Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes, and more specifically, the utility model relates to a sealed bearing bush. Background Art

[0002] A bearing bush is a common mechanical component and is widely used in various mechanical equipment, such as automobile engines, industrial equipment, etc. Its main function is to ensure unobstructed relative movement between the shaft and the bearing housing, and reduce wear and heat generated due to friction. For the existing bearing bushes that are convenient for splicing and installation, the splicing method is relatively complex, which is not convenient for the installation and use of the device.

[0003] After retrieval, a Chinese patent with the publication number CN215487217U discloses a bearing bush that is convenient for splicing and installation. In this utility model, a fixing bolt passes through a reserved hole on the mounting plate and is screwed clockwise into the mounting hole on the bottom plate to complete the connection between the upper bearing bush body and the lower bearing bush body. At this time, the sealing gasket will be subjected to the extrusion force between the bottom plate and the mounting plate, causing structural deformation, so as to fill the gap between the mounting plate and the bottom plate, which is beneficial to increasing the sealing performance between the two. Finally, the limiting ring is placed on both sides of the upper bearing bush body and the lower bearing bush body and fixed on the upper bearing bush body and the lower bearing bush body by screws to complete the splicing of the bearing bush. Since the inner diameter size of the limiting ring is smaller than the inner diameter size of the splicing structure of the upper bearing bush body and the lower bearing bush body, it is beneficial to reduce the probability of the bearing falling out of the inside of the bearing bush. The structure of this bearing bush is simple, which is beneficial to improving the quickness of the splicing method of this bearing bush.

[0004] When the above-mentioned bearing bush is in use, the upper bearing bush body and the lower bearing bush body are connected and fixed by a plurality of fixing bolts. When it is necessary to disassemble the upper bearing bush body and the lower bearing bush body, it is necessary to sequentially remove a plurality of fixing bolts to release the fixation between the upper bearing bush body and the lower bearing bush body. The operation is cumbersome and it is not convenient to quickly install and disassemble the upper bearing bush body and the lower bearing bush body. Summary of the Utility Model

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to the attached drawings of the specification Figures 1-5 , a sealed bearing bush of this embodiment includes an upper bearing bush body 1 and a lower bearing bush body 2, and one side of the upper bearing bush body 1 is in contact with the lower bearing bush body 2. Two gasket rings 6 are fixedly bonded inside both the upper bearing bush body 1 and the lower bearing bush body 2. An air inlet assembly 3 is arranged on the upper bearing bush body 1. The air inlet assembly 3 includes three first side plates 301, an air pipe 302, two side frames 303 and two insertion rods 304. One side of the three first side plates 301 and the two side frames 303 are fixedly connected to the upper bearing bush body 1, and the three first side plates 301 are all fixedly connected to the air pipe 302. Two ends of the air pipe 302 are fixedly communicated with the two side frames 303 respectively. The two insertion rods 304 are respectively located inside the two side frames 303. A liquid inlet assembly 4 is arranged on the lower bearing bush body 2. The liquid inlet assembly 4 includes three second side plates 401, an oil pipe 402, two side plates 403 and two insertion plates 404.

[0028] Furthermore, one side of the three second side plates 401 and the two side plates 403 are fixedly communicated with the lower bearing bush body 2, and the three second side plates 401 are all fixedly connected to the oil pipe 402. Two ends of the oil pipe 402 are fixedly communicated with the two side plates 403 respectively. One side of the two insertion plates 404 are fixedly connected to the two side plates 403 respectively, and the other sides of the two insertion plates 404 respectively extend into the inside of the two side frames 303. Two gaskets 8 are movably arranged between the upper bearing bush body 1 and the lower bearing bush body 2, and the opposite sides of the two gaskets 8 respectively extend into the inside of the upper bearing bush body 1 and the lower bearing bush body 2.

[0029] Furthermore, a connection assembly 7 is arranged on one of the first side plates 301 and one of the second side plates 401. The connection assembly 7 includes a connection pipe 701 and a valve 702. One ends of the two connection pipes 701 are fixedly communicated with one of the first side plates 301 and one of the second side plates 401 respectively. The two valves 702 are respectively fixedly installed on the two connection pipes 701. Outer threaded sleeves 703 are movably arranged on the outer sides of the two connection pipes 701, and one ends of the two outer threaded sleeves 703 are respectively fixedly connected to one of the first side plates 301 and one of the second side plates 401. Protective sleeves 5 are threadedly connected to the two outer threaded sleeves 703.

[0030] Among them, the external pipeline is communicated with the connecting pipe 701 on the lower tile body 2, and the external lubricating oil enters the second side plate 401 through the connecting pipe 701, and finally lubricates the upper tile body 1 and the lower tile body 2. Similarly, closing the valve 702 prevents the lubricating oil from being discharged through the connecting pipe 701 on the second side plate 401. Rotate the protective sleeve 5 and sleeved it on the external thread sleeve 703 to protect the connecting pipe 701 and the valve 702 through the protective sleeve 5. The structure is simple and convenient to use.

[0031] Furthermore, through holes are provided inside both the upper tile body 1 and the lower tile body 2.

[0032] The usage method of this embodiment is as follows:

[0033] During use, contact the lower tile body 2 with the upper tile body 1, and insert the two insertion plates 404 into the two side frames 303 respectively. Then, connect the output end of the air pump to the connecting pipe 701 on the upper tile body 1, and inflate the connecting pipe 701 through the air pump. The gas enters the two side frames 303 through the air pipe 302. Since the pressure inside the two side frames 303 gradually increases, the two insertion rods 304 start to move towards each other, and the two insertion rods 304 move into the two insertion plates 404 respectively, so that the two insertion plates 404 and the two side frames 303 are fixed, and further the upper tile body 1 and the lower tile body 2 are fixed. Moreover, the two gaskets 8 can improve the stability between the upper tile body 1 and the lower tile body 2. Similarly, the fixation between the upper tile body 1 and the lower tile body 2 is released. At the same time, the four cushion rings 6 can improve the sealing performance between the upper tile body 1 and the lower tile body 2. It is a sealed structure, and at the same time, the operation is simple, which is convenient and fast to install and disassemble the upper tile body 1 and the lower tile body 2;

[0034] It should be noted that the insertion rod 304 and the side frame 303 are connected by a spring. When the valve 702 is opened and the air in the air pipe 302 is discharged, the spring rebound can drive the insertion rod 304 away from the insertion plate 404. At the same time, a sealing ring is sleeved on the outside of the insertion rod 304 to prevent air from leaking through the gap between the side frame 303 and the insertion rod 304.

Conventional equipment can be used. In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the prior art and will not be described here either.

[0036] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
