The thrust bearing shall be inspected after installation. When installing the thrust bearing, first check the Install Thrust verticality of the shaft ring and the shaft centerline. The inspection method is:
fix the dial indicator on the end face of the box shell, make the contact of the dial indicator push against the Install Thrust raceway of the bearing shaft ring, rotate the bearing, and then observe the pointer of the dial indicator.
If the shaft ring is not perpendicular to the shaft centerline, the pointer will Install Thrust swing. The pointer of the dial indicator is relatively long. If the box shell hole is deep, you can also choose to use the extended dial indicator for inspection.
which indicates that the thrust bearing is installed correctly. If the thrust bearing is installed reversely, if this happens. The bearing cannot work normally, and the mating surfaces of the bearing will be seriously worn. The difference between shaft ring and seat ring is not obvious, so extra care should be taken in assembly.
Moreover, a clearance of 0.2-0.5mm shall be reserved between the thrust bearing seat ring and the bearing seat hole when installing. This clearance is used to compensate for the error caused by inaccurate processing and installation of parts. In case of accident, when the center of the bearing ring is offset during operation,
this clearance can play a great role to ensure its automatic adjustment and avoid contact friction, Enable the Install Thrust bearing to operate normally. Without this clearance, the bearing will be severely damaged. The bearing is damaged and cannot be used.
Remove the antirust oil on the bearing surface. 1 Mix the industrial high Install Thrust efficiency degreasing powder developed by us with water at the rate of 1% to 3%, put the bearing ring into the liquid, heat it to 70 ℃ to 85 ℃ and soak it for 30 minutes (intermittent stirring is required),
stop heating, immerse the bearing ring in water one by one until it is self cooled to about 40 ℃, and brush it Install Thrust with a brush. In particular, the working spherical surface of the bearing should be brushed several times. During brushing, the bearing ring cannot leave the water surface Note:
this liquid can be reused after removing the oil droplets floating on the water surface; 2. Rinse twice with water at about 40 ℃, and the two Install Thrust rinsing waters can be reused; When the oil is heavy, brush twice with 3% proportion and reconstituted cleaning solution;
Put the bearing ring with basically empty and dry water into the oven for 60 degrees / 10 minutes, and then Install Thrust adjust it to 110 degrees / 10 minutes to take it out; The removed bearing ring replacing high temperature is easy to rust.
Treatment method: quickly pour it into the sealing barrel, spray a little anhydrous ethanol (industrial alcohol) while pouring it, pour a layer of ring and spray a thin layer of alcohol (don’t spray too much), seal the cover of the sealing barrel, store the bearing ring in the sealing barrel and take it after self cooling. It is stored in a sealed barrel to prevent rust.
Take it out only when coating is required. Take as much as you want and apply it while taking it, or immerse it in the coating or spray it. As long as the bearing ring is coated with glue, it will not rust.
After removal, the barrel cover shall be sealed in time to minimize the contact of the bearing ring with air. According to the local environmental humidity or sealing conditions, it can be stored for 3-6 days without rust.
