Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing technology, and in particular to a rolling bearing that is easy to install and disassemble. Background Technology
[0002] Rolling bearings are fundamental components in mechanical transmission systems. Their core function is to support rotating shafts and reduce frictional resistance during movement, ensuring smooth operation of equipment.
[0003] Currently, most bearings adopt an integral structure, requiring axial pressing or hammering into the journal and bearing housing during installation, and similarly requiring the application of a reverse axial force to push them out during disassembly. This assembly method easily leads to mechanical damage to the bearing itself and its adjacent components, especially in situations where space is limited or frequent disassembly and maintenance are required. It is difficult to operate, inefficient, and can easily affect the bearing's accuracy and service life.
[0004] To address the above issues, we have introduced a rolling bearing that is easy to install and disassemble. Utility Model Content
[0005] This utility model discloses a rolling bearing that is easy to install and disassemble, aiming to solve the technical problems in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A rolling bearing that is easy to install and disassemble includes:
[0008] Two symmetrically arranged shells;
[0009] Two symmetrically arranged inner liners are disposed inside the outer shell;
[0010] The first movable end is movably connected between one end of the two outer shells;
[0011] The second movable end is movably connected between one end of the two inner linings;
[0012] Both the first and second active ends are equipped with card plates;
[0013] The rotating part includes an outer ring and an inner ring arranged coaxially, and a rolling element disposed between the outer ring and the inner ring. Both the inner ring and the outer ring are provided with slots for cooperation with a retaining plate.
[0014] A limiting guide mechanism includes a limiting block disposed on the rotating part and a limiting groove disposed on the outer shell and the inner liner, wherein the limiting block and the limiting groove are slidably engaged to radially limit the rotating part;
[0015] A locking mechanism for locking the first movable end to the outer casing and the second movable end to the inner lining.
[0016] In a preferred embodiment, the locking mechanism includes:
[0017] Positioning grooves are formed at the ends of the outer shell and the inner liner;
[0018] A positioning protrusion is symmetrically fixedly connected to the first movable end and the second movable end, and the positioning protrusion can slide into the positioning groove;
[0019] A locking screw passes through the positioning protrusion and secures the positioning protrusion in the positioning groove.
[0020] In a preferred embodiment, the limiting guide mechanism includes:
[0021] Equidistant limiting blocks fixed to the outer ring;
[0022] The outer limiting block is slidably connected to the inner limiting groove on the inner wall of the outer shell, and the inner limiting groove is equidistantly formed with the inner limiting groove.
[0023] Inner limiting blocks are equidistantly fixed on the inner ring;
[0024] An outer limiting groove is equidistantly formed on the outer side of the inner liner, and the inner limiting block is slidably connected to the outer limiting groove.
[0025] In a preferred embodiment, the rolling element is a ball bearing.
[0026] In a preferred embodiment, the end of the locking screw is provided with a hexagonal groove.
[0027] The rolling bearing provided by this utility model, which is easy to install and disassemble, has the following advantages:
[0028] This invention achieves radial installation and disassembly of the rotating part by employing a split outer shell and inner liner structure, combined with a retaining plate and slot mechanism located on the movable end and bearing ring. This avoids the axial hammering or pressing operations required for bearings and adjacent components in traditional installation methods, significantly reducing installation difficulty and the risk of component damage. During disassembly, there is no need to axially hammer the bearing; even if the outer shell or inner liner fits tightly with the connecting parts, it can be operated with a pulling tool. Furthermore, the pulling process does not affect the rotating parts of the bearing, thus simplifying the disassembly process and effectively avoiding damage to the bearing.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0035] This utility model discloses a rolling bearing that is easy to install and disassemble.
[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rolling bearing that is easy to install and disassemble includes:
[0037] Two symmetrically arranged outer shells 1;
[0038] Two symmetrically arranged inner liners 2 are disposed inside the outer shell 1;
[0039] The first movable end 3 is movably connected between one end of the two outer shells 1;
[0040] The second movable end 4 is movably connected between one end of the two inner linings 2;
[0041] Both the first active end 3 and the second active end 4 are equipped with card plates;
[0042] The rotating part includes an outer ring 5 and an inner ring 6 arranged coaxially, and a rolling element disposed between the outer ring 5 and the inner ring 6. Both the inner ring 6 and the outer ring 5 are provided with slots for cooperation with the card plate.
[0043] The limiting guide mechanism includes a limiting block disposed on the rotating part and a limiting groove disposed on the outer shell 1 and the inner liner 2. The limiting block and the limiting groove are slidably engaged so that the rotating part is radially limited.
