[0001] The utility model relates to the technical field of auxiliary machine manufacturing of steam turbines, and particularly relates to a bearing seat with strong sealing performance. Background Technique

[0002] A bearing seat is an important mechanical component for supporting bearings. Its main function is to fix the outer ring of the bearing so that the inner ring can rotate, while keeping the outer ring consistent with the transmission direction and maintaining balance. Currently, the bearing seat is mainly composed of a series of components such as a split upper and lower seat bodies and bearing mounting holes. The upper seat body is usually designed with bearing mounting holes for accommodating and fixing the outer ring of the bearing. It usually has a precisely machined surface to ensure precise fit with the outer ring of the bearing. The lower seat body cooperates with the upper seat body to jointly form a complete bearing seat structure. However, most of the joints of the bearing seat do not have a sealing structure, which may lead to leakage of lubricant during operation and intrusion of external pollutants such as dust and moisture, thus affecting the operating performance and lifespan of the bearing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bearing seat with strong sealing performance to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A bearing seat with strong sealing performance, including a base.

The limiting structure is connected with the support plate one. A limiting groove is opened on one side of the top seat. The limiting structure is clamped in the limiting groove. The clamping structure includes a fixed column, a sleeve ring, and a fixed disk. An arc-shaped clamping plate is fixedly connected to the outer surface of the sleeve ring. A coil spring is sleeved outside the fixed column. The arc-shaped clamping plate is clamped inside the installation column.

[0005] As a further preference of this technical solution, the bearing ring is clamped inside the top seat. The top seat is connected to the base through bolts. The support plate one and the support plate two are overlapped.

[0006] As a further preference of this technical solution, the fixed column is fixedly connected to one side of the support plate one. The installation column is clamped inside the support plate one. The fixed disk is fixedly connected to one end of the fixed column.

[0012] (1) By providing a protective ring one, a protective ring two, a clamping structure, a support plate one, a support plate two and a mounting post, when the mounting post penetrates through the support plate one, a turning force is applied to the ferrule. When the ferrule rotates on the surface of the fixed column, the spiral spring will be deformed. When the support plate one and the support plate two are in contact, the ferrule is released. The ferrule will be reset by the action of the spiral spring, and the arc-shaped clamping plate will be clamped in the mounting post after the ferrule is reset. Through the cooperation between the arc-shaped clamping plate, the spiral spring and the mounting post, the protective ring one and the protective ring two can be quickly assembled with both sides of the base, avoiding the leakage of lubricant during the operation of the bearing seat and preventing the intrusion of external pollutants, thus ensuring the operation performance and service life of the bearing seat.

[0013] (2) By providing a limiting structure and a limiting groove, after the base and the top seat are connected, the protective ring one and the protective ring two are sleeved on the left and right sides of the base. When the protective ring one and the protective ring two are sleeved, the support plate one and the support plate two on the surface will come into contact. The support plate one will slide in the limiting groove through the positioning plate two, and the support plate two will slide in the limiting groove through the positioning plate one, so as to play a certain limiting role in the fixation of the protective ring one and the protective ring two, avoiding the phenomenon that the positions of the protective ring one and the protective ring two are offset during fixation.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figure 1 and Figure 4 shown, in this embodiment, a bearing seat with strong sealing performance includes a base 1. A top seat 2 is connected above the base 1. A bolt 3 is connected inside the top seat 2. A bearing ring 4 is connected inside the base 1. A first protective ring 5 is sleeved on the left side of the base 1. A second protective ring 6 is sleeved on the right side of the base 1. A first support plate 9 is fixedly connected to the outer surface of the first protective ring 5. A second support plate 10 is fixedly connected to the outer surface of the second protective ring 6. An installation column 11 is fixedly connected to one side of the second support plate 10. A clamping structure 7 is provided on one side of the first support plate 9. The clamping structure 7 is clamped with the installation column 11. A limiting structure 8 is connected to the outside of the second support plate 10. The limiting structure 8 is connected to the first support plate 9. A limiting groove 14 is opened on one side of the top seat 2. The limiting structure 8 is clamped in the limiting groove 14. The clamping structure 7 includes a fixed column 701, a ferrule 702 and a fixed disk 704. An arc-shaped clamping plate 703 is fixedly connected to the outer surface of the ferrule 702. A coil spring 705 is sleeved outside the fixed column 701. The arc-shaped clamping plate 703 is clamped inside the installation column 11.

[0021] As Figure 1 and Figure 3 shown, the bearing ring 4 is clamped inside the top seat 2. The top seat 2 is connected to the base 1 through the bolt 3. The first support plate 9 and the second support plate 10 overlap. The fixed column 701 is fixedly connected to one side of the first support plate 9. The installation column 11 is clamped inside the first support plate 9. The fixed disk 704 is fixedly connected to one end of the fixed column 701. The ferrule 702 is rotatably connected outside the fixed column 701. The ferrule 702 is connected to the fixed disk 704 through the coil spring 705.

[0022] By setting the coil spring 705, when a rotational force is applied to the ferrule 702, the ferrule 702 will rotate on the surface of the fixed post 701. When the ferrule 702 rotates, it will drive the coil spring 705 to deform through the fixed disk 704, so that the coil spring 705 plays a certain supporting role in the rotation of the ferrule 702. When the resistance on the ferrule 702 is lost, it will be reset through the coil spring 705.

[0023] As Figure 4 shown, a delivery pipe 12 is fixedly connected above the top seat 2. A sealing cover 13 is clamped in the delivery pipe 12. The limiting structure 8 includes a positioning plate one 801 and a positioning plate two 802. The positioning plate one 801 is fixedly connected to the outer surface of the support plate two 10, and the positioning plate two 802 is fixedly connected to the outer surface of the support plate one 9. The positioning plate two 802 is clamped in the limiting groove 14, and the positioning plate one 801 is clamped in the limiting groove 14.

[0024] By setting the delivery pipe 12 and the sealing cover 13, when the bearing seat needs to be lubricated for the inner bearing ring 4 after use, the sealing cover 13 above the delivery pipe 12 can be taken out, and then the lubricating fluid can be injected into it through the delivery pipe 12, which can lubricate the surface of the bearing ring 4. And the sealing cover 13 can seal the top end of the delivery pipe 12 to prevent dust from entering the bearing seat through the delivery pipe 12.

[0025] The present utility model provides a bearing seat with strong sealing performance, and the specific working principle is as follows:

[0026] When the bearing seat is in use, the bearing ring 4 can be clamped into the base 1, and then the top seat 2 is lapped above the base 1. The top seat 2 is then connected to the base 1 through the bolt 3. After the base 1 and the top seat 2 are connected, the first protective ring 5 and the second protective ring 6 are sleeved on the left and right sides of the base 1. When the first protective ring 5 and the second protective ring 6 are sleeved, the support plate one 9 and the support plate two 10 on the surface will contact. The support plate one 9 will slide in the limiting groove 14 through the positioning plate two 802, and the support plate two 10 will slide in the limiting groove 14 through the positioning plate one 801. And the mounting post 11 on the left side of the support plate two 10 will penetrate through the support plate one 9. When the mounting post 11 penetrates through the support plate one 9, a rotational force is applied to the ferrule 702. When the ferrule 702 rotates on the surface of the fixed post 701, it will drive the coil spring 705 to deform. When the support plate one 9 and the support plate two 10 are in contact and the ferrule 702 is released, the ferrule 702 will be reset by the action of the coil spring 705, and the arc-shaped clamping plate 703 will be clamped in the mounting post 11 after the ferrule 702 is reset.

[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
