Abstract
A sealing device of a pulp raking machine is characterized in that two ends of a cutter shaft of the pulp raking machine are respectively provided with two sealing devices, namely a floating oil seal device is arranged between a fixed shaft and a bearing seat of the pulp raking machine, the floating oil seal device comprises two floating rings and two O-shaped rings, the O-shaped rings are sleeved on the peripheries of the floating rings, and the end surfaces of the two floating rings are in close contact with sealing lubricating oil; a cutter shaft is connected between the fixed shaft of the first sealing device and the fixed shaft of the second sealing device. The contact end surfaces of the two floating rings are smooth surfaces. The two floating rings are made of high-strength alloy. The floating oil seal device is positioned between the fixed shaft and the bearing seat, the cutter shaft rotates, the fixed bearing seat contacts lubricating oil through the end face of the floating ring, and the two oppositely arranged floating rings rotate relatively. Two floating rings that set up relatively are in close contact with, and sealed effectual, because the material of two floating rings is high strength alloy, so wear-resisting, long service life.
