Motor bearing is broken how do I take?

Motor bearing is bad, how to take down in ah, like the appearance of a tight, dare not hard, also does not have the central force, how to do ah, small make up teach you. Firstly, opened the back cover, with a mark stroke shaft and motor shell, with shaft encoder activity base, encoder movable activity base location ring and motor shell positioning line, a total of three. Second, loosen and motor encoder base two fixed screw, turning the encoder and the axis connecting screws, about conical connection shaft, because of tighter cohesion, available at hammer insert encoder and motor side of thick screwdriver ( Because of the greater the screwdriver into the deep) Can put out the entire encoder, note the location of the screwdriver inserted, don't spoil the encoder, tapping time don't too hard, be careful not to let the encoder to the public, will be broken. About with the stigma of screws is first to unscrew the head screw, then hand them out. After three, remove the encoder, you can press the two ordinary motor to remove the motor end cover, is very simple, first remove the pulley, and then spin off on both sides of the four screw fixation, the average with a hammer to tap end cover can be removed, the lid back cover is able to use the method of impact front axle end face out a big seam to, pay attention to: the rotor with strong magnetic, not very hard to take not to come out, then can the motor fixed on the vise body, then will be able to use the hand to pull out the inside of the rotor, don't stop, make an effort to continue to pull out, otherwise you will be sucked through again the bruised your finger, it is not worth. Some users due to don't understand the internal structure of servo motor, without dismantling the encoder directly with a hammer to knock the motor, the bearing was replaced, but the motor is discarded, because there is a glass in the encoder do light code disc, with a hammer knock fragment, this is particularly want provoked attention. Four, in ramallah the damaged bearing, bearing and change the new model with the size. Five, the pack back to the motor stator, according to the initial installed motor end cover, put back the pulley six, according to the marker of the original positioning feeds back to the encoder.
