Abstract
A planetary gear transmission mechanism includes an input shaft, an input bevel gear connecting to the input shaft, four planetary bevel gears meshed with the input bevel gear, an output gear driven by the planetary bevel gears, a stationary bevel gear meshed with the planetary bevel gears, and four bearing modules. The output gear evenly defines four through holes along one axis. Each planetary bevel gear is received in one through hole and rotatably connected to the output gear. The rotation axis of each planetary bevel gear is substantially perpendicular to the rotation axis of the output gear. The stationary bevel gear meshes with the planetary bevel gears. The input bevel gear and the stationary bevel gear are positioned on opposite sides of the output gear respectively. The bearing modules are received in the through holes respectively, and each bearing module rotatably supports one planetary bevel gear.
