Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a linear bearing with directional positioning installation. Background Technology

[0002] Bearings are a very important component in mechanical equipment. By using bearings, rotating bodies can be stably supported, while the coefficient of friction can be reduced. There are many types of bearings, among which linear bearings are more common. A linear bearing is a linear motion system used in conjunction with a cylindrical shaft for linear travel.

[0003] Linear bearings typically have deep housings, making positioning difficult. Furthermore, the outer diameter of the linear bearing is an transition fit with the housing, while the control shaft and the inner diameter are an interference fit. In addition to reciprocating linear motion, the control shaft also rotates at a certain angle. Therefore, under heavy loads or after prolonged operation, linear bearings are prone to wear. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a linear bearing with directional positioning installation. This solves the problem that existing bearings generally require positioning during assembly. The existing method of positioning bearings involves directly connecting them tightly using a sealing ring. When the bearing needs to be moved out for positioning, it requires external support for fixation. Furthermore, the smooth outer surface of the bearing makes subsequent positioning and assembly difficult, resulting in low assembly accuracy and high wear on the bearing.

[0005] The technical solution adopted by this utility model is as follows: a linear bearing with directional positioning installation, including a limiting seat, a locking element, a limiting element, and a bushing; the locking element is disposed at both ends of the limiting seat, and one end of the limiting element is sleeved on the bushing to limit the bushing; the bushing is disposed in the limiting seat, and the locking element is used to limit and lock the front and rear ends of the bushing; the bushing includes a fixed sleeve and a movable sleeve, and the movable sleeve is movably disposed in the fixed sleeve; a ball element is disposed inside the movable sleeve, and the locking element and the limiting element are used to limit and fix the fixed sleeve so that the ball element can be positioned and moved within the movable sleeve and the fixed sleeve.

[0006] A further improvement to the above solution is that the limiting seat is provided with mounting screw holes, and multiple sets of mounting screw holes are provided, with the multiple sets of mounting screw holes arranged opposite to each other.

[0007] A further improvement to the above scheme is that the limiting seat is provided with a cavity, the bushing is disposed in the cavity, the limiting seat is provided with a limiting groove and a locking groove on the side near the cavity, the limiting element is disposed in the limiting groove, and the locking element is disposed in the locking groove.

[0008] A further improvement to the above scheme is that the limiting groove and the cavity are disposed on the limiting ring, and the limiting ring is used to limit the limiting element and the bearing.

[0009] A further improvement to the above solution is that the locking element includes a locking ring and locking protrusions, and the locking protrusions are provided in two sets, which are respectively disposed at both ends of the locking ring.

[0010] A further improvement to the above scheme is that the locking protrusion is provided with a locking hole, which is located at one end of the bushing near the limiting element.

[0011] A further improvement to the above solution is that the limiting element includes a limiting sleeve, the two ends of the limiting sleeve are provided with limiting portions, the limiting sleeve is provided with a limiting groove near the limiting portion, and an elastic ring is provided in the limiting sleeve near the limiting groove. The elastic ring is used to limit the bearing and the limiting seat.

[0012] A further improvement to the above solution is that the movable sleeve is provided with multiple movable grooves, which are arranged around the inner wall of the movable sleeve.

[0013] A further improvement to the above solution is that the movable groove is U-shaped, and multiple ball bearing elements are provided, which are evenly distributed within the movable sleeve and move along the movable groove.

[0014] A further improvement to the above scheme is that the ball element is a steel ball, a stainless steel ball, a ceramic ball, a plastic ball, or an alloy ball.

[0015] The beneficial effects of this utility model are:

[0016] Compared to existing bearings, this invention features locking elements meticulously positioned at both ends of the limiting seat, ensuring precise locking of the bushing in the front-to-back direction. This effectively prevents accidental displacement or wobbling. The movable sleeve's ability to move freely within the fixed sleeve enhances the bearing's flexibility and allows the entire system to operate more smoothly under load. The ball bearing elements inside the movable sleeve enable precise positioning, significantly reducing frictional resistance, improving bearing efficiency and smoothness, and minimizing frictional loss. The locking and limiting elements work together on the fixed sleeve to ensure stable operation of the ball bearing elements. The design is compact, easy to operate, and guarantees high-precision positioning of the bearing in linear motion while achieving efficient energy transfer and load support, making it highly practical.