[0044] A locking mechanism is used to lock the first movable end 3 to the outer shell 1 and the second movable end 4 to the inner liner 2;
[0045] In this embodiment: During installation, firstly, the two outer shells 1 are installed into the bearing housing. Then, the independent rotating part is radially inserted between the two fixed outer shells 1, and radial positioning is achieved through the limiting and guiding mechanism. Next, the two outer shells 1 are connected by the first movable end 3 to form a whole. Subsequently, the two inner liners 2 are connected by the second movable end 4 and fixed as a whole to the rotating shaft, making the inner liners 2 a single unit. Finally, the inner liners 2 are inserted into the inner ring 6 of the rotating part for stable placement.
[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the locking mechanism includes:
[0047] Positioning grooves 12 are provided at the ends of the outer shell 1 and the inner liner 2;
[0048] The positioning protrusions 13 are symmetrically fixedly connected to the first movable end 3 and the second movable end 4, and the positioning protrusions 13 can slide into the positioning groove 12;
[0049] The locking screw 14 passes through the positioning protrusion 13 and fastens the positioning protrusion 13 into the positioning groove 12;
[0050] In this embodiment: When closure is required, the positioning protrusions 13 on the first movable end 3 and the second movable end 4 slide into the positioning grooves 12 at the ends of the outer shell 1 and the inner liner 2, achieving initial alignment and closing. After tightening the locking screw 14, the pulling force generated by the screw pulls the positioning protrusions 13 towards the bottom of the positioning groove 12, and the two parts of the outer shell 1 or the inner liner 2 are tightly locked into a rigid whole by friction. At the same time, the locking plate also slides into the locking groove, thus limiting the rotating part and preventing it from detaching from the outer shell 1 and the inner liner 2. During disassembly, simply loosening the screw releases the locking and limiting functions.
[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in a preferred embodiment, the limiting guide mechanism includes:
[0052] Outer limiting blocks 8 are equidistantly fixed on the outer ring 5;
[0053] An inner limiting groove 11 is equidistantly formed on the inner wall of the outer shell 1, and an outer limiting block 8 is slidably connected to the inner limiting groove 11.
[0054] Inner limit blocks 9 are equidistantly fixed on the inner ring 6;
[0055] An outer limiting groove 10 is equidistantly opened on the outer side of the inner liner 2, and the inner limiting block 9 is slidably connected to the outer limiting groove 10;
[0056] In this embodiment, during the insertion of the rotating part into the outer casing 1, the outer limiting block 8 on the outer ring 5 will embed into the inner limiting groove 11 on the inner wall of the outer casing 1 and slide downwards. Similarly, the outer limiting groove 10 on the outer side of the inner liner 2 will align and engage with the inner limiting block 9 on the inner ring 6. This allows the rotating part to slide smoothly to the installation position during installation without requiring precise manual alignment, and prevents relative rotation between the outer ring 5 and the outer casing 1, and between the inner ring 6 and the inner liner 2, ensuring reliable torque transmission.
[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the rolling element is a ball bearing 7;
[0058] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the end of the locking screw 14 is provided with a hexagonal groove 15;
[0059] In this embodiment, the hexagonal groove 15 at the end of the locking screw 14 can be used with a common hex wrench.
[0060] Working principle: During installation, firstly, two symmetrically arranged outer shells 1 are placed inside the equipment bearing seat. Then, the rotating part is radially inserted between the two outer shells 1. During this process, the outer limiting block 8 fixed on the outer ring 5 slides along the inner limiting groove 11 on the inner wall of the outer shell 1, realizing the radial guidance and initial positioning of the rotating part. Subsequently, the two outer shells 1 are connected through the first movable end 3, so that the positioning protrusion 13 on it slides into the positioning groove 12 at the end of the outer shell 1. At this time, the retaining plate on the first movable end 3 is embedded in the corresponding retaining groove of the outer ring 5. Then, the locking screw 14 is tightened to lock the first movable end 3 and the outer shell 1 into one piece.
[0061] Next, the two inner liners 2 are connected into a ring structure through the second movable end 4 and fitted onto the shaft. Then, the combination of the shaft and the inner liners 2 is inserted axially into the inner ring 6 of the rotating part, so that the outer limiting groove 10 on the outer side of the inner liners 2 engages with the inner limiting block 9 on the inner ring 6 to achieve circumferential limiting. Finally, the second movable end 4 is closed and locked, and the locking plate on the movable end is embedded in the locking groove of the inner ring 6, thereby completing the overall installation of the bearing.
[0062] During disassembly, first loosen and open the second movable end 4 to separate the inner liner 2 from the inner ring 6, then move the shaft and inner liner 2 out together, then loosen the locking screw 14 of the first movable end 3, open the outer casing 1, and the rotating part can be taken out radially.
[0063] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
