In using the TIMKEN bearing, it can be said that vibrations and effects of temperature on the bearing is very large, we first look at the effect of vibration on bearing bearings.
Vibration damage to the bearings can be said to be quite sensitive to indentation, rust, cracks, spalling, and wear are reflected in the measurement of bearing vibration. So, by using a special measuring bearing vibration (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured the numerical bearing conditions of use or different sensors such as installation location and therefore require prior to analysis and comparison of measurement values of each machine are determined criteria.
High temperature often indicates that the bearing is in exceptions. High temperatures may also be harmful to the bearing lubricant. Sometimes bearing overheating can blame on the bearing lubricant. If bearings in more than 125 ℃ temperature long-term continuous transfers reduce bearing life. Cause of the high temperature bearings include: insufficient lubrication or excessive lubrication, lubricant. Contains impurities, excessive load, bearing loss rings, insufficient clearances, and oil have high friction and so on.
Therefore continuity bearing temperature monitoring is necessary, whether measured or other important parts of the bearing itself. If operating conditions do not change case, any temperature changes may have occurred at fault.
There are many reasons for early damage of TIMKEN bearings resulting, sometimes likely to be is reason. If the bearing selection is correct installation correctly in place, lubrication and lubricant selection is correct, keep maintenance and preventive measures, the bearing is working for a long time.
1. improper Assembly
Installation using brute force, are the main cause of deformation. Installation is not in place, is a defect of reason.
Recommendation: select the appropriate bearing installation tool or professional, installed using special instruments and testing.
2. pollution damage
Pollution can also cause premature damage of TIMKEN bearings, pollution refers to water, dust, scrap metal into the bearing. May cause the bearings rusted, face wear, scratches and dents.
Recommendation: periodically check the seals, bearings to be used for cleaning; enhanced TIMKEN bearing sealing device.
3. poor lubrication
No lubrication or lubricant in a timely manner; lubricant or lubricant does not raise in place; selection of lubricants or lubricant improper; incorrect lubrication method, and so on, leads to component abrasion or TIMKEN bearing deformation.
Recommendation: choose the right lubricant or lubricant, notation uses the correct lubrication, regular replenishment of the lubricant.
4. current and eccentric
Bearings powered may cause occur when you rotate notch or nicks, bearing at rest, improperly grounded electrical operation will cause a minor burn, eccentric or load operation may cause geometric stress concentration, or peeling surface.
Recommendation: for parts before welding bearing through appropriate grounding connection to reduce or prevent current through bearing, precise machining TIMKEN bearing seats and abutments.
