Background technology
Bearing is the core component of rotating machinery, and can its running status directly influence plant equipment and stably move.According to statistics, the fault of rotating machinery has 30% owing to bearing fault causes.On the other hand, the discreteness in serviceable life of bearing is very big, and some bearing in use reaches far away and just breaks down designed life, and it is still intact after designed life that some bearing reaches.Therefore, adopt traditional periodic maintenance method can not guarantee the bearing reliability of operation, the ruuning situation of bearing is monitored main significance.During the monitoring bearing running status, most common signal is bearing vibration and temperature signal.
Nowadays, measure the technology widespread use of bearing temperature and vibration signal, typical as electric main shaft is concentrated and has been equipped with a plurality of sensors, vibration transducer and temperature sensor are installed in the circumferential slot of leaving on the rack sleeve, can close-in measurement main shaft bearing vibration signal and the real-time cold oil temperature signal of monitoring main shaft bearing.If in the plant equipment design phase, just consider measuring method, the solution that obtains easily to bearing vibration and temperature signal.But in the practical application, after plant equipment puts into operation often, the measurement demand to bearing temperature and vibration signal has been proposed.Under this situation, face following problem usually: the measurement mechanism installation site tends to be restricted, and must carry out bigger change to plant equipment, and difficulty is big, the cost height; Measure the bearing of different plant equipment, the length that probe need go deep into is often different, measures the bearing vibration signal of different frequency range, and the snap-in force that need apply is also different, and existing apparatus is difficult to regulate snap-in force and probe built-in length, and the device versatility is relatively poor; The dismounting inconvenience is not suitable for the situation that needs frequent dismounting measurement mechanism.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of measurement mechanism that is used to measure bearing temperature and vibration signal, can overcome existing device plant equipment is changed greatly, probe built-in length and snap-in force are adjusted difficulty, the problem of dismounting inconvenience.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of measurement mechanism that is used to measure bearing temperature and vibration signal, comprise the vibration transducer 1 that is connected with vibration-sensing rod 2 one ends, the embedded platinum resistance thermometer sensor, 14 of the other end of vibration-sensing rod 2 in addition, outer surface at vibration-sensing rod 2 is provided with the snap-in force adjusting gear, on the snap-in force adjusting gear clamping device is set.
The outside surface of described vibration-sensing rod 2 is with and compresses end cap 5, the bottom that compresses end cap 5 snaps in the top of outer sleeve 6 of the outside surface that is enclosed within vibration-sensing rod 2 of below, the bottom of this outer sleeve 6 is an end cover 13, and the self sealss end cap is more than 13, be followed successively by the balancing spring 12 that links to each other in twos from bottom to top in outer sleeve 6 inside, include the set nut 11 of the locking collar 10, with suitable clamping screw 9 and the holddown spring 8 of set nut 11, the top of holddown spring 8 links to each other with the bottom that compresses end cap 5, the described end cap 5 that compresses, outer sleeve 6, end cover 13, balancing spring 12, include the set nut 11 of the locking collar 10, clamping screw 9 and the holddown spring 8 suitable with set nut 11 constitute described snap-in force adjusting gear.
Described outer sleeve 6 outside surfaces are with the holing clip 7 that has locking pin 17, and the off-centre operation handle 16 suitable with locking pin 17 is connected with locking pin 17 by bearing pin 18, and described holing clip 7 that has a locking pin 17 and off-centre operation handle 16 thereof and bearing pin 18 constitute described clamping device.
The present invention can overcome existing device plant equipment is changed greatly, and probe built-in length and snap-in force are adjusted difficulty, the problem of dismounting inconvenience.
