SKF bearing operation failure caused the greatest impact in check

date:2013-03-27

Bearings in addition to pre-installation and installation, more to three steps of installation, it is will have maximum impact for SKF bearings for three faults: a vibration; second, the noise; three is not properly lubricated. Precisely because a lot of people don′t understand these three issues, so here today as we say a good solution for maximum impact for SKF bearings under three of the failure, as well as measures for its solution.
Effects of vibration
Our test center test results show that the vibration level of cleanliness seriously affect SKF bearings, in particular high-frequency vibrations more pronounced. Low vibration speed and cleanliness of high value, especially in the high frequency band.
Effects of noise
Bearing grease dust impacts on noise test, prove that dust as much noise as possible.
Effects of improper lubrication
Lubrication SKF bearing the impact of cleanliness performance degradation has not only affected the lubricant film formation, also can cause deterioration of the grease and to accelerate their aging, thus affecting the grease lubrication performance.
Measures to address the
1, and SKF bearing if are good of lubrication, and correctly of barrier debris and the moisture said oil seal should no wear. However best in open bearing box Shi check bearing and regularly sexual check oil seal. check near SKF bearing Department oil seal of situation, to ensure they enough to prevent hot liquid or corrosion liquid or gas along axis infiltration bearing, oil seal if has wear should as soon as possible replaced.
2, high temperatures often indicates that the bearing is in exceptions. high temperatures may also be harmful to the lubricant in the bearing. SKF bearings to overheat sometimes can be attributed to the bearing lubricant. If bearing more than 125 degree Celsius temperature long operation will reduce the SKF bearing life.
Cause of high temperature bearings including: inadequate or excessive lubrication lubrication lubricant contains magazine and insufficient clearance under heavy load bearing damage oil seals for high temperature friction and so on.
3, check the condition of machines in operation, monitoring, so as not to cause the device to shut down.
A. grease add interval
  Due to the mechanical action, ageing and increased pollution, SKF bearings lubrication of filling in the base will gradually lose its lubricating properties. Therefore, lubrication rank being added and updated. Lubricants added interval time will differ by formation, size and speed of the bearing, require relubrication intervals according to the operating time. In addition, when a case of bearing temperature exceeds 70 ° c, SKF bearing temperature each increased by 15 ° c, it is necessary to use supplementary lubricating grease halving the interval.
  Double-sided sealed bearing is mounted on lipid peroxidation during manufacturing, total operating temperature range and other provisions of performance suitable for the occasion, and filling grease amount is appropriate for the bearing size, grease life can be extremely SKF bearing life, except for special occasions, without relubrication.
B. lubricating oil replacement cycle
  Lubricant oil replacement cycle by the use conditions and different, under normal circumstances, operating temperature 50 ° c with the following, less dust when used in a good atmosphere, replacing it once a year, when the oil temperature reaches 100 ° c for 3 months or less time.
