Planetary Gear Calculator

This planetary gear calculator makes it easy to analyze and visualize a wide range of epicyclic gear configurations. By selecting the fixed element - sun gear, ring gear or carrier - and defining the input and output shafts, the tool determines the resulting transmission ratio, output speed and direction of rotation. It accepts gear module, gear dimensions and either tooth counts or pitch diameters, automatically calculating any missing values required to complete the system. In addition to the numerical results, the calculator generates an SVG representation of the gear arrangement, providing an immediate visual overview of the planetary gear set. The resulting layout helps verify dimensions and better understand the relationship between the individual components.

Internal only: Non public drafts

The place where all articles go before getting published to be previewed, read and re-read again before being partially re-written. This is a queue and attic at the same time and only accessible by the author and some selected reviewers

Internal only: Project wiki

The internal place where I gather information about upcoming projects to keep track or a log about progress as well as share information with other participants on the projects. Usually everything will move to the public section when finished.
