There are two types of outer ball cylindrical roller bearings, which are widely used due to their particularity and the incomparable advantages of other bearings. So what are the damage forms of thin-walled cross rollers? The following is a detailed introduction. 1. Wear and peeling of the outer ball cylindrical roller bearing and the inner and outer ring raceways: This will cause the radial clearance and axial clearance of the thin-walled outer ball cylindrical roller bearing to increase, and the outer ball cylindrical roller bearing will emit light during operation. Noise and heat, and change the correct working position of its mating shaft, there is vibration. The initial stage of surface fatigue peeling is the appearance of pockmarks on the surface, which develops into flake-like surface peeling. Both the rolling elements of the bearing and the raceway surfaces of the inner and outer rings are subjected to periodic pulsating loads, resulting in cyclically changing contact stress. When the number of stress cycles reaches a certain number, fatigue spalling occurs on the rolling elements or the working surfaces of the inner and outer ring raceways. This fatigue is exacerbated if the bearing is overloaded. In addition, if the bearing is not installed correctly and the shaft is bent, the phenomenon of raceway peeling will also occur. Fatigue spalling of the bearing raceway will reduce the running accuracy of the shaft, causing vibration and noise. 2. The mating surfaces of the inner and outer rings are worn: this is because the inner and outer rings of the thin-walled outer ball cylindrical roller bearing are not properly assembled with the shaft and the housing hole, which destroys the matching relationship between the bearing and the housing, the bearing and the shaft, and further accelerates the bearing. The wear of itself and the matching surface of the shaft or housing it is matched with (commonly known as the inner ring or the outer ring). 3. Wear and looseness of the isolation ring: The isolation ring and the rolling elements (balls, rollers, etc.) rub against each other during work. If the lubrication is poor, the wear will be accelerated. After the isolation ring is worn, the rolling elements are loose, and in severe cases, the isolation ring will fall apart and the rolling elements will fall off. 4. Burns: If the lubrication is poor or the lubricating oil does not meet the requirements, and the clearance of the thin-walled cross-roller bearing is adjusted too small, the bearing will heat up rapidly during operation, and the working surface will be annealed due to high temperature. When observed externally, it can be found that the color of the working surface of the thin-walled outer ball cylindrical roller bearing changes. 5. Plastic deformation: If uneven pits appear on the contact surface between the raceway and the roller, it means that the thin-walled outer ball cylindrical roller bearing has plastic deformation. The reason is that under the action of a large static load or impact load, the local stress on the working surface exceeds the yield limit of the material. This situation generally occurs on bearings that rotate at low speeds. 6. Cracks in the seat ring and fragmentation of the cage: The reason for the cracks in the seat ring of the thin-walled outer ball cylindrical roller bearing may be that the bearing is too tight, the outer or inner ring of the bearing is loose, and the inclusion of the thin-walled crossed roller bearing Deformation, poor surface finish of mounted thin-walled crossed roller bearings, etc. The reasons for the fracture of the cage are insufficient lubrication, broken rolling elements, and skewed races. Serious wear of the raceway of the raceway may be caused by foreign objects falling into the raceway, insufficient lubricating oil, etc.
