compact random oscillation device

This gear mechanism, comprising just four gears, showcases self-contained oscillation in unpredictable directions and intensities. Ideal for micro machines, this miniaturizable design eliminates the need for ancillary electronic controls to randomize vibrations. Simply requiring a self-supporting free rotating gear set, it can be experienced physically via the demonstration stand. The middle gear moves across the ring gear's circumference, causing variable load-induced vibrations due to its wandering center of rotation, which results from dynamic centrifugal and frictional forces. This unpredictability avoids destructive resonance, prolonging your mechanical system's life. Removable for custom applications, the device can easily be mounted on a standard hex shaft.
