Application of lubricating oil in bearing maintenance

What role can lubricating oil play in the maintenance of bearings? What is the connection with the maintenance of the bearing?

The first is the speed of movement: the higher the speed, the easier it is to form an oil wedge, and a low-viscosity lubricating oil can be used to ensure the existence of the oil film. If the viscosity is too high, the resulting impedance will be large, the heat will be relatively large, and the temperature will be too high. When the running speed is slow, the viscosity of the oil is used to carry the load, so lubricating oil with higher viscosity should be selected.

The "five determinations" and "three filtrations" of equipment lubrication work are effective methods to standardize and standardize the daily lubrication technology management work and ensure that the equipment lubrication work is done well. Its content is: five set:

Personnel appointment: The work of the workers must be fixed, and the lubricating workers are responsible for the division of oiling, oiling, and cleaning and changing the lubricating parts of the equipment, and they are responsible for completing the lubrication of the equipment together.

Bearing load: Generally, the greater the load, the higher the viscosity of the lubricating oil. Low speed and heavy load should consider how much oil load is. c. Working temperature: When the temperature difference is relatively large, the oil with high viscosity index should be selected. Under high temperature conditions, the oil with high viscosity and flash point, good oiliness and anti-oxidation 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 position and lubrication point of each piece of equipment. Implement fixed-point refueling.

Qualification: Determine the type, brand and quality requirements of the oil required for the lubrication parts of the equipment. The quality of the oil must pass the test.

Quantitative: Determine the number of oil changes for each oil supply part, and implement oil consumption quota management and quantitative oil changes.

Regularly: Determine the cycle of adding and changing oil for each lubricating part, refuel, refuel, clean and change oil according to the specified cycle, and for the oil tank with a large oil storage capacity, sample and test periodically according to the regulations to determine the time and work content of the next maintenance.

Working environment: In the environment of water vapor, it should be noted that the oil with strong anti-emulsification, oily and anti-rust properties should be selected. In the environment with large dust, dust-proof sealing should be paid attention to. Some gases are corrosive, and oil with good corrosion resistance should be selected in this environment. ④ Lubrication work should do a good job of "five determinations" and "three filtrations"
