Description
Technical field
The invention belongs to large ship low speed heavy-duty bearing technical field, be specifically related to a kind of mixing channel water lubrication rubber peculiar to vessel
Glue bearing.
Background technology
Along with the progressively popularization of sliding bearing application, the important kind that water lubricated rubber bearing develops as it, change
Become in conventional machine driven system the traditional thought being all to be constituted friction pair with metal structure, not only save substantial oil and
Precious metal material, and enormously simplify bearing shafting structure, it is to avoid the situation of serious pollution of water environment because of greasy dirt leakage.
Water lubricated rubber bearing fluting is single at present, is the most all used for the bearing that high speed, underloading and draw ratio are smaller.
Water lubricated rubber bearing is pollution-free with it, material saving, low cost；Silt wear-resistant, resistance to, the series of advantages such as corrosion-resistant and at ship
Oceangoing ship, water pump industry obtain extensively application, become one of the most optimum bearing.It is for solving to use in current aqueous medium metal
Sliding bearing frequently occurs seal failure, bearing bush abrasion problem, expensive with sealing system structure and saving for simplifying mechanical lubrication
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.General water lubricated rubber bearing structure design consider draw ratio, whether slot, rubber
The good many-sides such as bondline thickness, lath shape, joint face shape, fluting type.So the design of its structure need further
Perfect.
For rubbing surface shape, Duan Fangli thinks that the frictional behaviour in underloading or speed operation concave is significantly better than flat
Face type, and the frictional behaviour of concave bearing is the most sensitive to the change of speed and load.The test of Dai Mingcheng and simulation study
Showing, plane is better than concave or convex-surface type, is that it is more likely formed bullet-mould hydrldynamic pressure lubrication, has preferably startup
Property and low-speed running performance.Therefore from reducing critical velocity and the angle of friction factor that tail tube bearing singing sound occurs, it is recommended that make
Use plane.R.L.Daugherty etc. think that rubber layer thickness is the least, and coefficient of friction is the least, therefore from reducing water lubrication tailing axle
Hold the angle of the critical speed operating mode that singing sound occurs, it is recommended to use plane thin rubber-strip.Hardness is the least, and rubber surface rubs
Wiping coefficient the lowest, the rubber lath selecting suitable stiffness is the most critically important.Zhou Yi etc. are by emulation and Experimental comparison, result of study table
Bright, the coefficient of friction of the tank radius size of water lubricating rubber alloy bearing, rubbing surface shape and friction pair is to water lubrication rubber
The frictional noise of glue alloy bearing has considerable influence, and the shape of tank is little on the impact of bearing frictional noise.Zhou Huanhuan etc.
The hardness subregion impact effect to contact performance under three kinds of different lath types of relative analysis, result shows, hardness subregion energy
Significantly improving the contact performance of bearing, the Static Contact performance of concave lath pattern is preferable.To sum up, concave bearing capacity is relatively
Good, hence it is evident that being better than plane and convex-surface type, plane has preferable water guide effect, easily form elastohydrodynamic lubrication moisture film, convex-surface type
Be conducive to the circumference circulation of water, but bigger friction and wear can be caused, it is adaptable to the rubber lining that soft, thickness are big.
For tank type, in order to lubricate, cool down, discharge silt, water lubricating rubber tail tube bearing working surface is general all
Have tank, and the most general with U and V-type axial groove.Liu Yu et al. is for the lubricity of axially grooved water lubrication tail tube bearing
Can carry out numerical computations and analysis, result shows: fluting rear bearing circumferential pressure distribution is discontinuous, and at tank, pressure is reduced to
0, the bearing capacity of bearing reduces；And the width of groove is the biggest, number is the most, and the bearing capacity of bearing is the least.Moreover,
U-type groove is conducive to fluid to flow, and dovetail groove has preferable bearer properties, forms continuous moisture film, is not easily broken.These are all bases
In the research of basic tank, do not account for different trough-like shapes and different sink structures do not carried out contrast optimization.
Below it is all single research tank rubbing surface shape or tank type, does not consider the coupling after both combine
Group photo rings.
For common open channels bearing, due to the difference of its groove kind, bearing capacity, fluid flowing etc. are had not
Same impact, but all do not consider the distribution of bearing circumferential pressure and moisture film flowing change.Single point is carried out for single bearing
Analyse single design, do not account for result after its mixing.
For the selection in direction of slotting, helicla flute can guide sea water to carry out screw along groove, and then create
Certain spiral centripetal force, easily forms current mobility in elastic hydrodynamic lubrication, and groove produced by helicla flute
More steady, the impact on unit of axle of ship propellor affects less, but under low-speed heave-load effect, owing to helical angle again can too greatly
Its flowing is produced resistant function；Longitudinal groove, owing to output is sufficient, its lubricant effect is good, and cooling is the most reliable, mud
Sand is easily gone out outside stern bearing, and frictional work damages less, and processing and manufacturing is relatively easy.But current mobility in groove produced by it
Relatively big, unstable, easily unit of axle of ship propellor is produced bigger impact impact.General water lubricated rubber bearing all has longitudinal ditch
Groove or spiral groove, but all there is each side advantage and deficiency.Refinement for guiding gutter need to grind further
Study carefully.
For common open channels bearing, due to the difference of its groove kind, bearing capacity, fluid flowing etc. are had not
Same impact, but all do not consider the distribution of bearing circumferential pressure and moisture film flowing change.Single point is carried out for single bearing
Analyse single design, do not account for result after its mixing.
In bearing machining and installation process, technique and method are all to the follow-up work of water lubricated rubber bearing and fault
There is vital impact.The mode that general water lubricated rubber bearing many employings strip type bearing bolt is fixing, long-term
Under work alternate stress, the changing of the relative positions easily occurs, cause naval vessel afterbody to produce extraordinary noise and axle system safety problem.And when installing
It is also required to consider the eccentricity of bearing, if do not considered to be likely to result in the unbalance response of bearing rotor system.So installation process
And method could be improved.
