Abstract
The utility model provides a gear noise detector which can not only finish quantitative detection of noise generated by a tested gear when being meshed with a standard gear, but also can check whether the tested gear is qualified or not by vibration detection means and find out the positions of burrs on the tested gear. The gear noise detector is characterized in that a transmitting magnetic steel is arranged at the tail ends of spindles of a shaft I and a shaft II respectively, a Hall sensor is arranged on box bodies of the shaft I and the shaft II respectively, an acceleration sensor is arranged at the tail shelves of the shaft I and the shaft II respectively, a microphone is arranged in the meshing area of the tested gear and the standard gear.
Description
Technical field
The utility model relates to a kind of gear noise testing machine, is applied to the vibration and the noise situations of gear manufacturing fast quantification, the engagement of fixed point detection of gear.
Background technology
At present, the domestic gear noise testing machine that generally uses, the noise that produces in the time of can only be to gearing mesh carries out qualitative detection, can not carry out detection by quantitative, and be subjected to artificial factor very big.Its detection method commonly used is: a detected gear clamping is meshed on gear noise testing machine and with master gear, selected suitable rotating speed, start lathe, detected gear is rotated under the drive of master gear, at this moment, operating personnel can only go to listen tested gear and master gear to mesh the noise situations that is produced with ear, judge by rule of thumb whether detected gear is qualified, it is very big influenced by human factor, and this kind gear noise testing machine to around neighbourhood noise have relatively high expectations, otherwise will influence operating personnel's judged result.
Summary of the invention
The purpose of this utility model then is the problem that exists at above-mentioned prior art, a kind of gear noise testing machine is provided, the detection by quantitative of the noise that it is produced in the time of can not only finishing detected gear and master gear engagement, and can also determine whether detected gear is qualified, and find out the spur location on the detected gear with the method that detects vibration.
The purpose of this utility model is achieved in that
Afterbody at I axle main shaft and II axle main shaft is respectively adorned a sender magnet steel, on I axle main shaft casing and II axle main shaft casing, a Hall element is installed respectively, adjust between Hall element and the sender magnet steel near distance, make the sender magnet steel with one week of main axis rotation, the Hall element induced signal once and by electric wire is sent to instrument, the phase place that will guarantee simultaneously to post a letter is consistent with the angle on the main shaft, so that accurately judge the spur location on the detected gear.On I axle tailstock and II axle tailstock, an acceleration transducer is installed respectively, when main axis rotation, acceleration transducer collects the vibration signal of I axle and II axle and is sent to separately charge amplifier respectively by electric wire and carries out filtering, amplifies and be sent to instrument again, instrument is showing the vibrational waveform of each respectively and is showing the amplitude position of (promptly defective) point on axle that exceed standard after treatment on the display.In the zone that tested gear is meshed with master gear a microphone is installed, when tested gear and master gear engagement rotation, microphone with the noise signal of picking up directly send into handle in the instrument after, instrument demonstrates spectral characteristics of noise and noise decibel value, in view of the above, can determine whether tested gear is qualified.
Advantage of the present utility model:
The utility model is owing to adopt such scheme, the detection by quantitative of the noise that is produced in the time of can not only finishing the engagement of detected gear and master gear, and can also determine whether detected gear is qualified, and find out the spur location on the detected gear with the method that detects vibration.In addition, the method for employing detection vibration need not require the installation environment of gear noise testing machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Among the figure 1, I axle charge amplifier 2, II axle charge amplifier 3, I axle Hall element 4, I axle sender magnet steel 5, I axle main shaft 6, master gear 7, microphone 8, I axle tailstock thimble 9, I axle acceleration sensor 10, II axle acceleration sensor 11, II axle tailstock thimble 12, tested gear 13, II axle main shaft 14, II axle sender magnet steel 15, II axle Hall element 16, instrument
When carrying out vibration detection, at first read the signal detection axle rotating speed and the axle original position of I axle sender magnet steel 4 and II axle sender magnet steel 14 respectively by I axle Hall element 3 and II axle Hall element 15, the vibration signal that I axle acceleration sensor 9 and II axle acceleration sensor 10 obtain respectively is through I axle charge amplifier 1 and 2 filtering of II axle charge amplifier, after the amplification, send into instrument respectively, by the microprocessing systems in the instrument data that collect are preserved with superthreshold and to judge, and calculating superthreshold position, after test is finished, whether qualified instrument display can show the vibrational waveform and the superthreshold position of I axle and II axle respectively, and provide tested gear 12 conclusion.For underproof tested gear 12, the angle scale on detected superthreshold position and the II axle main shaft 13 is one to one, and the spur location on the tested like this gear 12 can be found out.
When carrying out walkaway, microphone 7 is directly sent into the noise signal of picking up in the instrument 16 and is handled, and after effective value and decibel value calculated, instrument display demonstrated the noise decibel value of spectral characteristics of noise, in view of the above, can determine whether tested gear 12 is qualified.
Claims (2)
1, a kind of gear noise testing machine, it is characterized in that respectively adorning a sender magnet steel at the afterbody of I axle main shaft and II axle main shaft, on I axle main shaft casing and II axle main shaft casing, a Hall element is installed respectively, on I axle tailstock and II axle tailstock, an acceleration transducer is installed respectively, a microphone is installed in the zone that tested gear is meshed with master gear.
2, gear noise testing machine according to claim 1 is characterized in that master gear is clamped between I axle main shaft and the I axle tailstock thimble, and tested gear is clamped between II axle main shaft and the II axle tailstock thimble.
