Machine shaft parts, particularly the spindle, generally with Rolling or sliding bearings assembled into one, and at high rotational speed, sometimes it will produce a very high heat. This phenomenon if not removed, will lead to bearing overheating, and the corresponding parts of the machine and the thermal deformation temperature, serious cause spindle and tailstock is not high, which affects not only the precision and accuracy of the machine itself, and will the bearing burn. Spindle bearings causes fever and troubleshooting as shown in Table 1.
Rolling Fever Causes and Remedy
(1) Reason: bearing low accuracy Methods: specified levels of precision bearings
(2) Cause: The spindle bent or cabinet Holes methods: Repair or spindle housing
(3) Cause: belt too tight: Adjust the elastic belt so that appropriate
(4) The reason: poor lubrication Methods: provide grade lubricating materials and appropriate clean
(5) Cause: Low quality of assembly methods: improve the quality of assembly
(6) Reason: Bearing housing laps: Replace worn bearings and related components
(7) axial force is too large: Clean, align the sealing port ring clearance requirements between 0.2 to 0.3mm, correct impeller balance hole diameter and verification of static equilibrium value
(8) bearing damage: replace the bearings
