The planetary gear set 7 includes a ring gear 6 fixed in the planetary gear housing 4 and a bracket 14 fixed on a shaft sleeve 18. A sun gear 17 is fixed on the shaft sleeve 18. One side of the bracket 14 is movably connected to a plurality of planetary gears 12 through a planetary gear shaft 16. The planetary gears 12 are meshed with the sun gear 17. One side of the planetary gear 12 is meshed with the ring gear 6. A connecting rod 15 is provided on one side of the bracket 14. An oil seal 5 is placed in the planetary gear housing 4. The two sides of the oil seal 5 are respectively against the ring gear 6 and the planetary gear housing 4. A plurality of heat sinks 9 are equidistantly provided on the side of the planetary gear housing 4. The connecting shaft 13 is driven to rotate by the motor 1, and the sun gear 17 is driven to rotate by the connecting shaft 13. The sun gear 17 drives the planetary gears 12 to rotate. Since the planetary gears 12 are meshed with the ring gear 6, the purpose of driving the planetary gear housing 4 to rotate is achieved, and the synchronous wheel 3 is driven to rotate by the planetary gear housing 4.
