Surface cleaning: The cleaning must be combined with the nature of the bearing surfaces and the prevailing conditions. Commonly used method of solvent cleaning method, cleaning mechanical cleaning and chemical treatment method.
Drip lubrication 1.
The drip lubrication is suitable for quantitative supply lubricating oil was bearing components, drip volume generally every 3-8 seconds a drop is appropriate, too much oil will cause increased bearing temperature.
2 cycle oil lubrication
With a pump the filtered oil is supplied to the bearing member, filtered again after cooling through the bearing lubricating oil. Bearing cooling cycle oil can be taken away a certain amount of heat, and therefore the method is suitable for high speed bearing components.
3 oil bath lubrication
Oil bath lubrication is the most common method of lubrication, for low, medium speed bearing lubrication, the bearing part is immersed in by the groove, the lubricating oil by the rotation of the bearing parts brought up, and then to flow back to the sump oil should be slightly lower than the lowest the center of the rolling bodies.
4 jet lubrication
With a pump to the high pressure oil through the nozzle incident bearing, incident on the oil in the bearings in the other end via a bearing into the oil sump. Bearing rotates at high speed, the rolling body and the retainer so that the surrounding air with a relatively high rotational speed to form a gas stream, with the general method of lubrication is difficult in the lubricating oil to the bearings must be used high-pressure injection method, then the lubricating oil spray to the bearing, the position of the nozzle should be placed on the inner ring and between the holder center.
5. Spray lubrication
Formed by mixing with dry compressed air through the sprayer with the lubricating oil mist, ejection bearing, airflow can be effectively cool the bearing and preventing intrusion. This method is suitable for high-speed, high-temperature lubrication of the bearing components.
Can be used to filter the surface is dry clean dry compressed air. Or using a drier and dried to a temperature of 120 ~ 170 ℃, and finally with dry with a clean gauze.
Bearing rust is caused by a variety of internal and external factors, summed up:
1, the metal surface finish (oxygen concentration cell corrosion);
2, the metal material itself, the chemical composition and structure;
3, in contact with the metal surface of the solution composition and the pH value;
4, the ambient temperature and humidity;
5, with the metal surface in contact with a variety of environmental media;
6, another human sweat also lead to rust bearings reason, its pH value is 5 to 6. So, in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves, it should not touch the bearing.
