Preferably, the top of the box body is fixedly provided with an upper cover plate, and one side of the box body is embedded with a ventilation cap.

Preferably, the input shaft, the transition shaft, the output shaft and the box body are rotatably connected through deep groove ball bearings, bearing covers are mounted on the outer sides of the joints, and lip-shaped sealing rings are arranged at the joints of the bearing covers and the deep groove ball bearings.

Preferably, the input shaft, the transition shaft and the output shaft are parallel to each other.

Preferably, the first chain wheel and the second chain wheel are respectively and fixedly connected with the input shaft and the output shaft through flat-end set screws.

Preferably, the first gear and the input shaft, the second gear and the third gear and the transition shaft, and the fourth gear and the output shaft are all fixedly connected through flat keys.

For the sake of simple explanation, the speed reduction box of the shredder is simply referred to as the speed reduction box.

The reduction gearbox has the advantages that: this reducing gear box simple structure is compact, operate steadily, two kinds of rotational speeds of exportable, the outside of axle and box junction all is provided with bearing cap and lip seal, made a closed gear box with whole reduction gears, by the initiative axle through two sets of gear reduction, conduct and divide the pole to take turns to epaxially, make the inside sealed condition that keeps that can be fine of box, it air-dries too early to avoid the lubricating oil between the gear, reduce life, be provided with the inside and outside atmospheric pressure of the cap of ventilating of being convenient for simultaneously, the aperture of the cap department of ventilating of accessible adds lubricating oil. This configuration facilitates maintenance, lubrication and replacement.
