(1) pulley or coupling disassembly. Demolition, good position markers between the pulleys or couplings and shaft, unscrew the fixing screws and pins, and then use the puller and slowly pull it out. If you can not pull the inner hole pouring kerosene and then pull. If you still can not pull, the available emergency fire around the pulleys or couplings rapid heating with a damp cloth package axis, and continue to throw cold water to prevent heat into the interior of the motor. Assembly, using fine iron emery cloth shaft, pulley or coupling shaft hole sand smooth, pulleys or couplings aligned on the shaft keyway sets, wrought iron or hard wood block at one end of the key pad, gently the key to knocking people tank. The key in the slot to an appropriate degree, too tight or too loose will hurt key and hurt groove too loose will make the belt slippage or vibration.bearing corp

(2) disassembly of the bearing cap. The bearing cover demolition very simple, unscrew the the fixed bearing cap screws, you can remove the front and rear bearing cover. Front and rear bearing outer cover to be labeled on the mark, to a void assembly installed wrong before and after. Bearing cover assembly; cover cover screw through the axle sleeve, plug in a screw out of the end cap, single-handedly withstood Fengyun screws in one hand and turn the shaft so that the bearing inner lid also follow Go hole alignment screws into the top of the inner cover screw holes and tighten, and finally the remaining two screws fitted tighten.

(3) cover the disassembly. Decommissioning of the former should be tagged in the seams of the cover and base, in order to recover. Fixed end cap and then unscrew the screw with a screwdriver and slowly pry under the cover (screw and pry the end cap to be diagonal symmetrical). Front and rear end caps to make marks before and after the mistake to avoid assembly. Assembly aligned with chassis and cover seams tag mounted on the end cap. Insert the screws tighten (according to on the line symmetry precession screws and tightened in several, and should not be loose there tight , so as not to damage the cover). At the same time you want to rotate the rotor at any time to check the rotation is flexible.thin bearing

Disassembly of the rotor (4). Before and after the cover is removed, the rotor can be extracted. Since the rotor is heavy, you should be careful not to damage the stator coil. For small motor rotor, taking a hand upon the rotor, rotor pulled out some, and then the other hand, hold the rotor, the relocation slowly. For large motor out of the rotor, the two each carry one end of the rotor, and slowly the relocation. Assembly, according to the inverse process, to be fed carefully aligned with the stator cavity center.spindle bearings

(5) the rolling bearing disassembly. Removing the Rolling the method and disassembly pulley like also available puller. If there is no puller can be sandwiched between two iron pole shaft. Floating pad wood or copper block, and then the upper end of the rotary shaft of the rotor, with a hammer so that the bearing disengaged Remove attention to safety during operation. Assembly, you can find an inner diameter slightly larger than the shaft outside diameter flat iron pipe set into the shaft so that the wall is just on top of the inner ring of the bearing can spout pad pieces of wood by hand hammer. Into the rotor positioning at the bearing sleeve. Note bearing inner circle and the shaft can not be too tight. If too tight, fine emery cloth available to play around the shaft surface, evenly polished look, the bearing sleeve into the general tightness can. Also between the bearing outer ring and end caps can not be too tight. Want to pay special attention in the assembly when the motor, not the end cap, bearing cap is mounted in the correct position, or do not grasp the good screw tightness and uniformity, will cause the motor rotor eccentric, caused a sweep chamber adverse operational failure.single ball bearing
