Adhere to the bearing cleaning maintenance requests

Due to the relative motion of the rolling element and raceway of dust and pollutants into, make the rolling element and raceway appearance produces wear and tear. Wear quantity is large, it is bearing, noise, vibration, reduce the operating precision of the bearing, thus directly affects the accuracy of some hosts. So for some silent mechanical bearings, daily care is mainly guard against pollutants dust intrusion. 1, the influence on bearing life bearing the cleanliness of the needle roller bearing life is quite large, the influence of the bearing has stopped specially for this experiment, the result is the difference for several times or even dozens of times. The higher the purity of the bearing, the longer the life of the experiment indicate: the smooth oil of different cleanliness had a great influence on the ball bearing life. So, to improve the purity of the smooth oil can prolong bearing's life, in addition, if the smooth oil containing sewage control under 10 um, bearing life is growing into 7 times. 2, the impact on the vibration noise bearing experiment center of the experimental results indicate: the degree of cleanliness will seriously affect the vibration of the bearing, especially high frequency vibration. High cleanliness of bearing vibration velocity value is low, especially in high frequency band, the smooth needle bearing grease dust in the experiment, the influence of noise had done to prove that the dust, the more the greater the noise. 3, affect the performance of smooth bearing cleanliness landing, not only affect the smooth and the composition of the oil film, will also accelerate the transformation of smooth fat and its ageing, thus influence on the performance of the smooth fat smooth landing.
