High-efficiency heat dissipation type oil retaining ring

Abstract

This utility model discloses a high-efficiency heat-dissipating oil baffle ring, including an oil baffle ring body. An inner ring seat is provided on the inner side of the oil baffle ring body, and a heat dissipation space is formed on the inner ring seat. A heat dissipation mechanism is provided inside the heat dissipation space, and the heat dissipation mechanism includes a heat dissipation component fixed on the inner ring seat. An outer heat dissipation port is provided on the outer ring surface of the oil baffle ring body. In this high-efficiency heat-dissipating oil baffle ring, multiple sets of rectangular outer heat dissipation ports evenly spaced on the outer ring surface of the oil baffle ring body serve as communication channels between the heat dissipation space and the external environment. This allows hot air treated by the heat dissipation fins and the through-channels within the heat dissipation space to be dissipated to the outside through the outer heat dissipation ports. Furthermore, because the inner ring seat and the heat dissipation component are concentric circles, and the oil baffle ring body and its heat dissipation mechanism are integrally formed, the stability of the overall structure and the uniformity of heat dissipation are ensured, thereby effectively realizing the heat dissipation function of the oil baffle ring.

Description

Technical Field

[0001] This utility model relates to the field of mechanical parts, specifically a high-efficiency heat dissipation oil baffle ring. Background Technology

[0002] Thrust bearings generally consist of two or more thrust washers and several rolling elements. Thrust washers are typically divided into shaft plates and seat plates. The most common type of rolling element is a single unit composed of an iron or copper cage. The most common type of this bearing is the steel ball thrust bearing. Thrust bearings are designed and used to withstand axial loads. When thrust bearing shells on the market are damaged during use, users can only replace the entire part, which can cause economic losses over time. Furthermore, thrust bearing shells do not have an independent lubrication system, which can lead to severe wear on the inner wall over extended periods. To solve the above problems, after searching, Chinese patent with publication number CN207935276U was found, which discloses an engine thrust bearing. The paper includes an oil baffle ring, a housing and a mounting hole. A connecting pad is connected to the outer side of the oil baffle ring, and a fixing pad is fixed to the outer side of the connecting pad. An outer sleeve is distributed on the outer side of the fixing pad, and a notch is embedded in the middle of the outer sleeve. The housing is disposed on both sides of the outer sleeve. Although the above-mentioned device can disassemble the internal parts of the thrust bearing by removing the pin, in actual use, the oil retainer ring is prone to high temperature when working and cannot dissipate heat efficiently. High temperature will cause the strength and hardness of the metal material (such as steel and copper alloy) of the oil retainer ring to decrease. Long-term exposure to high temperature environment will easily cause deformation, cracking, or even breakage due to thermal fatigue, directly losing its core function of preventing lubricating oil leakage. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency heat-dissipating oil baffle ring to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a high-efficiency heat-dissipating oil baffle ring is provided, including an oil baffle ring body, an inner ring seat on the inner side of the oil baffle ring body, and a heat dissipation space on the inner ring seat. A heat dissipation mechanism is provided inside the heat dissipation space, and the heat dissipation mechanism includes a heat dissipation component fixed on the inner ring seat. An external heat dissipation port is provided on the outer ring surface of the oil baffle ring body.

[0005] Furthermore, multiple sets of external heat dissipation vents are equidistantly arranged along the outer ring surface of the oil baffle ring body, and the external heat dissipation vents are rectangular.

[0006] Furthermore, the heat dissipation component includes multiple sets of equidistantly distributed heat dissipation fins, and the heat dissipation fins are in the shape of a ring.

[0007] Furthermore, the multiple sets of heat dissipation fins are annular, and multiple sets of through channels are equally spaced on the heat dissipation fins, the through channels being annular.

[0008] Furthermore, the cross-section of the oil baffle ring body is U-shaped, and the cross-section of the inner ring seat at the bottom of the oil baffle ring body is dovetail-shaped.

[0009] Furthermore, the inner ring seat and the heat dissipation assembly are in a concentric circle structure, and the oil baffle ring body and the heat dissipation mechanism on it are integrally formed.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this solution: multiple sets of annular through channels evenly spaced on the heat dissipation fins can promote airflow inside the heat dissipation space, while multiple sets of rectangular external heat dissipation vents evenly spaced on the outer ring surface of the oil baffle ring body serve as communication channels between the heat dissipation space and the external environment. This allows the hot air in the heat dissipation space, after being processed by the heat dissipation fins and through channels, to be dissipated to the outside through the external heat dissipation vents. Furthermore, since the inner ring seat and the heat dissipation component are concentric circle structures, and the oil baffle ring body and the heat dissipation mechanism on it are integrally formed, the stability of the overall structure and the uniformity of heat dissipation are ensured, thereby effectively realizing the heat dissipation function of the oil baffle ring. 2. This solution uses powder metallurgy to integrally form the oil baffle ring body and the heat dissipation mechanism on it, which can ensure the tightness of the connection and the integrity of the structure, reduce gaps and loosening caused by assembly, and improve the overall structural strength and stability. At the same time, the powder metallurgy process can control the material composition and structure, which is conducive to the stable performance of the heat dissipation mechanism. Furthermore, integral forming reduces assembly steps and improves production efficiency. Attached Figure Description

