The bearing application matters are compared with the usual mechanical parts; the precision of the rolling bearing is high; therefore, the application should be carefully handled accordingly.
1) Adhere to the hygiene of the bearing and its surroundings. 2) Carefully and carefully, if used, the thick and large leaves will give the bearing a severe impact; the bearing will be scratched, indented, cracked and so on.
3) Use suitable things 4) Pay attention to the anti-rust of the bearing to prevent it from being used in wet places; and do not let the sweat get on; wear gloves.
5) The operator should understand the bearing 6) The operating standard for the proposed bearing operation a, the storage b of the bearing, the clearance of the bearing and its surroundings c, the inspection of the dimensions and processing quality of the device part, the operation of the device e, and the inspection after the device f , open the job g, protect the protection (timed view)
h. Precautions for the smoothing agent before the device 1) Preparation of the bearing Because the bearing is disposed of through rust prevention and packaging; therefore, do not open the package before the device.
Others; the anti-rust oil coated on the bearing has an outstanding smooth function; the bearing for normal use or the bearing filled with smooth grease; can be used without cleaning. However, the bearing for exterior or the bearing for high-speed rotation; The cleaning oil will wash away the rust preventive oil; at this time the bearing is simply rusted; it is not allowed to be placed for a long time.
2) Inspection of the shaft and the outer casing to clear the bearing and the outer casing; acknowledge the burrs left by the scratches or machining. There must be no abrasive (SiC, Al2O3, etc.) sand or chips in the outer casing.
Secondly, check whether the scale, shape and processing quality of the shaft and the outer casing can match the drawing.
Before the bearing of the device; apply the mechanical oil on the cooperation surface of the qualified shaft and the outer casing.
The device method of the bearing is different depending on the bearing type and cooperation conditions.
Because usually the shaft is rotated; therefore, the inner ring and the outer ring can be separated from each other by using interference cooperation and void; when the outer ring is rotated; the outer ring is used for interference cooperation.
(1) Pressing device Pressing device usually uses a press; bolts and nuts can also be used; when possible, the hammer can be used for loading. (2) The heat sealing device heats the bearing in the oil and then expands it. The hot-sleeve method on the shaft can prevent the bearing from being subjected to unnecessary external force; the device can be completed in a short time.
