Effect of lubricating grease on bearing noise

The grease used in the bearing must have rust proof effect, and the rust inhibitor is best to dissolve in water. Grease should have good adhesion, and can form a layer of oil film on the surface of steel, grease in mechanical processing will become soft, resulting in leakage. During normal operation, oil will be thrown to the bearing block ball bearing. If the mechanical stability of the oil is not enough, in the process of operation, will make the oil soap structure produces mechanical disintegration, resulting in destruction of fat, resulting in loss of lubrication, if the wrong choice oil bearing all preventive measures in vain, choose a kind of oil, 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, it is necessary to know the base oil viscosity at operating temperature. Machinery manufacturers usually specify the use of a certain kind of grease, but most of the standard grease suitable for a wide range of.
In the process of using spherical ball bearings, grease is the key. If the use of the deterioration of the lubricating grease, not only can not play the role, but also damage to the bearing.
Bearing on the vibration of the bearing failure effect is quite obvious. For example: peeling, indentation, rust, crack and wear are reflected so through the use of bearing vibration measuring device in special bearing vibration detection (frequency analyzer and vibration tester) can measure the size of the vibration can be inferred from the numerical details of the abnormal vibration measured by the use of the premise of bearing or sensor installation location and therefore require prior to each machine to measure the value of the analysis and comparison are determined by frequency distribution scale.
At present, more and more refined by fine bearing equipment, to grease the bearing must have the following functions:
(1) with no bearing the same operating life, as far as possible to delay the maintenance cycle, shorten the down time, forward labor production rate.
(2) under the high speed of DN > 5 * 105 to ensure that the motor temperature rise is low, do not throw oil, thereby reducing power consumption, protection of the motor.
(3) the amount of its pure content under the control of the inevitable standard, the maximum reduction of equipment noise pollution of the situation.
(4) the spirit of bearing starting and running under the condition of super low temperature, the common problem of bearing. Ensure the minimum output power.
Remove bearing cleaning, rough and fine cleaning, placed in a container, put the metal mesh on the bottom, bearing no direct contact with the container. Coarse cleaning, if you rotate the bearings with dirt, can damage the rolling surface of the bearing should be noticed. In the crude oil washing, use brush put to grease, adhesive material, generally clean, to wash.
