Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a novel copper alloy bearing. Background Technology

[0002] In mechanical equipment, copper alloy bearings are required for shaft installation in many low-speed, heavy-load applications.

[0003] When filling the oil groove inside the bearing bush with oil, the oil is injected through the oil inlet. Before installing the bearing bush, it needs to be moved to the required position and aligned with the shaft and bearing housing. Since the bearing bush is made of soft material, its oil inlet structure is fragile. If an accidental collision occurs during handling or alignment, the edge of the oil inlet will be deformed, cracked, or even partially damaged. Once the oil inlet is structurally damaged, it will cause serious lubrication failure: during subsequent forced oil filling, the lubricating oil will overflow from the damaged gap in a spray or seep manner, thus wasting the lubricating oil. Therefore, this solution proposes a new type of copper alloy bearing bush to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a novel copper alloy bearing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel copper alloy bearing, comprising:

[0006] Bearing body;

[0007] Oil groove assembly, wherein the oil groove assembly is disposed inside the bearing body;

[0008] The oil filling hole is located on the outer wall of the bearing body and is used to inject oil into the oil tank assembly.

[0009] A sealing assembly includes a movable plate disposed in the middle of the bearing body, a rubber pad disposed at the bottom of the movable plate to protect the oil filling hole, and a movable component disposed on one side of the movable plate for moving the position of the movable plate.

[0023] 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.

[0024] This utility model provides, for example Figure 1-4 The novel copper alloy bearing shown includes:

[0025] Bearing body 1;

[0026] Oil groove assembly 2 is installed inside the bearing body 1;

[0027] Oil filling hole 3 is located on the outer wall of the bearing body 1 and is used to inject oil into the oil groove assembly 2.

[0028] The sealing assembly 4 includes a movable plate 403 disposed in the middle of the bearing body 1. A rubber pad 402 is disposed at the bottom of the movable plate 403 to protect the oil filling hole 3. A movable component for moving the position of the movable plate 403 is disposed on one side of the movable plate 403.

[0029] It should be noted that the bearing body 1 is made of copper alloy and adopts an integrated structure design, which has a stronger load-bearing capacity. The oil filling holes 3 are axially evenly distributed, with four holes pointing towards the center and being through holes. This design facilitates the flow of lubricating oil into the oil groove assembly 2. During use, the moving plate 403 is moved by the moving component, and the rubber pad 402 is moved to the oil filling hole 3 by the moving plate 403. The moving plate 403 and the rubber pad 402 block the oil filling hole 3, preventing oil leakage caused by bumps during transportation.

[0030] Specifically, the moving component includes a push plate 406 fixedly connected to one side of the moving plate 403, a spring 408 provided on one side of the push plate 406, and a pressing plate 401 fixedly connected to the other side of the moving plate 403. The pressing plate 401 is used to drive the moving plate 403 to move. A fixing ring 405 is sleeved on one side of the bearing body 1. A through groove 404 is opened on one side of the fixing ring 405. The moving plate 403 is inserted into the inside of the through groove 404. A sliding groove 409 is opened on the inner wall of one side of the through groove 404. The push plate 406 and the spring 408 are both inserted into the inside of the sliding groove 409. A limiting rod 407 is fixedly connected between the inner walls on both sides of the sliding groove 409. The limiting rod 407 is inserted into the top of the push plate 406.

[0031] It should be noted that the pressing plate 401 is used to drive the moving plate 403 to move. When it is necessary to remove the moving plate 403 from the oil filling hole 3, it can be moved directly by the pressing plate 401. The spring 408 is set on the side of the push plate 406 away from the moving plate 403. During use, it is used to move the push plate 406 and the moving plate 403 toward the pressing plate 401. The push plate 406 is adapted to the sliding groove 409, so that the push plate 406 can slide inside the cavity 406. There are at least two limiting rods 407, which are inserted and connected to the push plate 406. The limiting rods 407 restrict the movement direction of the push plate 406 to prevent the push plate 406 from shaking randomly during use.

[0032] Specifically, the oil groove assembly 2 includes multiple axial oil grooves 201 formed on the inner wall of the bearing body 1, and multiple annular oil grooves 202 formed on the inner wall of the bearing body 1, with the axial oil grooves 201 and the annular oil grooves 202 communicating with each other.

[0033] It should be noted that the axial oil groove 201 adopts a semi-circular arc design with chamfered edges for a smooth transition, which is beneficial for oil storage and lubrication. The evenly distributed design of the four axial oil grooves 201 further facilitates the uniform distribution of lubricating oil, resulting in more thorough lubrication. Similarly, the annular oil groove 202 also adopts a semi-circular arc design with chamfered edges for a smooth transition, which is beneficial for oil storage and lubrication. The evenly distributed design of the three annular oil grooves 202 connects the axial oil grooves 201 and the annular oil grooves 202, enhancing the flow range of lubricating oil or grease, resulting in a larger lubrication area and better lubrication effect.

[0034] Specifically, the bearing body 1 is symmetrically fitted with positioning shoulders 5 on both sides, and a limit ring 501 is fixedly connected to one side of one of the positioning shoulders 5.

[0035] It should be noted that the design of the positioning shoulders 5, the fixing ring 405 and the limiting ring 501 at both ends of the outer side of the bearing body 1 plays a role in axial positioning of the bearing, preventing axial movement between the bearing body 1 and the shaft, and making installation more convenient.

[0036] Furthermore: When using:

[0037] The second step is to design and manufacture suitable copper alloy bearings based on the diameter of the shaft.

[0038] The third step is to clean the bearing shell thoroughly and apply an appropriate amount of lubricating oil or grease to the inside.

[0039] Fourth step: First, move the moving plate 403 to one side of the push plate by pressing the plate 401 to expose the oil filling hole 3. Then place the bearing bush on the lower base of the bearing, aligning the oil filling hole 3 of the bearing bush with the hole on the upper cover of the bearing seat. Then pass the shaft through the inner hole of the bearing bush and install it in place. After that, install the upper part of the bearing seat and then tighten the upper and lower bearing seats with connecting bolts to fix the bearing bush.

[0040] Fifth step: Manually rotate the shaft to adjust the gap between the shaft and the bearing bush. Adjust the concentricity of the bearing bush and the shaft by adjusting the tightness of the connecting bolts and other measures until the adjustment is qualified.

[0041] The sixth step is to add lubricating oil into the bearing bush through the oil cup, check the equipment before operation, and finally conduct a trial run.

[0042] 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.
