INA roller bearing whether maintenance inspection standard - bearing knowledge

To make the INA bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. The key factors affecting the service life of roller bearings for many of the rotating machinery products their service life depends on the key parts in the product more bearing parts of life. Bearing 'free maintenance' is not a one-way bearing will never damage or failure but not damage within a certain amount of time. Here the designers to calculate the service life of the bearing life INA bearing is greater than or equal to the overhaul period of such bearing mechanical products can be 'free maintenance' in the overhaul of mechanical products and replace new bearing can don't need to use a bearing maintenance. Inspect, clean INA bearings will be removed, with photography method such as first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. Immediately after cleaning, coating anticorrosive oil or antirust grease on roller bearings. 2, examination and judgment to judge remove the bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc. About the test results that can be used by bearing the judgement or master of bearing. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, roller bearings shall not be used again, must be replaced. 1) Bearing parts of rupture and defects. 2) The raceway surface material on the surface of the rolling strip. Installed in institutions, there is the part of the one-way bearing a certain temperature, when the hand touch body shell, should not feel hot as normal, and indicates the INA bearing temperature is too high. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ; Roller bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. Determined by one-way bearing structure design parameters of stiffness, flexibility, quality, such as damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. Manufacturing process of the deviation caused by vibration, the smaller the deviation, the less vibration. Roundness, waviness and surface roughness on the surface of the steel ball is the greatest influence on the vibration in the INA bearing parts, followed by the shape of the inner ring and outer ring channel error and surface roughness, is once again the roller bearing cleanliness and quality of lubricant, etc. Operation conditions such as the installation conditions, speed, direction of axial load, quantity, etc.
