Influence the factor analysis of the coefficient of friction of the high-performance plastic bearing


31st March 2011 Bearing Technology 0 Comments

The high-performance plastic bearing was often modified the plastic processing of the project by the self-lubrication, life time of size direct influence bearing of coefficient of friction when the plastic bearing works and magnitude of actuator force needed, and cause the level of the instrument operating temperature of the apparatus directly, so the coefficient of friction of the bearing is a performance parameter that the design engineer of the bearing pays much attention to.
In addition CSB research engineers also find the coefficient of friction of the plastic bearing of self-lubrication is still influenced to rubing the axle smooth finish, low cleanliness have, can lead to the fact coefficient of friction increase while being high through the intersection of finding and axle, the ideal range of cleanliness of the axle has a lower coefficient of friction at this moment in Ra0.4- 0.8.
Greasy property of since what the level of the coefficient of friction of plastic bearing of the self-lubrication depends on with the used material of bearing to a great extent, China CSB Company still finds besides own factor of plastic bearing material under study for action, the level of the working coefficient of friction of the plastic bearing still receives the influence of numerous external factors, such as working load, movement velocity, ambient temperature,etc..
CSB engineers find the plastic bearing CSB-EP and CSB-EP13 have lower coefficient of friction in below ℃80 under test, the new plastic bearing CSB-EP3 and new material CSB-EP3G has lower coefficient of friction at 130 ℃, and though high-performance plastic bearing CSB-EP5 and CSB-EP5Z still has extremely low coefficients of friction that make an appointment at high-loaded and temperature 160 about 0.11.
CSB engineers draw the following conclusions in the laboratory tests of as many as ten thousand times: The coefficient of friction of the plastic bearing of self-lubrication is reduced with increase with loaded work; Rise with increase of the movement velocity; Increase with working increase in temperature.
