Description
Technical Field
The utility model relates to the technical field of lubricating oil sealing of engine bearings, in particular to a novel-structure carbon ring sealing device.
Background
A carbon ring seal is a component for rotary shaft sealing, commonly used in pumps, compressors, rotary machinery, etc. in industrial equipment. It consists of two parts, a carbocycle and a metal shell. The carbocycle is made of carbon materials through high-temperature compression, and has excellent wear resistance, corrosion resistance and high-temperature resistance. Carbocycles are generally shaped like a flat ring for contact with the rotating shaft and seal formation. The carbocyclic surfaces are typically coated with a special lubricant to reduce friction and wear.
Among the prior art, as chinese patent CN215861741U discloses a carbocycle sealing device, including carbocycle sealing sleeve, carbocycle sealing sleeve includes sealing sleeve first, sealing sleeve first's one end opening is connected with flange first, sealing sleeve first's the other end opening is connected with flange second, be equipped with wear-resisting bush in the sealing sleeve first, sealing sleeve first and wear-resisting bush are equipped with carbocycle seal cover first between, carbocycle seal cover first includes seal cover body first, be equipped with a plurality of sealed outer eaves ring first along circumference extension along the axial interval on the outside of seal cover body first, form location sealing connection in the sealing ring groove on the inboard corresponding position of sealing sleeve first is stretched into to sealed outer eaves ring first.
However, in the prior art, the traditional comb teeth seal ring is sealed, so that the engine bearing lubricating oil sealing effect is poor, and lubricating oil leakage is easy to occur, so that the sealing device is inconvenient to use.
Disclosure of Invention
The utility model aims to solve the problems that the sealing effect of lubricating oil of an engine bearing is poor, and the lubricating oil is easy to leak, so that the sealing device is inconvenient to use in the prior art due to the fact that the sealing of a traditional comb tooth sealing ring exists.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a carbocycle is sealed device of novel structure, includes the carbocycle mount pad, the carbocycle has been placed to the upper end of carbocycle mount pad, carbocycle end cover has been cup jointed to one side of carbocycle mount pad, O type circle has been cup jointed to the opposite side of carbocycle mount pad.
Preferably, the upper end of the carbon ring is provided with a wave spring, and the upper end of the wave spring is fixedly connected with a wave spring pressing pad.
Compared with the prior art, the utility model has the advantages and positive effects that:
1. according to the utility model, through the arrangement of the carbocycle mounting seat and the carbocycle end cover, the carbocycle is positioned by the carbocycle mounting seat and the carbocycle end cover, and the carbocycle inner ring and the cylindrical end surface of the rotating shaft are separated by the fluid film, so that sealing is realized, and therefore, poor lubricating oil sealing effect of the engine bearing is prevented, and lubricating oil leakage is prevented.

FIG. 1 is a schematic cross-sectional view of a novel carbon ring seal device;
legend description: 1. a carbocycle mount; 2. an O-ring; 3. a carbocycle; 4. a wave spring; 5. a wave spring pressing pad; 6. a carbocyclic end cap.
Detailed Description
In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.
Embodiment 1, as shown in fig. 1, the utility model provides a novel-structure carbocycle sealing device, which comprises a carbocycle mounting seat 1, wherein a carbocycle 3 is arranged at the upper end of the carbocycle mounting seat 1, one side of the carbocycle mounting seat 1 is sleeved with a carbocycle end cover 6, and the other side of the carbocycle mounting seat 1 is sleeved with an O-shaped ring 2.
The concrete setting and effect of this embodiment are specifically said below, through the setting of carbocycle mount pad 1 and carbocycle end cover 6, carbocycle 3 is fixed a position by carbocycle mount pad 1 and carbocycle end cover 6, separates by the fluid film between carbocycle inner circle and the rotation axis cylinder terminal surface, realizes the seal to it is not good to have prevented engine bearing lubricating oil seal effect, appear the lubricating oil leakage.
In embodiment 2, as shown in fig. 1, a wave spring 4 is disposed at the upper end of the carbon ring 3, and a wave spring pressing pad 5 is fixedly connected to the upper end of the wave spring 4.
The whole embodiment achieves the effect that when the dynamic pressure floating force is larger than the combined acting force of the gravity force of the sealing ring, the inertia force of the floating motion and the contact friction force of the sealing ring and the end face of the shell, the wave spring 4 descends, and therefore the space between the carbon ring inner ring and the cylindrical end face of the rotating shaft is separated by the fluid film.
The application method and the working principle of the device are as follows: the carbocycle 3 is fixed a position by carbocycle mount pad 1 and carbocycle end cover 6, and when dynamic pressure buoyancy lift force is greater than the combined effort of the gravity of sealing ring, the inertial force of floating motion and sealing ring and casing terminal surface contact frictional force, wave spring 4 descends, then separates by the fluid film between sealing ring and the rotatory cylinder surface to avoid the contact friction of metal casing, separate by the fluid film between carbocycle inner circle and the rotatory shaft cylinder terminal surface, realize the seal.
The present utility model is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present utility model without departing from the technical content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
