7 kinds of bearings: floor fan fan bearing in there

Bearing lubrication is usually caused by adverse factors include: lubricating oil ( Grease) Inadequate; Oil pipe blocked, etc. ; Lubricating oil ( Grease) There is something wrong with the quality; Add lubricating oil is not on time, Grease) ； Lubricating oil ( Grease) Containing impurities. Cause bearing damage is not all of the bearing damage can be repaired, but for each of the damage of bearing considering repair or replace new bearing before, must be the reason and degree of damage assessment in order to avoid or reduce the damage once again. Should adjust the belt elasticity; Coupling correction, & amp; emsp; & emsp; Two motor end cover or bearing cover not assembled, it is usually not parallel, bearing is not in the correct position. The cause of the problem analysis: through the study found that loud noises in the process of tool change occurred in the manipulator slotting tool stage, the reason is that the spindle must stop location error problem and spindle tool change reference point drift problems. On the bearing rotating speed, bearing is according to the type of bearing, size, precision, cage type, load, lubrication, and cooling way. The axial removed with axial wrench, splash lubrication rely on the fuel tank of the panting of the rotating parts and splash up supply of lubricating oil bearing, bearing is suitable for high speed. After improving design, has high bearing capacity, guard and roller end face of the new structure design, not only can improve the bearing axial bearing capacity, at the same time improve the roller end face and guard contact area of the lubrication conditions, improve the use of bearing performance. Enterprise paper machine production line, dryer, operating side shaft head wear, bearing axial runout, often bearing inner ring rupture is caused inside short time, to the enterprise have serious impact on normal continuous production. Lubricating oil film, at the same time, through experiments performed on magnetic especially applying a current ( When the applied external magnetic field) , can increase the bearing capacity of oil film bearing, and can in definite extent, reduce the temperature influence on the oil film viscosity. In the process of motor running, if the circle between bearing and roller bearing, or between the motor shaft and bearing shaft current, motor bearing service life will be greatly reduced. Opposite of self-excited vibration and forced vibration, the vibration or are not - — Stable grinding; Or is occurring and soon make amplitude increase - — Unstable grinding. Bearing grinding speed of workpiece rotary speed and the diameter of the bearing grinding surface is related to the speed of the workpiece to a larger impact on the surface roughness and grinding cut marks, low speed grinding surface causes ripples, increase the surface residual stress, high speed will cause the grinding surface.
