Description

Technical Field

[0001] The utility model relates to the technical field of planetary gears, in particular to an internal meshing planetary gear. Background Art

[0002] Planetary gears are gear systems that can rotate around their own axes like fixed-axis gears, but their axes can also rotate around the axes of other gears along with the planet carrier. Rotation around their own axes is called "rotation", and rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name.
