Repair expense, it is therefore desirable to which a kind of tilting thrust bearing device is solving the problem.
The content of the invention
This utility model provides a kind of tilting thrust bearing device of adjust automatically oil film thickness, it is intended to solve existing
Easily there is the problem of unbalance loading in tilting thrust bearing.
For achieving the above object, embodiment of the present utility model is pushed away there is provided a kind of tilting bush of adjust automatically oil film thickness
Power bearing arrangement, it is characterised in that：Including oil film thickness can adjust automatically tilting thrust bearing and control system:
The oil film thickness can the tilting thrust bearing of adjust automatically include runner plate, some tile fragments and base；If described
Dry tile fragment is located between runner plate and base；There are some screwed holes on the base, be distributed in by some tile fragments；
The control system includes some resistance strain-gauge transducers being pasted onto on some tile fragments, resistance-strain chip
Sensor connects the input of resistive voltage transducer, and the outfan of resistive voltage transducer connects the input of analog-digital converter
End, the outfan of analog-digital converter connect the input of controller, and the outfan of controller then connects the defeated of fuel-injection valve for high-pressure
Enter end.
Further, controller can be with by analog-digital converter, resistive voltage transducer and resistance strain-gauge transducer
Obtain the load that some tile fragments are subject to.
Further, the bottom of fuel-injection valve for high-pressure is tightened against in some screwed holes, easy for installation；To prevent tilting bush thrust
Oil in bearing is revealed along fuel-injection valve for high-pressure, and each fuel-injection valve for high-pressure is equipped with packing ring.
Further, when oil film thickness can be in the tilting thrust bearing of adjust automatically the power that is subject to of certain block tile fragment than which
When the power that his tile fragment is subject to is greatly to the marginal value being more than in controller, controller sends finger to the fuel-injection valve for high-pressure near the tile fragment
Order, fuel-injection valve for high-pressure can then spray appropriate hydraulic oil, and so as to increase the oil film thickness between the tile fragment and runner plate, and then reduction should
Suffered power on tile fragment.
Using the technical solution of the utility model, the utility model simple structure only need to be in original tilting bush thrust axis
Add a set of control system and fuel-injection valve for high-pressure on the basis of the frame for movement held, and can quickly find and solve tilting bush to push away
The unbalance loading problem that power bearing is present, largely extends the working life of tilting thrust bearing.
Description of the drawings

The structural representation of example.
In accompanying drawing：
1st, runner plate；2nd, tile fragment；3rd, base；4th, resistance strain-gauge transducer；5th, resistive voltage transducer；6th, modulus turns
Parallel operation；7th, control；8th, fuel-injection valve for high-pressure；9th, packing ring；10th, screwed hole.
Specific embodiment
Fully to explain the technical solution of the utility model, illustrate below in conjunction with accompanying drawing.
As shown in figure 1, embodiment of the present utility model provides a kind of tilting bush thrust axis of adjust automatically oil film thickness
Bearing apparatus, the device include oil film thickness can adjust automatically tilting thrust bearing and control system.
The oil film thickness can the tilting thrust bearing of adjust automatically include runner plate 1, some tile fragments 2 and base 3；It is described
Some tile fragments 2 are located between runner plate 1 and base 3；There are some screwed holes 10 on the base 3,
It is distributed in by some tile fragments 2.
The control system includes some resistance strain-gauge transducers 4 being pasted onto on some tile fragments 2, resistance strain gage
The input of the connection resistive voltage of formula sensor 4 transducer 5, the outfan connection analog-digital converter 6 of resistive voltage transducer 5
Input, the outfan of analog-digital converter 6 connect the input of controller 7, and the outfan of controller 7 then connects high pressure fuel injector
The input of mouth 8.
During this utility model is arranged, controller is sensed by analog-digital converter, resistive voltage transducer and resistance-strain chip
Device can obtain the load that some tile fragments are subject to.
This utility model arranges the bottom of mesohigh atomizer and is tightened against in some screwed holes, easy for installation；For prevent can
The oil inclined in watt thrust bearing is revealed along fuel-injection valve for high-pressure, and each fuel-injection valve for high-pressure is equipped with packing ring.
Specifically, in order to fuel-injection valve for high-pressure can be worked exactly, it is not by fuel-injection valve for high-pressure in this utility model device
The centre position of Habenaria dipionema Sohltr block is placed on, and is closer to one of tile fragment, and the spray orifice direction of fuel-injection valve for high-pressure is more leaned on
That side of near tile fragment；And for bearing energy normal work, the height of fuel-injection valve for high-pressure is controlled under tile fragment upper horizontal plane,
Runner plate is directly contacted with atomizer so as to avoid fuel-injection valve for high-pressure too high.
The course of work of the tilting thrust bearing device of the adjust automatically oil film thickness is as follows：
Oil film thickness can adjust automatically tilting thrust bearing work when, be pasted onto on tilting thrust bearing tile fragment
Deformation quantity on each tile fragment for obtaining can be converted into resistance value and pass to resistive voltage conversion by resistance change sheet type sensor
The magnitude of voltage for obtaining, so as to obtain a series of magnitude of voltage, then the utilization by analog-digital converter, is converted into numerical value, most by device
Afterwards this series of numerical value is sent in controller, if certain numerical value is more than the marginal value of controller setting, controller is sent out
Go out instruction so that the fuel-injection valve for high-pressure near the tile fragment is in "on" position, so as to spray appropriate lubricating oil to the tile fragment,
So that the oil film thickness of the tile fragment becomes big, reduce the load of the tile fragment.If conversely, each numerical value is both less than facing in controller
Dividing value, then fuel-injection valve for high-pressure is then in obstructed electricity condition, state of the tilting thrust bearing in normal work.
