Description

Technical Field

[0001] This utility model relates to the field of spherical bearing technology, specifically a multi-layer composite buffer spherical bearing. Background Technology

[0002] Special spherical bearings that combine multi-layer composite materials and buffer structures are designed to effectively absorb impact energy and reduce vibration and wear while bearing high loads through the synergistic effect of materials and structure.

[0003] For example, patent publication number CN218882790U discloses a spherical bearing with a metal buffer ring. The spherical bearing includes an outer ring, an inner ring, a bushing, and a buffer ring. The inner ring is fitted outside the bushing, and the buffer ring is positioned between the inner ring and the bushing. The inner ring, buffer ring, and bushing rotate synchronously. The buffer ring is made of woven and pressed wire-like metal material. The aforementioned spherical bearing has excellent damping and shock absorption effects, improving the reliability of the vehicle suspension system and the smoothness of the vehicle's ride, and effectively reducing the vibration and noise of the vehicle suspension system.

[0004] While the above solutions address the vibration damping issue, the following drawbacks remain: a self-lubricating PTFE bushing is typically installed between the inner and outer rings. During bearing operation, especially under extreme conditions, the bushing may detach from the outer ring, leading to failure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-layer composite buffer joint bearing to prevent the self-lubricating bushing from detaching from the outer ring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite buffer joint bearing, comprising an outer ring, an inner ring connected within the outer ring, and a bushing connected between the outer ring and the inner ring. Anti-detachment covers are connected to both sides of the outer ring, the inner walls of the two anti-detachment covers abut against the outer wall of the bushing, and a limit strip is fixedly connected to the back of the two anti-detachment covers. A limit groove corresponding to the position of the limit strip is opened on the inner wall of the outer ring.

[0007] Furthermore, the anti-detachment cover is composed of a first half-ring and a second half-ring, which are symmetrically arranged. Both ends of the first half-ring are fixedly connected to a mounting plate, and the ends of the second half-ring are provided with stepped grooves corresponding to the mounting plates. The bottom surface of the stepped groove is provided with a slot, and a limiting block fixedly connected to the bottom surface of the mounting plate is inserted into the slot. The outer side of the mounting plate is threaded with a bolt, and one end of the bolt passes through the mounting plate, the limiting block and is threadedly connected to the second half-ring.

[0008] Furthermore, the top surface of the bolt is lower than the top surface of the mounting plate.

[0009] Furthermore, the top surface of the bolt is provided with multiple anti-loosening grooves, the second half-ring is provided with a telescopic groove, a T-shaped telescopic rod is slidably connected in the telescopic groove, a connecting plate is fixedly connected to the end of the T-shaped telescopic rod, and an anti-loosening rod that is inserted into the anti-loosening groove is fixedly connected to the bottom surface of the end of the connecting plate.

[0010] Furthermore, a spring is connected inside the telescopic groove, and the top of the spring abuts against the bottom surface of the T-shaped telescopic rod.

[0011] Furthermore, the cross-section of the anti-detachment rod and the anti-detachment groove is rectangular.

[0012] Furthermore, the slot and the limiting block have rectangular cross-sections.

[0013] Furthermore, the connecting plate is embedded in the first half-ring and the second half-ring, and the second half-ring has an operating groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model uses two anti-detachment caps, which are positioned exactly on both sides of the bushing to block and limit its movement, ensuring its stability. The use of limiting strips and limiting grooves can also ensure the stability of the anti-detachment caps themselves.

[0016] This utility model sets two anti-detachment covers as a first half-ring and a second half-ring, making the installation of the anti-detachment covers simple and convenient. The use of a mounting plate, stepped groove and bolts can ensure that the first half-ring and the second half-ring are detachably connected, which is convenient for replacement and disassembly. The setting of slots and limit blocks can facilitate the positioning of the first half-ring and the second half-ring during installation, ensuring that the two do not shift.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 5 As shown, a multi-layer composite buffer spherical bearing includes an outer ring 1, an inner ring 2 connected inside the outer ring 1, and a bushing 4 connected between the outer ring 1 and the inner ring 2. Anti-detachment covers 3 are connected to both sides of the outer ring 1. The inner walls of the two anti-detachment covers 3 abut against the outer wall of the bushing 4. Limiting strips 6 are fixedly connected to the back of the two anti-detachment covers 3. Limiting grooves 5 corresponding to the positions of the limiting strips 6 are opened on the inner wall of the outer ring 1.

