Description
Technical field
This utility model is related to a kind of water lubriucated bearing, more particularly to a kind of vibration and noise reducing water lubriucated bearing.
Background technology
The vibration noise problem of submarine navigation device water lubrication tail bearing is one of bottleneck problem of submarine navigation device, and it is serious
Affect the comfortableness of the disguise, reliability and occupant of submarine navigation device.Current most quiet submarine navigation device, even if using
Most sensitive underwater sound equipment also will could find it from it less than during 100m, often reduce radiated noise 6-10dB, the passive sound of enemy
The operating distance received can reduce about 50%, and the operating distance of one's own side's passive sonar can then improve 1 times or so, therefore to tail bearing
Vibration and noise reducing carries out studying the silence level and survival ability that can improve submarine navigation device.
Because the overhanging of propeller arranges that the working condition of tail bearing is extremely severe, and shafting vibration width in this place
Value is relatively large.First link element of base or even hull, decay of the tail bearing to vibrating are delivered to as shafting vibration
Ability has crucial effect.In addition, submarine navigation device is under the special operation conditions such as low speed, heavy duty, the higher ring of frequency is often produced
Sound, the sound absorbing capabilities for improving tail bearing have very important researching value.
In traditional water lubriucated bearing, panel surface is smooth, but the viscosity very little of water, low speed（<0.5m/s）, heavy duty with
And start, stop being hardly formed hydrldynamic pressure lubrication under operating mode, at this moment bearing is in boundary lubrication or mixed lubrication situation with axle,
Moisture film is difficult to set up, and bearing occurs and contacts with axle, produces viscous-sliding/friction vibration and noise.
Recent two decades come, and surface texture is considered as one of new method of raising Tribological Properties, in cylinder and work
The aspects such as plug ring, mechanical seal, bearing achieve certain progress, but are still blank in the application of water lubriucated bearing vibration and noise reducing.
In recent years, loose structure is considered as one of main method of raising material vibration and noise reducing, in high-speed railway compartment
The aspects such as material, high speed concrete road surface, antivibrator, foam metal material achieve certain progress, but subtract in water lubrication tail bearing
The application of noise reduction of shaking is still blank.
The content of the invention
The purpose of this utility model is to provide a kind of vibration and noise reducing water lubriucated bearing, can reduce vibration, reduces noise.
For achieving the above object, the technical solution adopted in the utility model is：Including bearing shell, metal inner ring, damping layer and
Bearing case.Bearing shell adopts rubber, or match dragon, flying dragon high-abrasive material, vulcanizes on the inner cylinder face of metal inner ring, axle on bearing shell
To lath and tank is alternatingly arranged with, surface texture pit is evenly distributed with panel surface, the inside of bearing shell is distributed with closing
Mesh, be damping layer between metal inner ring and bearing case, the inside of damping layer is distributed with the mesh of closing.
By such scheme, the cross section of described surface texture pit is circular or triangle or square.
By such scheme, described damping layer adopts rubber, or high polymer composite material.
By such scheme, packing material such as fiber is filled with mesh can strengthen the material of intensity.
This utility model can reduce vibration using said structure and material, reduce noise.

Fill material.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
As shown in figure 1, this utility model includes bearing case 1, damping layer 2, metal inner ring 3 and bearing shell 4.Bearing shell 4 is adopted
Rubber, or the high-abrasive materials such as dragon, flying dragon are matched, vulcanize on the inner cylinder face of metal inner ring, plate is axially alternatingly arranged with bearing shell
Bar and tank, in panel surface surface texture pit 5 is evenly distributed with, and the inside of bearing shell 4 is distributed with the mesh 6 of closing.Metal
It is damping layer between inner ring and bearing case, the inside of damping layer is distributed with the mesh of closing.
Water in tank plays a part of to cool down and lubricates.Surface texture pit 5 on lath remains with can rubbing surface
Lubricant medium, can re-lubrication surface, can also store abrasive particle, reduce friction and wear.Suitable surface texture shape, size,
Depth and distribution contribute to the improvement of sliding bearing frictional behaviour, and surface texture pit 5 causes the turbulence intensity of fluid to be aggravated, rapid
The energy of flow increases, and secondary vortices are formed in surface texture pit 5, and moisture film pressure increase, bearing load carrying capacity strengthens.Surface texture
The cross section of pit 5 can be circle, triangle, square or other figures, and the seamed edge of surface texture pit 5 is more, easier
Secondary vortices are formed, but easily occurs stress concentration at seamed edge, fatigue rupture is caused, so the cross section of surface texture pit 5
Shape should weigh the advantages and disadvantages according to material and actual requirement and be selected.This surface texture pit, can increase noise transmission
During reflection and refraction, consume noise energy, reduce the purpose of noise.
Damping layer 2 chooses rubber, or high polymer composite material.Damping layer 2 and bearing shell 4 are allowed to internal distribution through process
The mesh 6 of a certain size closing, loose structure increases the refraction and reflection during noise transmission, and plays slow to vibration
Punching is acted on.The mesh-structured intensity that can reduce damping layer 2 and bearing shell 4 during bearing heavy duty, needs are filled with packing material in mesh 6
7 such as fiber or other strengthen the material of intensity, so both reached the purpose of vibration and noise reducing, and do not reduce damping layer 2 and bearing shell 4
Intensity.
