How to deal with the phenomenon found in the running of roller bearing

With this type of outer ring, the roller can directly migrate and transform on the raceway, and can withstand heavier and striking loads. Despite having a small cross-section, the bearing still has a higher load capacity. Therefore, it is especially suitable for places with restricted radial space.

When the workpiece of Changzhou roller bearing manufacturer is severely overheated, coarse crystal grains will occur, and at the same time, the amount of 8 iron cables in the steel will increase, which is easy to cause deterioration of the hot working performance of the workpiece. Then, how should we prevent the bearing workpiece from overheating?

Strictly control the casting heating temperature and heating and heat preservation of the stainless steel box and flange parts of lcrl8Ni9]ri to prevent the workpiece from overheating and causing the workpiece to have the defect of coarse grains.

In the forging production of workpieces, if the casting ratio is too small, the final forging temperature is too high, and the defects of coarse-grain structure are easy to appear. The casting ratio of the workpiece should be suitable and sufficient, and the final forging temperature should be moderate like Changzhou Fangyi bearing.

If there are bumps, rust layers, wear debris, sand, dust, and soil on the assembly surface of the bearing and its mating parts, the bearing device is difficult to form and the assembly position is incorrect; the other is that these attachments constitute abrasive and easy The working appearance of the abrasion roller bearing affects the assembly quality. Therefore, the appearance of the journal, the housing hole of the bearing housing, the end face of the shoulder, and the matching appearance of the connecting parts such as bushings, washers, end caps, etc. should be carefully inspected before the installation. If there is a rust layer, it can be filed off with a fine file and polished with a fine emery cloth. At the same time, the surface of the bearing assembly and the attachments on the connecting parts should be cleaned.

Precautions for the use of bearings: INA bearings are delicate parts, and their use must be carefully stopped accordingly. The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thicker outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, which 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 shock loads.

No matter how high-performance bearings are used, if they are used improperly, the expected high performance will not be obtained. Precautions for the use of bearings are as follows:

⑴. Keep the bearing and its surroundings clean. The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thicker outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, which 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 shock loads. The composite roller bearing is used as the connection part of the composite roller and the machine equipment. Usually the head of the shaft head is designed with a chamfer for easy installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded to the connection with a round hole. Then assemble the connecting board and the equipment on the board. Even small dust invisible to the eyes will affect the roller bearing. Therefore, it is necessary to keep the surrounding area clean to prevent dust from invading the bearing.

⑵. Use it carefully and carefully. In use, a strong impact on the bearing will cause scars and indentations, which will be the cause of the accident. In severe cases, cracks and breaks may occur, so be careful.

⑶. Use appropriate operating tools. To prevent substitution 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 become a cause of rust. Pay attention to the operation with clean hands, it is best to wear gloves as much as possible.

⑸. Before the preparation of the device is completed, do not unpack the bearing to avoid contamination.

The cause of bearing heating and its cleaning method

1. Reason: low bearing accuracy. Method: select bearings with regular accuracy grades

2. Reason: the spindle is bent or the box hole is not concentric. Method: repair the spindle or box

3. Reason: The belt is too tight. Method: Adjust the belt to make it tight.

4. Reason: poor smoothness method: choose smooth materials of regular grades and clean them properly

5. Reason: Low assembly quality Method: Improve assembly quality

6. Reason: The inner and outer shell running circle method of the bearing: change the bearing and related wear parts

7. Too much axial force: cleaning and adjusting the gap between the seal ring and 0.2～0.3mm, correcting the diameter of the equalizing hole of the impeller and checking the static equalization value

8. Bearing damage method: change the roller bearing
