[0027] See attached Figure 1-3A twenty-roller precision reversible cold rolling mill coiler gearbox and a large motor gearbox integrated machine, including a reducer body 8, the left and right sides of the reducer body 8 are respectively a small motor transmission assembly and a large motor transmission assembly; the small motor transmission assembly includes a small motor input shaft 1 rotatably connected to the reducer body 8, the outer end of the small motor input shaft 1 is connected to a small motor low-speed gear 11, one side of the small motor input shaft 1 is rotatably connected to a small motor intermediate shaft 2, the middle part of the outer side of the small motor intermediate shaft 2 is connected to a small motor shift gear 9, and the small motor shift gear 9 can be engaged and disengaged with the small motor low-speed gear 11 through the shift assembly. , one end of the outer side of the small motor intermediate shaft 2 is connected to the small motor transmission gear 2 18, and the small motor low-speed gear 11 can mesh with the small motor transmission gear 2 18. When the small motor shift gear 9 is separated from the small motor low-speed gear 11, the small motor assembly does not work. When the small motor shift gear 9 is meshed with the small motor low-speed gear 11, the small motor low-speed gear 11 is also meshed with the small motor transmission gear 2 18, so that the rotation of the small motor intermediate shaft 2 can be realized; the large motor transmission assembly includes a large motor input shaft 5 rotatably connected to the reducer body 8, and the outer end of the large motor input shaft 5 is connected to the large motor low-speed gear 12 One side of the large motor input shaft 5 is rotatably connected to the large motor intermediate shaft 4, and the middle part of the outer side of the large motor intermediate shaft 4 is connected to the large motor shift gear 10.
