Technical Field

[0001] The utility model relates to the technical field of shaping devices, in particular to a cycloid pinwheel tooth profile shaping device. Background Art

[0002] A gear tooth is a raised portion on a gear that is used for meshing and can mesh with a raised portion on another wheel to transmit force and motion. Generally speaking, these raised portions are arranged radially and are used to contact similar raised portions on a mating gear, thereby allowing the gears to continuously mesh.
