How do I remove spherical roller bearings?
Open the packing of spherical roller bearings.Lubricating oil lubrication, general also do not have to clean, but, with the instrument or high-speed bearings, to clean with clean oil, remove coated on the bearing antirust agent.General grease lubrication, do not clean, directly filled with grease.
Furthermore, bearings sealed in grease can be used directly without cleaning.Remove the antirust agent of the spherical roller bearings, easy to rust, so can not be placed regardless.When installing to the housing, there are generally many clearance fits, and the outer ring has interference, which is usually pressed in by a press, or there is also a cold-shrink fit method for installation after cooling.
When dry ice is used as coolant and cold shrinkage is used for installation, moisture in the air will condense on the surface of the spherical roller bearings.Therefore, appropriate anti-rust measures are needed.
After continuous operation and entering the later period of use, the vibration and noise of the spherical roller bearings begin to increase, sometimes abnormal sound occurs, but the change of vibration increase is relatively slow. At this time, the bearing kurtosis value suddenly reaches a certain value.We believe that the bearing at this point is the performance of the initial failure.
At this time, it is required to the spherical roller bearings for close monitoring, pay close attention to its changes.Since then, bearing kurtosis value began falling fast, and is close to normal, and significant increase in vibration and noise, it began to accelerate, increasing when the vibration more than standard, spherical roller bearings kurtosis value also began to increase rapidly, when more than vibration standard, and kurtosis value is more than normal, we think the bearing fault has entered the late production, should be timely maintenance equipment, replace the bearing.
