From smooth bearing stiffness and the influence of roughness

Avoid smooth bearing has high bearing can, impact resistance, high temperature resistant, the smooth ability strong features, especially suitable for overloading, low-speed, reciprocating or swing, difficult to smooth and constitute the place of the oil film, not afraid of the water and other acid erosion and erosion. Avoid smooth bearing products have been widely used in metallurgical continuous casting machine, rolling equipment, mining machinery, mould and hoisting machinery, textile machinery, wind power generation, shipping, steam turbine, water turbine, injection molding machine and equipment consumption line. Wear resistance is one of the common shaft sleeve. Avoid smooth bearing materials is superior performance: 1. Extremely high wear resistance, low wear rate 2. Since the smooth performance is good, low friction coefficient of 3. High impact strength, good toughness. 4. Good resistance to chemical corrosion resistance, resistant to almost all of acid and alkali salt medium ( In addition to the concentrated sulfuric acid, concentrated hydrochloric acid, a few organic solvents) 5. Exudation of non-toxic, tasteless, no 6. Flexible, shock absorption; Good self healing, bibulous rate is extremely low. 7. Mechanical performance is good, can accept big impact and load, due to its good toughness, can effectively maintain the eight other parts from mechanical damage. Good low temperature resistance, even in the - 176 ℃ when the embrittlement. Avoid smooth bearing aging from looking for this reason: a, intense vibration is due to the motor be there is something wrong with free smooth bearing vibration. Appear this kind of condition that we should change the same model of new free smooth bearing. Is the cause of the two, with tight ball and slide clearance is too small, torque and friction increases, the smooth bearing operating temperature is too high. When the device to try to adjust the right free smooth bearing radial clearance. Three, data is tired due to metal fatigue, avoid smooth bearing raceway and appearance of the balls and debris on the smooth fat, led to the increase of noise. So we should think from smooth bearing information normal tired, change is the new bearing. Four, pollution, corrosion, check and ball on the appearance of corrosion can appear red, brown punctate. Avoid smooth bearing processing roughness: about the influence of hardness and roughness implemented, avoid smooth bearings and steel shaft processing roughness tend to increase in sliding sound, just avoid soft smooth bearing material compare with, so the sliding will make rough surface deformation and flat, as a result, it is not very big, the influence of the steel shaft material is hard, makeup look rough, there is no change, and its influence is considerable.
