Description

Technical Field

[0001] This utility model relates to the field of bearing structure technology, specifically to a high-strength engine bearing. Background Technology

[0002] The bearing shell is the part of a sliding bearing that contacts the journal. It is a semi-cylindrical surface shaped like a tile, and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloys. In special cases, it can be made of wood, engineering plastics, or rubber. There are two types of bearing shells: integral and split. Integral bearing shells are usually called bushings. Integral bearing shells are available with or without oil grooves. The bearing shell and the journal are clearance-fitted. Generally, it does not rotate with the shaft. However, the bearing shell needs to withstand huge loads during operation. These loads come from friction, impact, and other forces generated during the operation of the engine. This makes bearing shells with insufficient strength prone to deformation and breakage, which can lead to equipment failure. Furthermore, if the bearing shell itself is not strong enough under long-term loads, fatigue cracks may appear, especially in areas of stress concentration, thus increasing the probability of bearing shell failure. Utility Model Content

A smooth layer is fixedly connected inside both the lower and upper bearing shells, and reinforcing strips and reinforcing layers are fixedly connected to the outer side of the smooth layer, while reinforcing rings and reinforcing plates are fixedly connected to the outer side of the reinforcing layer.

[0007] Preferably, the reinforcing layer fixedly connected to the outer arc surface of the smooth layer has a semi-cylindrical structure, and the inner arc surface of the reinforcing layer has a corresponding fitting groove at the position of the reinforcing strip, and the axial length of the reinforcing layer is equal to the axial length of the smooth layer.

[0008] Preferably, two sets of reinforcing rings are fixedly connected to both sides of the outer arc surface of the reinforcing layer. Both sets of reinforcing rings are semi-circular ring structures, and the axial cross section formed by the combination of the reinforcing rings and the reinforcing layer is U-shaped.

[0009] Preferably, multiple sets of reinforcing plates are fixedly connected around the outer arc surface of the reinforcing layer at equal intervals in the circumferential direction, and the reinforcing plates have a cuboid structure and an isosceles trapezoidal structure at the end face of the reinforcing plates. At the same time, the end faces of the two ends of the reinforcing plates are fixedly connected to the reinforcing rings on both sides of the reinforcing layer.

The positioning rods are all cylindrical, and positioning holes are opened on the surface of the secondary horizontal plate corresponding to the positions of the positioning rods.

A reinforcing strip 3 and a reinforcing layer 4 are fixedly connected to the outer side of the smooth layer 2, and a reinforcing ring 6 and a reinforcing plate 5 are fixedly connected to the outer side of the reinforcing layer 4.

[0018] In this embodiment, the smooth layer 2 is made of wear-resistant materials such as bronze and anti-friction alloy commonly used in engine bearings, which gives the smooth layer 2 itself the corresponding structural strength. The reinforcing layer 4 and reinforcing strip 3 fixedly connected to the outer side of the smooth layer 2 are both made of high-strength alloy, which can help enhance the strength of the smooth layer 2. At the same time, the reinforcing ring 6 and reinforcing plate 5 fixedly connected to the outer side of the reinforcing layer 4 are also made of high-strength alloy, which can help enhance the strength of the reinforcing layer 4. The positions of the reinforcing ring 6, reinforcing plate 5 and reinforcing strip 3 are combined to form a grid pattern, which can further enhance the overall structural strength of the engine bearing. Furthermore, the main horizontal plate 7, positioning rod 8 and secondary horizontal plate 9 facilitate the quick installation and removal of the upper bearing 10 and the lower bearing 1.

[0020] In this embodiment, as Figure 1 and Figure 3 The lower bearing 1 and the upper bearing 10 have similar overall structures, and the smooth layer 2 inside the lower bearing 1 and the upper bearing 10 are both made of wear-resistant materials such as bronze and anti-friction alloy to ensure that the smooth layer 2 has normal strength.

[0021] As a preferred embodiment, the reinforcing strip 3 has a semi-circular ring structure as a whole, and the end faces at both ends of the reinforcing strip 3 are semi-circular structures, and the length of the reinforcing strip 3 is equal to the arc length of the outer arc surface of the smooth layer 2.

[0022] In this embodiment, as Figure 1 and Figure 3 The reinforcing strip 3 is made of high-strength alloy, which helps to enhance the overall structural strength of the smooth layer 2 and reduces the probability of deformation and breakage of the smooth layer 2.

[0023] In a preferred embodiment, the reinforcing layer 4, which is fixedly connected to the outer arc surface of the smooth layer 2, has a semi-cylindrical structure. The inner arc surface of the reinforcing layer 4 is provided with a fitting groove corresponding to the position of the reinforcing strip 3, and the axial length of the reinforcing layer 4 is equal to the axial length of the smooth layer 2.

[0024] In this embodiment, as Figure 1 and Figure 3 The reinforcing layer 4 is made of high-strength alloy, which can effectively enhance the structural strength of the smooth layer 2. Moreover, the reinforcing strip 3 on the outer side of the smooth layer 2 can help enhance the stability of the connection between the reinforcing layer 4 and the smooth layer 2.

[0025] As a preferred embodiment, two sets of reinforcing rings 6 are fixedly connected to both sides of the outer arc surface of the reinforcing layer 4. Both sets of reinforcing rings 6 are semi-circular ring structures, and the axial cross section formed by the reinforcing rings 6 and the reinforcing layer 4 is U-shaped.

[0026] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The reinforcing ring 6 is made of high-strength alloy, which helps to strengthen the structure of the reinforcing layer 4, thereby helping to reduce the probability of failure of the engine bearing during use.

[0027] In a preferred embodiment, multiple sets of reinforcing plates 5 are fixedly connected around the outer arc surface of the reinforcing layer 4 at equal intervals in the circumferential direction. The reinforcing plates 5 have a cuboid structure and the end faces of the reinforcing plates 5 have an isosceles trapezoidal structure. At the same time, the end faces of the two ends of the reinforcing plates 5 are fixedly connected to the reinforcing rings 6 on both sides of the reinforcing layer 4.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The addition of reinforcing plate 5 can further enhance the structural strength of reinforcing layer 4, thereby effectively enhancing the overall structural strength of the engine bearing and thus helping to increase the upper limit of the load that the engine bearing can withstand.

[0029] In a preferred embodiment, both the main horizontal plate 7 and the secondary horizontal plate 9 are elongated structures. Multiple sets of positioning rods 8 are fixedly connected at equal intervals along the length direction on the upper surface of the main horizontal plate 7, and the positioning rods 8 are all cylindrical.
