Bearing installation notes
Bearing in the installation should be noted that there are:
1) bearing preparation
Because of the bearing after antirust processing and packaging, so don't come not to open the packing before installation. In addition, the bearing coating of anti rust oil with good lubrication performance, for general use of bearings or filling grease bearings, do not have to clean the direct use of. But for the instrument bearing or used for high-speed rotating bearings, the application of clean oil will rust oil wash away, then the bearing is easy to rust, can not be placed for a long time.
2) shaft and housing inspection
Clean the bearing and the shell, confirm the burr free from the wound or machining. The shell shall be absolutely abrasive (SiC, Al2O3) sand, chip etc.. The second inspection axis and shell size, shape and processing quality is consistent with the drawings. Before installing the bearing, in the inspection of qualified shaft and casing of the coating of the mechanical oil.
Bearing installation method
The bearing installation method is different from the type of bearing and the matching condition. Due to the general multi axis rotation, the inner ring and the outer ring can be used for interference fit and clearance fit, and the outer ring rotation, the outer ring with the interference fit.
(1) press press in general by the press installation installation, can also use the bolt and nut has no available hammer into.
(2) the heating sleeve is mounted to heat the bearing in oil, and the thermal sleeve method for expanding the bearing to be installed on the shaft can prevent the bearing from being affected by unnecessary external forces and complete the installation work in a short time.
Heating matters needing attention:
1) general heating not more than 100.
2) the bearing is not allowed to contact the bottom of the oil groove.
In addition, the heating device can also use the induction heating device to heat the bearing so that the bearing can be expanded and then installed on the shaft.
