How to deal with the heat phenomenon in the operation of the bolt roller bearing

What are the treatment methods for the heating phenomenon in the operation of the bolted roller bearing? Let's take a look. The precautions for the use of bearings are as follows: ⑴. Keep the bearings and their surroundings clean. Even small dust that cannot be seen by the eye can affect the roller bearing. Therefore, it is necessary to keep the surrounding clean so that dust does not penetrate into the bearing. 2. Use it carefully. If the bearing is subjected to severe impact during use, scars and indentations will be produced, which will become the cause of the accident. In severe cases, cracks and fractures may occur, so care must be taken. 3. Use appropriate operating tools. To prevent replacement with existing tools, appropriate tools must be used. Such as special sleeves, presses, etc. ⑷. Pay attention to the rust of the bearing. When handling INA bearings, sweat on your hands can cause rust. Be careful to operate with clean hands and wear gloves as much as possible. ⑸. Do not unpack the bearing before the preparation of the device is completed to avoid contamination. The life of the roller bearing is more sensitive to the load ratio to the rotational speed, so for the multi-stage drive shaft, if possible, the larger deceleration should be placed in the later stage; for the main shaft bearing, if possible, the external load action point should be properly allocated The distance between the bearing fulcrum and the bearing fulcrum tries to reduce the load of the spindle bearing, and try to transmit the load to the spindle bearing smoothly to prevent shock and vibration. And the selection of the matching is correct, and the installation accuracy of the bearing is good. The shaft parts of the machine tool, especially the main shaft, are generally assembled with bearings or sliding bearings, and rotate at a high speed, sometimes generating high heat. If this phenomenon is not removed in time, the bearing will be overheated, and the temperature of the corresponding parts of the machine tool will rise, resulting in thermal deformation. Burn out the bearing. The reasons for the heating of the roller bearing and its cleaning methods are shown in Table 1. The reason for the heating of the bolted roller bearing and its removal method Tightening method: adjust the belt to make the tightness appropriate 4. Reason: smoothness Poor method: choose the smooth material of the regular grade and clean it properly 5. Reason: low assembly quality Method: improve assembly quality and related wear parts 7. The axial force is too large: cleaning and adjusting the clearance of the sealing ring between 0.2 and 0.3 mm, correcting the diameter of the impeller balance hole and verifying the static balance value. 8. Bearing damage method: replace the roller bearing above This is the introduction of the treatment method for the heating phenomenon in the operation of the roller bearing, and I hope it will be helpful to everyone.
