Use of TIMKEN bearing grease maintenance knowledge important role - bearing noise
Use within TIMKEN bearing grease must have antirust effect, rust inhibitor is best can not dissolve in water.
Grease shall have good adhesion, and can form a layer of oil film on the surface of steel, oil in machining will become soft, cause leakage.
During normal operation, oil will by bearing to insert ball bearings.
If the mechanical stability of the oil is insufficient, operation process, the structure of the soap grease causes mechanical disruption of oil was damage, and thus lose lubrication, if the wrong choice grease all preventive measures of TIMKEN bearing is useless, choose a grease, its oil viscosity in working temperature is it is important to be able to provide adequate lubrication effect, viscosity is mainly affected by temperature, it with the temperature rising and falling, is that it increased when the temperature decreases.
Therefore, you must know when working temperature of the oil viscosity.
Machinery manufacturers are usually specified use some grease, however most of the standard grease applicable range is very wide.
In the process of using insert ball bearing, the grease is critical.
If bad grease, used, don't effect not only, and will damage the TIMKEN bearings.
TIMKEN bearing vibration influence on bearing failure is very significant.
For example, peeling, indentation, rust, crack and wear will be reflected in the bearing vibration test so through the use of special bearing vibration measurement device (
Frequency analyzer and vibration meter, etc. )
Can measure the size of the vibration through the frequency distribution can be concluded that the details of the abnormal vibration measured values due to the use of the bearing premise or sensor installation position and different therefore require prior to each machine measurement value judgment dimension after analysis and comparison.
At present, the use of increasingly fine fine bearing equipment, force bearing used in grease must have the following functions: (
No and bearing the same operation life, try to delay the maintenance cycle, shorten downtime, Labour production rate.
Is a dn > under the high speed of 5 x 105 to guaranteeing the motor temperature rise is low, don't jilt oil, thus reducing power consumption, shield machine.
The scalar content restraint is inevitable under the standard, the most earth cutting equipment noise pollution to the situation.
Is doing on the premise of guaranteeing the bearing cryogenic engineering starting and running of spirituality, bearing common problems.
Guaranteeing the output power is minimal.
Tear open come down to the TIMKEN bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container.
Coarse when cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to.
In coarse clean oil, use brush clean up to smooth grease, adhesive, after clean, roughly into fine cleaning).
