Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sealing rings, and particularly relates to a hollow serrated sealing ring device for sealing diesel engine parts. Background Technique
[0002] Diesel engines are widely used in various fields due to their good economy, compact structure, light weight for easy movement, wide power range and other factors. At the same time, during the operation of diesel engines, there are also processes such as lubrication, cooling, intake and exhaust, that is, there is a cycle between oil, water and gas. Therefore, there are different sealing methods between each system and parts, and each system and parts also become one of the important factors affecting the operation of diesel engines.
[0003] The sealing between diesel engine parts generally uses a conventional O-ring for sealing. Since the contact surface between this O-ring and parts is less, over time and due to the influence of diesel engine operation vibration, etc., the sealing may not be tight, resulting in oil leakage and water leakage of the diesel engine, etc., thereby affecting the use of the diesel engine. Therefore, improvements are proposed. Content of the Utility Model

The cross-sectional shape of the sealing ring body is composed of an upper arc structure and a lower serrated structure connected. The left and right sides of the upper arc structure and the lower serrated structure are both connected through a smooth transition structure.
[0007] Among them, the smooth transition structure on the left and right sides of the upper arc structure and the lower serrated structure includes a linear transition structure and an arc transition structure. One end of the linear transition structure is connected to the corresponding end of the upper arc structure. The other end of the linear transition structure is connected to one end of the arc transition structure. The other end of the arc transition structure is connected to the corresponding end of the lower serrated structure.
[0008] Further, the linear transition structures connected to both sides of the upper arc structure are in a shape with the lower part expanding outwards.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0018] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0019] Please refer to Figure 1-2 , and detail the embodiments of the present utility model.
[0020] Embodiment: Refer to Figure 1-2As shown in the figure, a hollow serrated sealing ring device for diesel engine parts includes a ring-shaped sealing ring body 1. The cross-sectional shape of the sealing ring body 1 is composed of an upper arc structure 1-1 and a lower serrated structure 1-2 connected. The left and right sides of the upper arc structure 1-1 and the lower serrated structure 1-2 are connected by smooth transition structures. In this embodiment, the arc radius of the upper arc structure 1-1 is R3mm, the serrated angle of the lower serrated structure 1-2 is 60°, and the serrated pitch is 0.9mm.
[0021] With the above structure, the upper part of the sealing ring still adopts a circular structure to ensure correct fitting with the installed parts; the middle part adopts smooth transition to reserve enough space for the design of the lower part; the lower part adopts a serrated structure, which not only ensures sufficient contact between the sealing ring and the parts to form a multi-layer sealing structure, but also ensures that there is enough storage space for the protruding serrations when the sealing ring is squeezed.
[0022] In this embodiment, the smooth transition structures on the left and right sides of the upper arc structure 1-1 and the lower serrated structure 1-2 include a linear transition structure 1-3 and an arc transition structure 1-4. One end of the linear transition structure 1-3 is connected to the corresponding end of the upper arc structure 1-1, the other end of the linear transition structure 1-3 is connected to one end of the arc transition structure 1-4, and the other end of the arc transition structure 1-4 is connected to the corresponding end of the lower serrated structure 1-2. In this embodiment, the two sides of the linear transition structure 1-3 connected to both sides of the upper arc structure 1-1 are symmetric and expand outward at an angle of 30° downward.
[0023] With the above structure, a linear arc transition at a certain angle is adopted on both sides in the middle of the sealing ring, providing a technical guarantee for reserving enough space for the design of the lower part.
[0024] In a specific embodiment: a ring-shaped hollow inner cavity structure 1-5 is provided inside the sealing ring body 1 following the shape of the sealing ring body 1. In this embodiment, the wall thickness formed between the inner surface of the hollow inner cavity structure 1-5 and the outer surface of the sealing ring is 2mm, and the total height of the cross-section of the sealing ring is 11mm.
[0025] Preferably, the cross-section of the hollow inner cavity structure 1-5 is in a triangular structure.
[0026] The three corners of the triangular cross-section of the hollow inner cavity structure 1-5 are in a rounded corner transition.
[0027] With the above structure, a hollow design is adopted in the middle of the sealing ring, so that the sealing ring maintains its existing support. When the sealing ring is squeezed, its hollow design can accommodate the extrusion amount. When the parts vibrate, the hollow design enables the sealing ring to maintain a large resilience, ensuring the seal between the parts and reducing phenomena such as dripping and leakage of the diesel engine.
[0028] Preferably, the sealing ring body 1 is made of rubber material, which is a common material used in the manufacture of existing sealing rings, easy to implement and convenient to manufacture.
[0029] In summary, the present utility model designs a new sealing ring structure for the sealing between various components of a diesel engine, which has a serrated sealing surface and a hollow structure inside. This not only ensures the sealing performance of the components, but also endows the sealing ring with greater resilience and support through its hollow structure, thereby reducing phenomena such as dripping and leakage of the diesel engine, meeting the operating requirements of the diesel engine, and improving the safety and operability of the diesel engine; the structure is simple, the application range is wide, and it can be popularized and used in other models.
