Technical field
The utility model relates to the speed-reducing clutch technical field, particularly a kind of noise measuring system of speed-reducing clutch.
Background technology
A lot of speed-reducing clutch fault detection methods are arranged at present, roughly can be divided into: vibratory drilling method, noise method, temperature method.Wherein vibratory drilling method is used the most extensively, and it is by being installed in the vibration transducer monitoring speed-reducing clutch vibration signal of speed-reducing clutch seat or casing proper orientation, and this signal is analyzed and handle judge speed-reducing clutch operating mode and fault.Carry out fault detect with vibratory drilling method, can be divided into time detecting method and frequency detecting method.Several detected parameters of present comparative maturity are in the time detecting method: peak value, effective value, peak factor, kurtosis and pulse factor etc.In the frequency analysis method there be representational test item: sync equalizing, cepstrum, adjustable frequency analytic approach, high-frequency resonance analytic approach and short signal processing etc.At present, the speed-reducing clutch fault detection system of domestic and international Development and Production is mostly according to the vibratory drilling method principle design.
The tolerance of vibration can represent that on mathematics state's speed-reducing clutch industry member has been developed acceleration type and velocity profile two big class speed-reducing clutch vibration measurement instruments at the initial stage eighties with speed, acceleration.The velocity profile sensor has covered the rumble spectrum scope of speed-reducing clutch, so use commonplace substantially because its frequency response reaches 15KHz.Accelerometer type of sensor can be greater than 15KHz with regard to itself Hz-KHz, but owing to often will add spring in using and vibration-sensing rod constitutes sensor-based system, its frequency response often is lower than 6KHz, can not cover whole vibration frequencies of speed-reducing clutch, but this sensor is simple, not fragile, use also many in practice.
Mainly there are following some shortcomings at present domestic several speed-reducing clutch vibration measurement instrument that generally uses when detecting noise:
1, a plurality of detection data are finished with many computing machines, can not gather automatically between each computer data.Labor strength is big.An operative employee will test about 1000 speed-reducing clutch under the condition of work at one day 8 hours, a series of activities such as the workman will finish speed-reducing clutch is installed, watch the instruments, listens different sound, sees waveform, dismounting speed-reducing clutch, and require basically in 30 seconds, to finish, labour intensity is very big, easily erroneous judgement.
2, be to listen the mode of different sound to differentiate by the operative employee with earphone to the speed-reducing clutch failure judgment method, mode is backward relatively.It needs to be noted, because labor strength is very big, and overall qualities are uneven, adds the workman and differentiate speed-reducing clutch quality quality by the mode of listening different sound, these factors add up, and can not provide very high assurance to the differentiation of speed-reducing clutch quality quality.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of automatic detection noise, the noise measuring system of the speed-reducing clutch of reporting to the police of being out of order.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of noise measuring system of speed-reducing clutch, comprise main control module, display module, data collecting card, described main control module is connected with data collecting card, and the input end of described data collecting card is connected with washing noise signal collecting unit and dehydration noise signal collecting unit.
Described washing noise signal collecting unit and dehydration noise signal collecting unit all adopt vibration transducer, are lifted on the washing noise and the dehydration noise measuring station top of speed-reducing clutch assembling line end respectively.
Described main control module adopts industrial control computer.

The utility model adopts said structure, have the following advantages: 1, the data of using unified integrated interface display multiple sensor collection down based on the separate unit industrial control computer, and draw the vibration noise oscillogram in real time, and cooperate the running status of each work station point on the indication production line with animation.Aspect man-machine interaction, have certain convenience, aesthetic property; 2, realize the automatic judgement of speed-reducing clutch product quality, will detect with fault diagnosis organically integratedly automatically, improved the intelligent of this detection platform.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a logical organization block diagram of the present utility model;
In Fig. 1,1, the main control module; 2, display; 3, data collecting card; 5, malfunction indicator lamp; 6, big LCD display; 7, dehydration noise signal collecting unit; 8, washing noise signal collecting unit.
Embodiment
A kind of noise measuring system of speed-reducing clutch comprises main control module 1, display 2, data collecting card 3 as shown in Figure 1, and data collecting card 3 is the PCI-1710L data collecting card.Described main control module 1 is connected with data collecting card 3, and the input end of data collecting card 3 is connected with washing noise signal collecting unit 8 and dehydration noise signal collecting unit 7.Washing noise signal collecting unit 8 and dehydration noise signal collecting unit 7 all adopt vibration transducer, are lifted on the washing noise and the dehydration noise measuring station top of speed-reducing clutch assembling line end respectively.Main control module 1 adopts industrial control computer.Display module comprises display 2 and big LCD display 6.The input end of main control module 1 is connected with keyboard load module and bar code scan rifle.Can be by keyboard load module input data.The input end of data collecting card 3 is connected with the PLC controller, with the operation that realizes the speed-reducing clutch production line, stop to cooperate synchronously with speed-reducing clutch braking moment signals collecting.The output terminal of main control module 1 is connected with printer and malfunction indicator lamp 5 respectively.Vibration transducer is transferred to data collecting card 3 after the fault-signal of No. 2 work station points is gathered, and data collecting card is transferred to the main control module with this signal, the main control module with signal Processing after output control fault pilot lamp 5, and show by display module.
Noise measuring comprises washing noise and dehydration noise.Washing noise and dehydration noise all belong to the category of vibration noise, and the detection test of vibration noise can be adopted vibration displacement sensor, vibrating speed sensors, vibration acceleration sensor or noncontact electromagnetic potential displacement sensor to detect vibration noise and require the continuous data of output so that the real-time continuing noise waveform of follow-up output.The vibration displacement sensor construction is simple, and cost is low, but Hz-KHz is narrow, is difficult for detecting the different sound of some high frequency.Vibrating speed sensors, vibration acceleration sensor precision are higher, and Hz-KHz is moderate, but volume is relatively large, and can the output low frequency natural frequency.Noncontact electromagnetic potential displacement sensor measuring accuracy height, Hz-KHz are wide, and be easy for installation with the workpiece noncontact, but the cost height, be subject to electromagnetic interference (EMI), and particularly the degree disturbed of industry spot is bigger.Therefore by the vibration noise test experience, select to detect the preferable relatively sensor of effect, the advantage of the multiresolution analysis of combined with wavelet transformed algorithm detects the different sound in the defective speed-reducing clutch again.
