Description
Technical field
The utility model belongs to technical field of motors, is a kind of high efficiency heat radiation type machine shaft self-lubricating plain bearing.
Background technology
In existing technology, rub between self-lubricating motor bearing shell and shaft generation amount of heat mainly by bearing block
With the natural convection air in environment --- heat exchange and shed, it is whole strong in order to ensure bearing block in the design of bearing block
Degree generally leads to the profit in oil sump using cast iron monoblock cast bearing block and cooling fin since the coefficient of heat conduction of cast iron is relatively low
Oil temperature and the temperature difference of bearing block outer surface and cooling fin are larger, in addition heat-delivery surface temperature distributing disproportionation on entire bearing block
It is even, bearing block Natural Heat Convection efficiency is thus greatly reduced, so that the heat that bearing generates is not shed in time, easily causes
Lubricating oil high-temp is rotten, and bearing bush temperature is caused to increase, and shaft generates metal friction with bearing shell when serious, causes bearing damage, electricity
Machine can not use.
Utility model content
The purpose of this utility model is to provide a kind of radiating efficiency, ensures and extend the service life of bearing or even motor
High efficiency heat radiation type machine shaft self-lubricating plain bearing.
Technical solution is used by realize the purpose of this utility model：The bearing include bearing block, bearing shell, oil ring,
Internal bearing cover and bearing cover, wherein bearing shell is located in bearing block, and is set with and is connected on machine shaft, in the middle part of Pad radius
Equipped with groove, oil ring is placed with built in groove, oil ring is suspended in shaft, and is rotated with shaft, the left and right both sides of bearing block
It is connected separately with internal bearing cover and bearing cover by clamping screw, the bottom that cavity is constituted between two lids and bearing block is below
Bearing oil bit line is provided with seal groove and O-shaped sealing in the step end face root of internal bearing cover, bearing cover and bearing block cooperation
Item, the lower section of bearing block are equipped with axial backflow through hole and oil sump, and backflow through hole is less than bearing oil bit line, by backflow through hole by axis
Oil sump in bearing is connected to the cavity of internal bearing cover and bearing cover.
The internal bearing cover and bearing cover are copper alloy or Al-alloy products.
According to high efficiency heat radiation type machine shaft self-lubricating plain bearing made of said program, when motor operation, hang
The oil ring hung on machine shaft is rotated with shaft, and the lubricating oil in oil sump can be brought into the working face of shaft and bearing shell,
It to play self-lubricating function, and is let out by end, the higher lubricating oil of temperature is made to flow into the cavity and bearing cover of internal bearing cover
Cavity, then conducted by the surface radiating of internal bearing cover, bearing cover, it conducts heat in corresponding space environment, it is cooling
Lubricating oil afterwards is flowed back by backflow through hole in oil sump, and is brought into the working face of shaft and bearing shell again by oil ring, plays profit
Sliding and cooling effect forms the cyclic process lubricate, lubricate again, cooling down again, to efficiently solve current self-lubricating sliding
The low problem of radiating efficiency existing for bearing.The bearing has reasonable in design, radiating efficiency height, highly practical advantage.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific implementation mode
Referring to Fig. 1, the high efficiency heat radiation type machine shaft self-lubricating plain bearing of the utility model, which includes bearing
Seat 1, bearing shell 2, oil ring 3, internal bearing cover 5 and bearing cover 6, wherein bearing shell 2 is located in bearing block 1, and is set with and is connected to motor
In shaft 4, it is equipped with groove in the middle part of 2 internal diameter of bearing shell, is placed with oil ring 3 built in groove, oil ring 3 is suspended on machine shaft 4, and with electricity
Machine shaft 4 rotates, and the left and right both sides of bearing block 1 are connected separately with internal bearing cover 5 and bearing cover 6 by clamping screw 11, and two
The bottom that cavity is constituted between lid and bearing block 1 is below bearing oil bit line 12, in internal bearing cover 5, bearing cover 6 and bearing block
The step end face root of 1 cooperation is provided with seal groove and O-type seal, it can be ensured that the lubricating oil in bearing will not be leaked to bearing
It is external.The lower section of bearing block 1 is equipped with axial direction backflow through hole 1-1 and oil sump 1-2, backflow through hole 1-1 and is less than bearing oil bit line 12, leads to
Backflow through hole 1-1 is crossed to be connected to the oil sump 1-2 in bearing block 1 with the cavity of internal bearing cover 5 and bearing cover 6.
Using the self-lubricating plain bearing, when motor operation, the oil ring 3 being suspended in shaft 4 is revolved with shaft 4
Turn, the lubricating oil in oil sump 1-2 can be brought into the working face of shaft 4 and bearing shell 2, after playing lubricating action, is let out by end, make temperature
It spends higher lubricating oil and flows into internal bearing cover cavity 9, bearing cover cavity 10, and pass through internal bearing cover 5, the table of bearing cover 6
Face heat dissipation conduction, conducts heat in corresponding space environment, lubricating oil after cooling flows back into oil by backflow through hole 1-1
It in the 1-2 of pond, and is brought by oil ring 3 into the working face of shaft 4 and bearing shell 2 again, plays lubrication and cooling effect, form lubrication, cold
But the cyclic process, lubricated again, by the ringing of lubricating oil, the heat that machine shaft 4 and 2 working face of bearing shell can be generated
Major part is rejected heat at least partially through bearing block 1 in the air around bearing block by bearing cover 5 and internal bearing cover 6.At this
In case, the lubricating oil in oil sump 1-2 is in direct contact with the internal bearing cover 5 of copper alloy or aluminium alloy, bearing cover 6, on the one hand may be used
Reduce the lubricating oil temperature and 1 outer surface of bearing block and the temperature difference of cooling fin, another aspect internal bearing cover 5, bearing in oil sump 1-2
The high heat-conduction coefficient characteristic of outer cover 6 can make the heat-delivery surface Temperature Distribution entirely covered relatively uniform consistent, which thereby enhance scattered
Mean temperature difference between hot surface and air increases heat loss through convection efficiency, significantly reduces the work of self-lubricating plain bearing
Make temperature, in addition the high-strength characteristic of cast-iron chock 1, while proof strength, high, simple in structure with radiating efficiency,
The distinguishing features such as easy to manufacture, of low cost.
The technical solution of the utility model is not restricted in the range of embodiment described above, the skill of not detailed description
Art content is known technology.
