Thrust ball bearing TIMKEN bearings lubrication to reduce internal friction and wear, to prevent burning stick, its lubricating effect is as follows.
⑴. Reduce friction and wear.
Constituting the bearing rings, rolling elements, and each contact portion of the retainer to prevent the metal contacts, reducing friction and wear.
⑵. Extend the fatigue life.
Thrust ball bearings rolling fatigue life, in the rotation, the rolling contact surfaces oiled, then extended. Conversely, low viscosity oil, the lubricant film thickness is not good, is shortened.
⑶. Discharge frictional heat, cooling
Circulation to the oil law and other oil discharge occurred by friction heat, or heat coming from the external cooling. Prevent bearing overheating, prevent oil itself aging.
Thrust ball bearing temperature is too high Duanyou include: lubricating oil quality differences requirements or deterioration, lubricating oil viscosity is too high; institutions assembly too tight (not enough open space free); TIMKEN bearing assembly tight; bearing seat on the shaft or shell rolling; load is too large; bearings maintain shelf or body fragmentation.
Thrust ball bearings in the office to allow the operation of a tiny ring children, loud children too large or if there are unusual noise or crash, then the TIMKEN bearing has failed.
1, bearing maintenance, inspection, and the handling of exceptions
For as long as possible in order to maintain good condition TIMKEN bearings original function, to be maintained, inspection, in order to prevent accidents in the first place, to ensure the reliability, improve production and economy. Best maintenance homework premise corresponding mechanical operation scale, on schedule. Including, monitoring operating conditions, add to or replace the lubricant, regular removal of checks.
As a matter of running the test, one-way thrust ball bearing rotary sound, vibration, temperature, lubricant condition and so on.
2, the bearing damage and countermeasures
Usually, if accurate use TIMKEN bearings, fatigue life can be used to achieve so far. But there will be accidental injury prematurely, intolerant in usage. This early damage, and fatigue life relative, called failure or an accident on the quality of the use limit. Multiple causes for installation, use, do not pay attention on the lubrication from outside intrusion of foreign matter, the shaft, the thermal effect of the housing is not sufficient and so on.
