Description
Technical field
The invention belongs to large ship low speed heavy-duty bearing technical field, and in particular to a kind of mixing channel water lubrication rubber peculiar to vessel
Glue bearing.
Background technology
With the progressively popularization that sliding bearing is applied, the important species that water lubricated rubber bearing develops as it, changes
It is all to be formed the secondary traditional thought of friction with metal structure to have become in conventional machine driven system, not only save substantial oil and
Precious metal material, and bearing shafting structure is enormously simplify, avoid seriously polluting the situation of water environment because greasy dirt leaks.
Water lubricated rubber bearing fluting is single at present, be generally all used at a high speed, underloading and the smaller bearing of draw ratio.
Water lubricated rubber bearing is with its pollution-free, material saving, low cost；The series of advantages such as wear-resistant, resistance to silt, corrosion-resistant and in ship
Oceangoing ship, water pump industry obtain extensive use, become one of underwater optimum bearing.It is for solving to use metal in current aqueous medium
Sliding bearing frequently occurs seal failure, bearing bush abrasion problem, expensive for simplifying mechanical lubrication and sealing system structure and saving
Heavy non-ferrous metal bush material, all has great importance.All the time, go back neither one and reasonably design program and design rule
Model instructs the design of water lubricated rubber bearing.Whether general water lubricated rubber bearing structure design considers draw ratio, slots, rubber
A lot of aspects such as bondline thickness, lath shape, joint face shape, fluting type.So its structure design need further
It is perfect.
For rubbing surface shape, it is flat that Duan Fangli thinks that the frictional behaviour in underloading or speed operation concave is significantly better than
Face type, and change of the frictional behaviour of concave bearing to speed and load is more sensitive.Wear the experiment and simulation study in bright city
Show, plane is better than concave or convex-surface type, is that it is more likely formed bullet-modeling hydrldynamic pressure lubrication, has and preferably starts
Property and low-speed running performance.Therefore from the critical speed and the angle of friction factor for reducing the generation of tail tube bearing singing sound, recommend to make
Use plane.R.L.Daugherty etc. thinks that rubber layer thickness is smaller, and friction coefficient is smaller, thus from reduce water lubrication tailing axle
Hold the angle of the critical speed operating mode of singing sound generation, it is recommended to use plane thin rubber-strip.Hardness is smaller, and rubber surface rubs
It is lower to wipe coefficient, selects the rubber lath of suitable stiffness also critically important.Recall in week etc. by emulation and Experimental comparison, result of study table
Bright, sink radius size, rubbing surface shape and the secondary friction coefficient that rubs of water lubricating rubber alloy bearing are to water lubrication rubber
The frictional noise of glue alloy bearing has considerable influence, and influence of the shape of sink to bearing friction noise is little.Zhou Huanhuan etc.
Impact effect of the hardness subregion to contact performance under the different lath types of three kinds of comparative analysis, the results showed that, hardness subregion energy
The contact performance of bearing is significantly improved, the Static Contact performance of concave lath pattern is preferable.To sum up, concave bearing capacity compared with
It is good, hence it is evident that better than plane and convex-surface type, plane has preferable water guide effect, easily forms elastohydrodynamic lubrication moisture film, convex-surface type
Be conducive to the circumferential circulation of water, but larger friction and wear can be caused, suitable for the big rubber lining of soft, thickness.
For sink type, in order to lubricate, cooling down, discharge silt, water lubricating rubber tail tube bearing working surface is generally all
Sink is provided with, and it is the most general with U and V-type axial groove.Lubricities of the Liu Yu et al. for axially grooved water lubrication tail tube bearing
It can carry out numerical computations and analysis, the results showed that：The distribution of bearing circumferential pressure is discontinuous after fluting, and pressure is reduced at sink
0, the bearing capacity of bearing reduces；And the width of groove is bigger, number is more, and the bearing capacity of bearing is also just smaller.Moreover,
U-type groove is conducive to fluid flowing, and dovetail groove has preferable bearer properties, forms continuous moisture film, is not easily broken.These are all bases
In the research of basic sink, do not account for different trough-like shapes and contrast optimization is not carried out to different sink structures.
All it is single research sink rubbing surface shape or sink type above, does not consider the coupling after both combine
Group photo is rung.
For common trench digging groove bearing, due to the difference of its groove species, have not to bearing capacity, fluid flowing etc.
Same influence, but the distribution of bearing circumferential pressure and moisture film flowing change are not all considered.Single point is carried out for single bearing
Single design is analysed, does not account for result after its mixing.
Selection for direction of slotting, helicla flute can guide seawater to carry out screw along groove, and then generate
Certain spiral centripetal force, easily forms elastic hydrodynamic lubrication, and current mobility in groove caused by helicla flute
More steady, the impact influence on unit of axle of ship propellor is smaller, but under low-speed heave-load effect, due to the too big meeting again of helical angle
Generation resistant function is flowed to it；Longitudinal groove, since water supply is sufficient, its lubricant effect is good, cools down uniformly reliable, mud
Sand is easily gone out outside stern bearing, and frictional work damage is smaller, and processing and manufacturing is relatively easy.But current mobility in its caused groove
Larger, unstable, easily producing larger impact to unit of axle of ship propellor influences.General water lubricated rubber bearing is all provided with longitudinal ditch
Groove or spiral groove, but all there are each side advantage and deficiency.It need further to grind for the refinement of guiding gutter
Study carefully.
For common trench digging groove bearing, due to the difference of its groove species, have not to bearing capacity, fluid flowing etc.
Same influence, but the distribution of bearing circumferential pressure and moisture film flowing change are not all considered.Single point is carried out for single bearing
Single design is analysed, does not account for result after its mixing.
In bearing machining and installation process, technique and all follow-up to the water lubricated rubber bearing work of method and failure
There is vital influence.General water lubricated rubber bearing is more by the way of the fixation of strip type bearing bolt, long-term
Work under alternate stress, the changing of the relative positions easily occur, cause naval vessel afterbody to produce extraordinary noise and shafting safety problem.And during installation
It is also required to consider the eccentricity of bearing, such as without considering the unbalance response of bearing rotor system may be caused.So installation process
And method could be improved.

Flowing velocity is optimal, but combines circumferential flow and contrast, and larger, fluid stability is fluctuated in (II) number water lubricated rubber bearing distribution
Difference；Fluid maximum fluidity speed in (III) number water lubricated rubber bearing is relatively low, but circumferential flow stability is preferable.To sum up,
Maximum fluidity speed of the fluid in (IV) number water lubricated rubber bearing is only second to (II) number, and has the good circumferential flow steady
Qualitative, the advantages of combining these three bearings, (IV) number water lubricated rubber bearing result on fluid flow characteristics is preferable.
To sum up analyze, selection present invention mixing slot structure, which has water lubricated rubber bearing elastohydrodynamic lubrication effect, significantly to be changed
Into.
