IKO plane bearing fault maintenance attention to matters

Surface bearing fault characteristics show serious trouble didn't surpass a week time, equipment, the capacity is bigger, faster, its distance from a relatively short time. Therefore, the practice of bearing fault diagnosis, once found, its advanced function, should be resolutely sure IKO bearing fault, repair as soon as possible. 1, selection of shaft and the bearing chamber tolerance and control: into the plane after bearing bearing pressure should be sensitive rotation without block. If there are any apparent rotation not sensitive, indicates the size of the shaft is too big, tolerance to downgrade. Such as IKO 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. When control the shaft and the bearing chamber tolerance so also want to control the roundness, at present many domestic manufacturers to control the tolerance to stop, only without the roundness stop control. 2, bearing assembly way: since the bearing is high precision products, such as improper assembly on bearing channel formation damage easily, cause damage of bearing. IKO bearing should have a special mould, when it is assembled cannot knock at random, only small circle of stress when pressure into the shaft, pressure can force the circle circle. Assembly request when using pneumatic or hydraulic, lower die when being connected to outside the state, if there is a inclined plane bearing channel will incur due to mechanical damage, and make the bearing guide ring. 3, the assembly to avoid foreign bodies: bearing dynamic equilibrium in loaded on the rotor will easily generated when the dynamic equilibrium of internal iron into bearing, so it is best to install bearing before do dynamic balance. There are some manufacturers in order to assemble bento, assemble indoor apply some oil or grease in the bearing when the smooth effect, but often operators good amount of it is hard to control, if oil or grease in the bearing indoor storing up more, when IKO bearing rotating along the axis into plane bearing internal easily. Bearing chamber it is best not to apply oil or grease, if must apply to control shall not be storing up in bearing interior. 4, paint, rust prevention: 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. Many manufacturer would think that is the problem of bearing before, after our propaganda from time to time, motor factory now has realized mainly is a question of insulating varnish. The problem is mainly due to the insulating paint volatilizes the acid under certain temperature and humidity of corrosive substances, the plane IKO bearing channel invite IKO bearings after corrosion damage. Asked the title can be to choose good insulating paint, before and after drying ventilation assembly after a period of time. We should make our is in this and other country alarmed bearing components, failure is often a very fast and very suddenly. Thought it was two hours later, the example on the digital measurement of the rotor shaft. In these fake bearing fault diagnosis, we should pay attention to high quality surface bearing usually equipment time domain spectroscopy and vibration conditions, this kind of thing in cumulant is normal, abnormal spectrum so that sure when IKO bearing faults in time, prevent the equipment accident.
