In order to solve the technical problems, the sealed three-oil seal system for the gear box transmission shaft of the floor grinding machine comprises a gear box, wherein a main gear shaft is rotationally connected to the inside of the gear box, a coupling transmission gear is connected to the surface of the main gear shaft in a toothed manner, a linkage gear and a power gear are connected to the surface of the transmission gear in a toothed manner, a rotating gear is connected to the other end of the linkage gear relative to the transmission gear in a toothed manner, a gear long shaft is fixed in the rotating gear, a bearing is connected to the surface of the gear long shaft, an oil seal is arranged at the other end of the bearing relative to the rotating gear, an oil seal seat is connected to the other end of the oil seal seat relative to the bearing, a claw disc seat is arranged at one end of the gear long shaft, a threaded shaft is connected to the surface of the claw disc seat, a rubber pad is connected to the surface of the rubber pad through a bolt, and a three-star grinding disc is fixed on the surface of the rubber pad.
Preferably, a spring is arranged on the outer side of the threaded shaft, and two ends of the spring are respectively fixed on the surfaces of the gear long shaft and the three-star millstone.
Preferably, the surface of the gear box is provided with dust collection openings, and the dust collection openings are positioned at two four corners of the upper end of the gear box.
Preferably, the oil seals are three, and the oil seal seat is sleeved on the surface of one of the oil seals.
Preferably, the oil seal seat is connected with the gear box through bolts.
Compared with the related art, the three-oil seal system for the transmission shaft seal of the gear box of the floor grinding machine has the following beneficial effects:
According to the utility model, the number of the oil seals and the positions of the oil seals are increased, so that the occurrence of oil leakage can be effectively reduced, meanwhile, the oil seal seat can prevent external sediment from entering, the sediment is prevented from entering the middle of the oil seal and the gear long shaft, the service life of the oil seal is shortened, and the normal use of the floor grinding machine is ensured.
