Description
Technical field
The invention belongs to mechanical design field, particularly to a kind of Intelligent state adjustable dislocation plain bearing arrangement, its
Be applicable under time-varying working condition radially slides support.
Background technology
Sliding bearing stable working, reliable, noiselessness, if can guarantee that hydrodynamic lubrication condition, relative motion surface quilt
Lubricating film separates and does not produce directly contact, thus greatly reduces friction and wear.Although under general operating mode, such as lathe,
The occasions such as reduction box automobile are scrolled bearing and replace, but in a lot of important events, such as generating set, steam turbine, rolling mill, at a high speed
The fields such as main shaft still account for critical role.Sliding bearing bears the direction of service load by it, can be divided into bush(ing) bearing and push away
Power sliding bearing；Bush(ing) bearing can be divided into common circle watt, elliptic bush, dislocation watt, heavy wool leaf and tilting bush by tile fragment form
Deng；And thrust bearing can be divided into fan-shaped fixing watt, Circular Tilt-pad and Sector Tilting Pad etc..In conventional slide design bearing,
It is generally directed at one or more duties and is designed.But in plant equipment actual motion, the work of sliding bearing
Condition is probably time dependent, such as rotation speed change, sinusoidal excitation, temporary impact, irregular dynamic load etc..A certain special parameter
Variable working condition when fixing watt of dislocation sliding bearing often cannot adapt to this, owing to bearing shell is fixed, so can not be according to various time-varying
Operating mode and adjust dislocation degree parameter.Therefore, time, variable working condition the most then can cause the abrasion of sliding bearing, the vibration of rotor-support-foundation system, contracting
Short equipment life, heavy then cause tile kilning, the major accident such as seize, and once nucleus equipment damages, corresponding production line or unit
Will shut down, cause tremendous economic to be lost.
When therefore developing a kind of being applicable to, the sliding support technology of variable working condition, has important economic worth and realistic meaning.
Summary of the invention
It is an object of the invention to provide a kind of Intelligent state adjustable dislocation bearing arrangement, this sliding bearing may solve to solve
Existing bush(ing) bearing may be only available for the shortcoming of particular job situation, is particularly suited for working condition and changes over situation
Under radially slide support.
The technical scheme is that and be achieved in that:
Including state adjustable dislocation sliding bearing structure and detecting and controlling system two parts；The adjustable dislocation of state is slided
Bearing is made up of bearing on watt and lower half bearing, the two mounted in pairs, and lower half bearing is fixed on pedestal, bearing on watt and inclination
Slide block is connected with back-moving spring, and bearing on watt can transverse translation；In detecting and controlling system, horizontal displacement sensors is with perpendicular
Straight displacement transducer is arranged near dislocation sliding bearing, is connected with controller, and controller is connected with servomotor, sloping slide
It is connected with bearing on watt.
Horizontal displacement sensors and vertical displacement sensor are 90 degree and are mounted opposite.
Described controller controls servomotor, servomotor be connected with sloping slide by turn-screw.
Bearing on watt is connected with back-moving spring.
The invention have the advantages that:
1. variable working condition when bearing goes for.
2. the attitude of bearing is by being automatically adjusted, and reaches optimum duty.
3. the duty of bearing can be monitored, if not reaching job requirement, can automatic alarm.
The most whole device has the advantage of feedback, can effectively control the bearing working caused owing to working condition changes
The situation that state is bad.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
1 it is the diameter of axle, 2 is bearing on watt, 3 is servomotor, 4 is turn-screw, 5 is sloping slide, 6 is controller, 7 is
Horizontal displacement sensors, 8 be vertical displacement sensor, 9 be lower half bearing, 10 be back-moving spring.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
One Intelligent state of the present invention adjustable dislocation plain bearing arrangement, this device includes that the adjustable dislocation of state is slided
Bearing arrangement and detecting and controlling system two parts；Wherein state adjustable dislocation sliding bearing is divided into upper and lower two watts, and the two is paired
Installing, lower half bearing fixes, and bearing on watt can transverse translation within the specific limits；In detecting and controlling system, displacement sensing
Device is arranged near dislocation sliding bearing, is connected with status monitoring controller, and controller is connected with servomotor, by servomotor
Being connected with sloping slide by turn-screw, sloping slide is connected with bearing on watt；Control in real time, be automatically adjusted sloping slide
Position changes the position of bearing on watt lateral shift, thus adjusts the duty of sliding bearing in real time, exchanges work during to adapt to
The requirement of condition.
In apparatus of the present invention, if outside working condition changes over, the operation conditions of axle journal can be by displacement transducer
Being acquired, the displacement vibration information of axle journal is analyzed by controller, controller be automatically adjusted actuator, by regulation
The lateral attitude of bearing on watt, changes bearing dislocation degree, can change bearing working state, and during to reach any, variable working condition is glided
Dynamic bearing is all in the purpose of good working state.
As it is shown in figure 1, Intelligent state adjustable dislocation bearing is made up of bearing on watt 2 and lower half bearing 9, both pacify relatively
Dress, lower half bearing 9 is fixing, and bearing on watt 2 can be in horizontal certain limit under the interaction of sloping slide 5 and back-moving spring 10
Interior movement.Change bearing dislocation degree by changing bearing on watt 2 lateral attitude, thus change oil film bearings thickness and shape
Shape, and then change sliding bearing working condition.Displacement transducer 7 and 8 is positioned near bearing and in 90 degree of phases centered by the diameter of axle 1
To installation, when operating mode changes over, displacement transducer 7 and 8 gathers position and the vibration signal of the diameter of axle 1；Controller 6 basis
Sensor 7 and 8 records position and the vibration signal of the diameter of axle 1, analyzes and judges the working condition of bearing and draw actively controlling party
Case, sends the forward or reverse of real-time control signal regulation servomotor 3, via turn-screw, by the rotation of servomotor 3 main shaft
The dynamic linear motion being converted to sloping slide 5 of transhipment；Sloping slide 5 and the contact of incline plane of bearing on watt 2, then sloping slide 5 exists
Vertical direction moves the transverse shifting being converted into bearing on watt 2, thus real-time active regulation sliding bearing dislocation degree is to control oil
Film thickness and shape, change bearing working situation, improve bearing running status；After adjustment the position of the diameter of axle 1 and vibration continue by
Displacement transducer 7 and 8 measures, and carries out bearing working condition further actively controlling and regulating in real time, with ensure time
Variable working condition lower bearing is constantly in good working state；Once bearing working is in bad condition, controller 6 sends alarm automatically.
