Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an oil seal structure for an agricultural machinery end cap. Background Technology

[0002] Oil seal is a common term for general sealing components, simply put, it's a seal for lubricating oil. It's a mechanical component used to seal grease. In agricultural machinery, oil seals are generally installed inside end caps, with the inner ring wall abutting against the shaft to achieve a sealing function. However, oil seals can become damaged after long-term use and need to be replaced. Because oil seals are fixedly installed, replacement is inconvenient. To solve this problem, we propose a new oil seal structure for agricultural machinery end caps. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the oil seal in the prior art is fixedly installed, which makes it inconvenient to replace the oil seal, and to propose an oil seal structure for agricultural machinery end caps.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an oil seal structure for an agricultural machinery end cap, including a first end cap, a second end cap fixedly connected to the first end cap, a support ring fixedly connected to the second end cap, an oil seal abutting the support ring, an abutting ring abutting the oil seal, a plurality of abutting parts fixedly connected to the abutting ring, and a rotating part abutting each of the plurality of abutting parts, the rotating part being connected to the second end cap through a connecting mechanism.

[0006] Preferably, the first end cap is provided with a threaded hole.

[0007] Preferably, the connecting mechanism includes a rotating shaft, which is fixedly connected to the rotating part, and the rotating shaft is rotatably connected to the second end cover via a bearing.

[0008] Preferably, the abutting portion has a right-angled trapezoidal structure.

[0009] Preferably, a limiting groove is formed on the abutment ring, a limiting block is provided in the limiting groove, and the second end cap is fixedly connected to the limiting block.

[0010] Preferably, the fixing ear is fixedly connected to the second end cover, a limiting rod is fixedly connected to the fixing ear, a limiting sleeve is sleeved on the limiting rod, a movable sleeve is fixedly connected to the limiting sleeve, the movable sleeve is sleeved on the rotating part, and an elastic element is connected between the fixing ear and the limiting sleeve.

[0011] Preferably, the elastic element is a spring.

[0012] The beneficial effects of the agricultural machinery end cover oil seal structure proposed in this utility model are as follows: by using a rotating part to abut against a contact part, a force is applied to the contact part to abut against the oil seal, thereby fixing the oil seal. When disassembly is required, the rotating part is tapped to rotate, disengaging from the contact part, and the contact ring can be removed, thus removing the oil seal and facilitating its replacement.

[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] Example 3: Reference Figure 1-3 An oil seal structure for an agricultural machinery end cap includes a first end cap 1, a second end cap 2 fixedly connected to the first end cap 1, a support ring 6 fixedly connected to the second end cap 2, an oil seal 4 abutting against the support ring 6, an abutting ring 3 abutting against the oil seal 4, and multiple abutting parts 7 fixedly connected to the abutting ring 3. Each of the multiple abutting parts 7 abuts against a rotating part 13, and the rotating part 13 is connected to the second end cap 2 through a connecting mechanism. By abutting against the abutting parts 7 with the rotating part 13, a force is applied to the abutting parts 7, which abuts the abutting ring 3 against the oil seal 4, thus fixing the oil seal 4. When disassembly is required, the rotating part 13 is tapped to rotate, disengaging from the abutting parts 7, thereby removing the abutting ring 3 and the oil seal 4, facilitating the replacement of the oil seal 4.

[0019] The first end cap 1 has a threaded hole 5, which facilitates the installation of the oil nozzle.

[0020] The connecting mechanism includes a rotating shaft, which is fixedly connected to the rotating part 13. The bearing is a thrust bearing. The rotating shaft is rotatably connected to the second end cover 2 through the bearing. The abutting part 7 has a right-angled trapezoidal structure. The rotating part 13 abuts against the inclined side of the abutting part 7. As the rotation continues, the distance between the rotating part 13 and the abutting part 7 gradually decreases, which will exert an effect on the abutting part 7 and apply pressure to the abutting part 7.

[0021] Example 2: Refer to Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, a limiting groove is provided on the abutting ring 3, and a limiting block 14 is provided in the limiting groove. The second end cover 2 is fixedly connected to the limiting block 14. By using the limiting block 14 and the limiting groove, the abutting ring 3 is positioned, preventing the abutting ring 13 from rotating.

[0022] Example 3: Reference Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 2, the fixing ear 8 is fixedly connected to the second end cover 2, the fixing ear 8 is fixedly connected to the limiting rod 9, the limiting rod 9 is fitted with a limiting sleeve 10, the limiting sleeve 10 is fixedly connected to the moving sleeve 11, the moving sleeve 11 is fitted on the rotating part 13, and an elastic element, which is a spring 12, is connected between the fixing ear 8 and the limiting sleeve 10. By fitting the moving sleeve 11 on the rotating part 13, the rotating part 13 is prevented from rotating, so as to ensure the contact between the rotating part 13 and the abutting part 7.

[0023] When disassembling the oil seal, the moving sleeve 11 is moved, the spring 12 is compressed, causing the moving sleeve 11 to disengage from the rotating part 13. The rotating part 13 is then struck, causing it to rotate and disengage from the abutment part 7, thus allowing the abutment ring 3 to be removed and the oil seal 4 to be disassembled for easy replacement.

[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.
