Description

Technical Field

[0001] This utility model belongs to the field of bearing ring equipment, and in particular relates to a bearing ring. Background Technology

[0002] Bearing rings, as important components of radial rolling bearings, have one or more raceways. To ensure smooth bearing operation, lubricating oil is injected into the bearing. To prevent oil leakage, oil filling holes are usually provided on the bearing rings, and some bearings also have sealing plugs at these holes. However, currently, with bearing rings having sealing plugs at the oil filling holes, oil filling requires removing the plugs and directly injecting oil into the holes. But removing the plugs can easily cause them to roll off, collect dust, or even be lost. Utility Model Content

[0003] In view of this, the present invention aims to overcome the limitations of the prior art by proposing a bearing ring.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A bearing ring includes a bearing ring body with an annular limiting groove on the inner side of the bearing ring body. Multiple mounting holes are evenly formed on the outer circumferential surface of the bearing ring body, and the mounting holes are connected to the limiting groove. A sealing element is provided in each mounting hole. Each sealing element has an oil passage and an oil injection passage inside. The bottom opening of the oil passage is located at the bottom side wall of the sealing element, and the upper opening of the oil injection passage is located at the upper part of the side wall of the sealing element. The oil injection passage and the oil passage are connected. The upper opening of the oil injection passage is covered inside the mounting hole.

[0006] Furthermore, the top of the mounting hole is provided with a first limiting groove, and the bottom is provided with a second limiting groove. The first limiting groove, the second limiting groove and the mounting hole are connected. The top of the sealing block is provided with a connecting cap integrally formed with the sealing block, and the bottom is screwed with an annular limiting platform. The connecting cap is located in the first limiting groove and protrudes from the first limiting groove. The limiting platform is located in the second limiting groove.

[0007] Furthermore, a horizontal insertion hole is provided at the upper part of the connector cap where it protrudes from the first limiting groove, penetrating the interior of the connector cap.

[0008] Furthermore, the distance from the limiting platform to the second limiting groove is greater than the distance from the upper opening of the oil injection channel to the first limiting groove.

[0009] Furthermore, the sealing block is provided with a sealing groove, and a sealing ring is fitted inside the sealing groove. The sealing ring is located on the upper side of the opening at the upper end of the oil injection channel and is located inside the mounting hole.

[0010] Furthermore, an annular groove is formed on the outer circumferential surface of the bearing ring body, a first limiting groove is located in the groove, and a slanted groove is formed at the bottom of the groove that is connected to the corresponding oil injection channel side on the first limiting groove.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] The bearing ring of this invention has multiple mounting holes on its surface. Each mounting hole is sealed by a sealing block. An oil injection channel and an oil passage are provided within the sealing block. When oil injection is required, the sealing block is pulled outwards, exposing the upper opening of the oil injection channel on the surface of the bearing ring. Oil can then be injected through this opening, and the lubricating oil enters the bearing interior via the oil injection channel and the oil passage. This design eliminates the need to completely remove the sealing block during oil injection, effectively preventing its loss and providing a effective seal against dust at the oil injection port.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] As shown in the figure, a bearing ring includes a bearing ring body 1. An annular limiting groove 11 is provided on the inner side of the bearing ring body 1. Multiple mounting holes 12 are evenly opened on the outer circumferential surface of the bearing ring body 1, and the mounting holes 12 are connected to the limiting groove 11. A sealing element 2 is provided in each mounting hole 12. Each sealing element 2 has an oil passage 21 and an oil injection channel 22 inside. The bottom opening of the oil passage 21 is located at the bottom side wall of the sealing block, and the upper opening of the oil injection channel 22 is located at the upper part of the side wall of the sealing block. The oil injection channel 22 and the oil passage 21 are connected and arranged in a continuous manner. The upper opening of the oil injection channel 22 is covered inside the mounting hole 12. In this embodiment, multiple mounting holes 12 are provided on the surface of the bearing ring body 1. Each mounting hole 12 is sealed by a sealing block. An oil injection channel 22 and an oil passage 21 are provided in the sealing block. When oil injection is required, the upper opening of the oil injection channel 22 is exposed on the surface of the bearing ring body 1 when the sealing block is pulled outward. Oil can then be injected at the upper opening of the oil injection channel 22. The lubricating oil enters the bearing through the oil injection channel 22 and the oil passage 21.

