After long-term use, the inner and outer rings of the bearings will undergo a series of complex wear processes, and their wear mechanisms are affected by a combination of multiple factors.
First, fatigue wear is a common mechanism. During the operation of the bearing, the inner and outer rings are constantly subjected to alternating loads, and the surface material will produce tiny cracks due to repeated stress. Over time, these cracks gradually expand and connect, eventually leading to material peeling and wear. For example, under high speed and heavy load conditions, this fatigue wear will be more obvious.
Secondly, adhesive wear should not be ignored. When the lubrication between the inner and outer rings of the bearings and the rolling elements is insufficient or the lubricating film is broken, the metal surfaces are in direct contact, and adhesion and cold welding occur. In relative motion, the adhesion site is torn to form tiny metal particles, which further aggravates wear. This is easy to occur under low speed, high temperature or poor lubrication.
In addition, abrasive wear can also cause damage to the inner and outer rings of the bearings. Hard particles such as dust and impurities from the outside enter the bearing, and under the rolling action of the rolling elements, scratches and grooves will be formed on the inner and outer ring surfaces. Even tiny particles will cause severe wear under long-term action.
Corrosion wear is also an influencing factor. Moisture, chemicals, etc. in the environment may cause corrosion on the surface of the Processing Of Bearing Inner And Outer Rings. Corrosion products will destroy the integrity of the surface, reduce its strength and wear resistance, and thus accelerate the wear process.
To understand the wear mechanism more intuitively, we can take the bearing in an industrial fan as an example. In long-term continuous operation, due to the vibration and unbalanced load of the fan, the Processing Of Bearing Inner And Outer Rings are subjected to frequent alternating stresses. At the same time, due to the failure of the lubrication system, insufficient lubrication may cause local adhesive wear. In addition, there are certain dust particles in the environment where the fan is located, which causes abrasive wear. Over time, these wear mechanisms interact with each other, making the surface of the Processing Of Bearing Inner And Outer Rings gradually rough, pitting and peeling, and ultimately affecting the normal operation of the fan.
In addition, micro-motion wear is also a common phenomenon. If there is a slight relative movement at the bearing installation, micro-motion wear will occur. Although this wear is subtle, long-term accumulation will also have an adverse effect on the performance of the bearing.
In summary, the wear mechanism of Processing Of Bearing Inner And Outer Rings after long-term use is the result of multiple factors. In order to reduce wear and extend the service life of the bearing, it is necessary to reasonably select materials, optimize the design, ensure good lubrication and a clean working environment, etc.
