On June 19, wafangdian spherical roller bearing, the author explain for you: spherical roller bearing heat elimination method of machine tool shaft parts, especially the main shaft, and rolling bearing (commonly
The 6408 series deep groove ball bearing)
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.
(
1)
Reason: low bearing precision method: choose regulation accuracy grade bearing.
(
2)
Reason: different method of heart: main shaft bending or casing hole repair spindle or box.
(
3)
Reason: the belt too tight method: make the elastic of the belt can be adjusted properly.
Heating method: (spherical roller bearing
a)
Reason: poor lubrication methods: choose brand lubricating materials and proper clean.
(
b)
Reason: low assembly quality methods: improve the assembly quality.
(
c)
Reason: bearing inner shell run laps method: replacement bearings and related safe and durable wear parts bearing (
