[0025] Such as Figure 1 to 6 As shown, a reduction gearbox for turbine fracturing, the reduction gearbox includes a sun gear shaft 2, a planetary gear 11 and a bearing 13, the planetary gear 11 is three, the bearing 13 is six, the bearing 13 is two by two. The set is used to fix a planetary gear 11, 6 bearings 13 and 3 planetary gears 11 are respectively sleeved to form 3 sets of planetary gears. The sun gear shaft 2 includes a big end gear and a small end gear. The big end gear is distributed around the center of the circle, and the planetary gear 11 meshes with the big end gear. The three planetary gear sets are evenly distributed around them with the big end gear as the center. The gearbox has a large transmission ratio, and the power is input from the small end gear of the sun gear shaft, and the large end gear of the sun gear shaft meshes with the planet gear 11 to reduce speed and increase torque, and output through the planet carrier 9. The use of the structure of the...
