[0018] like Figure 1 , 2 As shown in Figure 3, a saw blade spindle box assembly in this embodiment includes a spindle box 3 and a spindle body 14 extending through the spindle box 3. The two ends extending from the spindle body 14 are a transmission input end and a transmission output end, respectively. The spindle box 3 houses an input bearing and an output bearing mounted on the spindle body 14. The output bearing is a double-row tapered roller bearing 11, and the input bearing is a self-aligning roller bearing 15. The transmission output side of the spindle body 14 has an output shoulder, and the transmission input side of the spindle body 14 has an input shoulder. The outer end face of the output bearing abuts against the output shoulder, and the inner end face of the output bearing is provided with a spacer 12 and an output locking nut 13. The output locking nut 13 is threadedly connected to the spindle body 14, so that the output bearing is confined between the output shoulder and the output locking nut. A spindle end cover 9 is provided at the output end of the spindle box. The spindle end cover 9 is fixedly connected to the output end of the spindle box by screws. The inner end face of the input bearing abuts against the shoulder of the input shaft. The outer end face of the input bearing is sequentially provided with a bearing end cover 17 and an input locking nut 18. The bearing end cover is fixedly connected to the input end of the spindle box by screws. The input end of the spindle body 14 is provided with a shaft head 8, which is integrally formed with the spindle body 14. A saw blade 1 is fitted onto the shaft head 8, and the saw blade 1 is fixed to the shaft head by a locking device. The output end of the spindle body is provided with a synchronous pulley 6, which is fixed to the spindle body 14 by a tensioning sleeve 19. Another synchronous pulley is provided on the motor output shaft, and a synchronous belt is provided between the two synchronous pulleys. The motor drives the synchronous belt and synchronous pulley to rotate, causing the spindle body and the saw blade to rotate, thus enabling the saw blade to cut the plate.

[0019] An output labyrinth sleeve 10 is provided between the center hole of the spindle end cover and the spindle body. An input labyrinth sleeve 16 is provided between the center hole of the bearing end cover and the spindle body. The input locking nut is threadedly connected to the spindle body, so that the input locking nut abuts against the input labyrinth sleeve. The output labyrinth sleeve and the input labyrinth sleeve seal both ends of the main housing.

[0020] The locking component includes a locking disc 2, and the saw blade 1 is located between the locking disc 2 and the shaft head 9. The locking disc 2 is fixed to the shaft head 9 by fastening screws 7, so that the saw blade is fixed to the shaft head.

[0021] A gap exists between the inner cavity of the spindle box and the outer periphery of the spindle body, serving as a lubrication channel. The spindle box is equipped with an output bearing lubrication nozzle 21 and an input bearing lubrication nozzle 22. The output bearing lubrication nozzle 21 is located at the output bearing, and the input bearing lubrication nozzle is located at the input bearing.
