Internal spur gears are specialised gearing designed to achieve specific motion conversion and functional integration. They serve not only as transmission components but also, in certain applications, as structural supports or motion trajectory controllers.
Beyond conventional rotational motion transmission, internal spur gears can achieve substantial speed reduction ratios within specific mechanisms, such as planetary gear trains with a small number of teeth. Their operating principle relies on the difference in tooth count between the planetary gear and the internal ring gear, enabling a significant reduction ratio through a minute tooth difference.
Primarily employed to achieve specialised motion functions and exceptionally high gear ratios:
