Description

Technical Field

[0001] This utility model relates to the field of mechanical bearing technology, and in particular to an outer spherical ball bearing. Background Technology

[0002] Bearings are used to support rotating parts in mechanical equipment, reduce friction, improve efficiency, and support loads. Their working principle is to use the rolling motion of rolling elements between the inner and outer rings to reduce the contact area and friction, allowing the bearing to operate smoothly. When the rolling elements roll between the inner and outer rings, only a small area of ​​contact bears the pressure, which greatly reduces the contact area and thus reduces friction. Bearings are classified into deep groove ball bearings, angular contact ball bearings, thrust ball bearings, and spherical roller bearings.

[0003] The characteristic of spherical roller bearings is that the spherical shape of the outer ring allows the bearing to automatically adjust to maintain normal operation even if there are certain axial or radial errors during installation. This type of bearing is particularly suitable for applications with less stringent installation requirements. However, it often encounters relatively dirty environments, which can cause dirt to accumulate at the lubricating oil supply points. This can easily lead to the lubricating oil supply pipes coming loose during lubricating oil delivery, resulting in resource waste. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an external spherical ball bearing, which aims to improve the problem of external spherical ball bearings affecting the delivery of lubricating oil in dirty environments to achieve better use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outer spherical ball bearing, comprising a housing, with balls rotatably connected inside the housing, an inner shaft rotatably connected to the inner wall of the housing, the outer wall of the balls fitting against the outer wall of the inner shaft, a retaining ring fixedly connected to the outer wall of the inner shaft, the outer wall of the retaining ring rotatably connected to the inner wall of the housing, a delivery pipe fixedly connected to the upper surface of the housing, a threaded ring fixedly connected to the outer wall of the delivery pipe, a sealing cap threadedly connected to the outer wall of the threaded ring, a spring fixedly connected to the inner wall of the delivery pipe, a retaining ball fixedly connected to the outer wall of the spring, and a stabilizing component provided on the outer wall of the retaining ball, the stabilizing component being used to stabilize the bearing.

[0006] Preferably, the stabilizing component includes a fixing block, the outer wall of which is fixedly connected to the outer wall of the retaining bead, a base plate is fixedly connected to the lower surface of the fixing block, and the upper surface of the base plate is fixedly connected to the lower surface of the outer shell.

[0007] Preferably, a housing is fixedly connected inside the base plate, and a threaded rod is rotatably connected inside the housing.

[0008] Preferably, a handle is fixedly connected to the top end of the threaded rod, and a fixing plate is threadedly connected to the outer wall of the threaded rod.

[0009] Preferably, the outer wall of the fixing plate is slidably connected to the inner wall of the housing, and a stop block is fixedly connected to the outer wall of the fixing plate.

[0010] Preferably, the housing has a fixing groove inside and a rotating shaft inside.

[0011] Preferably, both ends of the rotating shaft are slidably connected to the inner wall of the fixed groove, and a vertical plate is rotatably connected to the outer wall of the rotating shaft.

[0012] Preferably, the lower surface of the upright plate is in contact with the upper surface of the stop block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the sealing cap is removed from the outer wall of the threaded ring by rotating it, and the pipe for adding lubricating oil is placed into the inner wall of the delivery pipe. At this time, the spring pushes the retaining ball to squeeze the pipe, which prevents the pipe from falling off and causing waste when adding lubricating oil. In addition, the sealing cap can prevent debris and dust from the outer wall from flying into the inner wall of the outer shell and affecting the lubrication, thereby enabling the bearing to achieve better performance.

[0015] 2. In this utility model, by inserting the housing into the structure to be installed, rotating the threaded rod causes the fixing plate to slide against the inner wall of the housing. As the stop slides, it pushes the upright plate upwards, simultaneously causing the rotating shaft to slide against the inner wall of the fixing groove. Furthermore, as the upright plate slides, it rotates against the outer wall of the rotating shaft, thus opening up and preventing the housing from detaching from the working area, achieving a better fixing effect.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of an outer spherical ball bearing, comprising a housing 1, with balls 2 rotatably connected inside the housing 1, and an inner shaft 3 rotatably connected to the inner wall of the housing 1. The outer walls of the balls 2 are in contact with the outer walls of the inner shaft 3. A fixing ring 4 is fixedly connected to the outer wall of the inner shaft 3, and the outer wall of the fixing ring 4 is rotatably connected to the inner wall of the housing 1. A conveying pipe 5 is fixedly connected to the upper surface of the housing 1, and a threaded ring 6 is fixedly connected to the outer wall of the conveying pipe 5. A sealing cap 7 is threadedly connected to the outer wall of the threaded ring 6. A spring 8 is fixedly connected to the inner wall of the conveying pipe 5, and a retaining ball 9 is fixedly connected to the outer wall of the spring 8. A stabilizing component is provided on the outer wall of the retaining ball 9 for stabilizing the use of the bearing. The stabilizing component includes a fixing block 10, the outer wall of the fixing block 10 is fixedly connected to the outer wall of the retaining ball 9, and a base plate 11 is fixedly connected to the lower surface of the fixing block 10. The upper surface of the base plate 11 is fixedly connected to the lower surface of the housing 1.

