The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Shown in Fig. 1, Fig. 2, in bearing rolling play operation, back-up roll 1 and 8 synergy of servo loading roll clamp and drive measured bearing 2, and the control by rolling play operation control system applies with operating pressure measured bearing 2 in process.When servo loading roll 8 back-up rolls 1 accept only to reach clamp axis the pressure contact measured bearing 1 that is bordering on " no-load ", system enters preparation, running-in, test phase.On measured bearing 2, by shaft coupling 7, connect a dynamic force moment sensor 3, the bearing moment signal recording on it is transferred to signal handling equipment 9, signal handling equipment 9 is used for collecting, process, show and recording the torque signals of this measured bearing 2, and this signal is transferred to rolling play operation control system 4.Direct current generator 5 is as the drive source of measuring system, for system provides power.The voltage swing applying on direct current generator 5 is controlled according to the detection data of transmission on signal handling equipment 9 by rolling play operation control system 4, and then controls the rotating speed size of direct current generator 5.In the course of the work, the size that servo loading roll 8 is applied to the pressure on measured bearing 2 is also to be controlled according to the detection data of transmission on signal handling equipment 9 by rolling play operation control system 4 with size back-up roll 1 and rotating speed.Between direct current generator 5 and dynamic force moment sensor 3, by shaft coupling 7, connect a unilateral bearing 6.
Figure 3 shows that the fundamental diagram of native system, the coordinate curve in Fig. 3 represents nip pressure curve map in rolling play operation, roll rotational speed curve map, measured bearing inner ring speed curves figure, direct current generator voltage and speed curves figure, measured bearing M curve figure from the top down successively.In figure:

In conjunction with Fig. 3, provide in detail systems approach provided by the present invention, comprise that step is as follows:
1) preparatory stage a:
Rolling play is initial, and roll accepts only to reach clamp axis the P that is bordering on " no-load "
0the processed bearing products of pressure contact, owing to now there is no play between this product Internal and external cycle, inner ring with outer ring with n
1speed synchronous rotary.Meanwhile, direct current generator is with lower than n
1speed (n
2) rotating Vortex.Due to the effect of unilateral bearing, between motor and test product, move non-interference.Now, torque sensor measurement is output as zero.
2) rolling play stage b:
● the rolling starting stage
Roll is forced into operating pressure P gradually
1in processed bearing products, operation enters the rolling play stage.Direct current generator is applied to the triangular wave superimposed voltage that frequency is about 5Hz simultaneously, order about direct current generator raising speed, to n
1moment more than critical speed, unilateral bearing works, and makes direct current generator as system drive mechanism, and measured bearing moment is loading moment.As torque sensor now records measured bearing moment, much larger than setting protection value T
2or the no-load starting moment of friction higher limit T of product requirement
0above, direct current generator auxiliary voltage is fallen, and the direct current generator speed of being fallen is back in n
2(< n
1).
● rolling play working stage
In later stage rolling starting stage, as record the moment of bearing products lower than the setting moment higher limit T of measured bearing
0time, system enters rolling play working stage.Now, the superimposed voltage that puts on direct current generator continues to rise to V
3, DC motor speed further rises to n immediately
3(n
3> n1).Be subject to unilateral bearing effect, dynamic force moment sensor is at direct current generator n
3rotating speed drives, measured bearing moment is load, and (inner ring of measured bearing is to surpass outer ring rotation speed n
1n
3rotating speed rotation), under acting in conjunction, gather the moment numerical value of measured bearing, and provide moment variations curve by computer system.
3) running-in stage c
When measured bearing moment values drops to setting value T
3time, rolling mill pressure roller earth pressure release is to " no-load " (minute loadings clamping) pressure P
0, and under nearly " zero " pressure state, processed bearing inner race is under direct current generator driving, with higher than its outer ring rotation speed n
1n
3continuous running a period of time, play the running-in effect of bearing.
4) test phase d
After running-in finishes, direct current generator and roll stop operating simultaneously, but roll is still with " no-load " (minute loadings clamping) pressure P
0clamping measured bearing.System enters the product test stage: direct current generator has started driving effect, and torque sensor is measured measured bearing no-load starting moment.Motor continues rotation and measures bearing slip moment, and computer shows whole moment variations curve, is completed, and servo loading roll departs from product, and direct current generator quits work, roll stall, and whole rolling play operation finishes.
The online instant measurement and control system of above-mentioned self-lubricating knuckle bearing moment disclosed in this invention and method, utilize the convertible properties of the input of dynamic force moment sensor, output shaft definition, solve in rolling process, by rolling initial stage Internal and external cycle, the moment during without play state detects drive source and transfers the transfer problem that detects load source when later stage Internal and external cycle has play state to bearing.Adopted unilateral bearing, realize " disengagement " of rolling initial stage direct current generator and dynamic force moment sensor, and in follow-up rolling process, when system is surveyed processed bearing moment, direct current generator becomes detection drive source, and by transmission of power the function to dynamic force moment sensor power shaft.System has been introduced Internal and external cycle " running-in " technique of processed bearing " no-load " in rolling process (under minute loadings clamping).Rolling latter stage, system is carried out product by the online startup of inactive state, detects the slip moment in no-load starting moment and product inner ring rotation process, differentiates the dynamic mass of product comprehensively.
