    release time:2021-09-13  viewed:436次
     With the wide application of mechanical equipment, the functions of various bearings are becoming more and more obvious, the market development is becoming more and more clear, and the demand for bearings is also increasing. Needle bearing is a form of bearing. The use of needle bearings can reduce the friction between the shaft and the shaft, which is its main advantage, so it is widely used. The cleanliness of the bearing has a great influence on the use of needle roller bearings, and readers can learn about it through this article.
    One is the effect of vibration. The test results of the test center show that cleanliness seriously affects the vibration level of needle roller bearings, especially in high frequency bands. Needle roller bearings with high cleanliness have low vibration speed values, especially in high frequency bands, and low vibration can reduce bearing wear.
    The second is the influence of noise. The effect of dust in needle bearing grease on noise was tested, and it was proved that the more dust, the greater the noise.
    The third is the influence of lubrication performance. The decrease in the cleanliness of needle roller bearings not only affects the formation of the lubricating oil film, but also causes the deterioration of the lubricating grease and accelerates its aging, thereby affecting the lubricating performance of the lubricating grease.
