Reinforced roller housing mounting check

Every time you change the roller should be checked, the faulty parts of the timely repair and replacement.

(1) the implementation of roller bearing seat assembly, inspection system and operating process standards, regular cleaning, inspection, replacement. In the bearing assembly operations as much as possible to keep the operating environment clean, to prevent sand, iron and dust into the bearing box.

(2) the work roll bearing before the installation of the roller roll neck to fully clean and confirm the roll roll no kneel, bumps and roller neck oil tank of the water chestnut grinding smooth, end cover, oil seal intact, in the roll bearing And roller roll neck evenly coated with oil mist oil.

(3) control the roller bearing clearance. The installation of the bearing box should be appropriate to tighten the bearing box in the bearing fully tightened, the mother should be back to the thrust ring and the inner ring between the side to ensure that there is 0.5-1.0mm clearance; bearing box The connection bolts should have to prevent retreat measures, to avoid the roller collar and bearing inner sleeve relative movement.

(4) often on the bearing temperature thermocouple data recording, analysis and verification, found abnormal, timely processing.

Bearing the routine maintenance of the work: the bearing in the operation for some time, whether or not there is an exception, the bearing should be removed from the bearing seat for decomposition check. According to the operation of the mill, the general every three months (in exceptional circumstances, each time the roll must be carried out once). When servicing, remove the dirt from the bearing cover and remove the bearing in the correct order and clean it. Cleaning, with kerosene cleaning twice, check the bearing inner and outer ring wear, with compressed air to detect oil mist lubrication pipe is smooth. After cleaning, in the bearing into the bearing in turn, the bearing outer ring and the bearing box wall position and disassembly before the turn 90 ° to ensure that the bearing circumference force uniformity, extend the bearing life.
