Embodiment
Below in conjunction with 1,2 pairs of the utility model of accompanying drawing, be described in detail:
A kind of motor-car traveling portion bearing, gear distress analog platform, it comprises the first direct current adjustable varying-speed motor 1, described the first direct current adjustable varying-speed motor 1 makes input shaft N1(2 by spring coupling 3) with the spline output shaft N2(5 of gear housing 4) be connected, three pinion wheels are installed: gear I 6 input shaft N1(2), gear II 7, gear III 8, output shaft N2(5) two ends are by spring coupling I 9, spring coupling II 10 and magnetic Vib. I 11, magnetic Vib. I 12 is connected, input shaft N1(2) on, be provided with interchangeable bearing holder (housing, cover) 13, output shaft N2(5) the shifting slide gear group I 14 on, in shifting slide gear group II 15, be provided with shift fork 16.
On described interchangeable bearing holder (housing, cover) 13, add fixing bolt and bung flange for radially.
Device experimental principle and the course of work:
The utility model not only can be simulated gear, bearing malfunction separately, can also simulate the combined failure state of bearing-gear simultaneously, makes the fault working condition of closing to reality more of simulation.Its course of work is as follows: the first direct current adjustable varying-speed motor 1 is as power source, by spring coupling 3 and input shaft N1(2) be connected, in gear housing 4, be provided with input shaft N1(2) and output shaft N2(5), input shaft N1(2) three fixed gears of upper installation, output shaft N2(5), in the shifting slide gear group I 14 on, shifting slide gear group II 15, it has five slip locations.
(1) simulate separately gear distress:
As input shaft N1(2) state mediates, now as by output shaft N2(5) shifting slide gear group I 14, the rippling gear of shifting slide gear group II 15 by shift fork 16, regulate and make spot corrosion gear and input shaft N1(2) normal gear engagement, experiment can be simulated the duty (rippling fault, tooth face agglutination fault) of single kind fault gear simultaneously; When by output shaft N2(5) shifting slide gear group I 14, shifting slide gear group II 15 move to left end and make normal gear and input shaft N1(2) normal gear engagement, normal gear engagement is only imitated in experiment; When by output shaft N2(5) shifting slide gear group I 14, rippling gear and the input shaft N1(2 of shifting slide gear group II 15) the engagement of tooth face agglutination gear, experiment can be imitated tooth face agglutination-rippling combined failure and gear tooth breakage fault simultaneously.By that analogy, 6 kinds of different gear distresses can be simulated altogether by this gear set system.
(2) simulate separately bearing fault:
As output shaft N2(5) shifting slide gear group I 14, shifting slide gear group II 15 when high order end or low order end, the output shaft N2(5 of gear case) there is no gear and input shaft N1(2) gear engagement, only now be equivalent to apply power to the transmission shaft of bearing housing 4, can simulate separately the fault of bearing experiment table.On interchangeable bearing holder (housing, cover) 13, can change the bearing (fatigue flake, retainer fracture, outer ring wearing and tearing, inner ring wearing and tearing etc.) of different conditions, can on bearing, add that bolt and bung flange do radially fixing simultaneously, and can radial loaded load.
(3) gear-bearing mixed fault:
Interchangeable bearing holder (housing, cover) 13 is loaded to different bearings (rolling body peels off, retainer ruptures, wear and tear in outer ring, inner ring wearing and tearing etc.), and radially fixing, by output shaft N2(5) shifting slide gear group I 14, shifting slide gear group II 15 move to and input shaft N1(2) gear I 6, gear II 7, gear III 8 while being meshed, now can be with reference to the method for gear distress simulation, simulate the mixed fault of gear-bearing simultaneously, make experimental simulation fault more can reflect the actual condition of production.
The present invention can be used for traveling portion inner teeth roller box vibration monitoring and diagnostic field, can be comprehensive, objective, the resultant fault state of fault (as outer ring fault, inner ring fault, rolling body fault, retainer fault etc.), gear distress (as case crush, gear tooth breakage, rippling etc.) and the bearing-gear of simulating respectively exactly rolling bearing.By the assembled arrangement structure of shift fork inversion mechanism, can also observe the coupling fault signal of two pairs of gears and the change procedure of fault-signal.
Motor driven gear rotate to produce vibration signal as shown in Figure 2, and by acceleration transducer, receive to PC and carry out data acquisition, the PID control system control detent brake condition that is connected with PC by USB interface, PLC can control motor speed, current measurement.
