High-performance plastic bearings are often processed from self-lubricating modified engineering plastics; the friction coefficient of plastic bearings directly affects the service life of the bearings and the required driving force.鹊 å© å© å‡° 凰 å²¢ å²¢ å²¢ å²¢ Σ Σ Σ 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 ã“淌刈 ã“淌刈 ã“淌刈 /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
In addition, CSB researchers also found that the friction coefficient of self-lubricating plastic bearings is also affected by the surface finish of the grinding shaft; after research, it is found that the lower the smoothness of the shaft, the higher the friction coefficient will be added; the axis of the shaft is in the Ra0 range. 4 ~ 0. 8; at this moment has a lower coefficient of friction.
The unevenness of the friction coefficient of self-lubricating plastic bearings depends to a large extent on the self-lubricating function of the materials used in the bearings; China CSB Company also found that in addition to the plastic bearing data itself, the bumps of the plastic bearing operation also received a lot of bumps. The influence of external factors; such as operating load, speed of movement, ambient temperature, etc.
CSB engineers found in experiments that plastic bearings CSB-EP and CSB-EP13 have lower friction coefficients below 80 °C; new plastic bearings CSB-EP3 and new material CSB-EP3G have lower friction at 130 °C The coefficient; while the high-performance plastic bearings CSB-EP5 and CSB-EP5Z still have a very low friction coefficient of about 0.11 at high load and 160 temperatures.
CSB engineers have made the following conclusions in tens of thousands of laboratory experiments: the friction coefficient of self-lubricating plastic bearings decreases with the addition of working load, increases with the addition of moving speed, and increases with the increase of working temperature.
