Description

Technical Field

[0001] This utility model relates to the field of automotive transmission technology, and in particular to a leak-proof, high-sealing crankshaft. Background Technology

[0002] The crankshaft is one of the core components of a car engine, converting the linear motion of the piston into rotational motion, thereby driving the vehicle.

[0003] The crankshaft is equipped with an oil chamber, oil passage, and oil outlet. Engine oil is delivered to the connection between the crankshaft and the connecting rod through these channels to lubricate the connection. To prevent oil leakage, a plug is inserted into the open end of the oil chamber for sealing. The plug is confined within the open end of the oil chamber by a deformable retaining ring. After long-term use, the plug will wear due to friction and vibration, resulting in a decrease in sealing performance, requiring replacement. During replacement, the retaining ring must first be squeezed and deformed before being removed from the open end of the oil chamber. Due to the narrow space at the open end of the oil chamber, squeezing and moving the retaining ring within the open end of the oil chamber will increase the difficulty of operation. Therefore, this solution proposes a leak-proof, high-sealing crankshaft to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof, high-sealing crankshaft to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof, high-sealing crankshaft, comprising:

[0006] Crankshaft body;

[0007] A lubrication assembly includes an oil chamber located on one side of the crankshaft body, and an oil outlet is provided on the inner wall of one side of the oil chamber. The lubrication assembly is used to deliver engine oil.

[0008] A connecting hole is provided on the inner wall of one side of the oil cavity;

[0009] A sealing ring is inserted into the inside of a connecting hole, and a limiting member is provided on one side of the sealing ring to restrict its movement.

[0010] A threaded post is threadedly inserted into the interior of a connecting hole, and a pushing assembly for pushing the threaded post is provided on one side of the threaded post.

[0011] Preferably, the limiting member includes a fixing post that is inserted into one side of the connection hole, and the fixing post is fixedly connected to one side of the sealing ring.

[0012] Preferably, a fixing ring is fixedly connected to one side of the fixing column, and the fixing ring is inserted into the middle of the sealing ring.

[0013] Preferably, an oil inlet hole is provided on the inner wall at the bottom of the oil chamber, and the oil inlet hole is used to input engine oil into the oil chamber.

[0014] Preferably, the actuating component includes:

[0015] A rotating column, wherein a mounting groove is provided on one side of the fixed column, and the rotating column is inserted into the interior of the rotating column;

[0016] An elastic block is fixedly connected to one side of the rotating column.

[0017] Preferably, a connecting block is fixedly connected to one side of the threaded post, and the connecting block is inserted into the interior of the mounting groove.

[0018] Preferably, a limiting ring is fitted on one side of the rotating column, and a limiting groove is formed on the inner wall of one side of the mounting groove, with the limiting ring inserted into the inside of the limiting groove.

[0019] Preferably, a screwing groove is provided on the other side of the threaded column, and the horizontal longitudinal section of the screwing groove is set to hexagon.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] This invention, through the design of a sealing ring, a limiting component, a threaded post, and a pushing component, allows for the direct insertion of the sealing ring into the connecting hole when fixing its position. The threaded post is then rotated to press and fix the sealing ring inside the connecting hole. Once the threaded post reaches the desired position, the pushing component pushes it, increasing friction between the threaded post and the threaded connection of the connecting hole and reducing the occurrence of the threaded post rotating on its own. Therefore, when the sealing ring needs to be replaced, simply rotating the threaded post suffices, reducing the difficulty of the work. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-4 The high-sealing, leak-proof crankshaft shown includes:

[0029] Crankshaft body 1;

[0030] Lubrication assembly 2 includes an oil chamber 202 opened on one side of crankshaft body 1, and an oil outlet 203 is opened on the inner wall of one side of the oil chamber 202. The lubrication assembly 2 is used to deliver engine oil.

[0031] Connection hole 3 is located on the inner wall of one side of oil cavity 202;

[0032] The sealing ring 4 is inserted into the inside of the connecting hole 3, and a limiting member is provided on one side of the sealing ring 4 to restrict its movement.

[0033] The threaded post 6 is threadedly inserted into the interior of the connecting hole 3, and a pushing component 8 for pushing the threaded post 6 is provided on one side of the threaded post 6.

[0034] Specifically, the limiting component includes a fixing post 5 that is inserted into one side of the connecting hole 3, the fixing post 5 being fixedly connected to one side of the sealing ring 4, and a fixing ring 7 being fixedly connected to one side of the fixing post 5, the fixing ring 7 being inserted into the middle of the sealing ring 4.

[0035] It should be noted that the sealing ring 4 is made of rubber. During use, the sealing ring 4 deforms inside the connecting hole 3 due to the compression of the fixing post 5. This deformation seals the connection between the fixing post 5 and the connecting hole 3, thus preventing oil leakage. The fixing ring 7 is fixedly inserted into the middle of the sealing ring 4. The fixing ring 7 supports the sealing ring 4 and prevents it from deforming randomly.

[0036] Specifically, an oil inlet hole 201 is provided on the inner wall at the bottom of the oil chamber 202, which is used to input engine oil into the oil chamber 202.

[0037] It should be noted that one end of the oil inlet 201 is connected to the oil input mechanism. During use, the oil is input into the oil inlet 201 through the oil input mechanism, and the oil is input into the oil chamber 202 through the oil inlet 201.

[0038] Specifically, the driving component 8 includes:

[0039] The rotating column 804 and the fixed column 5 have an installation groove 803 on one side, and the rotating column 804 is inserted into the interior of the rotating column 804.

[0040] Elastic block 802 is fixedly connected to one side of rotating column 804.

[0041] Specifically, a connecting block 801 is fixedly connected to one side of the threaded post 6, and the connecting block 801 is inserted into the interior of the mounting groove 803.

[0042] It should be noted that the rotating column 804 and the connecting block 801 are both adapted to the mounting groove 803, allowing the rotating column 804 and the connecting block 801 to be inserted into the mounting groove 803. When the threaded column 6 is threadedly inserted into the connecting hole 3, the threaded column 6 drives the connecting block 801 to press against the side of the elastic block 802, causing the elastic block 802 to deform under pressure. Thus, during use, the force of the elastic block 802 restoring its deformation pushes the threaded column 6 away from the fixed column 5. This pushing strengthens the friction between the threaded column 6 and the connecting hole 3, thereby reducing the occurrence of the threaded column 6 rotating on its own.

[0043] Specifically, a limiting ring 805 is fitted on one side of the rotating column 804, and a limiting groove 806 is opened on the inner wall of one side of the mounting groove 803, with the limiting ring 805 inserted into the inside of the limiting groove 806.

[0044] It should be noted that the limiting groove 806 is adapted to the limiting ring 805, so that the limiting ring 805 can be inserted and connected inside the limiting groove 806. The horizontal and longitudinal sections of both the limiting groove 806 and the limiting ring 805 are set as annular, so that the limiting ring 805 can rotate inside the limiting groove 806. The limiting groove 806 blocks the limiting ring 805 from moving out of the limiting groove 806, thereby limiting the movement of the rotating column 804 by limiting the movement of the limiting ring 805.

[0045] Specifically, a screwing groove 601 is provided on the other side of the threaded column 6, and the horizontal longitudinal section of the screwing groove 601 is set as hexagonal.

[0046] It should be noted that the hexagonal turning groove 601 is compatible with a hex wrench, allowing the hex wrench to be inserted into the turning groove 601 and to drive the threaded post 6 to rotate.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
