[0002] Slewing bearings, also known as turntable bearings, are large bearings with special structures that can simultaneously withstand large axial loads, radial loads, overturning moments and other combined loads, and integrate multiple functions such as support, rotation, transmission, and fixation. Slewing bearings are usually composed of inner rings, outer rings, sealing rings, rolling elements, and isolation blocks, so that they can support mechanical rotating bodies, reduce their friction coefficients during movement, and ensure their rotation accuracy, effectively reducing the wear of equipment during angle adjustment.

[0003] However, the existing slewing bearings still have some defects during use: first, since the inner and outer rings of the slewing bearings are in a movable state, the slewing bearings are prone to shaking during use, thereby affecting the normal operation of the slewing bearings; second, due to the working characteristics of the slewing bearings, they need to have good lubrication properties to reduce the friction inside the bearings. Therefore, the existing slewing bearings are often filled with lubricating oil.

[0058] See also Figure 2-Figure 5 , Figure 13-Figure 16 , a limiting mechanism 4 is provided in the inner ring 12 between the two movable grooves, and the two ends of the limiting cavity are respectively connected with the two movable grooves, and the middle part of the limiting cavity is connected with the connecting channel. The number of the limiting cavities is six, and the six limiting cavities are evenly arranged around the bearing mechanism 1. The inner ring 12 is connected to the limiting mechanism 4 through the limiting cavity, which is used to promote the lubricating oil to be evenly distributed in the circumferential direction in the connecting channel. The limiting mechanism 4 is composed of a limiting ring 41 and a rotating component 5. The upper half and the lower half of the inner wall of the limiting cavity are fixedly sleeved with the limiting ring 41.

In the process of the isolation block 15 moving along the connecting channel, the push block 6 can not only drive the lubricating oil to move along the connecting channel, but also evenly spread the lubricating oil on the wall surface of the inner groove, thereby realizing the uniform distribution of the lubricating oil in the connecting channel.

[0061] See also Figure 1-Figure 2 , Figure 4 , Figure 6-Figure 7 , Figure 10-11 , an oil inlet pipe 7, an oil inlet pipe 7 is fixedly sleeved in the middle of the outer ring 11, and one end of the oil inlet pipe 7 is connected to the outer groove of the outer ring 11, and the other end of the oil inlet pipe 7 can be connected to the oil injection device, so that the oil injection device can inject lubricating oil into the outer groove area of ​​the outer ring 11 to achieve lubrication of the rolling elements 14 and the isolation blocks 15 in the connecting channel. The number of oil inlet pipes 7 is six, and the six oil inlet pipes 7 are alternately arranged with the six groups of fixing mechanisms 2, which effectively ensures that the charging and suction operations of the fixing mechanisms 2 and the injection operations of the oil inlet pipe 7 do not interfere with each other.

[0062] The working principle of the method of the present invention is as follows:

[0063] When the bearing mechanism 1 is installed, after the inner ring 12 is installed inside the outer ring 11, the fixing mechanism 2 is connected to the air pump, and the two fixing mechanisms 2 in the same group are connected to different air pumps, and then the opening and closing valve of the fixing pipe 21 is opened, and the air pump is used to inflate the fixing cavity of the fixing pipe 21. The two fixing pipes 21 in a group of fixing mechanisms 2 are synchronously filled with the same amount of gas, so that one end of the fixing rod 22 extends outward and conflicts with the movable groove of the inner ring 12. At this time, the overall length of the fixing mechanism 2 is adjusted and the outer ring 11 and the inner ring 12 are effectively connected, so that the outer ring 1 1. A triangular structure is formed between the inner ring 12 and the fixing mechanism 2, which effectively improves the stability between the outer ring 11 and the inner ring 12, reduces the shaking between the two, and ensures the normal operation of the slewing bearing. In addition, since the fixing mechanism 2 is arranged in a ring shape between the outer ring 11 and the inner ring 12, the fixing mechanism 2 can effectively block the sealing ring 13. After the bearing mechanism 1 has been used for a long time, when the sealing ring 13 falls off under the influence of a large radial load and overturning moment, it can be stuck by the fixing mechanism 2 and collected in time, which effectively improves the subsequent reuse rate of the sealing ring 13.

[0064] When the bearing mechanism 1 is injected with lubricating oil, the oil inlet pipe 7 is first connected to the oil injection device, so that the oil injection device injects a certain amount of lubricating oil into the bearing mechanism 1, and the lubricating oil flows into the outer groove area of ​​the connecting channel through the oil inlet pipe 7. At this time, the inner ring 12 rotates slowly and causes the lubricating oil to flow to the rolling element 14, and under the action of the through hole of the rolling element 14, the lubricating oil flows to the inner groove of the inner ring 12, effectively enhancing the effect of smearing the lubricating oil on the inner groove wall of the inner ring 12, and improving the lubrication adequacy between the rolling elements 14 close to the inner ring 12. At the same time, the air pump connected to the fixing mechanism 2 is started. When the fixing mechanism 2 located at the top of a group of fixing mechanisms 2 is stretched by the inflation action of the air pump, the fixing mechanism 2 located at the bottom is contracted by the suction action of the air pump. At this time, the movable plate 3 moves down along the movable groove, thereby driving the rotating component 5 to move down along the limiting cavity, so that the rotating component 5 rotates forward under the limiting action of the limiting ring 41 until the movable plate 3 moves downward along the movable groove, thereby driving the rotating component 5 to move downward ... When the plate 3 moves down to the bottom, the working state of the air pump changes, so that the upper fixed mechanism 2 in a group of fixed mechanisms 2 is contracted by the suction action of the air pump, and the lower fixed mechanism 2 is stretched by the inflation action of the air pump. At this time, the movable plate 3 moves up along the movable groove, thereby driving the rotating component 5 to move up along the limit cavity, so that the rotating component 5 rotates in the opposite direction under the limiting action of the limit ring 41, until the movable plate 3 moves to the top and changes the working state of the air pump again. As the reciprocating suction and exhaust operation of the air pump proceeds, the rotating component 5 is pushed to rotate back and forth in the forward and reverse directions. Since the rotating component 5 is meshed with the isolation block 15, the isolation block 15 is pushed to move back and forth along the connecting channel, thereby fully promoting the circumferential movement of the lubricating oil in the connecting channel, effectively improving the uniform distribution of the lubricating oil in the connecting channel, and at the same time utilizing the reciprocating friction between the push block 6 and the connecting channel to further enhance the effect of the lubricating oil being smeared on the inner groove wall of the inner ring 12.
