[0033] Embodiment 3
[0034] Reference Figure 1-Figure 5As shown, a first annular plate 1002 is installed at the bottom end of the bearing outer ring 1001, and a second annular plate 1007 is installed at the upper end of the bearing outer ring 1001, a pair of oil inlet pipes 1008 are installed at the upper end of the second annular plate 1007, and a plugging cover 1009 is inserted inside the upper ends of the pair of oil inlet pipes 1008. An oil filling port 1010 is provided at the upper end of the bearing outer ring 1001 near the oil inlet pipe 1008. The bearing outer ring 1001 is connected to the oil storage ring 2001 through the oil filling port 1010. By setting the first annular plate 1002 and the second annular plate 1007, it is convenient for the shaft to pass through the first annular plate 1002. 002, the bearing inner ring 1003 and the second annular plate 1007. At the same time, the first annular plate 1002 and the second annular plate 1007 can block the gap between the bearing outer ring 1001 and the bearing inner ring 1003. By setting the oil inlet pipe 1008, it is convenient for lubricating oil to enter. By setting the sealing cover 1009, the oil inlet end of the oil inlet pipe 1008 is blocked when no oil is injected. By setting the oil injection port 1010, and the bearing outer ring 1001 is connected with the oil storage ring 2001 through the oil injection port 1010, it is convenient for lubricating oil to enter the interior of the oil storage ring 2001 through the oil injection port 1010.
[0035] Specifically, the working principle of this rolling bearing is as follows: when in use, the sealing cover 1009 is opened and the oil inlet pipe 1008 is filled with oil, so that the lubricating oil can enter the interior of the oil storage ring 2001 through the oil inlet pipe 1008 and the oil filling port 1010, and the oil outlet pipe 2002 is arranged on the outside of the oil storage ring 2001, so that the lubricating oil inside the oil storage cavity can contact with the oil storage cotton 2003 through the oil outlet pipe 2002, and at the same time, the arc-shaped side of the oil storage cotton 2003 is in contact with the ball 1006, so that the lubricating oil can be evenly applied to the outside of several balls 1006, so that the contact area between the ball 1006 and the raceway and other components can be reduced by the lubricating oil, thereby reducing wear and extending the life of the rolling bearing. At the same time, the rolling bearing can also be cooled to avoid overheating. When the ball 1006 is worn out after long-term use, it will cause the ball 1006 to contact the roller 1006. The gap at the fitting place of the components such as the track becomes larger. Through the coordinated use of the rubber strip 3005 and the extrusion strip 3004, when the ball 1006 is not worn, the outside of the ball 1006 will be pressed and fitted with the rubber strip 3005, so that the rubber strip 3005 and the extrusion strip 3004 will shrink to the inside of the cavity 3002 under the elastic action of the compression spring 3006. When the ball 1006 is worn and no longer fits with the rubber strip 3005, the rubber strip 3005 and the extrusion strip 3004 will move stably on the slide bar 3003 under the elastic force of the compression spring 3006, so that the rubber strip 3005 and the extrusion strip 3004 slowly extend from the cavity 3002 according to the gap between them and the ball 1006. At the same time, because one end of the rubber strip 3005 is in contact with the ball 1006, noise reduction and shock absorption are achieved at the fitting place of the rubber strip 3005 and the ball 1006.
[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
