Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , a sealing device for ship shaft parts. The sealing device is composed of a Y-shaped cup 7, an emergency sealing device, a housing 9, an inner end cover 10 and an outer end cover 11. The Y-shaped cup 7 The inner diameter is equal to the outer diameter of the transmission shaft 12, the outer diameter of the Y-shaped cup 7 is equal to the inner diameter of the housing 9, and one side of the groove of the Y-shaped cup 7 faces the outer end cover 11 outside the hull. A cup pressure ring 8 is fixed between the Y-shaped cup 7 and the outer end cover 11. One end of the cup press ring 8 is pressed in the groove of the Y-shaped cup 7, and the other end is connected with the outer end cover 11. ;

The invention relates to a sealing device for a ship shaft part, wherein the sealing device is composed of a Y-shaped cup, an emergency sealing device, a shell, an inner end cover and an outer end cover; the emergency sealing device is composed of a gear rod, a gear ring, a pushing ring, an O-shaped ring and a thrust ring; one part of the gear rod is arranged in a cabin and the other part is arranged in the shell; the gear rod is engraved with a gear A on the outer circumferential surface of the inner part of the shell; the outer circumferential surface of the gear ring is engraved with a gearB; the gear rod and the gear ring are in meshed connection with each other through the gear A and the gear B; internal screws are arranged in the inner hole of the gear ring; the pushing ring is boss-shaped; external screws are arranged in the inner hole of the corresponding gear ring on the outer circumferential surface at one side of the boss; the plane side of the pushing ring is connected tothe thrust ring by the O-shaped ring; and the other side of the thrust ring is connected to the plane side of the Y-shaped cup. The sealing device provided by the invention has simple operation, convenient control, simple production and better sealing effect.
Description
technical field [0001] The invention relates to the technical field of ship sealing, in particular to a sealing device for ship shaft parts. Background technique [0002] The place where the ship is more likely to leak water underwater is the drive shaft. The deeper the underwater position, the greater the pressure, the greater the pressure difference inside and outside the ship, and the greater the possibility of leakage, which directly affects the safe operation of the ship. The performance of the sealing device puts forward higher requirements. In order to solve the sealing of the connecting part between the drive shaft and the hull and prevent the water outside the ship from leaking into the ship, the traditional ship sealing method mainly adopts the radial sealing device. When the conventional sealing structure will fail, an emergency sealing device is needed to ensure Water cannot get into the cabin and there is time for damaged parts to be replaced.
