Description
Technical field
The present invention relates to sliding bearing technical field, more particularly, to a kind of winding off spindle half-watt bushing and preparation technology.
Background technology
Bearing shell is the part that sliding bearing contacts with axle, unusual light, typically with high-abrasive material systems such as bronze, antifriction alloys
Become, under special circumstances, can be made with timber, plastics or rubber.Also it is " axle bush ", be shaped as the semi-cylindrical of tiles.Sliding
During dynamic bearing work, between bearing shell and rotating shaft, require have one layer of very thin oil film to play lubrication.If insufficient lubrication, bearing shell with
Direct friction is there is, friction can produce very high temperature, be sufficient to burn out device between rotating shaft.Bearing shell is also possible to due to load
Excessive, temperature is too high, lubricating oil has impurity or viscosity is abnormal etc., and factor causes tile kilning.After tile kilning, sliding bearing just damages.
The bearing that sliding bearing works under sliding friction.Sliding bearing stable working, reliability, noiseless.Under the conditions of hydrodynamic lubrication,
Separately be there is not directly contact by lubricating oil in slidingsurface, can also greatly reduce friction loss and surface abrasion, oil film is also
There is certain vibration absorption ability.
Spool is used in a large number on metallurgical equipment (milling train such as steel, copper, aluminum, stretch bending are rectified) and band Automatic production line, spool
Operation principle is to push away contracting motion by the radial direction of the internal axial wedge of spool, realizes the harmomegathus motor function of spool.Spool liner plate is
Ensure the key component of axial wedge and radial direction wedge path and dimension precision requirement motion according to the rules.Traditional spool liner plate is
Oil-way is machined with liner plate rubbing surface, oil-way is connected with oilhole, by oilhole to oil-way oiling, oil-way
Oil be supplied to liner plate and the rubbing surface (liner plate work surface) of spool is lubricated.Because spool is often in the environment of high temperature, many dirt
Lower continuous work, high temperature dries lubricant grease, and dust blocking oilhole etc. causes oily inconvenience, makes traditional spool work
Often move the phenomenon such as dumb and stuck in work, cause to stop production and spool damages.So, a kind of resistant to elevated temperatures profit certainly of research
Sliding Sliding bush lining becomes one of technical problem.
Chinese patent 201520952169.7 provides a kind of plain bearing bush insulation system and bearing shell, including having poured
The bearing alloy of babbit and bearing shell unbaked tile；Also include one kind and be provided with v connected in star；Or it is provided with 1 millimeter to 2 millimeters glass fibers
Dimension silk layer；Or the outer surface of glass fiber layer sets Teflon layer；Or constitute high fiber structure by several secondary fiber structures
And there are several stackings fibrous base layers constitute bearing shell technical scheme.It is poly- using pasting that it overcomes conventional insulator bearing
Tetrafluoroethene thin film is isolated with bearing shell, realizes cut-out path of shaft current；Lead to insulation film in installation and maintenance process easily
Impaired, and the renovation technique after damage is considerably complicated, needs special tooling, thus causing the defects such as maintenance difficult, equipment scrapping.It
It is suitable for the insulation of plain bearing bush used in all kinds of engineerings；It is particularly suitable for mine, electric power, colliery, metallurgy, traffic, chemical industry, water
Profit, the insulation of the plain bearing bush of the supporting large rotating machinery of the industry such as lathe, ship；But the axle that the prior art provides
The workplace of watt not competent high temperature.Chinese patent 201420497622.5 provides a kind of sliding bearing and its bearing shell, institute
State bearing shell and be formed as arc, the outside wall surface of described bearing shell be provided with multiple along its circumferentially spaced arrangement and radially to extension
The projection stretched.According to bearing shell of the present utility model, bearing shell is touched more closely with watt seated connection, and when axle is coordinated with bearing shell, is conducive to
Ensure the concordance in the gap between bearing shell and axle, reduce the abrasion of bearing shell, extend the service life of bearing shell, meanwhile, bearing shell with
Contact area between watt seat reduces, and improves footprint pressure, the contact pressure required for watt seat is less, thus bearing shell does not need
It is high that larger radius is set, after bearing shell is assembled with watt seat, easily reaches the aperture value of design, and also reduce the assembling of bearing shell
The magnitude of interference, reduces the stress of watt seat, and a watt seat is not easy to be deformed, and the structure of watt seat is more stable, it is possible to reduce electromotor
Reliability test and checking work, improve production efficiency, reduce production cycle and cost；But the prior art also could not solve
Bearing shell determine high temperature resistant self-lubricating problem.
