Two measures for smooth protection of deep groove ball bearings
First, the detection method of bearing smooth protection
If the ultimate speed of the selected bearings is not satisfied, the use of certain improvement techniques shall be adopted to make progress in order to reach the desired request. About the category of C/=10, because the limit speed increase is very small, so it can not be considered, that is, according to the value of f1=1.
When the operation condition is 0.1C under the load bearing, because the rolling body raceway contact with the name of the contact stress increases, so that the task of bearing measures decreased, smooth agent function relative to the better, therefore, deep groove ball bearing limit speed will be increased echo. Due to abnormal operation should be rocking rumble, the emergence of functioning is resolved in a timely manner, deformity lubricants are clean and clear, if the smooth agent has become dirty, there will be wear particles or pollutants, reduce the operation measure, there will be the same. To be out of bounds before all coated with anti rust oil, room temperature should be controlled at 0-25 degrees, absolute humidity should be maintained at 45%-60%. Smoothing agents, measurements, etc. are monitored in three ranges.
Second, the detailed method of bearing smooth protection
1, smoothness of the main
Line should maintain smooth oil circuit, check the sealing condition of sealing parts timely, change the protective seal. To stop running the market monitoring, from music. In the heavy load, high speed, low temperature and other conditions, oil slick. When the speed is very low, to prevent internal interference, into the bearing can be filled with shell time. The best to fill the bearing and deep groove ball bearing shell time 1/3 and 1/2 as the standard, if too much fat, because the heat will make the mix sweep, fat metamorphosis or improved of chin.
2, smooth classification
High and low attention to bearing smooth technology. High speed should only be filled to 1/3 or less. As the progress and bearing level; appropriate increase clearance; use special talents and maintain improved frame structure; smooth change forms, such as the adoption of oil and gas, oil mist and radiation smooth; improved icing conditions etc..
3, the use of smooth fat
Oil and grease into smooth smooth, smooth smooth fat strengths equipment easy, not easy to leak into the grease, water, gas and other impurities have the power, so under normal conditions the broad use of grease smooth. Can smooth the oil film in the name of our activities will be absolutely separated from each other, will not take effect due to the rough point contact to wear appropriate, can guarantee to the task of life period is still maintain stable function and filled precision.
4, the amount of filling in the bearing is excessive.
Centripetal bearing on the acceptance effect of connected load, because the load of the rolling unit accept increase, the conflict barrier added, have a fever can reduce, smooth and icing conditions become worse, and to maintain the shelf stress increase, therefore, must be based on the bearing type and load angle size, the speed limit of deep groove ball bearing once F2 multiplied by the coefficient of increase mobilization. Requests for storage and control of the environment are more stringent, such as measurements, humidity, etc.. |