[0029] like Figure 1-4As shown in the embodiment of this utility model, a linear bearing with directional positioning installation includes a limiting seat 10, a locking element 20, a limiting element 30, and a bushing 40. The locking element 20 is disposed at both ends of the limiting seat 10, and one end of the limiting element 30 is sleeved on the bushing 40 to limit the bushing 40. The bushing 40 is disposed inside the limiting seat 10, and the locking element 20 is used to limit and lock the front and rear ends of the bushing 40. The bushing 40 includes a fixed sleeve 41 and a movable sleeve 42, and the movable sleeve 42 is movably disposed inside the fixed sleeve 41. A ball element 50 is disposed inside the movable sleeve 42, and the locking element 20 and the limiting element 30 are used to limit and fix the fixed sleeve 41 so that the ball element 50 can be positioned and moved within the movable sleeve 42 and the fixed sleeve 41. In this embodiment, the locking element 20 is carefully set at both ends of the limiting seat 10 to ensure that the bushing 40 is precisely limited and locked in the front-rear direction, effectively preventing accidental displacement or shaking. The movable sleeve 42 can move freely within the fixed sleeve 41, enhancing the flexibility of the bearing and enabling the entire system to operate more smoothly under load. The ball element 50 set inside the movable sleeve 42 can perform precise positioning, thereby greatly reducing frictional resistance, improving the bearing's operating efficiency and smoothness, and reducing frictional loss. The locking element 20 and the limiting element 30 work together on the fixed sleeve 41 to ensure the stable operation of the ball element 50. The structure is compact and easy to operate. It not only ensures high-precision positioning of the bearing in linear motion but also achieves efficient energy transfer and load support, making it highly practical.

[0030] like Figure 1 As shown, the limiting seat 10 is provided with mounting screw holes 11, and multiple sets of mounting screw holes 11 are provided, which are arranged opposite to each other. In this embodiment, multiple sets of mounting screw holes 11 provide diverse installation options, making it convenient for users to flexibly adjust the installation position and angle of the linear bearing according to actual needs, thereby enhancing the flexibility and adaptability of installation.

[0031] A cavity 12 is provided within the limiting seat 10, and the bushing 40 is disposed within the cavity 12. A limiting groove 13 and a locking groove 14 are provided on the side of the limiting seat 10 near the cavity 12. The limiting element 30 is disposed within the limiting groove 13, and the locking element 20 is disposed within the locking groove 14. In this embodiment, the cavity 12 is used to precisely position the bushing 40. The carefully designed limiting groove 13 and locking groove 14 on one side of the limiting seat 10 are used to install the limiting element 30 and the locking element 20, respectively. The limiting element 30 ensures stable movement of the bearing in a predetermined direction, effectively preventing offset. The locking element 20 further consolidates the installation position, enhancing the overall structural stability and reliability, improving the positioning accuracy of the linear bearing, and significantly enhancing its adaptability and durability in complex application environments.

[0032] The limiting groove 13 and the cavity 12 are disposed on the limiting ring 15, which is used to limit the positioning of the element 30 and the bearing. In this embodiment, the limiting ring 15 ensures that the bearing is positioned and installed in a predetermined direction during installation, effectively preventing misalignment or displacement of the bearing. The matching design of the limiting groove 13 and the cavity 12 simplifies the installation process, reduces maintenance costs, and provides solid technical support for linear bearings.

[0033] The locking element 20 includes a locking ring 21 and locking protrusions 22. Two sets of locking protrusions 22 are provided, respectively disposed opposite to each other at both ends of the locking ring 21. In this embodiment, the arrangement of two sets of locking protrusions 22 opposite to each other at both ends of the locking ring 21 not only enhances the symmetry of the structure but also ensures the balance and reliability of the locking action, enabling precise alignment and effectively avoiding misalignment or displacement, thereby improving installation accuracy and stability.

