Key knowledge of maintenance of cylindrical roller bearings

Writer： admin Time：2022-06-28

With the development of mechanization, cylindrical roller bearings play a key role in mechanical rotation, especially for bearings used in mold machinery. Mold machinery is a device that shapes objects and consists of many parts, among which the accuracy of bearing parts, The rotational speed, the stability and the fit with the angular contact ball of the molding part have a great influence on the performance of the mold machinery. The damage rate of cylindrical roller bearing parts of die machinery is relatively high, especially in blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, etc., the damage to cylindrical roller bearings is very high. big.

In order to ensure the performance of the mold machinery, improve the continuity of production, improve the efficiency and increase the benefits, it is necessary to increase the maintenance of the cylindrical roller bearing components, conduct frequent maintenance, and increase the frequency of maintenance. Moreover, bearing maintenance operators are required to have comprehensive knowledge of mechanical maintenance and maintenance. Let's talk about the key knowledge of the maintenance of cylindrical roller bearings:

1. Usually, the switching frequency should be reduced as much as possible when the machine is used. Too many switching devices will cause the cylindrical roller bearing components to wear too fast and affect the machining accuracy.

2. Lubricate the cylindrical roller bearing regularly to prolong its service time.

3. Fasteners such as cylindrical roller bearings are easy to loosen, and an inspection should be carried out every 2-3 days to ensure the working accuracy of the equipment.

4. The outer ring of the cylindrical roller bearing is prone to breakage, bending and gnawing, and it also needs to be checked and replaced regularly.

5. After using the cylindrical roller bearing for a long time, the cutting edge must be ground. After grinding, the cutting edge surface must be demagnetized, and it must not be magnetic, otherwise it is easy to cause material blockage.

The damage and loss of bearings are often encountered in the use of bearings. There are many forms of damage and loss of roller bearings, including corrosion, transportation damage, installation damage, lubrication loss, abrasive wear and fatigue, etc. In order to make the bearing as much as possible To maintain the performance of the bearing itself in a good state for a long time, it is necessary to regularly maintain, repair and deal with abnormal conditions of the bearing to ensure the reliability of operation. Maintenance is carried out on a regular basis based on the operating standards corresponding to the operating conditions of the machine. The content includes monitoring the running state of the bearing, supplementing or replacing the lubricant for the second-class bearing, and regular disassembly inspection.

Through the above content, we can have a detailed understanding of some knowledge about the maintenance of cylindrical roller bearings, which is very helpful for us to use it better in the future.
