1. Oil-bearing axis shall be determined, with the surface of the shaft case whether there injured, projections, etc.
2. Are there any dust or sand attached to the bearing surface of the shell mold.
3. Although minor bruises, projections, etc., if you want to remove oil grindstone or fine sandpaper.
4. In order to avoid the bumps at containment, surface of the shaft and the shaft housing should wipe a small amount of lubricating oil. To bearing shall be mounted on the axis of the inner urging, to bearings mounted on the bearing housing, it shall be in the outer ring biased. To bearing biased, so be sure to pay attention to the power of the vertical and uniform down, partial play will make the bearing injuries. To do this absolutely avoid bias fight.
5. No oil bearing [1] bearing retainer and the sealing plate also must not be biased. Use a hammer and casing installation method is a method commonly used in general, because it will damage the bearings, so do not directly beat. Be sure to FIG. Typically, the sleeve in the middle and beat into the medium. Hammers should lightly beat. On the mechanical structure, the inner and outer ring are a tight fit, use a pad, make sure the power is applied to the inner and outer ring simultaneously pushed into it. If only in the inner ring plus forced into, the dielectric strength will be pressed into the outer ring of the ball and, therefore, can cause scars in the orbital plane. To a large margin of the bearing mounted on the shaft, the clean oil in the bearing is heated to 80 to 90 degrees, so that the inner diameter of the expansion to the installation method, are widely used.
6. The bearing of hardness, there is reduced due to overheating of the consideration, therefore, must not exceed 100 degrees. In this case, bearings must use a wire to suspension, or placed on top of a wire link, the support plate, not placed in the bottom. Bearing reached the desired temperature (100 degrees), it should be immediately removed from the tank, quickly set into the shaft, the bearing will shrink as the temperature drops, sometimes shoulder between the shaft and the bearing end surface, will have a gap, therefore, require the use of tools, the bearing axis to compress.
