Description
Technical field
The present invention relates to mechanized equipment key components and parts health status dynamic monitoring fields, more particularly to a kind of to be suitable for rolling
Dynamic bearing tests the spontaneous electrical component of system.
Background technology
Rolling bearing is widely used in the key areas such as aerospace, railway, steamer, heavy duty machine tools, it is as whirler
The key components and parts of tool play the important function of support shafting and passing power.Meanwhile rolling bearing is also that rotating machinery is most thin
A weak ring, according to statistics, the failure 30% of rotating machinery is caused by bearing damage, so the operating status of rolling bearing is just
The performance of whole equipment is often directly affected whether often.Long term state monitoring is of crucial importance to be realized to bearing for this.Bearing intelligence
Energyization, that is, integrated data acquisition becomes a Main way of bearing development with condition monitoring system within the bearing.However
Complication with shafting and Highgrade integration generally require multiple bearings and are assembled, if you need to carry out state to all multiple bearings
Monitoring, often leads to test system power supply and signal line wiring is complicated, and reliability is low, has larger security risk.Meanwhile it is existing
It is having studies have shown that bearing rotary component operating mode is changed it is more sensitive, therefore in traditional base monitored for stationary parts
On plinth, monitoring to bearing rotary component and more and more important is become to the monitoring of bearing whole assembly state.
The energy supply that rotary part tests system is a technological difficulties all the time, is especially worked normally in bearing
Environment in realize energy supply.Bearing is essentially consisted in bearing block, narrow space and environment complexity.More
Automatically supplying for energy may be implemented in ripe electric generator structure, but electric generator structure is complicated, and volume is larger, it is difficult to be integrated into bearing
In the shafting of assembly.Department of mechanical engineering of armored force engineering institute fourth rushes, Zhao Yongdong etc. utilizes electromagnetic coupling wireless power technology,
Torque measurement is realized by contactless inductive power supply technique, but general electromagnetic coupling power supply scheme is due to eddy current effect, it is difficult to
Meet the energy supply in narrow ferromagnetic space, and the primary coil used in its power supply process must use external electricity
Source, and then could realize wireless power, and static test system is also needed to add individual electric energy feed unit.Greatly
Even times ancestor's gold, Zhang Jun et al. of Polytechnics《A kind of experiment for realizing the rotation of power generator Internal and external cycle respectively》Carried side in patent
Two kinds of forms of motion that Internal and external cycle rotates respectively have may be implemented in case, have reached and have carried out principle test and stage die to power generator
The purpose of quasi- test, this is simple in structure, realizes that Internal and external cycle rotates respectively by unilateral bearing, but rolling bearing installation space is extremely
Limited, the program is difficult to be integrated in the Internal and external cycle test system of bearing.The axis of the stone nonyl occasion of Beijing Institute of Technology, Sui Li et al.
The relative motion of stator and rotor in generator is realized using wind energy and then produce electricl energy to magnetic field magnetoelectricity type micro generator patent,
However the structure only realizes that rotating coil generates electricity, and is drawn electric energy with ball by connecting shaft, since the mechanical parts such as ball are deposited
So that the structure size is larger, it is difficult to be integrated in the narrow installation space of bearing, and be not carried out to bearing stationary part
Part tests system and rotary part test system capacity synchronizes supply.Opto-electronic conversion energy supply may be implemented to rotary part
The energy supply of test system, it, come driving energy receiving terminal, and then makes luminous energy be converted into electric energy to expire by strong illumination
Pedal system energy requirement, but for the working environment of bearing, this energy supply scheme is just difficult to deal with, and carries greasy dirt and mist of oil
Environment be easy to the propagation of obstruction light, deposition of the greasy dirt at energy acceptance end be also it is unavoidable, and complicated, it is difficult
With in the actual condition applied to rolling bearing.
