4. Bearing attachment layout problem: At present, most of the bearing accessories of China's motor are the inner and outer oil cover layout. The defect of this layout is poor sealing effect; the dust inside and outside the motor is simply sucked into the bearing; The wear and tear of the bearing is damaged, and then the layout of the bearing accessory does not work on the heat dissipation, cooling and smooth grease circulation of the bearing; therefore, the running temperature of the bearing is high and the life is reduced; the forming of the motor does not reach a maintenance cycle bearing That is, damage. According to our analysis of the imported medium-sized motor layout; first, all the equipment on both sides of the bearing has sealing equipment; to ensure the internal sanitary of the bearing, and second, to install positioning and cooling equipment on the outside of the bearing; and the oil chamber of the bearing The space is large; this greatly reduces the temperature during the operation of the bearing; and it is excellently smooth; it extends the service life of the bearing. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
5, bearing selection problems: according to our analysis and accounting of motor bearings; bearing faults and bearing selection have a great relationship. From the comparison of China's motor and imported motor; domestic medium-sized motor load side bearing; Usually, the "medium-sized roller bearing" is selected. The radial bearing capacity of the bearing greatly exceeds the accounting value; however, the allowable rotational speed is very different from the actual rotational speed of the motor; the bearing is formed without an additional service life. The bearings on the load side of the imported medium-sized motor are usually selected from the larger "light ball bearings"; on the unloaded side, the "light roller bearings" smaller than the load side are selected; this not only ensures the bearing capacity of the bearings; The promised speed greatly exceeds the actual rotational speed of the motor; therefore, it can reach or exceed the service life of the bearing.
Transformation process and methods:
Through our analysis of the above various motors; over the years, we have carried out the transformation of the motor bearings in our factory and received an outstanding role. Our factory was built and put into production in 1958; in the early 1970s, we targeted the end caps. The problem of the sliding bearing type "motor" was carried out for the transformation of the bearing; and accumulated many experiences. In the 1980s, the factory introduced and put into production of imported boilers and all the subordinate equipment. After many years of operation and several inspections; We have found out the advantages of the layout of the imported medium-sized motor; and contacted the practice layout of the domestic motor of the factory; further transformation.
In the transformation of the motor bearing; the first to prove the selection of the bearing; found that the above problems; that is, the ab initio accounting, depiction and selection of the bearing. The transformation plan is based on the practical layout of the motor; try to use imported motor bearings And the layout of the attachments is depicted. Through the calculation of the motor operation after the transformation; the life of the bearings is mostly more than doubled; the problem of frequent damage of most medium-sized motor bearings is handled; and the safe operation of the unit is supplied. Securely secure.
