In mechanical equipment, bearings are one of the important parts and bear the important functions of support and rotation. However, as the running time of the equipment increases, the problem of bearing heating gradually becomes apparent, which adversely affects the normal operation of the equipment.

Cause of fever

When the bearing is working, it is easy to generate heat due to factors such as friction and poor lubrication. The main reasons are as follows:

Insufficient lubrication: Bearings require good lubrication conditions when working to reduce friction and wear. If there is insufficient lubricating oil or grease, or if the lubricating material used is inappropriate, the friction in the bearing will increase, resulting in heat generation.

Overload operation: Bearing operation under overload or overload conditions will cause friction to increase, causing the bearing to heat up.

Poor assembly: If the bearing is not installed in place or there is a deviation during installation, it will cause the bearing to operate abnormally, increase friction, and generate heat.

Bearing damage: When the bearing is damaged or severely worn, friction increases, which can lead to heat generation.

The ambient temperature is too high: The ambient temperature is too high, which will increase the temperature of the outer and inner rings of the bearing, causing the bearing to heat up.

Solution

To solve the problem of bearing heating, the following solutions can be taken:

Reasonable selection of lubricating materials: Select appropriate lubricating oil or grease according to the bearing working conditions and environmental requirements, and ensure regular replacement and replenishment.

Control the load: During the design and use of the equipment, reasonably control the load to avoid overload or operation under overload conditions.

Optimize bearing installation: During the bearing installation process, ensure that the bearings are installed correctly and in place, reduce deviations, and ensure normal operation of the bearings.

Regular inspection and maintenance: Regularly inspect and maintain the bearings, and deal with problems in a timely manner to avoid heating caused by bearing damage.

Improve the working environment: Reasonably design and improve the equipment working environment, control the ambient temperature, and avoid bearing heating problems caused by high temperatures.

Use high-quality bearings: Choose bearing products with reliable quality to reduce heating caused by bearing quality problems.

To sum up, bearing heating problem is one of the important factors affecting the normal operation of equipment, which needs to be paid attention to and effective measures should be taken to solve it. By properly selecting lubricating materials, controlling loads, optimizing bearing installation, regular inspection and maintenance, improving the working environment and using high-quality bearings, we can effectively reduce bearing heating problems and ensure the normal operation of the equipment.
