In an embodiment of the invention, using following principle.
Δ L=α × L × Δ T (formula 1)
Δ L-axis 10 elongation
The thermal expansion coefficient of α-axis 10
The original length of L-axis 10
Δ T-temperature variation
In fig. 4, it is assumed that the left side (not shown) of axis 10 extends to the left and is fixed (for example, being supported by fixing bearing).
When the temperature increases, axis 10 axially expands elongation, i.e. right end shown in Fig. 4 of axis 10 moves right.According to thermal expansion coefficient
The elongation of formula 1, axis 10 is directly proportional to temperature change.The signal of temperature sensor S1 is sent to hydraulic applying unit 20, liquid
Applying unit 20 is pressed to start to work.On the one hand, liquid is from hydraulic applying unit 20 by being connected to the left side (axially inner side) of bearing 60
Hydraulic drive cylinder 40 pipeline L2 flow to left side hydraulic drive cylinder 40, on the other hand, liquid is by being connected to bearing 60
The pipeline L1 of the hydraulic drive cylinder 40 on right side (axially external) returns to hydraulic applying unit 20 from the hydraulic drive cylinder 40 on right side.From
And the pressure in the hydraulic drive cylinder 40 in left side is greater than the pressure in the hydraulic drive cylinder 40 on right side, hydraulic drive cylinder 40 drives
The outer ring of bearing 60 is mobile along elongate axis direction (to the right), and (groove portion) the elongation Δ L ' of left side hydraulic drive cylinder 40 is by following
Liquid knots modification formula 2 determine.
Δ L '=Δ V/S (formula 2)
Δ V-liquid knots modification flows into the total amount (volume) of the fluid of (or outflow) hydraulic drive cylinder
S-hydraulic drive cylinder cross-sectional area
When the Δ L ' in formula 2 is equal with the Δ L in formula 1, the displacement of outer ring and stretching for axis 10 of bearing 60 are indicated
Long amount (displacement of the inner ring of bearing 60) is equal, and the movement of the outer ring of bearing 60 is appropriate.Δ L ' and formula in formula 2
When Δ L in 1 is inconsistent, the amount of movement of the outer ring of bearing 60 may be inaccurate, at this point it is possible to provide alarm.
When the temperature decreases, axis 10 will axially be shunk, and flow to phase when the flow direction of liquid is increased with temperature above
Instead, the outer ring of bearing 60 is moved in opposite direction.In simple terms, the hydraulic drive cylinder 40 in left side shortens, and right side is hydraulic
Driving cylinder 40 extends.
It should be appreciated that the movable part 42 of hydraulic drive cylinder 40 can be the form of the raised line of circular ring shape, hydraulic in Fig. 4
The groove portion of the fixed part 41 of driving cylinder 40 passed in and out for movable part 42 can be the form of the groove of circular ring shape.
Hydraulic applying unit 20 may include liquid storage portion for accommodating liquid and for driving liquid (for example, hydraulic
Oil) pump, hydraulic applying unit 20 can also include that processor for handling signal or the hydraulic applying unit 20 of control are run
Control unit.
The present invention also provides the floating ground bearing supports in bearing block for using above-mentioned floating bearing bearing base system
Method.
The effect and effect of above embodiment of the invention are briefly described below.
In general floating bearing in bearing base system, the inner ring of bearing is axially moveable with the flexible of axis, should
Movement cannot be fully transmitted to the outer ring of bearing, thus be easy to generate between inner ring and outer ring axially offset, stress etc..Big
In the case where dimensioned bearings, this problem is especially apparent.
In floating bearing bearing base system and the floating ground support shaft in bearing block of above embodiment of the invention
In the method held, friction is overcome using external hydraulic, can change initiatively driving bearing outer ring movement according to temperature, thus
Ensure floating reliability.
In the case where being provided with temperature sensor S1 and displacement sensor S2 at the same time, movable part/bearing can be verified
Whether the shift amount of outer ring is consistent with the amount of movement (stroke) of axis.Can not achieve float function (movable part cannot shift or
Shift amount is incorrect) in the case where, alarm can be provided.Thus, it is possible to be effectively prevented from the caused by that cannot float of bearing
Initial failure.Also, alarm is provided in the case where bearing fault can prevent whole equipment or system from bigger failure occur.
Since when temperature changes, external pressure (oil pressure) is started to work, it is possible to make bearing always can be from interior
Portion's stress can effectively extend the service life of bearing.
The case where measuring the displacement of movable part 42 of hydraulic drive cylinder 40 (floating distance) by displacement transducer S2
Under, the operation/stopping and the method for operation of hydraulic applying unit can be determined according to measured displacement (floating distance), it can be true
Desired displacement (i.e. consistent with elongating or shortening for axis 10) is realized on the spot.
In the present invention, when temperature changes, whole system is automatically run, therefore automatic degree is high.
The present invention is not limited to the above embodiments, and those skilled in the art can of course make above embodiment various
Deformation, without departing from the spirit and scope of the invention.
For example, Fig. 9 shows a kind of deformation of the movable part 42 of hydraulic drive cylinder 40.Instead of the movable part 42 in Fig. 4, figure
9 movable part 42 includes circular base portion 421 and (lives from circular multiple (the being illustrated as 3) projections outstanding of base portion 421
Piston part) 422.Accordingly, unshowned fixed part 41 may include the surface of circular base portion and the base portion from the annular shape
The recessed portion inwardly concaved.In the configuration shown in fig. 9, the central axis of the axis of hydraulic drive cylinder (movable part 42) and axis 10
In parallel.In the configuration shown in fig. 9, it is preferable that whole recessed portions are fluidly connected with hydraulic applying unit.
In fig. 4 it is shown that being respectively arranged a pipeline for left side hydraulic drive cylinder 40 and right side hydraulic drive cylinder 40.So
And pipeline can also be set in multiple positions of each hydraulic drive cylinder 40, it is hydraulic drive from multiple position and a plurality of pipeline
Dynamic cylinder 40 supplies liquid, or extracts liquid out from hydraulic drive cylinder 40.
In the above-described embodiment, hydraulic applying unit is controlled by measuring the temperature of axis 10.However, the present invention is not limited to
This.For example, it is also possible to control hydraulic application by the position change (displacement) for the part corresponding with bearing 60 for measuring axis 10
Portion 20.
In the above-described embodiment, the outer ring of bearing is driven using hydraulic.However, the invention is not limited thereto.For example, also
Other driving devices such as motor can be used to drive the outer ring of bearing.However, it is to be appreciated that in setting such as motor
In the case where driving device, pipeline L1, L2 can be replaced with electric wire.
