[0002] Bearings play a vital role in the mechanical world. They are a delicate and critical mechanical component, like the joints of a mechanical system, connecting different parts to enable them to run smoothly. Bearings are usually composed of an inner ring, an outer ring, rolling elements and a cage. The inner ring fits tightly with the shaft, the outer ring is connected to the bearing seat, and the rolling elements roll in between, greatly reducing friction resistance. They can withstand loads from different directions, whether radial or axial loads, and can stably support the operation of the machinery. In various mechanical equipment, from automobile engines to large equipment on industrial production lines, bearings play a role silently. Without bearings, the movement of the machinery will become stuck and unstable, and may even cause damage to the equipment. Its precision and reliability are directly It directly affects the performance and life of the entire mechanical system. High-quality bearings can operate stably for a long time in harsh working environments, reduce maintenance costs, and improve production efficiency. Bearings with sealing mechanisms can effectively prevent dust, impurities and moisture from entering the bearings, greatly reducing bearing wear and corrosion and extending the service life of the bearings. At the same time, it can keep the grease or lubricating oil inside the bearings from leaking, ensuring that the bearings always work in a good lubrication state, reducing friction and heat. In addition, the sealed bearings run more stably and reliably, reducing the risk of failures caused by external interference, improving the overall performance and work efficiency of mechanical equipment, and providing more reliable protection for various industrial applications. Therefore, a bearing sealing structure is particularly needed.

[0003] However, the existing bearing sealing structure only provides single-layer sealing protection when in use, and it is not very convenient to add lubricating oil inside when sealing, and the long-term stability of the sealing is not very good. Utility Model Content

A fixed block is installed on the outer side of the inner steel ring, a placement groove is provided on one side surface of the fixed block, a clamping block is provided on the inner side surface of the placement groove, a first sealing ring is fixedly connected to one side surface of the clamping block, a connecting groove is provided on one side surface of the fixed block, and a limit block is provided on the inner side surface of the connecting groove.

[0007] Preferably, a second sealing ring is fixedly connected to the outer surface of the limiting block.

[0008] Preferably, the outer steel ring and the inner steel ring are fixedly connected on both sides of the isolation block.

[0009] Preferably, the inner sides of the two groups of isolation blocks are connected by steel balls to form a rotating structure.

[0010] Preferably, a connection groove is formed through one side surface of the block.

[0011] Preferably, the connecting mechanism includes a feed trough, a feed pipe, a filter screen and a sealing cover. The two side surfaces of the isolation block are penetrated with a feed trough, one side surface of the isolation block is connected to the feed pipe, the inner surface of the feed pipe is installed with a filter screen, and the outer surface of the feed pipe is threadedly connected with a sealing cover.

[0012] Preferably, the material delivery pipe passes through the connection sealing mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the bearing sealing structure installs the fixing block between the outer steel ring and the inner steel ring, then places the clamping block and the first sealing ring into the outer steel ring and rotates them so that the clamping block is clamped into the placement groove, and then the limit block is inserted into the connecting groove to fix the block and the clamping block, and finally the second sealing ring is installed on the outermost side to maintain the seal. This installation method is relatively simple to operate and can quickly realize the sealing installation of the bearing. Moreover, through the cooperation of multiple sealing structures, the sealing performance is greatly improved, effectively preventing external dust, impurities, moisture, etc. from entering the bearing, avoiding these harmful substances from causing damage to the steel balls and other components inside the bearing. It prevents erosion and damage, thereby extending the service life of the bearing. After opening the sealing cover, the lubricating fluid is filtered through the filter and enters the feed pipe, and then enters the feed trough through the feed pipe, and finally flows into the steel balls for lubrication. The setting of the filter ensures the cleanliness of the lubricating fluid and prevents impurities from entering the lubrication system and affecting the lubrication effect. Continuous lubrication can reduce the friction between the steel balls and other components, reduce the degree of wear, make the bearings smoother during operation, reduce energy loss, and improve the working efficiency of the bearings. At the same time, good lubrication also helps to reduce the heat generated by the bearings during operation, avoid bearing performance degradation or damage due to high temperature, and further ensure the stable operation of the bearings.
