Motor bearing wear reason and repair plan

The power source of the motor, as with all electrical or mechanical, its role is largely applied mechanical energy into electrical energy. The use of long history, making the motor becomes the indispensable important equipment in industrial consumption. In the face of such devices, its bearing wear is also very common, common a few kinds: 1. Smooth bearing too much fat, its setting out, to the winding, winding corrosion. 2. Bearing device or device belt wheel is not correct, the bearing force inside and outside the circle of loaded askew, the rotation is not sensitive, damage of bearing heating. 3. Bearing roller ball, the inner and outer ring ball bracket severe wear and gold flake, form the motor sound, the electric JiSao boring and burned. 4. Motor axial channeling, different size between bearing cover and coat of the bearing. Motor, the rotor heat shrinkage elongation, bearing heating. 5. The motor end cover was not good, check the mouth not to rely on tight, or uneven bearing cover, make the ball wide orbits and fever. 6. Protection is not good, bearing in water or dust, the damage of bearing is not smooth and good. Usual, maintenance technology from the off-line repair carried out to the on-line maintenance, adopt what kind of technology is more appropriate, continuously is a trouble problem for a long time, and the present several kind of repair, common the following kinds: overall demolition change set with non-standard sets of repair welding, grinding, sauvy carbon nanotubes in polymer materials. Remove the change to change the new parts is the conventional way to repair, keeping regular consumable parts and equipment management measures in the wrist. When removing bento, maintenance are usually using this method. Low set non-standard sets of Mosaic non-standard sets of emergency repair measures is also a kind of common wrist. Biggest weakness is the machining accuracy is not high, and the wear parts of the contact area is finite, easy to form secondary wear and greatly increase the safe hidden trouble of consumption low repair repair welding repair welding grinding machining is one of the most common way in traditional technology, its characteristic is to repair precision is high. Its defect is easily in the process of repair of axial stress concentration or form the shaft bending deformation; Repair welding technology to prevent the problem of thermal stress and formation of shaft using present in the process of crack and fracture risk, increase consumption safe hidden trouble. Low carbon nanotubes sauvy polymer materials is based on the above sauvy carbon nano polymer materials to stop the images at the site. Are using sauvy carbon nano polymer materials, first is sauvy polymer materials with excellent mechanical properties, carbon nanotubes materials after curing meet the car, milling, planing, grinding processing request, so in dealing with the equipment problem, can according to equipment wear conditions and the conditions at the site to make a reasonable and effective technical plan. Second, no matter what repair plan, ensure the repaired concentricity with size and appearance is sauvy carbon nano polymer application technology of the key elements. Sauvy carbon nano polymer materials field repair of the motor bearing a step 1. Appearance baked oil disposal; 2. Exterior burnish disposal; 3. Distribution sauvy carbon nano polymer materials SD7101H and apply to the repair parts appearance; 4. Device sauvy tooling; 5. Heat curing; 6. Remove the tooling data after curing; 7. Measurement of size and antipyretic bearing 8. Hot charging bearing assembly can start up after the end of operation.
