Check in operation project TIMKEN bearings of lubrication of rolling sound, vibration, temperature, status, circumstances are as follows:
, TIMKEN bearings of rolling sound measured sound on sound of rolling bearings in operation size, and sound checks, bearings, even with minor injuries such as split, also is making an abnormal sound and irregular sound, using the acoustic measurement can tell.
Second, the TIMKEN bearing vibration damage to the bearing is very sensitive, such as spalling, indentation, rust, cracks, 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 value for TIMKEN bearings use conditions or different sensors such as installation location and therefore require prior to analysis and comparison of measurement values of each machine are determined criteria.
Third, the TIMKEN bearing temperature, General bearing outside of room temperature can be speculated that, if the uses of oil hole can directly measure the temperature of bearing outer ring, the more appropriate. Usually, temperature of the bearings as the run began to rise slowly, 1-2 hours later to reach a steady state. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load to another. If lubricated, install appropriate, TIMKEN bearing temperature quick rise, abnormal high temperature occurs, in which case you must stop, take the necessary preventive measures.
Four, lubrication
(A) the TIMKEN bearing lubrication of lubrication on the fatigue life of rolling bearings and friction, abrasion, temperature, vibration, and so has important implications, without normal lubrication, the bearings will not work. Analyse the causes of TIMKEN bearing damage showed that around 40% TIMKEN bearing damage related to poor lubrication. Therefore, good lubrication of the bearing is the effective measure to reduce bearing friction and wear.
(B) comparison between grease lubrication and oil lubrication of the TIMKEN bearing's lubrication method is generally divided into two grease lubrication and oil lubrication. TIMKEN bearing functions into full play, it is important is based on the use and purpose of use cut, using lubrication method.
(C) grease lubrication grease consists of base oils, thickeners and additives lubricants. When you choose, you should choose the run oil is ideal for TIMKEN bearings using criteria, due to a different trademark, there will also be a lot of differences in performance, at the selected time, attention must be paid.
(D) when you choose to work in accordance with temperature selection of grease grease, key indicators should be dropping point, oxidation stability and low temperature performance, generally used to evaluate high-temperature performance drops, TIMKEN bearing the actual temperature should be below the drop point ℃ 10-20. Use of synthetic grease temperature should be below the drop point ℃ 20-30.
(E) under oil lubrication in high speed, high temperature conditions, lubrication oil-grease lubrication is not adapted to the available. Through a cycle of lubricant, you can take a lot of heat. Viscosity is an important lubricant characteristics, size of the viscosity of lube is directly between fluidity and friction surface forming of oil film thickness, TIMKEN bearing operating temperature viscosity of lubricating oils are generally 12-15cst.
(Six) solid lubrication in some special using conditions Xia, will small solid lubricant joined grease in the, as joined 3~5% of 1th, II sulfide Mo can reduced wear, improve anti-pressure heat capacity, for high temperature, and elegant, and high vacuum, and resistance corrosion, and anti-radiation, and very low temperature, special conditions, to solid lubricant joined engineering plastics or powder metallurgy material in the, can made has since lubrication performance of TIMKEN bearing parts, as with bond agent will solid lubricant bond in roll road, and maintained frame and scroll body Shang, Formation of lubrication film, have a certain effect on reducing friction and wear.
(G) supplementary and replacement of the lubricant a. additional intervals due to the mechanical action of the grease, ageing and increased pollution, TIMKEN bearings lubricating base filled in will gradually lose its lubricating properties. Therefore, rank on the lubrication is being added and updated. Would lubricants added interval time for TIMKEN bearing formation, size and speed varies, according to the interval for the approximate running time need to be relubricated.
TIMKEN bearings other than quality, is a very precise parts, is both a high-performance bearings, if used in the course of improperly, not only fall short of expected performance, and very easy to bearing damage, in terms of lubrication must have attention. In addition to lubrication, TIMKEN bearings used in the process, but also those areas require attention.
