The grinder should keep a punctual view of the oil temperature, oil quality and oil volume of the main bearing of the mill; especially when the temperature of the main bearing is not normal; the frequency of inspection should be increased; if an abnormality is found, it should be reported in time. In production practice; there are two The situation is the most difficult to numb the grinder and cause a major accident of burning the tile: First, because the bolt of the main bearing upper cover fixed the scraper loosens and the dislocation of the scraper and the fixed oil ring is caused; the smooth oil can not be scraped; The oil groove is dripped on the hollow shaft journal; the bearing bush is short of oil and burned, and the second is because the dust and other impurities block the oil return path of the main bearing base; the fixed oil ring cannot stir the smooth oil from the base oil chamber; Burning tiles due to lack of oil.
According to the normal use period of smooth oil; punctuality, appropriate amount of increase or replacement of smooth oil; and do a good job of storage of smooth oil and waste oil recycling operations.
Appropriate smooth oil should be selected and appropriate additives should be added; this can improve the smoothness of the main bearing of the mill. The main bearing of the mill is characterized by large load and large linear velocity; and impact and oscillation; scale of bearing bush and hollow shaft It is also large; its shape, dimensional accuracy, and further improvement in surface finish are constrained by conditions such as fabrication and processing. Therefore, the main bearing of the mill usually does not ensure complete liquid smoothness; The outstanding gap is smooth (depending on the function and strength of the dip film), which can significantly reduce the friction coefficient; reduce the wear of the bearing bush. Therefore, the primary factor depends on the temperature, the linear speed at which the hollow shaft journal works, and the load received by the main bearing. Choose a smooth oil type.
In the south; 02. 2mx6. 5m cement mill main bearing can choose N220 and N320 industrial gear oil in winter and summer. Secondly, because the working temperature of the main bearing at the discharge end of the mill is higher than the feeding end; Large; so it can be considered that the main bearing at the discharge end uses a smoother oil with a higher viscosity. In the main bearing smooth oil, it should also participate in the stearic acid polarity increasing agent to improve the strength of the gap film; to prevent the split film from breaking.
