Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to self-aligning roller bearings for elevators. Background Technology

[0002] Bearings are components in mechanical equipment used to support the rotating shafts of machinery. They allow the shafts to rotate freely within the bearings and withstand axial and radial loads. Elevators are vertical transportation devices with extremely high requirements for smoothness, safety, and reliability during operation. Elevator traction machines need to withstand significant radial and axial loads while ensuring smooth operation and low noise. To ensure that the bearings are always in optimal working condition and meet the load requirements of the elevator traction machine, self-aligning roller bearings for elevators are required.

[0003] Self-aligning roller bearings for elevators are roller bearings with self-aligning function. In the past, the bearings usually only had one set of rollers or balls inside, which made it difficult to automatically align. When the shaft deflected or there was an installation error, it may cause jamming, making it inconvenient to use. Utility Model Content

[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 Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an automatic self-aligning roller bearing for elevators, comprising a lower outer ring 1, a cage 4 disposed inside the lower outer ring 1, a limit frame 5 disposed inside the cage 4, a first roller 6 disposed inside the limit frame 5, a second roller 7 disposed inside the limit frame 5, an inner ring 2 disposed inside the cage 4, a support ring 3 fixedly connected to the outer wall of the inner ring 2, the upper surface of the support ring 3 being slidably connected to the lower surface of the first roller 6, the lower surface of the support ring 3 being slidably connected to the upper surface of the second roller 7, and a limit component disposed on the upper surface of the lower outer ring 1.

[0025] Specifically, the lower outer ring 1 is the outermost structure of the bearing, which provides support and protection. Inside the lower outer ring 1, there is a cage 4, and inside the cage 4, there is a limit frame 5. The cage 4 supports the internal structure of the bearing. The limit frame 5 limits the movement of roller 6 and roller 7. Roller 6 is installed in the limit frame 5 above the cage 4, and roller 7 is installed in the limit frame 5 below the cage 4. Roller 6 and roller 7 have a certain tilt angle inside the cage 4, which can play a role in self-alignment. Inside the cage 4, there is an inner ring 2. The outer wall of the inner ring 2 is provided with a support ring 3. The support ring 3 supports and limits roller 6 and roller 7 to maintain their stability.

[0026] Reference Figure 4 The limiting component includes an upper outer ring 8, the lower surface of the upper outer ring 8 is connected to the upper surface of the lower outer ring 1, the lower surface of the upper outer ring 8 is fixedly connected to a limiting post 9, and the outer wall of the limiting post 9 is slidably connected to the inside of the lower outer ring 1.

[0027] Specifically, the upper outer ring 8 serves to fix the limiting post 9. When the upper outer ring 8 and the lower outer ring 1 are assembled, the limiting post 9 can slide inside the lower outer ring 1, and the limiting post 9 plays a limiting role.

[0028] Reference Figure 4 and Figure 5 A locking plate 10 is fixedly connected to the lower surface of the upper outer ring 8, and the outer wall of the locking plate 10 is slidably connected to the inside of the lower outer ring 1. A locking block 11 is slidably connected to the outer wall of the locking plate 10, and a rotating shaft 12 is rotatably connected to the inside of the locking block 11. The outer wall of the rotating shaft 12 is fixedly connected to the inside of the locking block 11. A fixing frame 13 is fixedly connected to the outer wall of the locking block 11, and a fixing shaft 14 is fixedly connected to the inside of the fixing frame 13. A rotating block 15 is rotatably connected to the outer wall of the fixing shaft 14, and a sliding column 16 is fixedly connected to the outer wall of the rotating block 15. The outer wall of the sliding column 16 is slidably connected to the inside of the lower outer ring 1. A sliding piece 17 is fixedly connected to the outer wall of the sliding column 16, and the outer wall of the sliding piece 17 is slidably connected to the inside of the lower outer ring 1. A spring 18 is provided on the outer wall of the sliding column 16, one end of the spring 18 is fixedly connected to the inside of the lower outer ring 1, and the other end of the spring 18 is fixedly connected to the outer wall of the sliding piece 17.

[0029] Specifically, the upper outer ring 8 fixes the clamping plate 10. By driving the clamping plate 10 to slide inside the lower outer ring 1, the sliding column 16 can drive the sliding piece 17 to slide inside the lower outer ring 1. The sliding piece 17 can drive the spring 18 to be compressed. The sliding column 16 can drive the rotating block 15 to move. When the rotating block 15 moves, it can drive the fixed shaft 14 to slide inside the rotating block 15. The fixed shaft 14 can drive the fixed frame 13 to move. The fixed frame 13 can drive the clamping block 11 to move. The clamping block 11 can slide on the outer wall of the rotating shaft 12 by rotating on the outer wall of the clamping plate 10. By driving the clamping plate 10 to slide out of the lower outer ring 1, the upper outer ring 8 can be quickly disassembled, which facilitates the assembly of the upper outer ring 8 and the lower outer ring 1.

[0030] Working principle: When this roller bearing is needed, it is first assembled. First, the inner ring 2 is installed inside the cage 4. Then, roller 6 is installed in the limiting frame 5 set above the cage 4, and roller 7 is installed in the limiting frame 5 set below the cage 4. The outer wall of the support ring 3 is in contact with roller 6 and roller 7. At this time, the cage 4 is installed inside the lower outer ring 1, which drives the upper outer ring 8 to contact the lower outer ring 1. At the same time, the limiting post 9 slides inside the lower outer ring 1. After the assembly is completed, the bearing is installed in the elevator equipment as required. The automatic self-aligning and bearing stability can be achieved by the clever tilt angle of roller 6 and roller 7.

[0031] When installing the upper outer ring 8 and the lower outer ring 1, the limiting post 9 is slid into the inside of the clamping plate 10, causing the clamping plate 10 to slide inside the lower outer ring 1. At the same time, pulling the sliding post 16 causes the sliding piece 17 to slide inside the lower outer ring 1, thereby compressing the spring 18, which in turn causes the rotating block 15 to move. Simultaneously, the rotating block 15 can rotate on the outer wall of the fixed shaft 14, thereby causing the fixed frame 13 to move. At the same time, the clamping block 11 can rotate on the outer wall of the rotating shaft 12. At this time, by causing the clamping plate 10 to slide out of the outer wall of the upper outer ring 8, the upper outer ring 8 can be quickly disassembled. This bearing can not only achieve the effect of automatic self-alignment of the bearing and improve the stability of the bearing, but also achieve the effect of quick disassembly of the upper outer ring 8.

[0032] 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.
