Remove the process of rolling bearings

Remove the damaged bearing is more often in the motor maintenance do one job. According to the specific operation of equipment condition, process is as follows. Use remove as shown in figure 3 - drawing machine Figure 3-4 a, And figure 3-4 b 4 c. To still can continue to use the bearing, the drawing of the hook should be paid attention to claw on the bearing inner ring end face, as shown in figure 3 - 4 a. When working with smaller, hook can deeply, can choose a suitable size of FIG. 3 Le shown in special chuck, as shown in figure 3 - 4 c to remove. Remove by copper bar percussion with purple copper bar in the bearing inner ring, the copper bar with a hammer. Is worth points within the bearing inner ring should be decorated more than four on the circumference of a circle, as shown in figure 3 - 4 d. Splint set on removing the rotor in the depth of a suitable barrel or bracket, will remove the bearing clamp with two pieces of solid wood and lift. In order to avoid injury of the pier when rotor suddenly dropped lower shaft head, should put a piece of wood or cardboard below, rubber, etc. With board pad in the upper shaft end, struck to remove the bearing with a hammer. Applied in bearing were loose, walking in the rotor, prevent partial inflicts upon, as shown in figure 3 - 4 e. Heat expansion after disassembly when bearing damaged, with the above method is difficult to remove the, can be to abort roller bearing bracket, remove the outer ring, reoccupy gas welding or heating burner, the cylindrical bearing inner ring after heated to a certain degree, with the help of a bearing inner cover can be easily removed, as shown in the above. Outer remove remove interference fit of the outer ring, beforehand in setting several outer shell on the circumference of a circle of extrusion screw with screws, tighten the screws evenly and disassemble. The screw hole cover usual blind plug, the separation of tapered roller bearing type bearing, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly. Taper hole bearing remove remove the small belt tight sleeve bearing, with fastening on the shaft gear support inner ring, the nut back a few times, use block with a hammer beating the disassembly. Large bearing, using the method of hydraulic remove more easily. In the oil hole on the shaft taper hole pressure oil, remove bearing inner ring expansion. Operation, has a bearing may suddenly emerge, it is best to nut used as gear block.