[0034] The locking protrusion 22 is provided with a locking hole 23, which is located near the limiting element 30 at one end of the bushing 40. In this embodiment, by carefully arranging the locking hole 23 at one end of the bearing, close to the limiting element 30, precise and stable positioning and installation are achieved. Through the cooperation of the locking hole 23 and the corresponding locking mechanism, it is ensured that the bearing can work stably in the predetermined direction after installation, effectively preventing unexpected displacement or rotation of the bearing during use, enhancing its operational stability and reliability, and providing a solid guarantee for the efficient and precise operation of the linear motion system.

[0035] The limiting element 30 includes a limiting sleeve 31, with limiting portions 32 at both ends. A limiting groove 13 is provided near the limiting portions 32 on the limiting sleeve 31, and an elastic ring 33 is disposed within the limiting groove 13 on the limiting sleeve 31. The elastic ring 23 is used to limit the bearing and the limiting seat 10. In this embodiment, the limiting portions 32 at both ends of the limiting sleeve 31 ensure precise positioning, and the elastic ring 23 within the limiting groove 13 effectively limits the bearing and the limiting seat 10. This enhances the directional positioning accuracy of the linear bearing during installation and improves the stability and flexibility of the installation through the adaptability of the elastic ring 23.

[0036] like Figures 2 to 3 As shown, the movable sleeve 42 is provided with multiple movable grooves 421, which are arranged around the inner wall of the movable sleeve 42. In this embodiment, by providing multiple annular movable grooves 421 on the movable sleeve 42, multi-point support and guidance for the linear bearing are achieved, increasing the adaptability of bearing installation and ensuring stable positioning at different installation angles.

[0037] The movable groove 421 is U-shaped, and multiple ball bearing elements 50 are provided. These ball bearing elements 50 are evenly distributed within the movable sleeve 42 and move along the movable groove 421. In this embodiment, the even distribution of multiple ball bearing elements 50 within the movable sleeve 42 ensures stable load distribution and smooth movement. Furthermore, the flexible rolling of the ball bearing elements 50 along the U-shaped movable groove 421 significantly reduces frictional resistance, improving the bearing's operating efficiency and precision.

[0038] The ball bearing element 50 can be made of steel, stainless steel, ceramic, plastic, or alloy. In this embodiment, steel balls possess high strength and wear resistance, making them suitable for high-load operation; stainless steel balls offer excellent corrosion resistance, making them suitable for harsh environments; ceramic balls have extremely high hardness and a low coefficient of friction, significantly improving operating accuracy and speed; plastic balls have good self-lubrication and low noise, making them suitable for light-load and noise-sensitive applications; and alloy balls combine the advantages of multiple metals, providing balanced performance. This ensures stable operation of the linear bearing, meets the needs of diverse mechanical systems, and improves overall work efficiency and reliability.

[0039] A linear bearing with directional positioning installation includes a limiting seat 10, a locking element 20, a limiting element 30, and a bushing 40. The locking element 20 is disposed at both ends of the limiting seat 10, and one end of the limiting element 30 is sleeved on the bushing 40 to limit the bushing 40. The bushing 40 is disposed within the limiting seat 10, and the locking element 20 is used to limit and lock the front and rear ends of the bushing 40. The bushing 40 includes a fixed sleeve 41 and a movable sleeve 42, and the movable sleeve 42 is movably disposed within the fixed sleeve 41. A ball element 50 is disposed inside the movable sleeve 42, and the locking element 20 and the limiting element 30 are used to limit and fix the fixed sleeve 41 so that the ball element 50 can be positioned and moved within the movable sleeve 42 and the fixed sleeve 41. In this embodiment, the locking element 20 is carefully set at both ends of the limiting seat 10 to ensure that the bushing 40 is precisely limited and locked in the front-rear direction, effectively preventing accidental displacement or shaking. The movable sleeve 42 can move freely within the fixed sleeve 41, enhancing the flexibility of the bearing and enabling the entire system to operate more smoothly under load. The ball element 50 set inside the movable sleeve 42 can perform precise positioning, thereby greatly reducing frictional resistance, improving the bearing's operating efficiency and smoothness, and reducing frictional loss. The locking element 20 and the limiting element 30 work together on the fixed sleeve 41 to ensure the stable operation of the ball element 50. The structure is compact and easy to operate. It not only ensures high-precision positioning of the bearing in linear motion but also achieves efficient energy transfer and load support, making it highly practical.
