1. The installation
Usually inner and outer inseparable to heart bearings, inner circle is often adopted a tight fit axis; Outer ring and a hole is used with a loose. Right now usable pressure will be pressed on the shaft bearing first, then bearing load bearing even coaxial together the holes. When pressed by the assembly sleeve with soft metal, such as copper or mild steel all can. Inner sleeve is slightly bigger than trunnion, outside diameter is slightly less than the bearing inner circle raised edge. Bearing to simultaneously in shaft and a hole, in the sleeve and bearing between plus one linking piece end. The aperture is slightly bigger than trunnion, outside diameter is slightly less than bearing outside diameter. Its role is to prevent bearing outer ring all hole bend or stuck. The sleeve pressure pressure can be machinery's, also but hydraulic pressure. But absolutely not direct hammer blow ring width. Because of thin-walled collar hardened parts, hammering easy generation surface crack.
2. Heating installation
Installed a surplus for the collar with force and bearing size and cooperate with a related to the size of the surplus quantity. For large surplus quantity of medium, large bearings, often USES the method of heating installation. Hot outfit bearing in even before the tank heated to 80 ℃ ~ 100 ℃, and then removed from oil installed in shaft. When heated to bearing should not be put in the tank bottom, in case the impurities in the precipitation into the bearings. And shall strictly control the oil temperature not over 100 ℃. According to the bearing batch size still can use other electrical heating methods, such as induction heater, electrothermal board and electric furnace, etc.
3. Remove
Remove them circle and shaft is tight, outer with a hole with a loose with not points of bearing, first the shaft bearing housings with from out the hole, and then from the shaft bearings are removed. Remove the internal and external circle can divide bearing, first the shaft with inner circle is removed, then inner circle removed from the axis; The bearing outer ring from the hole and out. From the shaft bearing removed or bearing inner circle on a shaft can be removed by the press. Also can use screw institutions. When outside all hole in the tight with, can press the outer pressure institutions will be.
