Uses when the TIMKEN bearing should use the item wearily

1, selection and control of shaft and housing tolerances: TIMKEN bearing pressed into the bearing should rotate flexible non-blocking. If there is a clear turning not flexible, it indicates that the axis dimensions are too big, tolerance to downgrade. Hand turn after the bearing onto the shaft there is a clear "rustling", the tolerances of the shaft may be too large or the roundness of the shaft well. So in the control shaft and housing tolerances, to control the roundness, at present, many manufacturers to control the tolerance, not to control the roundness.
   2, TIMKEN bearing Assembly method: because the bearings are high-precision products, such as improper Assembly can easily cause damage to the bearing Raceway, cause bearing damage. Bearing Assembly should have a special mold, not free to strike, only small forces when pressed into the shaft, pressure only when large washers. Assembly requires the use of pneumatic or hydraulic, pressure mode when external to the level of State, such as tilt can cause mechanical damage of bearing Raceway, while cooling the bearing rings.
   3, Assembly of foreign body to prevent: TIMKEN bearings mounted on the rotor dynamic balance is easy to do within the dynamic equilibrium of iron filings into the TIMKEN bearing, so it is best to be loaded before bearing dynamic balancing. Some manufacturers to assemble, Assembly in room coated with oil or grease lubrication effect, but operators are difficult to control, Interior accumulates more oil or grease TIMKEN bearings, bearing rotates easily along the shaft into the bearing. Room it is best not to oil or grease the bearing, if not not to control shall not be coated in bearing Interior accumulates.
  4, painted Rust prevention: paint-rust is characterized by multiple sealed motor, motor Assembly has a good voice, but after some time in the warehouse, much of the abnormal noise of motor, remove TIMKEN bearings have serious rust. Many manufacturers are considered to be before bearing problems, through our continuous publicity, motor works have been realized largely insulated paint problem now. Insulating varnishes containing the problem is because of volatile acid in formation under certain temperature, humidity, corrosive substances, corrosion, which cause bearing damage TIMKEN bearing Raceway. That there can only be a good selection of electrical insulating varnishes, and after drying, ventilation Assembly over time.
TIMKEN bearing life is closely related to the manufacture, Assembly, use, and must in every aspect, to put the bearings in the best running conditions, thus extending the life of TIMKEN bearings.
According to the delineation of the TIMKEN bearing fatigue life calculation of fatigue life, inner ring or shaft rotation (in this case, or seating in the outer ring are fixed) delineation of the calculations, total value transfer of total transfer values.
   Move bearing fatigue life test procedures, test method for scaling), try using a function in a way, to content requirements delineated, TIMKEN bearing fatigue life test samples, the number of real tests from the test data to mouth, in other words, the theme of life of bearing fatigue test.
   Lubrication of bearing fatigue life test is enough, maximum restrain control move bearing wear, and enhance the capacity and speed, to bump the TIMKEN bearing fatigue test method for fatigue life of reinforced,.
   TIMKEN bearing fatigue life calculation of fatigue life test and complement each other, two results are enough letters.
   Actually, if each a times of more using, has take has full number of TIMKEN bearing life test, to validation is for by select of bearing in economic Shang of time and labor,, so, bearing life test method is necessary or important of is, in most situation Xia, in using Qian of situation Xia, a scale of calculation method, estimated Sweden TIMKEN bearing life of mouth, has enough of reliability level.
