1. The use of magnetic plug on the cylindrical roller bearings for monitoring requirements
(1) Magnetic plugs are only suitable for critical main bearings that are lubricated with oil and return oil through dedicated piping.
(2) magnetic plug to be installed in the vicinity of the main bearing to be monitored, in the main return channel, the middle of the filter, oil pump and other hydraulic parts of the barrier.
(3) In order to improve the monitoring efficiency, can produce a return oil import and export of rotary oil conservator. The oil reservoir should be made into an inverted truncated cone shape, and the magnetic plug should be installed at the bottom of the oil reservoir. Oil inlet into the oil tank to a certain angle, so that oil can be tangential to enter. This is conducive to wear abrasive and rotary lubricant separation and precipitation in the bottom, through the hole into the magnetic plug, the adsorption in the magnetic head.
2. Morphological characteristics of abrasive grains under normal conditions
Cylindrical roller bearings in the run-in period and normal operation period, the resulting size of the debris is generally 0.01 ~ 0.015mm, and mixed with some metal powder. The number of abrasive debris generated during the running-in period of the new bearing is more than the normal running period, and the number of the abrasive debris and the metal powder after the normal operation period is reduced remarkably. Abrasive debris under the microscope showed a thin and short shape, with irregular cross-section.
3. Morphological characteristics of abrasive wear particles
The main failure mode of cylindrical roller bearings is fatigue pitting. Rolling fatigue, peeling off the formation of abrasive debris size is generally 0.025 ~ 0.05mm. Sometimes there are larger pieces of debris, and mixed with some metal powder. The ball bearing abrasive grain fragments generally exhibit a generally circular, radially separated form of rose petals; the abrasive fragments of the raceway exhibit a generally circular surface crushing form; the roller bearing abrasive grains Generally exhibiting a curled rectangular form with a length equal to 2 to 3 times the width; the abrasive grains of the raceway generally exhibit an irregular rectangle.
