Disclosed is a planetary gear transmission box, comprising a housing portion, a first planetary gear transmission stage, and a second planetary gear transmission stage, wherein the first planetary gear transmission stage comprises a first sun gear (3), a first planetary carrier (5), and a first ring gear; the second planetary gear transmission stage comprises a second sun gear, a second planetary carrier (7), and a second ring gear (6); the first sun gear (3) is connected to an external input element; the first planetary carrier (5) is connected to the second sun gear; the second planetary carrier (7) is connected to an output element; the transmission ratio of the gear transmission box is greater than 25; and the second planetary carrier (7) is directly supported on the housing portion. The locked rotor torque of the gear box is increased, such that the output rotational speed is reduced, and thus a bearing member at the output end can be omitted.
