Description

Technical Field

[0001] This utility model relates to the field of bushing technology, and in particular to a bushing. Background Technology

[0002] A bushing is a mechanical component primarily used to support rotating or reciprocating shafts, reducing friction and wear while maintaining the shaft's positional accuracy. It is typically mounted in a bearing housing or bore to secure and guide the shaft or other moving parts.

[0003] In the existing technology, the bushing does not have a dustproof function. Dust and small debris can enter the interior and cause friction with the bushing, which will accelerate the wear of the bushing and reduce its service life. Utility Model Content

[0004] The purpose of this utility model is to provide a bushing to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bushing includes a mounting part, a bushing is provided on one side of the mounting part, a plurality of through holes are opened on the outer periphery of the bushing, and a first mounting groove and a second mounting groove are respectively opened at both ends of the inner cavity of the bushing, and a sealing element is provided in both the first mounting groove and the second mounting groove.

[0007] Preferably, a step is installed at one end of the outer periphery of the mounting part, and the step is in the shape of a ring.

[0008] Preferably, all of the through holes are hexagonal, and the through holes form a honeycomb pattern on the outer periphery of the bushing.

[0009] Preferably, the bushing is cylindrical, the mounting portion is annular, and the inner diameter of the mounting portion is the same as the outer diameter of the bushing.

[0010] Preferably, the seal, the first mounting groove and the second mounting groove are all annular, and the seal is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the design of a bushing, allows the bushing to be installed on the bearing housing. A first and second mounting groove on both sides of the bushing allow for the installation of a seal. This seal prevents dust and fine debris from entering the bushing and contributing to friction between the shaft and bushing, thus accelerating wear. Compared to existing technologies, this device, through its seal, prevents dust from entering the bushing, increasing wear and extending its service life. It solves the problem in existing technologies where dust and fine debris can enter the bushing, accelerating wear and reducing its lifespan. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1 to 3 A bushing includes a mounting part 1, a bushing 2 is provided on one side of the mounting part 1, a plurality of through holes 3 are provided on the outer periphery of the bushing 2, and a first mounting groove 4 and a second mounting groove 5 are respectively provided at both ends of the inner cavity of the bushing 2, and a sealing element 6 is provided in both the first mounting groove 4 and the second mounting groove 5.

[0019] In use, this device allows the bushing 2 to be installed on the bearing housing. A seal 6 can be installed through the first mounting groove 4 and the second mounting groove 5 on both sides of the bushing 2. The seal 6 prevents dust and small debris from entering the interior of the bushing 2 and participating in the friction between the shaft and the bushing 2, thus accelerating the wear of both. Compared with existing technologies, this device, through the seal 6, prevents dust from entering the bushing 2, thus increasing its wear and service life. This solves the problem in existing technologies where dust and small debris can enter the bushing 2, accelerating its wear and reducing its service life.

[0020] Furthermore, a step 7 is installed at one end of the outer periphery of the mounting part 1, and the step 7 is in the shape of a ring. The mounting part 1 can be used to install a flange. When the flange is disassembled, the step 7 provides a stable fixing point for disassembly tools (such as wrenches, adjustable wrenches, socket wrenches, etc.), so that when the flange is disassembled, a greater torque can be applied to loosen the fastened bolts or nuts.

[0021] Furthermore, all of the aforementioned through holes 3 are hexagonal, and the aforementioned through holes 3 form a honeycomb pattern on the outer periphery of the bushing 2. By providing the through holes 3, the material used in the bushing 2 can be reduced without changing the strength and function of the bushing 2, and additional space can be formed inside the bushing 2. This space can be used to store lubricating oil, so that lubrication can be maintained between the bushing 2 and the shaft for a longer period of time, reducing wear and extending service life.

[0022] Furthermore, the bushing 2 is cylindrical, and the mounting part 1 is annular. The inner diameter of the mounting part 1 is the same as the outer diameter of the bushing 2. By ensuring that the inner diameter of the mounting part 1 is the same as the outer diameter of the bushing 2, a precise fit can be achieved between the bushing 2 and the mounting part 1, reducing errors in the assembly process and improving the assembly accuracy of the components.

[0023] Furthermore, the sealing element 6, the first mounting groove 4, and the second mounting groove 5 are all annular, and the sealing element 6 is made of rubber. By setting the sealing element 6 to an annular shape, the sealing element 6 is adapted to the first mounting groove 4 and the second mounting groove 5. By setting the material of the sealing element 6 to rubber, because rubber has good elasticity, it can deform when compressed and return to its original shape after the pressure is released. This characteristic allows the rubber sealing element 6 to effectively fill the tiny gaps at the mating surface with the bushing 2, thereby increasing the sealing effect.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
