Document Type and Number:
WIPO Patent Application WO/2019/200898
Kind Code:
A1
Abstract:
The present invention discloses an improved planetary gear reducer, comprising: a center gear; a stationary gear circumferentially disposed around one end of the center gear; at least one planet gear mechanism disposed between the stationary gear and the center gear; and an output gear disposed on and around the circumference of the other end of the center gear. The planet gear mechanism comprises: a planet carrier rotatably disposed on the stationary gear; a planet shaft disposed on the planet carrier; and a planet gear rotatably disposed on the planet shaft. The stationary gear, the output gear, and the center gear are coaxially arranged. The axis of the planet gear is parallel to the axis of the center gear. The planet gear meshes with the center gear, the stationary gear, and the output gear. The stationary gear and the output gear have different numbers of teeth. The improved planetary gear reducer provided by the present invention has a simple structure, low cost, and high precision.
