Description
Technical field
The invention belongs to technical field of bearings, and in particular to a kind of rolling bearing of band from monitoring system.
Background technology
Bearing is all indispensable basic building block in fields such as machinery, vehicle, Aero-Space, steamer and the energy, simultaneously
It is also one of most flimsy part in transmission system, the 30% of rotating machinery fault is triggered by bearing failure.Therefore,
Bearing condition monitoring has caused the great attention of people with Incipient Fault Diagnosis.The on-line monitoring of bearing state progressively turns into
The indispensable technology in the fields such as high-rating generator, steamer, high ferro and airborne vehicle, the index of required monitoring includes temperature, shaken
Dynamic, rotating speed and noise etc..Early stage bearing monitor system is mainly external hanging type, one of drawback be between sensor and signal source away from
From non-contacting indirect measurement farther out, is belonged to, error is larger.In recent years, people propose various forms of embedded in succession again
Monitoring system, though measurement accuracy and accuracy problem can be solved, needs to change the structure or its integrality of relevant device, so as to
Sensing and monitoring system, the problems such as this not only easily causes the stress concentration of equipment component, in some complicated or skies are installed
Between be also to realize in limited equipment；It is the most key, when monitoring system needs to rotate with bearing internal external circle
When, it not will pass through line powered, and it is very short using battery use time of powering.Therefore, existing bearing monitor system is also substantially
For regular, indirect non-cpntact measurement, it is difficult to timely and accurately obtain the running status of bearing.In view of this, there has been proposed
The confession pyroelectric monitor bearing of diversified forms, power generation performance when its greatest problem is different rotating speeds differs greatly, effective band is narrow,
Reliability is low.
The content of the invention
The present invention proposes a kind of rolling bearing of band from monitoring system, and the embodiment that the present invention is used is：From monitoring circle
Cone bearing includes inner ring, roller, outer ring, sensor, circuit board, pressure ring, transducer, camshaft and sealing ring；Toroidal membrane will
Outer ring is separated into left chamber and right chamber, right chamber and is provided with inner ring through roller；Circuit board and sensor are installed, electricity on toroidal membrane
Road plate is placed in left chamber；The axle platform of camshaft is enclosed in the endoporus of inner ring, and the shaft shoulder on camshaft is arranged on inner ring through screw,
Sealing ring is crimped between the shaft shoulder and toroidal membrane；Camshaft is provided with cam path；Through screw and pressure on the inwall boss of outer ring
Ring is provided with transducer, and transducer is placed in left chamber, and transducer is formed by substrate and PZT film bonding, and PZT film is installed on the right side,
The free end of transducer is provided with the shifting block of bearing pin, bearing pin being cased with rolling element through rivet, and rolling element is placed in cam path, rolling
Kinetoplast is spherical；Transducer and sensor are connected through different wire groups with circuit board.
When rolling element and the apexes contact in cam path right cam face, transducer does not occur bending and deformation；In the course of work,
When inner ring and outer ring are relatively rotated by roller, camshaft is relatively rotated with transducer and rolling element, and rolling element is in cam path
Inside it is moved to the left, so as to force transducer deformation bending to the left, PZT film bears gradually increased compression；When rolling element with it is convex
During the apexes contact in race left cam face, the deflection at the lamination composite bed of transducer free end two reaches maximum；Hereafter, with
The further rotation of camshaft, rolling element moves right in cam path, and the stress on the deflection and PZT film of transducer is gradually
Reduce, until rolling element and the apexes contact in cam path right cam face, so far complete a complete excitation of transducer；It is above-mentioned
Electric energy is converted mechanical energy into transducer cyclic bending deformation process, the electric energy generated is through the change-over circuit on circuit board
Treatment and supplied sensor, sensor obtains bearing temperature, rotating speed or vibration parameters in real time, then through the transmitting list on circuit board
Member is launched.
In the present invention, when the apexes contact in rolling element and cam path left cam face, the maximum stress in PZT film be less than its allowable value,
Deflection at the lamination composite bed of transducer free end two is less than its allowable value, that is, is less than
Wherein：B=1- α+α β, A=α4(1-β)2-4α3(1-β)+6α2(1- β) -4 α (1- β)+1,α=hm/ H, β=Em/Ep, hmIt is respectively substrate thickness and transducer gross thickness, E with Hm
And EpThe respectively Young's modulus of substrate and PZT film, k31WithRespectively the electromechanical coupling factor of PZT material and pressure allowable should
Power, L is the length of transducer.
Advantage and characteristic：The deformation of transducer bend in one direction, PZT film are subjected only to compression；The deflection of transducer is by cam
Lift determines that maximum stress during different rotating speeds on the maximum deformation quantity and PZT film of transducer is all identical, therefore reliability is high, have
Imitate bandwidth, generating and power supply capacity strong.
