Embodiment Construction
[0012] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0013] As shown in the drawings, the low-noise planetary gear speed-increasing box of the wind generator according to the present invention includes an input shaft 1, a box body 2, an inner ring gear 3, a planetary gear shaft 4, a central shaft 6, and a planet carrier 17. The planet carrier 17 has a barrel-shaped structure, and the outer wall of the planet carrier 17 is provided with hollow holes to facilitate gear meshing. The input shaft 1 and the planet carrier 17 are coaxial and fixedly connected together. More than two planetary gear shafts 4 are evenly distributed and installed in parallel on the planetary carrier through the bearing support. Three planetary gear shafts 4 can be evenly distributed around the axis of the planetary carrier 17 or more. A small planetary gear 7 and a large planetary gear 8 are fixedly installed on the planetary gear shaft 4...
