According to the data in the installation of rolling bearings damage accounted for 20 percent of the bearing damage, how to reduce damage when installing the bearing it? Below for detailed installation bearing specific requirements of the venue, the venue must be kept clean and dry to prevent iron filings, sand, dust, moisture from entering the bearing.
Hand hammer, copper rod, sleeve, special plate, snail mosquito fixture, presses rolling bearing installation tools used, the amount of a vernier caliper, micrometer, dial gauge, but according to the different models of bearings select a different tool.
Choose to use the right tools, can be installed on the bearings, installation, pay attention to no bumps, rust layer, the presence of debris, sand, dust and dirt, if any, will result in the installation difficulties, must maintain imports the surface of the bearing assembly and parts associated with the surface clean.
In addition to the cleaning of the surface of the bearing assembly and co-ordinated with the surface of the part, but also pay attention to the journal, the surface of the bearing seat shell hole, the end face of the shoulder, and connecting parts such as bushings, gaskets, end caps such places there is no corrosion layer? , If any, may be out with a fine file and fine emery cloth lighting, and then install it.
1, on the speed of the bearing, the bearing is a bearing type, size, accuracy, maintaining frame type, load, lubrication, and the cooling mode and other factors determined.
2, the installation and removal of the bearing, in specific applications often need to demolition and installation, to ensure the detection and repair of their land. Bearing inner and outer rings can be installed, such as: cylindrical bearings, needle roller bearings, and tapered bearings very combination of this occasion. The cone pass automatically aligning ball bearings and self-aligning roller bearings in sleeve on helping, the same simplified installer.
3, in some cases rolling bearing preload is applied to increase the rigidity of this procedure is usually used for deep groove ball bearings, inner and outer rings bias to the angular contact ball bearings and tapered roller bearings, shaft bending, shaft or bearing housing tolerance variations , with the error will lead to the eccentricity of the inner and outer rings. The to prevent eccentric angle through large, automatically aligning ball bearings, self-aligning roller bearings, aligning bearing is the better choice. Voice frequency and torque move bearings are produced in manufacturing high-precision scales, small voice and torsion. Deep groove ball bearings and cylindrical roller bearings combined low voice, low torque requirements of the occasion.
