1) Wash the bearing with kerosene, press it into the bearing seat, fill the rollers of the outer ring of the bearing with Shell No. 3 lithium base grease to two-thirds full, and apply it evenly with clean hands. 2) The bearing is a cylindrical roller bearing with separable outer and inner sleeves, and the inner sleeve of the bearing should be installed on the rotating shaft and in place; 3) The bearing seat is installed on the casing , if there is a grease filling hole, align the position. Tighten the bearing seat with the fastening bolts coated with bolt anti-loosening glue; 4) The outer and inner eccentric blocks are installed on the rotating shaft and are in place. Install the retaining ring on the rotating shaft; 5) Tighten the fastening bolts of the fixed eccentric block, turn the adjustable eccentric block to the point of view before removal, and tighten the fastening bolts. After the above assembly is completed, the rotating shaft should have a certain axial series movement; 6) The protective covers at both ends of the upper oscillating motor should be fastened with screws. The damage of the bolted roller bearing manufacturer can be said to be equal to spalling, indentation, corrosion, cracks, wear, etc., which will be reflected in the vibration measurement of the roller bearing. Therefore, by using a special bearing vibration measuring instrument, the size of the vibration can be measured, and the specific situation of the abnormality can be inferred through the frequency distribution. The measured values ​​differ depending on the operating conditions of the bolted roller bearing or the position of the sensor device, so it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment standard. Maintenance of bolted roller bearings: thin oil is smooth: the advantage is that the internal conflict coefficient is small, so the cost of fighting the conflict is less, the thin oil has good fluidity, it is easy to enter the conflict surface of each smooth point, has excellent cooling effect, and can reduce the stickiness. The impurities attached to the surface of the conflict and the metal particles produced by grinding are carried away. The disadvantage is that the oil film cannot withstand large unit pressure, and the requirements for sealing are high. High-speed presses generally use large-flow thin oil to lubricate, which can take away the heat generated by each conflicting pair. Correct use of roller bearings can achieve fatigue life. But in the event of accidental early damage, it can no longer be used. Unlike fatigue life, this early damage is called a malfunction or accident. Most of them are caused by poor consideration of installation, use and lubrication, foreign matter intruding from the outside, or lack of research on shafts and bearing housings. The damaged state of the bearing, such as the abrasion of the ring rib of the roller bearing, may be caused by lack of lubricant, inappropriate grade, defective oil supply and discharge structure, foreign matter intrusion, bearing installation error or excessive deflection of the shaft. It may also be caused by a combination of the above reasons. Therefore, it is difficult to know the cause of the damage only by checking the bearing damage. However, if you fully understand the machine, working conditions and external structure of the bearing, clarify the situation before and after the failure, and analyze the damage of the bearing and various related reasons, you can prevent similar failures from happening again. The bolt roller bearing can guess what it looks like from its name. The outer ring of the bolt roller bearing adopts a full complement cylindrical roller bearing with a thicker outer ring wall, and the outer diameter of the roller has a cylindrical shape and an arc shape. , It can be designed to match the raceway surface according to the application. Using this outer ring, the roller can roll directly on the raceway, and can withstand heavier loads and impact loads. Its advantage is that the internal conflict coefficient is small, so it consumes less to overcome the conflict, the thin oil has good fluidity, and it is easy to enter the conflict surface of each smooth point, which has excellent effect, and can remove impurities adhering to the conflict surface and due to grinding. The resulting metal particles are taken away.