[0025] Specifically, the base plate 11 fixes the fixing block 10, which in turn fixes the outer casing 1 and prevents it from shifting. The ball bearing 2 allows for better rotation of the inner shaft 3 and the fixing ring 4. The delivery pipe 5 delivers lubricating oil to the interior of the outer casing 1. The spring 8 pushes the retaining ball 9 to move, which increases the friction between the lubricating oil and the pipe, preventing it from coming off. The delivery pipe 5 fixes the threaded ring 6, which connects to the sealing cap 7. The sealing cap 7 seals the delivery pipe 5 and the interior of the outer casing 1, preventing dust from entering and affecting the internal structure.

[0026] Reference Figure 1 , Figure 4 and Figure 5The base plate 11 is fixedly connected to the housing 12, and the housing 12 is rotatably connected to the threaded rod 19. The top of the threaded rod 19 is fixedly connected to the handle 13, and the outer wall of the threaded rod 19 is threadedly connected to the fixing plate 14. The outer wall of the fixing plate 14 is slidably connected to the inner wall of the housing 12, and the outer wall of the fixing plate 14 is fixedly connected to the stop block 15.

[0027] Specifically, the base plate 11 fixes the housing 12, the handle 13 drives the threaded rod 19 to rotate inside the housing 12, the threaded rod 19 drives the fixing plate 14 to slide on the inner wall of the housing 12, and the fixing plate 14 drives the stop block 15 to move simultaneously.

[0028] Reference Figure 4 and Figure 5 The housing 12 has a fixed groove 16 inside and a rotating shaft 17 inside. Both ends of the rotating shaft 17 are slidably connected to the inner wall of the fixed groove 16, and the outer wall of the rotating shaft 17 is rotatably connected to a vertical plate 18. The lower surface of the vertical plate 18 is in contact with the upper surface of the stop block 15.

[0029] Specifically, the stop block 15 can push the upright plate 18 to slide on the inner wall of the housing 12. The fixing groove 16 inside the housing 12 can limit the rotating shaft 17 to prevent displacement. The rotating shaft 17 is used to limit the position of the upright plate 18 and facilitates the rotation and opening of the upright plate 18. The opening of the upright plate 18 can improve the stability of the installation.

[0030] Working principle: When this bearing is needed, the housing 12 inside the base plate 11 is first slid into the structure to be installed. After sliding in, rotating the housing 12 causes the threaded rod 19 to rotate inside the housing 12. When the threaded rod 19 rotates, it causes the fixing plate 14 on the outer wall to slide on the inner wall of the housing 12. When the fixing plate 14 slides, it causes the stop 15 on the outer wall to slide on the inner wall of the housing 12. When the stop 15 slides, it pushes the upright plate 18 upward. When the upright plate 18 moves upward, it causes the internal rotating shaft 17 to slide on the inner wall of the fixing groove 16 inside the housing 12. At the same time, the upright plate 18 will rotate on the outer wall of the rotating shaft 17 and unfold outward. When the upright plate 18 unfolds, it can achieve a more stable fixation of the base plate 11. When the bearing is used for a long time, the lubrication begins to decrease, which reduces the efficiency. At this point, the rotating sealing cap 7 is removed from the outer wall of the threaded ring 6 on the outer wall of the conveying pipe 5. The pipe for adding lubricating oil is then inserted into the inner wall of the conveying pipe 5. The spring 8 rebounds, pushing the retaining ball 9 to squeeze the pipe, preventing it from slipping out and falling off, thus ensuring more stable lubrication. After lubrication is complete, the sealing cap 7 is reconnected to the outer wall of the threaded ring 6, sealing the conveying pipe 5. This prevents external dust and debris from entering the interior of the outer casing 1 and affecting the lubrication inside. This bearing not only provides greater stability during lubrication, preventing the lubrication pipe from falling off and wasting lubricating oil, but also seals the lubrication point, preventing debris and dust from affecting the lubrication effect. Furthermore, it allows for quick fixation of the bearing, preventing it from falling off or shifting.

[0031] 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.
