If there are bumps, rust layers, wear debris, sand, dust and mud on the surface of the bearing assembly and the parts that match it, firstly, the bearing device is difficult and the assembly position is incorrect; Wear and tear on the working surface of the bolt roller bearing affects the quality of the assembly. Therefore, before installation, the surface of the journal, the surface of the housing hole of the bearing housing, the end face of the shoulder, and the matching surface of the connecting parts such as bushings, washers, end caps, etc., should be carefully inspected. If there is a rust layer, it can be removed with a fine file, polished with a fine emery cloth, and the attachments on the surface of the bearing assembly and its connecting parts should also be removed. Precautions for the use of bearings: INA bearings are delicate parts, and their use must be handled with caution. No matter how high-performance bearings are used, if used improperly, bolt roller bearing manufacturers will not get the expected high performance. The precautions for the use of bearings are as follows: ⑴. Keep the bearings and their surroundings clean. Even small dust that is invisible to the eye can affect the bolted roller bearing. Therefore, it is necessary to keep the surrounding clean so that dust does not penetrate into the bearing. ⑵. Be careful to use it. 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 corrosion 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 bolted roller bearing is more sensitive to the load ratio to the rotational speed, so for the multi-stage transmission shaft, if possible, the larger deceleration should be placed in the later stage; for the main shaft bearing, if possible, the external load should be properly distributed. The interval between the point and the bearing fulcrum tries to reduce the load of the main shaft bearing, and tries to transmit the load to the main shaft bearing smoothly to prevent shock and vibration. The clearance and fit are selected correctly, and the bearing installation accuracy 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 bolted roller bearing and its removal methods are shown in Table 1. Reasons for bearing heating and how to remove it : Adjust the belt to make the tightness appropriate 4. Reason: Smoothness Poor method: Use regular grades of smooth material and clean it properly 5. Reason: Low assembly quality Method: Improve assembly quality Wearing parts 7. The axial force is too large: cleaning and adjusting the sealing ring clearance 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: changing the bolt roller bearing technical consultation , please call the Speika Bearing Technology Section