[0025] like Figure 1 As shown, the multi-layer composite buffer spherical bearing in this invention is similar in structure to existing spherical bearings with metal buffer rings. For example, patent publication number CN218882790U discloses a spherical bearing with a metal buffer ring. The main improvement of this invention is to prevent the self-lubricating bushing from detaching from the outer ring. Figures 1 to 5 As shown, in use, the multi-layer composite buffer joint bearing of this utility model can be installed on both sides of the outer ring 1. During installation, the limiting strip 6 on the outer wall of the anti-detachment cover 3 can be engaged with the limiting groove 5 to ensure the stability of the anti-detachment cover 3, so that the anti-detachment cover 3 is stably located on both sides of the outer wall of the bushing 4, and the bushing 4 is stably limited to ensure that the bushing 4 will not detach from the outer ring 1 and the inner ring 2.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the anti-detachment cover 3 is composed of a first half-ring 31 and a second half-ring 32. The first half-ring 31 and the second half-ring 32 are symmetrically arranged. Both ends of the first half-ring 31 are fixedly connected to a mounting plate 10. The ends of the second half-ring 32 are provided with stepped grooves 7 corresponding to the mounting plate 10. The bottom surface of the stepped groove 7 is provided with a slot 8. A limiting block 16 fixedly connected to the bottom surface of the mounting plate 10 is inserted into the slot 8. A bolt 9 is threadedly connected to the outer side of the mounting plate 10. One end of the bolt 9 passes through the mounting plate 10, the limiting block 16 and is threadedly connected to the second half-ring 32.

[0027] Specifically, when installing the anti-detachment cover 3, the second half ring 32 can be installed on the outer ring 1 first, and then the first half ring 31 can be installed on the outer ring 1, so that the mounting plate 10 on the first half ring 31 corresponds to the stepped groove 7, and the limiting block 16 is inserted into the slot 8. Then, the bolt 9 is threaded through the mounting plate 10, the limiting block 16 and the second half ring 32.

[0028] By setting the two anti-detachment covers 3 as the first half-ring 31 and the second half-ring 32, the anti-detachment covers 3 are easy and convenient to install. The mounting plate 10, the step groove 7 and the bolt 9 can ensure that the first half-ring 31 and the second half-ring 32 are detachably connected, which is convenient for replacement and disassembly. The slot 8 and the limiting block 16 can facilitate the positioning of the first half-ring 31 and the second half-ring 32 during installation, ensuring that the two do not shift.

[0029] like Figure 4 As shown, the top surface of bolt 9 is lower than the top surface of mounting plate 10. This design prevents the top surface of bolt 9 from protruding from mounting plate 10, thus preventing friction on the installed equipment.

[0030] like Figure 3 and Figure 4 As shown, the top surface of the bolt 9 is provided with multiple anti-detachment grooves 11, the second half ring 32 is provided with a telescopic groove 17, a T-shaped telescopic rod 14 is slidably connected in the telescopic groove 17, a connecting plate 13 is fixedly connected to the end of the T-shaped telescopic rod 14, and an anti-detachment rod 12 that is inserted into the anti-detachment groove 11 is fixedly connected to the bottom surface of the end of the connecting plate 13.

[0031] like Figure 3 and Figure 4 As shown, a spring 15 is connected inside the telescopic groove 17, and the top of the spring 15 abuts against the bottom surface of the T-shaped telescopic rod 14.

[0032] Specifically, after bolt 9 is installed, pull the anti-loosening rod 12 to rotate to the top of bolt 9. When the anti-loosening rod 12 rotates, it can drive the T-shaped telescopic rod 14 to rotate in the telescopic groove 17. Since the spring 15 only abuts against the bottom surface of the T-shaped telescopic rod 14, the T-shaped telescopic rod 14 can rotate. When the T-shaped telescopic rod 14 drives the connecting plate 13 and the anti-loosening rod 12 to the top of bolt 9, then under the action of the spring 15, the anti-loosening rod 12 will be inserted into the anti-loosening groove 11 and will always be located in the anti-loosening groove 11. This setting prevents the bearing from retracting due to vibration during use. By using the anti-loosening groove 11 and the anti-loosening rod 12 to limit the position of bolt 9, it is ensured that the position of bolt 9 will not loosen, thereby completely ensuring the stability between the first half ring 31 and the second half ring 32.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, the anti-detachment rod 12 and the anti-detachment groove 11 have rectangular cross-sections. The rectangular design of the anti-detachment rod 12 and the anti-detachment groove 11 makes the connection more stable.

[0034] like Figure 5 As shown, the slot 8 and the limiting block 16 have rectangular cross-sections. The rectangular design of the slot 8 and the limiting block 16 ensures good positioning.

[0035] like Figure 4 As shown, the connecting plate 13 is embedded in the first half-ring 31 and the second half-ring 32, and the second half-ring 32 has an operating groove 18. When it is necessary to remove the anti-detachment rod 12, the operating groove 18 can be operated with a tool to lift the T-shaped telescopic rod 14, thereby facilitating the removal of the anti-detachment rod 12.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
