Machine tool shaft parts, usually with rolling bearings or sliding bearing assembled into an organic whole, and rotate at high speed, can sometimes produce high heat.
If not promptly eliminate, this phenomenon will lead to 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, which not only affect the accuracy and machining accuracy of machine tool itself, but also the bearing burn out.
The cause of the spindle bearing heating and its elimination method shown in table a.
The cause of the fever and its elimination method (rolling bearings
1)
Reason: the belt too tight method: make the elastic of the belt can be adjusted properly,
2)
Reason: different method of heart: main shaft bending or casing hole repair spindle or box (
3)
Reason: method of assembly quality low: improve the quality of assembly,
4)
)
Bearing damage method: replace the bearing (
5)
Reason: a: poor lubrication bearing installed base knowledge, learn it again next article: bearing the common problems in technical manual
