Preventing failure of IKO bearing joints, need what to problem note

First of all, reasonable structure design and equipped with advanced, just can have a longer IKO bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. 1, paint, rust preventing paint rust is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound is very big, remove the bearing has serious rust phenomenon. Before a lot of manufacturers will think is a problem of IKO bearings, motor factory now have realized mainly is a question of insulating paint, varnish comes out of the problem is mainly due to acid corrosion formed under certain temperature and humidity of material, the bearing channel after corrosion result in bearing damage. The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time. Bearing's life closely related to manufacturing, assembly, use, and must be made at each link only in the use of joint bearing pay attention to these matters needing attention, to make the bearing is in optimum operation state, so as to prolong the service life of bearing. In order to be able to ensure that the bearing has been in a good condition, regular maintenance overhaul is necessary, so as to prevent accident and what shall, enhances the enterprise the production efficiency, cost savings. Here want to be engaged in the professional maintenance of the bearing, and must have the standard system operation process, including running state, lubricant, remove regularly, noise, temperature, and so on a series of tests. 2, the choice of the shaft and bearing tolerance and control into the IKO bearings bearing pressure should be flexible rotation without blocking. If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade. Such as bearing pressure into the shaft by hand after the rotation has obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big. So in good control of shaft and bearing also want to control the roundness tolerance. 3, foreign material to prevent bearing assembly when loaded on the rotor to do dynamic balance will easily generated when the dynamic balance of iron into internal joint bearing, so it is best to install bearing before do dynamic balance. There are some manufacturers in order to convenient assembly, assembly in bearing indoor coated with some oil or grease lubrication effect, but usually operators good amount of it is hard to control, if oil or grease in the bearing interior storing up more, in the bearing rotates along axis to the bearing inside easily. Bearing is best not to apply oil or grease, if must apply to control shall not be storing up in bearing interior. Joint bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in IKO bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. The main task of the joint bearing failure analysis, which is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid sudden IKO bearing early failure.
