The shaft and bearing fit: cutting machine bearings how to repair the damaged

When quenching heating temperature, as the extension of austenitizing time, did not dissolve carbide to reduce the number of retained austenite, hardness, for a long time, to slow this trend. Repair the tube bank dryer bearing wear specific steps: auxiliary repair technology is mainly used in wear size are relatively uniform, equipment parts under the condition of running speed is not high, in order to meet the normal operation of the equipment; The preparation work before construction, such as tools, materials, and need to change the spare parts ( The axial adjustment ring, remove the installation tools, oxygen - Acetylene gas cutting tools, micrometer, gasket, anhydrous ethanol, harmonic board) And so on; Repair, completes the personnel security measures; Check the shaft end before remove the bearing wear condition, the axial and radial wear ties are measured in detail. Prevention of moving cone imbalances, bearing use note bearing is precision components, but no matter how high performance bearing, use if use undeserved, will not get the desired effect. Failure cause analysis: the study found that the main shaft pine knife sword out of action with manipulator moves not harmonious, the specific reason is limit switch installed in pressurization of the end of the cylinder, the cylinder piston action in place, the pressure cylinder piston is not in place in time, resulting in the clamping structure of the manipulator is not completely let go when the sword out, seriously damaged the tie rod ball and tighten screw. The distance between the front and rear bearing has reached the mm, with the same level compared Mercedes sedan type C grade, length and width and height of the new cars and bearing has the advantage of, in terms of power, the new car models are paired with. Process: loose bearing sleeve joint bolt, next to the lift bearing sleeve in, working procedure, loosen the bolt bearing joint surface, will have laid the rubber bearings in the specified location. For the requirement of rolling plate edge, rolling strip shape adjustment result is each backup roll on mileage from both ends of the first set of bearing load, commonly known as 'the phenomenon of cat ears'. & emsp; & emsp; To prevent and avoid change low voltage side circuit breaker box can't automatic protective tripping fault happened, & amp; emsp; & emsp; （ 5) Prevent other type unit caused the collapse. Check the pump shaft seal ring, if badly worn should be replaced a new parts, in TWINCAMILQ - Series bearings use ball bearings, able to withstand a load of larger, higher speed. When the bearing temperature is high, should first solve the problem from the following several aspects: amount to is not appropriate, lubricating grease too little or too much work shall, in accordance with the requirements for bearing box on a regular basis. Sauvy carbon nanometer polymer repair technology is how to realize the rapid repair concrete operating process is as follows: surface baked oil: oil using acetylene oxygen for baking, operation time control between the minute to minute; Surface polishing: use the rough grinding polishing machine will surface, clean, improve sauvy carbon nano polymer SDH cohesive force. In addition, select the appropriate bearing size is important, or face premature bearing wear and bearing the risk of failure, of course, should also be listening to the advice of equipment and manufacturers.
