Bearing.
Background technique
One of main support pattern as rotor, sliding bearing in engineering field using very extensive, and roll
Bearing is compared, and sliding bearing has the obvious advantages such as large carrying capacity, strong shock resistance and damping characteristic be good.Sliding bearing work
When making, if it is possible to guarantee sufficient lubricating oil supply, so that the surface mutually slided is separated by lubricating oil without direct
Contact, so that it may greatly reduce friction loss and surface abrasion, even be eliminated abrasion；In addition, the lubricating oil film in sliding bearing
With certain vibration absorption ability, this is all highly beneficial to the stability and precision that improve rotor operating.
Bush(ing) bearing is one of sliding bearing important kind, and the application in rotating machinery is equally very wide
It is general, bush(ing) bearing in actual use, especially high speed or severe duty under because in bearing lubricating oil squeeze
Pressure and shearing motion are violent, are frequently encountered the exceeded problem of lubricating oil temperature.Engineering in practice, generally require sliding bearing
Interior highest oil temperature is no more than 90 DEG C, because excessively high oil temperature can bring detrimental effect to jewel and lubricating oil itself, has
The risk for causing sliding bearing to fail.Oil guard is set between bearing shell adjacent in bush(ing) bearing, utmostly ground resistance
Gear takes part in bearing shell lubrication, temperature higher hot oil enters next bearing shell, is there is lubricating oil temperature in reduction bearing
One of effect approach.The problems such as generally existing bad adaptability of traditional oil guard and the unstable oily effect of gear, this is seriously constrained
Application of the bush(ing) bearing under the bad working environments such as high speed and heavy duty, becomes must solve in bush(ing) bearing popularization one
A problem.
Summary of the invention

The output of device 10 processed is connected with the electric control end of piezoelectric actuator 8, and the end of gear oil clot 5 is arranged in piezoelectric actuator 8, and piezoelectricity is made
Screw 7 is equipped on the outside of dynamic device 8, screw 7 is fixed after being used for the position in adjustment piezoelectric actuator 8, PID active controller 10
It is mounted in external control cabinet.
The displacement sensor 9 and gear oil clot 5 flushly mounts with, and guarantees that the distance that displacement sensor 9 measures is equal to gear oil
The distance between block 5 and axle journal.
The displacement sensor 9 measures gear the distance between oil clot 5 and axle journal, is transferred to PID active controller 10,
PID active controller 10 and the distance of Qi Nei setting compare, and control the electric signal being output on piezoelectric actuator 8, piezoelectricity
Actuator 8 generates required displacement under the action of electrical signals, in real time adjustment gear the distance between oil clot 5 and axle journal, makes gear oil
The distance between block 5 and axle journal are automatically kept as steady state value.
The bush(ing) bearing is set altogether there are two oil guard, and two gears the distance between oil clots 5 and axle journal are by two
A displacement sensor 9 measures respectively, and is adjusted separately by two piezoelectric actuators 8, can adapt to axle journal axis and radially slides
The not parallel operating condition of bearing axis.
The beneficial effects of the present invention are:
Gear oil clot 5 can effectively stop to take part in that a bearing shell lubricates, the higher hot oil of temperature enters next bearing shell,
The temperature of lubricating oil is substantially reduced in bearing.
Displacement sensor 9 can keep off the distance between oil clot 5 and axle journal with real-time measurement, and pass through PID active controller 10
Piezoelectric actuator 8 is fed back, piezoelectric actuator 8 generates displacement and to adjust gear the distance between oil clot 5 and axle journal in real time, is allowed to begin
Setting value is remained eventually, can effectively block hot oil and gear oil clot 5 and axle journal is not in contact, by closed-loop control,
The gear oil effect that oil guard can be automatically adjusted well solves under high speed or severe duty oil temperature mistake in bush(ing) bearing
High problem effectively expands the application range of bush(ing) bearing.

Specific embodiment
It elaborates with reference to the accompanying drawings and examples to the present invention.
Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4, a kind of bush(ing) bearing with automatic adjustment oil guard, including lower axle
Seat 1 and top chock 3 are held, lower bearing 2 and top bearing shell 4,1 He of step are separately installed in step 1 and top chock 3
Lower bearing 2 forms bush(ing) bearing lower half, and top chock 3 and top bearing shell 4 form bush(ing) bearing upper half, radially sliding
In bearing lower half and upper half, it is provided with oil inlet 6, one oil guard is respectively installed in the upstream edge of oil inlet 6；
The oil guard is made of gear oil clot 5, displacement sensor 9, piezoelectric actuator 8 and screw 7, displacement sensor
9 flushly mount with gear oil clot 5, guarantee that the distance that displacement sensor 9 measures is equal to gear the distance between oil clot 5 and axle journal, are displaced
The signal output of sensor 9 is connected with the input of PID active controller 10, the output and piezoelectric actuating of PID active controller 10
The electric control end of device 8 connects, and the end of gear oil clot 5 is arranged in piezoelectric actuator 8, under the action of piezoelectric actuator 8, keeps off oil clot
5 move together with displacement sensor 9, and gear the distance between oil clot 5 and axle journal are adjusted to setting value in real time, guaranteed good
Keep off oily effect；Screw 7 is equipped on the outside of piezoelectric actuator 8, screw 7 for adjusting the position of piezoelectric actuator 8 in a certain range
After be fixed, PID active controller 10 is mounted in external control cabinet.
The bush(ing) bearing is set altogether there are two oil guard, and two gears the distance between oil clots 5 and axle journal are by two
A displacement sensor 9 measures respectively, and is adjusted separately by two piezoelectric actuators 8, can adapt to axle journal axis and radially slides
The not parallel operating condition of bearing axis.
The working principle of the invention is:
Referring to Fig. 4, displacement sensor 9 measures gear the distance between oil clot 5 and axle journal, is transferred to PID active controller 10,
PID active controller 10 and the distance of Qi Nei setting compare, and control the electric signal being output on piezoelectric actuator 8, piezoelectricity
Actuator 8 generates required displacement under the action of electrical signals, in real time adjustment gear the distance between oil clot 5 and axle journal, makes gear oil
The distance between block 5 and axle journal are automatically kept as steady state value.In this way, can both guarantee the oily effect of good gear, diameter is effectively reduced
Oil temperature into sliding bearing, and mill can be touched to avoid between gear oil clot 5 and axle journal.
It is higher that the gear oil clot 5 for being mounted on 6 upstream edge of oil inlet can effectively stop to take part in bearing shell lubrication, temperature
Hot oil enter next bearing shell, allow most hot oils to release from the both ends of the surface of bearing, be returned directly to lubricating system carry out it is cold
But.Cooling cold oil is completed, next bearing shell is entered by oil inlet 6, executes its lubrication task.Therefore, lubricating oil in bearing
Temperature will necessarily be substantially reduced.
In actual work, the position of axle journal is bound to be constantly occurring variation bush(ing) bearing, therefore, keeps off 5 He of oil clot
The distance between axle journal is that a dynamic is measured, and displacement sensor 9 can keep off the distance between oil clot 5 and axle journal with real-time measurement, and
Piezoelectric actuator 8 is arrived by the feedback of PID active controller 10, piezoelectric actuator 8 generates displacement to adjust gear oil clot 5 and axis in real time
The distance between neck is allowed to remain setting value, can effectively block hot oil and gear oil clot 5 and axle journal is not sent out
Raw contact.By closed-loop control, the gear oil effect of oil guard can be automatically adjusted, is well solved under high speed or severe duty
In bush(ing) bearing the problem of high oil temperature, effectively expand the application range of bush(ing) bearing.
