Description

Technical Field

[0001] The utility model relates to the technical field of sprockets, in particular to an adjustable sprocket with good sealing performance. Background Art

[0002] As a wheel with cog-type sprocket teeth, sprockets are widely used in mechanical transmissions in many industries, including chemical industry, textile machinery, escalators, wood processing, agricultural machinery, food processing, etc. The performance of sprockets directly affects the stability and reliability of the transmission system. Therefore, there are strict requirements for the sealing performance of sprockets.

[0003] Common sealing issues with sprockets during use include oil seal failure and bearing damage. These problems not only lead to oil leaks and increased maintenance costs, but can also contaminate the transmission system, impacting normal operation. Furthermore, oil seal failure and bearing damage can shorten the sprocket's service life and reduce overall transmission system performance.

[0004] Although there are a variety of sprocket sealing technologies on the market, there are still some shortcomings. For example, some traditional sealing methods such as rotary oil seals have simple structures and low costs, but their sealing capabilities are limited and it is difficult to achieve an ideal sealing effect. Although floating seals have high sealing performance, their structures are relatively complex and have high requirements for rubber quality and supporting metal rings. In addition, some sealing methods also have problems such as inconvenient installation and difficult maintenance. For this reason, we propose an adjustable sprocket with good sealing performance.

The cover body 8 is clamped on the outer wall of one side of the sprocket 1, and the outer wall of one side of the cover body 8 is fixedly connected to the sunken buckle 9. An axial hole 10 is opened in the middle of the outer wall of one side of the cover body 8, and a sealing ring 11 is fixedly connected to the outer wall of one side of the cover body 8, and the concave groove 5 and the sealing ring 11 are mortise and tenon-jointed. A second screw hole 12 is opened on the side of the cover body 8 close to the sealing ring 11, and the second screw hole 12 is threadedly fitted with a bolt 13.

[0031] Furthermore, a bolt 13 is threadedly connected between the screw hole 7 and the second screw hole 12 .

[0032] Furthermore, the sprocket 1 is made of alloy steel.

[0033] Working principle: The sprocket 1 is the main component, and its inner wall is plugged with a sealed bearing 3 to ensure that the sprocket can remain stable during rotation and reduce the possibility of oil leakage. The outer wall of one side of the sprocket 1 is fixed with a sealed shaft cover 2 by a snap-on method. The shaft cover includes a cover body 8, a sinking buckle 9, a shaft hole 10, a sealing ring 11 and a second screw hole 12. The sinking buckle 9 cooperates with the sinking groove 4 on the sprocket 1 to ensure that the sealed shaft cover 2 can be firmly fixed on the sprocket 1. The sealing groove 6 on the inner wall of the sprocket 1 forms a mortise and tenon fit with the sealing ring 11. This structural design increases the sealing between the sealing shaft cover 2 and the sprocket 1. The design of the concave groove 5 provides an additional sealing surface for the sprocket 1. To further prevent oil leakage, the bolt 13 firmly connects the sealing shaft cover 2 to the sprocket 1 through the screw hole 7 and the second screw hole 12, thereby enhancing the overall stability and sealing. The sprocket 1 is made of alloy steel to ensure its strength and wear resistance, and is suitable for various working environments. When the sprocket 1 rotates during operation, the sealed bearing 3 ensures the stable operation of the sprocket. At the same time, the sealing shaft cover 2 and the sealing ring 11 inside it are tightly combined with the concave groove 5 and the sealing groove 6 of the sprocket 1 to form an effective sealing system, which greatly reduces the possibility of oil leakage. This design makes the sprocket more stable during operation, while extending its service life and reducing maintenance costs.
