Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, interior dress IC acceleration transducer comprises piezoelectric acceleration sensor and charge amplifier, by constant current source power supply, during the acting force of pressing when piezoelectric crystal detects/drawing, its output charge signal becomes after amplifying ± AC signal in the 5v scope, directly transport in the data collecting card of computing machine and carry out the A/D conversion, form storage with the series data of constant duration, as filtering, correlation analysis, the foundation of digital signal processing such as power spectrumanalysis, frequency-domain waveform after the analyzing and processing and quality discrimination result are shown on display, and to the abnormal products sound and light alarm.
In principal and subordinate's gear pairing runing condensation procedure, the impact shock occurrence frequency that causes owing to the flank of tooth, installation question is the following series of discrete value of meshing frequency f, and by the number of teeth decision of master and slave gear, the impact shock amplitude then reflects the size of flank engagement error.
Interior dress IC acceleration transducer is separately fixed on the gear pairing running-in platform, and the impact shock that takes place in the runing condensation procedure can react on the running-in platform, and the structure vibration signals of measurement running-in platform relevant position can be differentiated the meshing quality between the master and slave gear.
The function of running-in platform self vibration noise is at first filtered in the utility model setting by empty running-in.The utility model is provided with school zero switch, when it is the ON state, the calibration pilot lamp is bright, because correlativity before and after the vibration interference signal of environment does not have on time series, its autocorrelation function is zero in theory, and slightly vibration can be considered linear system, is suitable for superposition principle, utilize relevant function method, the power spectrum that institute's vibration measuring is moved signal is stored as reference signal.Frequency-amplitude that mesh vibration acceleration signal power spectrum also is set simultaneously is interval as differentiating threshold values automatically.
Then principal and subordinate's gear is installed, start testing button, by measuring the acceleration of driving gear shaft landing and two passages of pedestal simultaneously, deduct the influence of the fixing vibration of structure with the frequency domain stacking method, remove the interference of environment vibration with self-adaptation phase elimination, obtain deriving from gear meshing and impact the vibration signal that causes, as the foundation of differentiating the meshing quality between principal and subordinate's tooth.When the peak value of vibration signal power spectrum when threshold line is following, it is qualified that qualified pilot lamp turns green expression, the green light of audible-visual annunciator is bright simultaneously; When the peak value of power spectrum when threshold line is above, the expression that reddens of unusual pilot lamp is unusual, the red light of audible-visual annunciator is bright simultaneously, hummer rings.
