Description

Technical Field

[0001] The invention relates to the technical field of bearing seats, in particular to a waterproof and dustproof bearing seat. Background Art

[0002] Bearings are indispensable precision components in mechanical systems. Their main function is to support rotating shafts and reduce frictional resistance during movement, thereby ensuring efficient and smooth operation of mechanical equipment. According to the working principle and structural characteristics, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings achieve low-friction movement by rolling elements (such as balls and rollers) between inner and outer rings. They have the advantages of strong load-bearing capacity, low friction coefficient, and long service life. They are widely used in high-speed and high-precision occasions. Sliding bearings rely on sliding friction to work. They are usually composed of bearings and journals and are suitable for low-speed, heavy-load or high-impact load conditions. The performance of bearings directly affects the reliability, efficiency and life of mechanical equipment. Therefore, the design and manufacture of bearings need to comprehensively consider factors such as material selection, lubrication method, sealing structure, and working conditions; As an important supporting component of the bearing, the bearing seat will have a serious negative impact on the operation of the bearing and the entire mechanical system if it does not have dustproof and waterproof functions. In a dusty environment, dust and particulate matter can easily enter the bearing through the gap of the bearing seat, causing the friction between the rolling element and the raceway to increase, thereby accelerating the wear of the bearing and reducing its service life. At the same time, the accumulation of dust may also block the lubrication channel, affecting the lubrication effect and further exacerbating the damage to the bearing. In humid or water-contact conditions, water intrusion into the bearing seat will cause the grease emulsification to fail and lose its lubrication effect, which will cause the bearing to rust and corrode. Rust will not only destroy the finish of the bearing surface, but also increase the bearing clearance, affect the rotation accuracy, and even cause vibration and noise problems. In addition, the intrusion of water and impurities may also change the stress distribution inside the bearing, leading to early fatigue failure of the bearing, and in severe cases may even cause equipment shutdown or safety accidents.
