1, INA remove remove interference fit of the outer ring of bearing outer ring, beforehand in setting several outer shell on the circumference of a circle of extrusion screw with screws, one side equal to tighten the screw, remove.
The screw hole cover usual blind plug, tapered roller type INA bearing separation of INA bearings, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly.
2, INA bearings cylindrical hole remove the inner ring of the remove of INA bearings, can use simple mechanical pull out the latest pressure.
At this time, must pay attention to the inner ring under the pulling force.
Large INA bearing inner ring remove oil pressure method is used.
By setting on the axis of hydraulic oil hole, in order to make easy to pull out.
Width of INA bearings, oil pressure method and drawing fixture and disassembly operations.
NU, NJ cylindrical roller INA bearing inner ring remove can take advantage of the induction heating method.
In a short time heating the local, make the inner ring expansion after drawing method.
3, remove the disassembly of INA bearings taper hole in the bearing is small, with tight sleeves INA bearings, with fastening on the shaft gear support inner ring, the nut back a few times, use block with a hammer beating the disassembly.
Large bearing, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion, remove the INA bearing method.
Operation, the possibility of INA bearings suddenly emerge, it is best to nut used as gear block as well.
If INA bearings should be hot concrete judgment method, namely the INA bearings have make full use of the near destruction of specific judgment method is as follows: 1)
Using INA bearing working condition monitoring instrument using SPM or I - such as iron spectrometer
ID吗?
Type 1 INA bearing working condition monitoring instrument to determine the working status and decision INA bearings when INA bearings shall be repair service, this is the most convenient and reliable method.
For example, when using the HD?
Type 1 instrument, when a pointer by warning area close to the danger zone, and after the measures such as to improve the lubrication pointer has not returned, can determine the INA bearing is itself, can take at this time has not yet come into the danger zone, the INA bearing repair service.
Exactly how far away from the danger area began to repair, can be adjusted by the experience.
Use of such instruments, can make full use of INA bearings working potential, and in a timely manner will be INA bearing repair service, and can avoid failure, is safe and economic.
2)
Using simple tools to monitor in does not have the occasion of the instrument, the operator can hold or wrench tools such as conflict of round the closest INA bearing machine shell parts, ashamed of tools to monitor the ear by the tool to the sound of INA bearings operation, using a stethoscope modification can also, of course.
The normal working of INA bearings should be uniform, smooth, not harsh voice instead of the normal working of INA bearings has a wide variety of intermittent, impact or harsh voice.
First have to get used to the normal working of bearing ring, and then you can grasp the judgment is not normal working of INA bearings, and then through the accumulation of practical experience, and further can analyze what kind of abnormal sound corresponds to what kind of INA bearings is not normal.
INA bearing abnormal sound a lot of categories, it is difficult to talk, mainly by experience accumulated.
