The important role of the slewing ring bearings noise and maintenance using grease

Used in  slewing ring bearings  grease must have antirust effect, anti rust agent preferably insoluble in water. Grease has good adhesion, and can form a layer of oil film on the steel surface, the oil will become soft in the mechanical machining, resulting in leakage. During normal operation, the fat by Deep groove ball bearing seat to swing block ball bearings. If the grease is not enough mechanical stability, operation process, will make the oil soap structure produces mechanical disintegration, resulting in destruction of fat, resulting in loss of lubrication, if the wrong choice grease all prevention bearing measures in vain, select a grease base oil viscosity, it is able to provide sufficient lubrication effect at the working temperature is very important, viscosity is mainly affected by temperature, it decreased with the increase of temperature, when the temperature drop is that it increased. Therefore, must know the base oil viscosity at operating temperature. Machinery manufacturers are typically specified using some kind of grease, but the scope of most of the standard grease is very wide.
In the process of using spherical ball bearing, grease is the key. If, the use of grease deterioration, can not play a role, and will damage the bearing.
Bearing vibration of bearing failure effect is very significant. For example: peeling, indentation, rust, crack, wear will be reflected so the bearing vibration measuring device special in the bearing vibration detection (frequency analyzer and vibration meter) measure the magnitude of vibration can be inferred from the numerical details of abnormal vibration the measured by bearing the premise or sensor installation location and different therefore require prior to each machine measurements were compared to determine the scale by frequency distribution.
