Motor bearing is an important part of motor equipment, and its performance directly affects the running accuracy, stability and life of the motor. The correct disassembly and installation of motor bearings is of great significance to ensure the normal operation and prolong the service life of the motor. This paper will discuss the disassembly and installation skills of motor bearings from the aspects of disassembly and installation skills, precautions and so on.
Before disassembling the motor bearing, it is necessary to prepare the corresponding tools and materials, including pullers, hammers, wrenches, lubricants, etc. At the same time, it is necessary to determine the type and model of the bearing in order to select the correct disassembly method.
Bearings cleaning: Before disassembly, bearings need to be cleaned to remove dust and dirt on the surface. You can use a solvent such as cleaning agent or gasoline for cleaning, and dry with a clean cloth after cleaning.
Disassemble the inner ring: For the inner ring disassembly, you can use the puller to disassemble. The claw head of the puller is stuck in the groove of the inner ring of the bearing, and then gently hit the other end of the puller with a hammer to gradually loosen the inner ring. If you do not have a puller, you can also use a tool such as a wrench or screwdriver to remove it.
Remove the outer ring: For the outer ring disassembly, you can use the push or knock method to remove. Pushing method is to apply a certain pressure on the bearing outer ring, so that it produces a trace deformation, so as to loosen the outer ring. The tapping method is to gently tap the edge of the bearing outer ring with a hammer to gradually loosen the outer ring. It should be noted that the force should be uniform when tapping to avoid damaging the bearing.
Note: During the disassembly process, keep the bearing clean and dry to avoid impurities such as dust and water entering the bearing interior. At the same time, avoid using too much force to disassemble the bearing, so as not to damage the bearing or bearing seat.
Before installing motor bearings, it is also necessary to prepare the corresponding tools and materials, including bearings, lubricants, wrenches, etc. At the same time, it is necessary to determine the type and model of the bearing in order to choose the correct installation method.
Bearings cleaning: Before installation, bearings need to be cleaned to remove dust and dirt on the surface. You can use a solvent such as cleaning agent or gasoline for cleaning, and dry with a clean cloth after cleaning.
Install the inner ring: For the inner ring installation, the bearing can be placed on the journal first, and then the inner ring can be evenly pressed into place with your finger or a soft metal tool. If the bearing inner ring is large or the journal is thin, the hot mounting method can be used for installation. The bearing inner ring is heated to a certain temperature and quickly fitted on the journal, and then evenly pressed into place with a tool.
Install the outer ring: For the outer ring installation, the bearing can be placed in the bearing seat first, and then the outer ring can be evenly pressed into place with your finger or a soft metal tool. If the bearing outer ring is large or the bearing seat is thin, it can be installed using the hot loading method. The bearing outer ring is heated to a certain temperature and quickly fitted on the bearing seat, and then it is evenly pressed into place with a tool.
Note: During the installation process, keep the bearing clean and dry to avoid impurities such as dust and water entering the bearing interior. At the same time, avoid using too much force to install the bearing, so as not to damage the bearing or bearing seat. In addition, pay attention to the selection of the correct lubricant and lubrication method to ensure the normal operation of the bearing and extend the service life.
The disassembly and installation skills of motor bearings are of great significance to ensure the normal operation and prolong the service life of the motor. During the disassembly and installation process, it is necessary to pay attention to keep the bearings clean and dry, and avoid using too much force to disassemble or install the bearings. At the same time, it is necessary to choose the correct disassembly and installation method and the appropriate lubricant and lubrication method according to the specific situation. Only by mastering the correct disassembly and installation skills can we better maintain the normal operation of the motor equipment.
