Improper cleaning stainless steel bearing burn

When the burn problem caused by improper cleaning stainless steel bearing, the purity of the current detection method has the following three: quality standard test, microscopic counting method of test, automatic test particle counting method. A: the quality standard test. According to the regulations of the state of JB/T ⒛ 50 - 2005 standards, divides the impurity cleaning of stainless steel bearings to the cleaning fluid, after cleaning fluid filtration, drying, weighing, calculate the quality of the impurity particles. Experiment 2: microscope method. Previous step of this method and quality standard, the different cleaning fluid is filtered, directly with a microscope observation of impurity particles in the membrane filter size and quantity. And still can according to the shape of impurity, determine the chemical composition and content of impurities. The method most suitable for the determination of SKF bearing precision bearing cleanliness. 3: automatic particle counting method test. Automatic particle calculation method and quality standard, microscope method is different, it is using the theory of photoelectric principle, direct method determining the quantity of impurity particles and size. The precision of this method is higher, generally applies to high cleanliness requirements of stainless steel bearing. Bearing the reasons for burns burn injury (so-called SKF bearing status refers to: the bearing raceway wheel, roller and cage in the rotation sharply fever until discoloration, softening, deposition and damaged. The main cause of bearing burn is due to the bad lubrication stainless steel bearings, may use the informal lubricant, or lubricant too much, too little, is not correct. It is possible that too much load ( Preloading is too big) 。 Speed is too large. Clearance is too small. With water or other foreign matter invasion. If the above two cases are not the shaft, the accuracy of bearing box, shaft deflection. See here, I think everyone wants to know the solution, first of all, to study lubricants and lubrication method, selection of stainless steel bearing lubricant, and its dosage, and choice of SKF bearing must be corrected. Study to cooperate, bearing clearance, and preloading, and improve the sealing device. Check the shaft and the precision of the bearing housing.
