The bearing 7213 EDA maintenance and repair to ensure reliability of operation, increase the production and economy in order to prevent accidents, ensuring the reliability of operation, improve the production performance and economic performance, and can ensure the joint bearing long time in good condition to maintain the original performance.
Bearing cleaning: general use gasoline, kerosene as the common cleaning agent. Demolition of bearing 7213 EDA maintenance, the first recorded appearance of the bearings, confirmation of lubricant remaining quantity, sampling inspection by the lubricant and began to wash the joint bearing. Cleaning rough cleaning and fine cleaning, placed in a container, metal mesh on the bottom first, make the bearing does not directly contact the container dirt.
1, in the use of the bearing process, regular cleaning is very important. How accurate cleaning bearings? The first joint bearing remove search, first with photography and other methods appearance record. In addition, to confirm that the remaining amount of lubricant and lubricant sampling, and then cleaning bearings.
Cleaning 2, bearing 7213 EDA rough cleaning and washing suspension, and metal frame use the bottom of the container placed on.
3, rough when washing, in oil use brush Su Qingrun grease or adhesions. If the oil migration shift joint bearing, note blend due to foreign bodies such as damage the rolling surface.
4, wash, slowly in the oil migration shift bearing, be hard to stop.
Cleaning agent 5, usually used for neutral without water diesel oil or petroleum, based on demand and sometimes the use of temperature alkaline liquid. Regardless of the use of what kind of cleaning agents, are often filtered confrontation clean.
6, after cleaning, immediately in the joint bearing is coated with anti rust oil or antirust grease.
bearing 7213 EDAs maintenance and judgment: dismantled in order to determine the bearing can be used to check the bearings cleaned.
Maintenance includes: monitoring running state, supplement and replacement of lubricants, periodic disassembly inspection, this is to maintain the best operating conditions of the corresponding mechanical operating standards, regular. As a matter of maintenance in operation, a rotary sound, vibration, temperature, lubricant, joint bearing separation type bearings, can check on the raceway surface rolling body, the outer ring.
Check the raceway surface, rolling surface, with the state, maintain and increase shelf wear, bearing 7213 EDA clearance and damage abnormalities in drop size precision. Non separation of small ball bearings, inner ring with one hand supporting level, rotate the outer ring to confirm whether the large bearings because they cannot rotate, check the rolling body raceway, cage, retaining boundary surface appearance, the importance of joint bearing shall carefully check the higher.
