Since the roller bearing is connected to the object for a long time, dust will enter the inside of the bearing, resulting in increased friction and thus increased noise, so this needs to be improved. First, the rubber ring 4 is fixed to the fixed screw groove 5 through the fixing screw 6, and then the roller bearing is fixed to the bearing seat. The rubber ring 4 can play a sealing role to a certain extent, preventing external impurities from entering the inside of the bearing and isolating the propagation path of some noise. Then the lubricating oil is added to the storage tank 7, and the sealing plug 8 seals the storage tank 7. Then the solenoid valve 12 is opened as needed, so that the drainage inclined plate 9 discharges the lubricating oil to the oil outlet 10, and then the roller body 2 and Adding lubricating oil between the inner shafts 3 of the bearing reduces friction and thus reduces noise. At the same time, the length of the L-shaped groove 11 is designed according to the needs of different bearings, so that the lubrication area is larger, thereby achieving the effect of noise reduction. Since the inner shaft 3 of the bearing is connected to external objects for a long time, wear will occur between them, which may cause damage to the inner shaft 3 of the bearing. Therefore, it is necessary to improve this. First, the assembly block 16 is moved to the outside of the sliding rod 14, and one end is fitted with the positioning block 15, and then the threaded rod 19 is fixed to the threaded groove 18.
