Technical Field

[0001] This utility model relates to the technical field of ball bushing assemblies, and in particular to a ball bushing assembly that is easy to assemble. Background Technology

[0002] A ball bushing assembly is a mechanical component used to support and guide shafts or rotating parts. Its core structure includes an inner bushing, an outer bushing, and balls arranged between them. The balls are secured between the inner and outer bushings by evenly spaced cages, allowing the rotating parts to operate smoothly under low friction, thereby improving the accuracy and service life of the mechanical system. This assembly typically offers advantages such as easy installation, high load-bearing capacity, and low frictional resistance, and can be widely used in machining equipment, automated devices, and various rotating machinery to achieve stable and efficient power transmission and motion support.

[0003] In the existing technology, ball bushing assemblies are inconvenient to disassemble and assemble during use, especially when there are a large number of balls or they are densely arranged. Disassembling and replacing balls requires a lot of time and space, and improper operation can easily lead to ball loss, raceway damage or component deformation, thereby affecting the service life of the bushing and the operating efficiency of the mechanical equipment, and increasing maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ball bushing assembly that is easy to assemble, aiming to improve the problem of inconvenient disassembly and assembly of ball bushing assemblies in the prior art during use.

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

[0006] A ball bearing bushing assembly that is easy to assemble includes a bushing body, a mounting bracket is fitted on the outer side of the bushing body, and multiple sets of balls are mounted on the surface of the mounting bracket. An outer sleeve is fitted on the outer side of the mounting bracket.

[0007] By adopting the above technical solutions, the bushing body serves as the core support for the shaft or rotating component, bearing sliding loads. Multiple sets of balls on the outer side of the mounting bracket form a rolling contact surface between the bushing body and the outer sleeve, facilitating the rotation and sliding of the outer sleeve, significantly reducing frictional resistance and improving the smoothness and accuracy of the motion.

[0008] Preferably, the lower end of the bushing body is provided with two sets of positioning plates, and the outer sides of the two sets of positioning plates are provided with multiple sets of locking strips, and the upper end of the inner side of the bushing body is provided with a matching fixing groove.

[0009] Preferably, the mounting bracket has multiple sets of sliding strips inside, and the bushing body has multiple sets of matching sliding grooves on its outer side.

[0010] Preferably, the mounting bracket has multiple sets of mounting grooves on its surface, and multiple sets of balls are rotatably installed in the mounting grooves. Limiting blocks are slidably installed inside the multiple sets of mounting grooves, and the side of the mounting groove that is close to the limiting block is provided with a structure that matches the balls.

[0011] Preferably, each of the multiple sets of limiting blocks is provided with an adjusting rod at one end that is far apart from the other, and the multiple sets of adjusting rods are respectively inserted into the upper and lower sides of the mounting frame through a threaded structure.

[0012] Preferably, lubrication grooves are provided on adjacent sides inside the multiple sets of mounting grooves, and the multiple sets of lubrication grooves are connected by two sets of connecting grooves.

[0013] Preferably, the bushing body, mounting bracket, and outer sleeve are all coated with a fluoropolymer coating.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting a limiting block and an adjusting rod, the ball is installed in the mounting groove, and then the adjusting rod is rotated so that the adjusting rod moves through the upper end of the threaded mounting groove, thereby driving the limiting block to move, restricting the ball between the mounting groove and the limiting block, which facilitates its rotation while preventing it from falling off, and makes it convenient to replace the ball.

[0016] 2. In this utility model, by providing sliding strips and sliding grooves, multiple sets of sliding strips inside the mounting bracket cooperate with multiple sets of matching sliding grooves on the outside of the bushing body, which can realize reliable guidance and smooth relative sliding between the bushing body and the mounting bracket, and facilitate the installation of the mounting bracket and the bushing.

[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] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a ball bushing assembly that is easy to assemble, including a bushing body 1, a mounting bracket 2 is sleeved on the outside of the bushing body 1, and multiple sets of balls 3 are mounted on the surface of the mounting bracket 2, and an outer sleeve 4 is sleeved on the outside of the mounting bracket 2.