[0013] Please see Figure 1-5This utility model provides a high-efficiency heat-dissipating oil baffle ring, including an oil baffle ring body 1, an inner ring seat 12 on the inner side of the oil baffle ring body 1, and a heat dissipation space 11 on the inner ring seat 12. A heat dissipation mechanism 2 is provided inside the heat dissipation space 11. The heat dissipation mechanism 2 includes a heat dissipation component 21 fixed on the inner ring seat 12. An outer heat dissipation port 20 is provided on the outer ring surface of the oil baffle ring body 1.

[0014] In a preferred embodiment, multiple sets of external heat dissipation vents 20 are equidistantly arranged along the outer ring surface of the oil baffle ring body 1, and the external heat dissipation vents 20 are rectangular.

[0015] The heat dissipation assembly 21 includes multiple sets of equally spaced heat dissipation fins 211, and the heat dissipation fins 211 are in the shape of a ring.

[0016] Multiple sets of heat dissipation fins 211 are arranged in a ring shape, and multiple sets of through channels 212 are equally spaced on the heat dissipation fins 211, with the through channels 212 being ring-shaped.

[0017] The inner ring seat 12 and the heat dissipation component 21 are in a concentric circle structure, and the oil baffle ring body 1 and the heat dissipation mechanism 2 on it are integrally formed.

[0018] Working principle: During the use of the oil baffle ring, the oil baffle ring body 1 plays the role of oil baffle. The heat dissipation space 11 opened on the inner ring seat 12 provides a place for heat dissipation. The heat dissipation component 21 fixed on the inner ring seat 12 inside the heat dissipation space 11 increases the heat dissipation area through multiple sets of equally distributed and annular heat dissipation fins 211. At the same time, multiple sets of annular through channels 212 equally distributed on the heat dissipation fins 211 can promote air flow inside the heat dissipation space 11. The multiple sets of rectangular external heat dissipation ports 20 equally distributed on the outer ring surface of the oil baffle ring body 1 serve as communication channels between the heat dissipation space 11 and the external environment. This allows the hot air in the heat dissipation space 11, after being processed by the heat dissipation fins 211 and through channels 212, to be dissipated to the outside through the external heat dissipation ports 20. Furthermore, since the inner ring seat 12 and the heat dissipation component 21 are concentric circles, and the oil baffle ring body 1 and the heat dissipation mechanism 2 on it are integrally formed, the stability of the overall structure and the uniformity of heat dissipation are ensured, thereby effectively realizing the heat dissipation function of the oil baffle ring. The heat dissipation area is increased by the heat dissipation fins 211, the internal airflow is promoted by the through channel 212, and the internal and external air exchange is realized by the external heat dissipation port 20. The heat dissipation efficiency of the oil baffle ring is significantly improved. At the same time, the one-piece molded structure enhances the overall structural strength and stability and extends the service life of the oil baffle ring.

[0019] In a preferred embodiment, the cross-section of the oil baffle ring body 1 is U-shaped, and the cross-section of the inner ring seat 12 at the bottom of the oil baffle ring body 1 is dovetail-shaped.

[0020] like Figure 1-4As shown: the cross-section of the oil baffle ring body 1 is U-shaped, which can effectively form a surrounding oil baffle structure, enhance the blocking effect on oil, reduce oil leakage, and at the same time, the U-shaped structure can increase the oil baffle area and improve the reliability of oil baffle; while the cross-section of the inner ring seat 12 at the bottom of the oil baffle ring body 1 is dovetail-shaped, which can not only enhance the structural strength of the connection between the inner ring seat 12 and the oil baffle ring body 1 and improve the overall stability, but also better adapt to the installation position, improve the installation firmness, reduce loosening during use, and further ensure the performance of the oil baffle ring.

[0021] like Figure 1 As shown: The oil baffle ring body 1 and the heat dissipation mechanism 2 on it are integrally formed by powder metallurgy, which can ensure the tightness of the connection and the structural integrity of the two, reduce gaps and looseness caused by assembly, and improve the overall structural strength and stability. At the same time, the powder metallurgy process can control the material composition and structure, which is conducive to the stable performance of heat dissipation mechanism 2. Furthermore, the integral forming reduces assembly steps, improves production efficiency, reduces production costs, and also makes the oil baffle ring body 1 and heat dissipation mechanism 2 more evenly stressed during operation, thus extending their service life.
