TIMKEN stainless steel bearing installation operation and maintenance measures

The correct installation of stainless steel bearings is prolong the service life of the guarantee, a lot of people do not have professional knowledge of the field at the time of the installation is not in place, easy to cause the TIMKEN bearing installation is not appropriate, prone to mechanical operation accidents, as a professional mechanical maintenance engineers must understand the bearing installation.
General bearing installation is in accordance with the size, structure, and install the TIMKEN bearings part, and the cloud properties to decide, when installed attention when the pressure is directly added to the ring plane, must the vertical pressure, not through the rotation of the rolling body to exert pressure, bearing installation method general as follows:
Bearing ring and shaft fit way is in transition fit with the bearing seat hole seat, stainless steel bearings with clearance fit with the way it is, in general are relatively easy to install, in the axial TIMKEN bearing should be fixed on the shaft well, so as to avoid the circle to rotate relatively week, causing unnecessary wear. Installation here bearing, rotating mounting means some more, so that the inner ring can be shaft more closely.
The bearing outer ring and bearing seat with relatively loose, inner ring and shaft relatively tight time, can be used to install the bearing when using the professional press to put pressure on the shaft bearing first, TIMKEN, bearings installed in a bearing seat, when pressing installation note bearing inner surface position, then pad a soft casing made of metal, the material is copper or steel can, in the assembly sleeve diameter than the shaft diameter is larger, when the diameter is smaller than the outer diameter of the inner edge, it is necessary to avoid the pressure on holder.
Stainless steel bearings after installation, in order to check for proper installation, to running inspection. Small machinery can be rotated by hand, to confirm whether the rotation is smooth. Check the project caused by foreign body, scars, indentation dysfunctional, due to poor installation, mounting process arising out of the bad moment is not stable, because the clearance is too small, installation error, sealing friction caused by the force is too large and so on. If there is no anomaly can begin power operation.
With a stethoscope to turn the sound of stainless steel bearing inspection, there is a strong metal noises, abnormal sound, irregular, abnormal sound. Due to poor lubrication, shaft or housing poor accuracy, TIMKEN bearing damage, foreign intrusion etc..