[0026] Specifically, the bushing body 1 serves as the core support for the shaft or rotating component, bearing sliding loads. Multiple sets of balls 3 on the outer side of the mounting bracket 2 form a rolling contact surface between the bushing body 1 and the outer sleeve 4, facilitating the rotation and sliding of the outer sleeve 4, significantly reducing frictional resistance and improving the smoothness and precision of the motion.

[0027] Reference Figure 1 The lower end of the bushing body 1 is provided with two sets of positioning pieces 5, and the outer sides of the two sets of positioning pieces 5 are provided with multiple sets of locking strips 6, and the upper end of the bushing body 1 is provided with a matching fixing groove 7.

[0028] Specifically, the two sets of bushing bodies 1 can be connected by the cooperation of the positioning piece 5 and the fixing groove 7, and the bushing body 1 can be fixed by the clip 6.

[0029] Reference Figure 2 The mounting bracket 2 has multiple sets of sliding bars 8 inside, and the bushing body 1 has multiple sets of matching sliding grooves 9 on the outside.

[0030] Specifically, the multiple sets of sliding strips 8 inside the mounting bracket 2 cooperate with the multiple sets of matching sliding grooves 9 opened on the outside of the bushing body 1 to achieve reliable guidance and smooth relative sliding between the bushing body 1 and the mounting bracket 2. This ensures the stable rolling of the ball 3 during operation and prevents the components from shifting or shaking, thereby improving rolling accuracy and service life.

[0031] Reference Figure 3 The mounting bracket 2 has multiple mounting grooves 10 on its surface, and multiple sets of ball bearings 3 are rotatably installed in the mounting grooves 10. Limiting blocks 11 are slidably installed inside the multiple mounting grooves 10. The side of the mounting groove 10 that is close to the limiting block 11 is provided with a structure that matches the ball bearing 3. The side of the multiple limiting blocks 11 that is far away is provided with an adjusting rod 12. The multiple adjusting rods 12 are respectively inserted into the upper and lower sides of the mounting bracket 2 through a threaded structure.

[0032] Specifically, by installing the ball bearing 3 in the mounting groove 10, and then rotating the adjusting rod 12, the adjusting rod 12 moves at the upper end of the mounting groove 10 through the threaded structure, thereby driving the limiting block 11 to move. After the limiting block 11 moves to the appropriate position, it can just restrict the ball bearing 3 in the mounting groove 10 without affecting its rolling, which can facilitate the installation and removal of the ball bearing 3.

[0033] Reference Figure 4 and Figure 5 Each of the multiple mounting slots 10 has a lubrication slot 13 on one side that is close to each other, and the multiple lubrication slots 13 are connected by two connecting slots 14.

[0034] Specifically, the lubrication groove 13 and the connecting groove 14 can form a continuous lubrication channel, so that the grease or oil can be evenly distributed to the contact surface of the ball 3 with the bushing body 1 and the mounting bracket 2, thereby effectively reducing friction and wear, improving the smooth operation and service life of the components, simplifying lubrication maintenance, and ensuring stable and reliable rolling performance during long-term operation.

[0035] Reference Figure 1 The bushing body 1, mounting bracket 2 and outer sleeve 4 are all coated with fluoropolymer coating;

[0036] Specifically, the fluoropolymer coating can significantly reduce the coefficient of friction between the ball 3 and each contact surface, achieving a self-lubricating effect and thus reducing the dependence on external lubricants. The fluoropolymer coating has good corrosion resistance and wear resistance, which can extend the service life of the bushing assembly and improve the smoothness and reliability of operation, especially in high-speed or harsh environments, ensuring the stable operation of the assembly.

[0037] Working principle: As needed, multiple sets of bushing bodies 1 are installed through the cooperation of positioning pieces 5, retaining strips 6 and fixing grooves 7. Positioning pieces 5 are installed in fixing grooves 7 and then fixed by retaining strips 6. Then, the ball bearings 3 are installed in mounting grooves 10. By rotating adjusting rod 12, the limiting block 11 is moved to the upper side of the ball bearings 3, restricting the ball bearings 3 in the mounting grooves 10, which facilitates the installation and removal of the ball bearings 3. Then, mounting bracket 2 is fitted on the outside of bushing body 1 through the cooperation of sliding strip 8 and sliding groove 9. Then, outer sleeve 4 is fitted on the outside of mounting bracket 2.

[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.
