Self-aligning ball bearings are widely used in various types of mechanical equipment due to their unique design and excellent performance. However, in actual application, bearing overheating has become one of its common faults. Overheating of bearings not only affects their performance, but may also cause equipment damage and reduced production efficiency, causing unnecessary losses to enterprises.
Overheating is one of the main causes of failure of self-aligning ball bearings. When the bearing temperature exceeds the design range, the performance of lubricating oil or grease will significantly decrease, the lubrication effect will weaken, and friction and wear will increase. This phenomenon directly leads to a significant shortening of the bearing service life, increases the frequency of maintenance and replacement, and thus increases the operation and maintenance costs of the enterprise. Therefore, it is crucial to control the temperature of the bearing to extend its service life and reduce maintenance costs.
In high temperature environments, the lubricant of self-aligning ball bearings is prone to degradation and loses its original lubrication and protection. The degradation of the lubricant not only reduces the lubrication effect, but may also form precipitates or colloidal substances, further blocking the lubrication channel. This phenomenon leads to increased friction inside the bearing, further increase in temperature, forming a vicious cycle, and ultimately leading to the failure of the bearing. Therefore, selecting a suitable lubricant and regularly checking its status are key measures to ensure the normal operation of the bearing.
When a self-aligning ball bearing overheats, the material may expand thermally, causing the bearing clearance to increase or deform. This change will directly affect the running accuracy of the bearing, causing increased vibration and noise in the equipment, thereby affecting the overall performance. Especially in application scenarios with high precision requirements, the loss of precision caused by overheating may result in substandard product quality, which in turn damages the company's reputation. Therefore, ensuring that the bearing operates within the appropriate temperature range is critical to maintaining product quality.
In addition, overheating will also increase the friction of the internal components of the self-aligning ball bearing, causing significant vibration and noise. Excessive vibration not only affects the stability of the equipment, but may also cause damage to other components. Long-term vibration and noise not only have an adverse effect on the operator's working environment, but may even affect the safety of the equipment. Therefore, companies should fully consider the heat dissipation performance of the bearing when designing and selecting to reduce the impact of vibration and noise on equipment and personnel.
In high temperature environments, the material properties of self-aligning ball bearings will also degrade, especially the hardness and strength of steel will decrease. This performance degradation will reduce the bearing's load-bearing capacity and increase the risk of fatigue damage and plastic deformation. This may not only lead to early failure of the bearing, but also cause serious failure of the equipment. Therefore, selecting high temperature resistant materials and optimizing bearing design are important strategies to improve their durability.
