The methods of dealing with the roller bearing in the operation of the heating phenomenon

Bearing assembly appearance and cooperate with the appearance of parts, such as a bruising, rust layer, abrasive dust, sand, dust and dirt, a bearing device, form the assembly position is not correct; Two of these attachments constitute abrasive, easily galling roller bearing work appearance, affect the assembly quality. Therefore, device before dealing with the journal and bearing shell hole appearance, shoulder, face, and connecting parts, such as bushings, gasket, with the end cover of appearance, stop check carefully. If there is any rust layer, usable fine file file, fine cloth, at the same time also want to clean up the bearing assembly appearance and things immovably attached to the connecting parts. Bearing on the use of the advertent items: INA bearing is fine parts, its use should be cautious to stop accordingly. No matter how high performance bearing use, if use undeserved, will not get the desired performance. About the use of the bearing pay attention to the following matters: (1). Adhere to the bearing and the surrounding clean. Even the eyes can't see the little dust, will also affect roller bearing. So, to stick around, clean the dust from invading bearings. ⑵。 Watch carefully. Give bearing intense impact in practice, which will produce scar and creasing, become the cause of the accident. Serious situation, can crack and fracture, so must pay attention to. ⑶。 Use the appropriate operating tools. To prevent the substitution of existing tools for, it is necessary to use appropriate tools. Such as special sleeve, press, etc. ⑷。 To pay more attention to the bearing corrosion. INA bearing operation, why hand sweat will become rusty. To pay more attention to operation with clean hands, it is better to try to bring gloves. ⑸。 Didn't finish the work before, the device don't unpack the bearing, so as to avoid pollution. Roller bearing of life than speed are more sensitive to load and so on multi-stage transmission shaft, if possible, should put greater reduction in the later series; Allocation of main shaft bearing, if possible, appropriate load point and the gap between the bearing support, try to reduce the load of main shaft bearing, and tried to spread to the main shaft bearing the load on the smooth, prevent shock and vibration, it is of the bearing device can request the shape and position precision is high enough, bearing clearance, and cooperate with the correct bearing device precision is good. Machine tool shaft parts, especially the main shaft, ordinary and bearing or sliding bearing assembled into an organic whole, and rotate at high speed, can sometimes produce high heat. The phenomenon such as cleaning not in time, will cause bearing overheating, and makes the corresponding parts temperature rise and thermal deformation will occur, serious when they make the main shaft and tail frame range is high, it not only affect precision and machining accuracy of machine tool itself, but also the bearing burn out. The reason of roller bearing heating and sweep method as shown in chart a. Bearing the cause of the fever and its cleaning way 1, reason: low bearing precision solution: choosing rules precision grade bearing 2, reason: different heart way: main shaft bending or casing hole repair spindle or box 3, reason: belt tight way: make the elastic of the belt can be adjusted properly, reason: smooth bad idea: use rules of smooth information and appropriate clean 5, reason: low assembly quality: progress assembly quality 6, reason: bearing inner shell run laps: change bearing and wear parts: 7, axial force is too big to clean, is seal ring clearance request 0. 2 to 0. Between 3 mm, correcting impeller balancing hole diameter and checking the static equilibrium value 8, bearing damage: a change in roller bearing technology consulting, please contact BeiJia bearing technology
