Abstract
The utility model relates to a combined type seal ring for a ship, which belongs to a seal ring for the ship. The combined type seal ring comprises a skeleton and a rubber seal body, wherein the skeleton is of the groove shape; the rubber seal body is arranged in the groove of the skeleton; a radial seal lip is arranged on the outer circumference surface of the rubber seal body; the radial seal lip is in interference fit with the adjacent inner side surface of the groove of the skeleton; an end surface seal lip is arranged on the upper end surface of the rubber seal body; the end surface seal lip clings to the upper end surface of the skeleton; and the lip opening is of the filleted corner. The combined type seal ring has simple structure, is easy to assemble and has better seawater corrosion resistance as well as good water-sealing and sand-sealing effects.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of seal ring peculiar to vessel.
Background technique
At present, we common sandy beach shipowner will be used to plunge into the commercial sea and carry out the towboat operation, bearing seal positions such as its motor, wheel portion often contact with seawater and silt, seawater causes erosion to bearing easily, and a large amount of infiltrations of silt also can make bearing break down, more than two kinds of situations all cause the sandy beach ship normally not use.In order to guarantee the proper functioning of bearing, must seal reliably it, avoid it being damaged because seawater and silt enter in the bearing.
The model utility content
The purpose of this utility model is to have proposed a kind of built-up boat seal ring, and it has resistance to corrosion seawater and the husky effect of reliable sealing clay preferably.
The utility model is to adopt following technological scheme to realize: a kind of built-up boat seal ring, comprise skeleton and rubbery sealed body, wherein, the shape of skeleton is groove shaped, and rubber seal is arranged in the groove of skeleton, and the outer peripheral surface of rubbery sealed body is provided with the radial seal lip, be interference fit between the inner side surface of radial seal lip and adjacent skeleton groove, the upper-end surface of rubbery sealed body is provided with the end face seal lip, and the end face seal lockjaw is affixed on the upper-end surface of skeleton, and its lip is a fillet.
In the utility model, described rubbery sealed body outer peripheral surface is provided with at least one radial seal lip.
The lower end surface of described rubbery sealed body is provided with positioning boss.
Described skeleton is made by stainless steel.
The beneficial effects of the utility model are: this built-up boat is simple with ring structure, is convenient to assembling, and has resistance to corrosion seawater preferably, and water shutoff and sealing clay sand are effective.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
As shown in Figure 1, the sealing circle is made up of rubbery sealed body 1 and skeleton 3, and the shape of skeleton 3 is groove shaped, rubber seal 1 is arranged in the groove of skeleton 3, and be interference fit between rubbery sealed body 1 and the skeleton 3, for fear of getting rusty, skeleton 3 can adopt stainless steel to make.The outer peripheral surface of rubbery sealed body 1 is provided with radially double-sealing lip 4, radially is interference fit between the inner side surface of double-sealing lip 4 and adjacent skeleton groove, thereby has improved the reliability of water shutoff and sealing clay sand.The upper-end surface of rubbery sealed body 1 is provided with end face seal lip 2, and end face seal lip 2 is close to the upper-end surface of skeleton 3, has played the effect of sealing seawater and sandy soil, and its lip is a fillet, has reduced the rotational resistance after rubbery sealed body 1 compresses with skeleton 3.
During installation, apply power in the upper-end surface of rubbery sealed body 1, rubbery sealed body 1 is pressed in the groove of skeleton 3, and makes end face seal lip 2 be close to the upper-end surface of skeleton 3 as the figure direction.For the ease of the location of rubbery sealed body 1, the lower end surface of rubbery sealed body 1 is provided with positioning boss 5.
In addition, the radial seal lip can adopt radially double-sealing lip, also can be radially single sealing lip, also can be three or more sealing lips.The sealing circle is mainly used in the sandy beach ship, and the husky effect of its water shutoff, sealing clay is better, easily assembling.