[0026] The mounting hole 12 has a first limiting groove 121 at the top and a second limiting groove 122 at the bottom. The first limiting groove 121, the second limiting groove 122 and the mounting hole 12 are connected. The top of the sealing block has a connecting cap 23 integrally formed with the sealing block, and the bottom is screwed with an annular limiting platform 3. The connecting cap 23 is located in the first limiting groove 121 and protrudes from the first limiting groove 121. The limiting platform 3 is located in the second limiting groove 122. In this embodiment, the first limiting groove 121 is located on the outer circumferential surface of the bearing ring body 1, and the second limiting groove 122 is located at the limiting groove 11. In this embodiment, the connecting cap 23 is embedded in the first limiting groove 121, which is equivalent to setting a step on the upper side of the mounting hole 12, and the connecting cap 23 covers it, thereby enhancing the dustproof effect at the mounting hole 12.

[0027] The upper part of the connecting cap 23 has a horizontally protruding insertion hole 231 that penetrates the interior of the connecting cap 23 at the first limiting groove 121. The insertion hole 231 is provided for moving the sealing block outward. By inserting one end of the auxiliary rod into the insertion hole 231 and pulling the auxiliary rod upward, the sealing block can be moved outward.

[0028] The distance from the limiting platform 3 to the second limiting groove 122 is greater than the distance from the upper opening of the oil injection channel 22 to the first limiting groove 121. When the sealing block is pulled up, it ensures that the upper opening of the oil injection channel 22 is fully exposed, which facilitates the injection of lubricating oil and ensures that the sealing block does not come off the mounting hole 12, thus preventing the sealing block from being lost.

[0029] The sealing block is provided with a sealing groove 24, and a sealing ring 4 is fitted inside the sealing groove 24. The sealing ring 4 is located on the upper side of the upper opening of the oil injection channel 22 and inside the mounting hole 12. The sealing ring 4 seals the sealing block and the mounting hole 12 at the upper side of the upper opening of the oil injection channel 22, further preventing dust from entering the upper opening of the oil injection channel 22.

[0030] An annular groove 13 is formed on the outer circumferential surface of the bearing ring body 1. A first limiting groove 121 is located in the groove 13, and a beveled groove 14 is formed at the bottom of the groove 13, which is connected to the side of the corresponding oil injection channel 22 on the first limiting groove 121. In this embodiment, the beveled groove 14 is provided so that when the sealing block is moved upward to expose the upper opening of the oil injection channel 22, oil is injected into the oil injection channel 22. When injecting oil, the oil nozzle can be tilted at the beveled groove 14, which makes it easier to inject oil into the oil injection channel 22.

[0031] In this embodiment, the length direction of the insertion hole 231 corresponds to the circumferential direction of the groove 13, which facilitates the operation of the auxiliary rod.

[0032] The working process of this embodiment is as follows:

[0033] Insert the auxiliary rod into the insertion hole 231 and pull the auxiliary rod upward to move the sealing block outward. Once the upper opening of the oil injection channel 22 is exposed, remove the auxiliary rod and then inject oil into the oil injection channel 22. When injecting oil, the oil nozzle can be tilted at the oblique groove 14 to facilitate oil injection into the oil injection channel 22. The lubricating oil enters the bearing through the oil injection channel 22 and the oil passage 21. Finally, press the sealing block downward to allow the upper opening of the oil injection channel 22 to enter the mounting hole 12, and the sealing ring 4 seals the sealing block and the mounting hole 12.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
