one reverse speed.
