[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0027] Reference Figure 1-Figure 5 A noise reduction flange bearing comprises a flange 1, an outer ring 2 and an inner ring 3. A first noise reduction component is provided inside the flange 1 and the outer ring 2, a second noise reduction component is provided on one side of the flange 1, a cavity is provided inside the outer ring 2 and the inner ring 3, and a plurality of rollers 4 are provided between the outer ring 2 and the inner ring 3;
[0028] The first noise reduction component includes an oil storage ring 5, which is located inside the inner ring 3. The interior of the outer ring 2 is provided with a second oil-absorbing cotton 8, a fixing ring 9, sound insulation cotton 10 and a buffer pad 11. The oil storage ring 5 and the second oil-absorbing cotton 8 lubricate the multiple rollers 4, and the fixing ring 9, sound insulation cotton 10 and buffer pad 11 reduce the noise of the multiple rollers 4.
[0029] Reference Figure 1-Figure 5 A plurality of through holes 7 are provided on one side of the oil storage ring 5, and the plurality of through holes 7 are arranged corresponding to the plurality of rollers 4. A first oil-absorbing cotton 6 is provided on one side of each through hole 7. The oil storage ring 5 is made of elastic material, and the second oil-absorbing cotton 8 is arranged on the side close to the plurality of rollers 4. The fixing ring 9 is fixedly installed inside the outer ring 2, and the sound insulation cotton 10 is located on the side of the fixing ring 9 away from the second oil-absorbing cotton 8. The buffer pad 11 is located between the inner wall of the outer ring 2 and the sound insulation cotton 10.
[0030] The noise generated by the roller 4 can be effectively reduced by the first noise reduction component. The specific operation method is as follows: first, the oil storage ring 5 is made of elastic material, and a certain amount of lubricating oil can be stored inside it. When the bearing is running, the lubricating oil in the oil storage ring 5 can flow to the roller 4 through a plurality of through holes 7 opened on one side. The first oil-absorbing cotton 6 arranged on one side of each through hole 7 can, on the one hand, absorb the lubricating oil in the oil storage ring 5 and control the outflow speed of the lubricating oil so that it can continuously and stably provide lubrication for the roller 4; on the other hand, the first oil-absorbing cotton 6 can filter impurities to prevent impurities from entering between the roller 4 and the raceway, affecting the lubrication effect and increasing wear. Since the second oil-absorbing cotton 8 located on the side of the outer ring 2 close to the roller 4 is in a saturated state, the lubricating oil can be evenly distributed on the surface of the roller 4, ensuring that the roller 4 is always in a good lubrication state during operation. Good lubrication can reduce the friction coefficient between the roller 4 and the raceway, thereby reducing the noise generated by friction;
[0031] The fixing ring 9 fixed inside the outer ring 2 can provide support for the sound insulation cotton 10 and the buffer pad 11. The sound insulation cotton 10 can absorb the noise sound waves generated when the roller 4 is running, and convert the sound energy into other forms of energy such as heat energy, thereby reducing the propagation of noise. The buffer pad 11 located between the inner wall of the outer ring 2 and the sound insulation cotton 10 can play a buffering role. When the roller 4 vibrates during operation, the buffer pad 11 can absorb and disperse the vibration energy, reduce the vibration transmission to the outer ring 2 and other components, and thus reduce the noise caused by vibration.
[0032] Through the synergistic effect of the oil storage ring 5 and the oil-absorbing cotton, continuous and stable lubrication is provided to the roller 4, and the friction coefficient between the roller 4 and the raceway is reduced, thereby effectively reducing the noise generated by friction. In various working environments, especially in noise-sensitive occasions, such as precision instruments and equipment, office places, etc., it can significantly improve the working environment and reduce the interference and adverse effects of noise on personnel. The sound insulation cotton 10 and the buffer pad 11 can absorb the noise waves generated by the operation of the roller 4, and convert the sound energy into other forms of energy, further reducing the propagation of noise. By reducing noise and vibration, the first noise reduction component makes the operation of the bearing more stable, which helps to improve the operating accuracy and stability of the equipment and reduce errors and failures caused by noise and vibration.
[0033] Reference Figure 1-Figure 5 The second noise reduction component includes a sound insulation cover 12, which is located on one side of the flange 1. A mounting groove 13 is provided on one side of the flange 1. Two fixing strips 14 are provided on one side of the mounting groove 13. Two mounting strips 15 are provided on the side of the sound insulation cover 12 close to the outer ring 2. The two mounting strips 15 are interference fit with the mounting groove 13. A sound insulation pad 16 is provided on one side of the flange 1, and the sound insulation pad 16 is made of elastic material.
[0034] The sound insulation cover 12 of the second noise reduction component is located on one side of the flange 1, which can effectively prevent the noise generated during the operation of the bearing from propagating to the outside. It forms a physical barrier to limit the noise to a certain range and reduce the impact of the noise on the surrounding environment. During installation, it is necessary to stagger the two mounting bars 15 and the two fixing bars 14, insert the two mounting bars 15 into the interior of the mounting groove 13, and then rotate a certain angle to clamp the sound insulation cover 12 at the bottom of the two fixing bars 14, so as to facilitate quick installation.
[0035] Working principle: First, the oil storage ring 5 is made of elastic material, and a certain amount of lubricating oil can be stored inside it. When the bearing is running, the lubricating oil in the oil storage ring 5 can flow to the roller 4 through a plurality of through holes 7 opened on one side. The first oil-absorbing cotton 6 arranged on one side of each through hole 7 can, on the one hand, absorb the lubricating oil in the oil storage ring 5 and control the outflow speed of the lubricating oil, so that it can continuously and stably provide lubrication for the roller 4; on the other hand, the first oil-absorbing cotton 6 can filter impurities to prevent impurities from entering between the roller 4 and the raceway, affecting the lubrication effect and increasing wear. Since the second oil-absorbing cotton 8 located on the side of the outer ring 2 close to the roller 4 is in a saturated state, the lubricating oil can be evenly distributed on the surface of the roller 4, ensuring that the roller 4 is always in a good lubrication state during operation. Good lubrication can reduce the friction coefficient between the roller 4 and the raceway, thereby reducing the noise generated by friction;
[0036] The fixing ring 9 fixed inside the outer ring 2 can provide support for the sound insulation cotton 10 and the buffer pad 11. The sound insulation cotton 10 can absorb the noise and sound waves generated by the operation of the roller 4 and convert the sound energy into other forms of energy such as heat energy, thereby reducing the propagation of noise. The buffer pad 11 located between the inner wall of the outer ring 2 and the sound insulation cotton 10 can play a buffering role. When the roller 4 vibrates during operation, the buffer pad 11 can absorb and disperse the vibration energy, reduce the vibration transmission to the outer ring 2 and other components, and thus reduce the noise caused by vibration.
[0037] The soundproof cover 12 of the second noise reduction component is located on one side of the flange 1, which can effectively prevent the noise generated during the operation of the bearing from propagating to the outside. It forms a physical barrier, limits the noise to a certain range, and reduces the impact of the noise on the surrounding environment.
[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
