Shinko Gear Co., Ltd. Internal Gear

An internal gear is a gear with teeth formed on the inside of a cylinder or cone.

An internal gear is a gear with teeth formed on the inside of a cylinder or cone. It is commonly used in planetary gear mechanisms. A regular gear is an external gear. The counterpart that meshes with an internal gear is always an external gear. Internal gears do not mesh with each other. Furthermore, the internal gear is always the larger gear, while the meshing external gear is always the smaller gear. The smaller gear is referred to as a pinion. For more details, please contact us.
