What is the main role of lubricating oil in bearing maintenance? What is the connection between bearing maintenance? Firstly, the speed of movement: the higher the speed, the easier it is to form an oil wedge. Low viscosity lubricating oil can be used to ensure the presence of an oil film. Choosing a viscosity that is too high will result in high impedance, high heat generation, and may lead to excessive temperature. When the operating speed is slow, the load is carried by the viscosity of the oil, and lubricating oil with higher viscosity should be selected.
The "Five Determinations" and "Three Filters" of equipment lubrication work are effective methods to standardize and standardize daily lubrication technology management, ensuring good equipment lubrication work.
Its content is: Five determinations:
Personnel selection: It is necessary to determine the work of the workers, and the lubrication workers should divide the labor of oiling, adding oil, cleaning and changing oil to the lubrication parts of the equipment, each taking their own responsibilities, and jointly completing the lubrication of the equipment.
Load bearing capacity: Generally, the higher the load, the higher the viscosity of the lubricating oil selected. Low speed heavy load should consider the load of the oil product.

Working temperature: When there is a large temperature difference, oil with a high viscosity index should be selected. When working under high temperature conditions, oil with high viscosity and flash point, good oil and antioxidant stability, and corresponding additives should be selected. When the temperature is not high, low temperature resistant oil with low viscosity, low moisture content, and low freezing point should be selected for work.
Fixed point: Determine the lubrication parts and lubrication points of each device. Implement fixed-point oil supply.
Quality determination: Determine the type, grade, and quality requirements of the oil required for the lubrication parts of the equipment. The quality of the oil must be tested and qualified.
Quantitative: Determine the quantity of oil to be added and changed at each refueling point, implement fuel consumption quota management and quantitative oil change.
Regularly: Determine the oil change cycle for each lubrication part, add oil, clean and change oil according to the prescribed cycle. For oil tanks with large storage capacity, sample and test according to the prescribed cycle to determine the next maintenance time and work content.
Working environment: In environments with water vapor, it is important to choose oil products that are highly resistant to emulsification, oily, and have good rust prevention properties. For environments with large dust, dust sealing should be taken into account. Some gases are corrosive, and in such environments, oils with good corrosion resistance should be selected.
