The accident such as split to happen occasionally, be only capable of carrying out actual measurement, the actual axial force of online accurate measurement large scale equipment by test method(s)
It is great to the security sense of raising product operation.But for bearing uneven axle using tilting thrust bearing and thrust disc
To the large rotating machinery of power, its bearing housing is complicated, space is limited, the swingable property of bearing tile in addition, can not select
Conventional structure flexible member tests axial force；So as to can not accurately carry out the on-line checking of axial force.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is that solution axial force of rotating machinery can not
The problem of carrying out online accurate measurement, there is provided a kind of tilting thrust bearing that can detect axial force of rotating machinery, Neng Gou
On the basis of the assembling structure for not changing tilting thrust bearing, the online accurate measurement of axial force is realized.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is such：One kind can detect rotation
The tilting thrust bearing for tool axial force of making a connection, including bearing body, thrust disc, tilting pad, swing block, carrier and end
Lid；The thrust disc, tilting pad, swing block and carrier are mounted in bearing body, and pass through end cap locking positioning；Its
In, tilting pad, swing block and carrier are symmetrically distributed in the both sides of thrust disc；The end face of the carrier has several piece arc
Crushing block, the crushing block on two carriers are close together with bearing body and end cap respectively；It is characterized in that：In the outer of crushing block
Side is provided with a groove, makes the gap that 4-6mm is formed between crushing block and carrier；Pasted in the inner side of crushing block and be provided with work
Make foil gauge.
This programme, using cantilever beam tension and compression deformation principle, proposes on the basis of tilting thrust bearing carries dish structure
A kind of novel axial power test structure, opening position larger in axial strain variable quantity and stable（At crushing block）Application work
Foil gauge, strain variation amount are minimum（On carrier）Opening position sticking temperature dummy gauge, with external circuitry form measure
System, the Light deformation progress actual measurement of axial force is produced by extruding.
Further, on the carrier between adjacent two crushing block, stickup is provided with temperature-compensating foil gauge.
Further, the crushing block is 3 pieces, and is uniformly distributed within one week around carrier.
Further, the end of the carrier is close to central hole, provided with around the centre bore annular groove of one week, the work
Stretched into as foil gauge in the annular groove.
Compared with prior art, the utility model has the following advantages that：
1st, in the case where not changing bearing assembling structure, the installation of normal rated thrust tile fragment can be ensured, use and exchange.
2nd, it can slow down the responsive to axial force time, reduce bearing temperature, improve bearing life.
3rd, the on-line monitoring of axial force can be realized, and measuring accuracy, high sensitivity, scope are wide.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment：Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of tilting thrust bearing that can detect axial force of rotating machinery,
Including bearing body 1, thrust disc 2, tilting pad 3, swing block 4, carrier 5 and end cap.The thrust disc 2, tilting pad 3,
Swing block 4 and carrier 5 are mounted in bearing body 1, and pass through end cap locking positioning；Wherein, tilting pad 3, the and of swing block 4
Carrier 5 is symmetrically distributed in the both sides of thrust disc 2.The end face of the carrier 5 has several piece arc crushing block 6, the extruding
Block 6 is 3 pieces, and is uniformly distributed within 5 one weeks around carrier；Crushing block 6 on two carriers 5 is close to bearing body 1 and end cap respectively
Together.
A groove is provided with the outside of crushing block 6, makes the gap that 4-6mm is formed between crushing block 6 and carrier 5；This
Sample, when carrier 5 receives responsive to axial force, crushing block 6 can produce deformation, and due to being deposited between crushing block 6 and carrier 5
In gap, therefore deformation quantity can maximumlly reflect in the inner side of crushing block 6.Paste and be provided with the inner side of crushing block 6
Working strain gauge 7；Pass through working strain gauge 7, you can quickly and accurately the deformation quantity of crushing block 6 is detected, it is outer coordinating
Boundary's circuit, so as to detect the axial force suffered by bearing exactly.During practice of construction, due to the width on work strain side
Degree is wider（For 10mm or so）, and the thickness of crushing block 6 is smaller（Only 8mm or so）, therefore, the end of the carrier 5 is leaned on
Nearly central hole, provided with being stretched into around the centre bore annular groove of one week, the working strain gauge 7 in the annular groove, the annular groove
Depth and the thickness sum of crushing block 6 are more than the width of working strain gauge 7（As more than the depth 2mm of annular groove）, so as to
It is enough to be preferably operated the assembling of foil gauge 7, and its accuracy of measurement is not influenceed.
In specific implementation process, on the carrier 5 between adjacent two crushing block 6, stickup is provided with temperature-compensating strain
Piece 8；So as to further improve the accuracy of axial force detection.
This programme, using cantilever beam tension and compression deformation principle, proposes on the basis of the structure of tilting thrust bearing carrier 5
A kind of novel axial power test structure, opening position larger in axial strain variable quantity and stable（At crushing block 6）Application work
Foil gauge 7, strain variation amount are minimum（On carrier 5）Opening position sticking temperature dummy gauge 8, with external circuitry form survey
Amount system, the Light deformation progress actual measurement of axial force is produced by extruding.
It is last it should be noted that above example is only illustrating the technical solution of the utility model rather than restriction technologies
Scheme, it will be understood by those within the art that, those are modified or are equal to the technical solution of the utility model
Replace, without departing from the objective and scope of the technical program, all should cover among right of the present utility model.
