Description

Technical Field

[0001] This utility model relates to the field of diesel engine bearing installation technology, and in particular to a diesel engine bearing limiting installation structure. Background Technology

[0002] Diesel engine bearings are crucial precision components in diesel engines, typically installed between the connecting rod big end and crankshaft pin, or between the engine block main bearing housing and crankshaft main journal. Their core function is to act as sliding bearings, supporting the high-speed rotating crankshaft to achieve efficient and smooth power transmission while significantly reducing wear. To ensure functionality, bearings usually employ a double- or multi-layer metal structure, using low-carbon steel as the backing to provide mechanical strength, and then casting or plating layers of anti-friction materials such as copper-lead alloys, Babbitt metals, or aluminum-tin alloys on top. The reliable operation of bearings depends not only on their material properties but also on their ability to achieve precise and secure installation in the bearing housing, preventing circumferential rotation or axial movement under cyclic alternating loads and oil film pressure.

[0003] Currently, during bearing installation, operators need to align the locating lip of the bearing with the locating groove of the bearing housing, and then apply pressure to insert the bearing into the housing hole. However, due to the small size and poor visibility of the bearing housing itself, the entire installation process is time-consuming and labor-intensive, limiting the assembly efficiency of diesel engines.

Detailed Implementation

[0024] 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.

[0025] Example 1:

[0026] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a diesel engine bearing limiting installation structure, including a base plate 1, a vertical plate 2 fixedly connected to the upper surface of the base plate 1, a rectangular block 3 fixedly connected to the upper surface of the vertical plate 2, an electric push rod 4 fixedly connected to the upper surface of the base plate 1, a rectangular block 5 fixedly connected to the output end of the electric push rod 4, a connecting block 6 slidably connected to the outer wall of the rectangular block 5, the outer wall of the connecting block 6 being rotatably connected to the outer wall of the rectangular block 3, a slider 7 slidably connected to the inner wall of the connecting block 6, a slide rail 8 fixedly connected to the upper surface of the rectangular block 3, the outer wall of the slide rail 8 being slidably connected to the inner wall of the slider 7, and a clamping assembly provided on the outer wall of the slider 7.

[0027] Specifically, the base plate 1 fixes the electric push rod 4, ensuring its stability during operation. Rectangular block 3 provides a connection point for the rotation of connecting block 6, ensuring its stable rotation. Rectangular block 3 provides a base for the installation and sliding of slider 7. The output end of the electric push rod 4 can push the connected rectangular block 5 to move. Connecting block 6 converts the linear motion of rectangular block 5 into the sliding of slider 7. The sliding of slider 7 can drive the clamping assembly to move synchronously, ultimately achieving the installation of the bearing body 11. The slide rail 8 provides a sliding track for slider 7, limiting its direction of movement.

[0028] Reference Figure 2 The clamping assembly includes a clamp 9, the outer wall of which is fixedly connected to the outer wall of the slider 7, and a limit block 10 is fixedly connected to the outer wall of the clamp 9.

[0029] Specifically, the clamp 9 holds the bearing body 11 by its own structure to prevent the bearing body 11 from falling off, and the limiting block 10 is used to limit the installation position of the bearing body 11 on the clamp 9 to prevent the bearing body 11 from sliding or shifting.

[0030] Reference Figure 2 and Figure 3 The outer wall of the clamp 9 is connected to the bearing body 11, and the outer wall of the limiting block 10 is slidably connected to the inner wall of the bearing body 11. The inner wall of the base plate 1 is slidably connected to the slide rod 12, the top end of the slide rod 12 is fixedly connected to the handle 13, the outer wall of the slide rod 12 is fixedly connected to the ring 14, and the outer wall of the slide rod 12 is fixedly connected to the locking block 15. The bottom end of the ring 14 is fixedly connected to one end of the spring 16, and the other end of the spring 16 is fixedly connected to the inner wall of the base plate 1. The lower surface of the base plate 1 is connected to the mounting plate 20, the upper surface of the mounting plate 20 is provided with a through groove 17, the inner wall of the mounting plate 20 is provided with a rotating groove 18, and the inner wall of the mounting plate 20 is provided with a semi-groove 19. The outer wall of the locking block 15 is slidably connected to the inner wall of the through groove 17, the outer wall of the locking block 15 is slidably connected to the inner wall of the rotating groove 18, and the outer wall of the locking block 15 is slidably connected to the inner wall of the semi-groove 19.

[0031] Specifically, the bearing body 11 serves as a lubricant and support, the handle 13 provides a force point for the operator, and the movement and rotation of the slide rod 12 can be controlled by pressing and rotating the handle 13. The ring 14 transmits the elastic force of the spring 16 to the slide rod 12, enabling the slide rod 12 to have the ability to automatically reset, ensuring that the locking block 15 is stably locked in the groove. The locking block 15 achieves the installation of the base plate 1 and the mounting plate 20 by cooperating with different grooves. The through groove 17 is the channel for the locking block 15 to enter the interior of the mounting plate 20. The rotating groove 18 allows the locking block 15 to rotate inside the mounting plate 20, so that the locking block 15 changes from the state of passing through the through groove 17 to the state of aligning with the half groove 19. After the locking block 15 rotates, it can fall into the half groove 19. The locking block 15 is locked by the limiting effect of the half groove 19, thus fixing the base plate 1 and the mounting plate 20.

[0032] Example 2:

[0033] Reference Figure 4 In this embodiment, another structure is provided in the above embodiment: the base plate 1 is internally threaded with a bolt 21, the upper surface of the mounting plate 20 is provided with a threaded groove 22, and the outer wall of the bolt 21 is threadedly connected to the inner wall of the threaded groove 22.

[0034] Specifically, the threaded groove 22 is formed on the upper surface of the mounting plate 20, so that the bolt 21 can fix the base plate 1 to the mounting plate 20 through threaded connection.

[0035] Working principle: The bearing body 11 is placed between the clamps 9 and the slot of the bearing body 11 is aligned with the limiting block 10. The electric push rod 4 is started to drive the rectangular block 5 to move downward. The movement of the rectangular block 5 drives the connecting block 6 to rotate. The rotation of the connecting block 6 drives the slider 7 to slide inward on the outer wall of the slide rail 8. The sliding of the slider 7 drives the clamps 9 and the limiting block 10 to slide inward, which achieves the effect of quick installation and limiting of the bearing, which helps to reduce the difficulty of installation operation and improve assembly efficiency.

[0036] When the fixture 9 needs to be disassembled, press the handle 13 to move the locking block 15 downward and compress the spring 16. The locking block 15 leaves the half-groove 19 and enters the rotating groove 18. Rotate the handle 13 to rotate the locking block 15 until it is parallel to the through groove 17. The locking block 15 leaves the mounting plate 20 through the through groove 17. When the fixture 9 needs to be installed, align the locking block 15 with the through groove 17, press and rotate the handle 13 to align the locking block 15 with the half-groove 19, and release the handle 13. Under the action of the spring 16, the locking block 15 enters the half-groove 19, thus achieving the effect of installing and disassembling the fixture 9. This is beneficial for the fixture 9 to be quickly fixed in a new position, improves the reuse rate of the fixture 9, and reduces the additional cost of equipment modification.

[0037] In actual use, this diesel engine bearing bush limiting installation structure can not only achieve the effect of quick installation and limiting of the bearing bush, but also achieve the effect of installing and removing the clamp 9.

[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.
