Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to fatigue-resistant and thermal shock-resistant automotive engine bearings. Background Technology

[0002] Fatigue-resistant and thermal shock-resistant automotive engine bearings are widely used in heavy-duty vehicle and marine engines. They are a high-performance sliding bearing material used in heavy-duty (high-power, high-torque) engines to withstand harsh service conditions and high-frequency impact forces. These bearings are made with special materials and processes, and have high load-bearing capacity, fatigue strength and wear resistance.

[0003] In existing technologies, some fatigue-resistant and thermal shock-resistant automotive engine bearings, without proper oil film lubrication, can lead to a series of problems such as abnormal wear, increased temperature, abnormal engine noise, and decreased oil pressure. In severe cases, this can even cause engine failure and safety hazards. Therefore, maintaining good lubrication of the engine is crucial for protecting the bearings and extending engine life. This paper proposes fatigue-resistant and thermal shock-resistant automotive engine bearings to address these issues. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fatigue-resistant and thermal shock-resistant automotive engine bearing, which aims to improve the problem that some existing devices cannot achieve high lubrication effects on engine bearings.

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

An oil reservoir is fixedly connected inside the bearing sheet. An oil outlet is fixedly connected inside the bearing sheet. The bearing sheet is fixedly connected to the inside of the bearing body. The rubber plug oil inlet is externally connected to the inside of the bearing body. The oil reservoir is externally connected to the inside of the bearing body. The oil outlet is externally connected to the inside of the oil reservoir.

[0007] As a further description of the above technical solution:

[0008] The bearing body has a heat dissipation hole fixedly connected inside, and a long groove fixedly connected inside the bearing body. The heat dissipation hole is opened on the outside and connected to the inside of the long groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the bearing body drives the heat sink plate to move.

[0029] 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.

[0030] Reference Figures 1 to 2 This utility model provides an embodiment of a fatigue-resistant and thermal shock-resistant automotive engine bearing, comprising a bearing body 1 and bearing plates 11, which are in direct contact with the engine shaft. The bearing material needs to possess extremely high wear resistance, fatigue resistance, and good friction-reducing properties. A rubber plug oil inlet hole 12 is fixedly connected inside the bearing plate 11, located within the bearing plate 11. This serves as one of the channels for lubricating oil to enter the bearing. The rubber plug is typically made of oil-resistant, high-temperature-resistant, and elastic rubber material. This rubber plug not only effectively seals the oil inlet hole to prevent lubricating oil leakage but also provides a certain degree of buffering and shock absorption, reducing the impact on the oil inlet structure during engine operation. An oil reservoir 13 is fixedly connected inside the bearing plate 11, also located within the bearing plate 11. This is a spatial structure for storing a certain amount of lubricating oil.

[0031] An oil outlet 14 is fixedly connected inside the bearing shell 11 and communicates with the oil reservoir 13. The bearing shell 11 is fixedly connected to the inside of the bearing body 1. As an important load-bearing structure of the entire automobile engine bearing, it plays a key role. The rubber plug oil inlet 12 is externally connected to the inside of the bearing body 1, and the oil reservoir 13 is externally connected to the inside of the bearing body 1.

[0032] The oil outlet 14 is externally connected to the inside of the oil storage cavity 13. The bearing body 1 is fixedly connected to the inside of the heat dissipation hole 2, which is an important part of the bearing heat dissipation. The bearing body 1 is fixedly connected to the inside of the long groove 3, which is located inside the bearing body 1. It cooperates with the heat dissipation hole 2 to further enhance the heat dissipation performance and structural stability of the bearing. The heat dissipation hole 2 is externally connected to the inside of the long groove 3.

[0033] Reference Figures 2 to 3 An oil groove 4 is fixedly connected inside the bearing shell 1. Located inside the bearing shell 1, it is an important structure for storing and guiding lubricating oil. A guide groove 5 is also fixedly connected inside the bearing shell 1. Its main function is to provide guidance for the bearing shell during installation or operation. A guide rod 6 is fixedly connected inside the bearing shell 1. It is a component that works in conjunction with the guide groove 5.

[0034] The bearing body 1 has a fixed internal connection with a slot 7, which is a structure for installing and fixing a locking block 8. The slot 7 has a fixed internal connection with a locking block 8, which is a component used to cooperate with the slot 7. It usually has a specific shape and size to match the slot 7. The locking block 8 has a fixed external connection with a heat dissipation plate 9, which is an important component of the bearing heat dissipation. It is mainly used to dissipate the heat generated by the bearing during operation.

[0035] Reference Figures 3 to 4 A connecting plate 10 is fixedly connected to the outside of the heat sink 9. It is used to connect the heat sink 9 and enhance the structural stability and connection reliability of the heat sink 9. The connecting plate 10 is fixedly connected to the outside of the heat sink 9. A long groove 3 is opened inside the bearing body 1. The heat sink 9 is fixedly connected inside the long groove 3. A slot 7 is opened inside the bearing body 1. A locking block 8 is fixedly connected inside the slot 7.

[0036] Working principle: When the car engine is running, lubricating oil first enters the bearing shell 11 through the rubber plug oil inlet hole 12 inside the bearing shell 11. The rubber plug seals the oil inlet hole to prevent lubricating oil leakage and also acts as a buffer and damper. The lubricating oil entering the bearing shell flows into the oil reservoir 13 inside the bearing shell 11 for storage, and then flows out from the oil outlet hole 14 connected to the oil reservoir 13, providing lubrication to the friction surface between the shaft and the bearing shell 11. The oil groove 4 inside the bearing shell body 1 collects and guides the lubricating oil.

[0037] Ensure proper distribution of heat within the bearing bush. Heat is generated by friction between the shaft and the bearing bush. The heat dissipation holes 2 inside the bearing bush body 1 cooperate with the elongated groove 3 to form a heat dissipation channel. The heat dissipation plate 9 is fixed in the slot 7 of the bearing bush body 1 by the locking block 8 and connected to the elongated groove 3. The heat dissipation plate 9 and its connecting plate 10 absorb and dissipate the heat generated by the bearing bush. Cool air enters the bearing bush through the heat dissipation holes 2 and the elongated groove 3 for heat exchange to lower the temperature. Simultaneously, the guide groove 5 and guide rod 6 inside the bearing bush body 1 play a guiding role during bearing bush installation and operation, ensuring accurate installation and normal operation of the bearing bush.

[0038] 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.
