Background technique
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 oscillating 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 faut detection 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, crest factor, kurtosis and pulse factor etc.In the frequency analysis method there be representational test item: sync equalizing, cepstrum, adjustable frequency analytic method, high-frequency resonance analytic method 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 industrial quarters 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 sensed 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:
1, a plurality of detection data are finished with many computers, can not gather automatically between each computer data.Labor strength is big.An operator will test 1000 speed-reducing clutchs under the operating conditions at one day 8 hours, the workman will finish material loading, watches the instruments, listen different sound, see a series of activities such as waveform, and require basically in 30 seconds, to finish, labor intensity is very big, easily erroneous judgement.
2, be to listen the mode of different sound to differentiate by the operator 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.

In Fig. 1,1, the main control module; 2, display device; 3, data collecting card; 4, braking moment signal gathering unit; 5, opening force signal gathering unit; 6, washing noise signal collecting unit; 7, dehydration noise signal collecting unit; 8, brake lag signal gathering unit; 9, big LCD display.
Embodiment
A kind of online system failure diagnosis of speed-reducing clutch as shown in Figure 1, comprise main control module 1, display modular, data collecting card 3, main control module 1 is connected with data collecting card 3, and the input end of described data collecting card 3 is connected with braking moment signal gathering unit 4, opening force signal gathering unit 5, washing noise signal collecting unit 6, dehydration noise signal collecting unit 7 and brake lag signal gathering unit 8 respectively.This system comprises that the first detection station, second of the end that is arranged on production line detects station and the 3rd and detects station.Braking moment signal gathering unit 4 and opening force signal gathering unit 5 adopt load sensor respectively, and described load sensor is installed in first respectively and detects on station and the 3rd detection station.Washing noise signal collecting unit 6 and dehydration noise signal collecting unit 7 adopt vibration transducer respectively, and described vibration transducer is installed in second respectively and detects on station and the 3rd detection station.Brake lag signal gathering unit 8 adopts Hall transducer, and described Hall transducer is installed in the 3rd and detects on the station.Main control module 1 adopts industrial control computer.Display modular comprises display device 2 and big LCD display 9.The input end of main control module 1 is connected with keyboard load module and bar code scan rifle.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 the speed-reducing clutch signals collecting.The output terminal of main control module 1 is connected with printer and fault indicating lamp respectively.
To braking moment with open measurement of force, can adopt with a kind of load sensor, different is: the data of " power " that will collect multiply by the arm of force on software is handled be exactly braking moment, and opening force does not need to take advantage of the arm of force.It is a big event of speed-reducing clutch performance test that braking moment detects test, test requirements document speed-reducing clutch once in the process of combination to the variation of braking moment sample, filtering, record, calculating.Moment equals power and multiply by the arm of force, by load sensor the power that records be multiply by the braking moment parameter that the arm of force just can obtain the detection that requires.Because the principle of measurement of load sensor is to use the Wheatstone bridge method, the output of sensor is not stable direct current, but the superposed signal of direct current and white Gaussian noise.The size and the power of direct current are linear.Therefore at first will adopt the low noise instrument amplifier to the amplification of this signal, one group of data of continuous acquisition are made Shelving with the mode of statistical signal processing more then, obtain the DC level value.
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 intended of vibration noise adopts vibration displacement sensor, vibrating speed sensors, vibration acceleration sensor or non-contact electromagnetic potential displacement sensor to detect vibration noise and requires 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.Non-contact electromagnetic potential displacement sensor measuring accuracy height, Hz-KHz are wide, and be easy for installation with the workpiece non-contact, but the cost height, be subject to electromagnetic interference, 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.
This system finally selects for use vibrating speed sensors to detect vibration noise, can follow intrinsic low frequency signal at the output of vibrating speed sensors, in the design amplification circuit, has added that rearmounted high-pass filter solves.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
