Inch Series Tapered Roller Bearing

Inch Series Tapered Roller Bearing
ISUTAMI tapered roller bearings inch Series belong to the separated precision bearings, its use should be accordingly serious, if not properly used will be damaged in advance.Tapered roller bearing inner ring and outer ring raceway surface, because the rolling body is rolling contact, so the running track is dark surface, the running track is attached to the raceway surface is not very, thus change can be known the load premise, so the environment is being removed bearing, bearing seal what type.If you observe the running track of raceway surface carefully, you will get radial load, large axial load, torque load, or no extreme rigidity inequality on the bearing box.When removing the conical roller bearing for inspection, confirm the amount of residual lubricant and sample the lubricant before cleaning the bearing.The cleaning of conical roller bearing is divided into rough cleaning and fine cleaning, and a metal net frame can be placed at the bottom of the container.Coarse washing, in the oil with a brush to remove grease or adhesion.At this point, if the bearing is rotated in oil, pay attention to the rolling surface will be damaged due to foreign bodies.Fine washing, in the oil slowly rotating tapered roller bearings, must be carefully carried out.The cleaner that USES normally is neuteral do not contain water diesel oil or kerosene, also use lukewarm sex lye to wait sometimes according to need.Always filter to keep it clean, no matter what cleaning agent you use.After cleaning conical roller bearings coated with anti-rust oil or anti-rust grease.

Inch Series Tapered Roller Bearing Features

After the conical roller bearing moves for a period of time, vibration and noise maintain a certain level, the frequency spectrum is very simple, only one or two times the frequency, rarely appear more than three times the frequency spectrum, conical roller bearing state is very stable, into a stable working period.In the later period after continuous operation, bearing vibration and noise began to increase, sometimes abnormal sound appeared, but the change of vibration increased slowly, at this time, the taper roller bearing began to suddenly reach a certain value, at this time the bearing is shown as the initial failure.It is required to monitor the bearing closely and pay close attention to its changes.Since then tapered roller bearing and started falling fast, and close to normal, and significant increase in vibration and noise, it began to accelerate, increasing when the vibration more than standard, its bearing also began to increase rapidly, when more than vibration standard, taper roller bearing fault, has entered the late need to timely maintenance equipment, replace the bearing.Tapered roller bearings show late failure characteristics to serious failure, most of the time does not exceed one week, the larger the capacity of the equipment, the faster the speed, the shorter the interval time.Therefore, in the actual fault diagnosis of tapered roller bearing, once the late fault characteristics are found, it should be determined that there is a fault in the bearing, and the maintenance should be arranged as soon as possible.Lubrication has an important influence on the fatigue life, friction, wear, temperature rise and vibration of tapered roller bearing. Without normal lubrication, the bearing cannot work.Analysis of the reasons for bearing damage shows that most of the bearing damage is related to poor lubrication.Therefore, good lubrication of the bearing is an effective measure to reduce the friction and wear of the bearing.In addition, bearing lubrication and heat dissipation, rust prevention, sealing, impact mitigation and other functions.
