Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled bearing seat seals, in particular to a sustainable seal for a water-cooled bearing seat. Background Art

[0002] With the continuous development of industrial technology, water-cooled bearing seats have been widely used in many high-temperature, high-speed, and heavy-load applications. Water-cooled bearing seats provide continuous cooling for bearings through the circulation of cooling medium (usually water), thereby improving the working efficiency and life of the bearings. However, after long-term operation, the sealing rings of existing water-cooled bearing seats will deteriorate in sealing performance due to corrosion, wear, or aging of the cooling medium. Once the sealing ring is damaged, it needs to be replaced with a new one.

[0003] Since the water-cooled bearing seat is usually directly connected to the body, the bearing seat and the body assembly must be disassembled when replacing the sealing ring. This fixed structure makes the disassembly and assembly process complicated, and various mechanical components need to be disassembled and re-oriented for docking. During the disassembly and assembly process, other components may be damaged. In particular, alignment is difficult during re-docking, which can easily cause dimensional deviation or damage. Frequent disassembly and assembly and maintenance work not only increases maintenance costs, but may also cause production interruptions and affect production efficiency. Therefore, a sustainable seal for water-cooled bearing seats is needed to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a sustainable seal for a water-cooled bearing seat, so as to solve the problem of inconvenience in replacing the sealing ring of the water-cooled bearing seat mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sustainable seal for a water-cooled bearing seat, comprising:

[0006] The bearing seat body is the main sealing body of the seal. A sealing groove is opened inside the bearing seat body for docking the seal. The seal includes a sealing disk, a conical protrusion and a sealing felt strip. The sealing felt strip is strip-shaped and wrapped inside the sealing groove. The conical protrusion is arranged on the inner edge of the sealing disk and is movably connected to the sealing felt strip. The sealing disk and the bearing seat body are threadedly connected.

[0007] As a preferred technical solution of the present invention, the sealing felt strip is axially deformed when being screwed into the conical protrusion.

[0008] As a preferred technical solution of the present invention, the thickness of the sealing felt strip is greater than the horizontal gap between the sealing discs.

[0009] As a preferred technical solution of the present invention, a plurality of limiting grooves are distributed in an annular manner on the outer surface of one end of the sealing disk, and one end of the limiting groove is in a semicircular structure.

[0010] As a preferred technical solution of the present invention, an outer surface of one end of the bearing seat body is rotatably connected to an elastic limiting rod, and a limiting block is provided on the bottom surface of the elastic limiting rod.

[0011] As a preferred technical solution of the present invention, the limiting block is embedded and connected with the limiting groove.

[0012] Compared with the prior art, the sustainable seal for the water-cooled bearing seat of the utility model has the following beneficial effects:

[0013] The seals can be replaced without disassembling the bearing seat and the body assembly, which simplifies the maintenance process, reduces the difficulty and risk of disassembly and assembly, reduces maintenance time and labor costs, and avoids the increased maintenance costs caused by damage to other components during the disassembly and assembly process. The winding design of the sealing felt strip allows it to re-seal by tightening the sealing disc after wear, thereby extending the service life of the seal. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-3 The utility model provides a technical solution: a sustainable seal for a water-cooled bearing seat, comprising:

[0019] The bearing seat body 1 is the main sealing body of the seal. A sealing groove 2 is opened inside the bearing seat body 1 for docking the seal. The seal includes a sealing disk 3, a conical protrusion 5 and a sealing felt strip 6. The sealing felt strip 6 is strip-shaped and wound inside the sealing groove 2. The conical protrusion 5 is arranged on the inner edge of the sealing disk 3 and is movably connected to the sealing felt strip 6. The sealing disk 3 is threadedly connected to the bearing seat body 1.

[0020] The sealing felt strip 6 is axially deformed when it is screwed into the conical protrusion 5, and the sealing felt strip 6 is filled between the bearing seat body 1 and the sealing disk 3. Since the conical protrusion 5 and the sealing disk 3 are an integrated structure, when the sealing disk 3 and the bearing seat body 1 are threaded, not only the horizontal gap between the bearing seat body 1 and the sealing disk 3 is shortened, but also the conical protrusion 5.

[0021] The thickness of the sealing felt strip 6 is greater than the horizontal gap between the sealing disc 3 and the sealing disc 3. The sealing felt strip 6 is filled in the sealing groove 2 after removing its own thickness, and there is still a movable gap between the bearing seat body 1 and the sealing groove 2 after the sealing felt strip 6 forms a sealing structure. When one end of the sealing felt strip 6 is more worn, the sealing felt strip 6 can be squeezed by tightening the sealing disc 3 to re-form the seal until the sealing felt strip 6 is consumed to the point where the sealing groove 2 and the sealing disc 3 are fitted together, and there is a gap between the sealing disc 3 and the sealing felt strip 6.

[0022] There are several limiting grooves 7 distributed in an annular manner on the outer surface of one end of the sealing disk 3. One end of the limiting groove 7 is a semicircular structure. Multiple limiting grooves 7 are set on the outer surface of the sealing disk 3. The shape of the limiting groove 7 corresponds to the shape of the limiting block 8, which facilitates the mutual docking of the limiting block 8 and the limiting groove 7, thereby playing the role of axial limiting the sealing disk 3.

[0023] The outer surface of one end of the bearing seat body 1 is rotatably connected to an elastic limiting rod 4, and a limiting block 8 is set on the bottom surface of the elastic limiting rod 4. One end of the elastic limiting rod 4 can be axially rotated along the surface of the bearing seat body 1. When the limiting block 8 of the elastic limiting rod 4 corresponds to the position of the limiting groove 7, the elastic limiting rod 4 is clamped into the inside of the limiting groove 7 to form a limit due to the elastic characteristics of the elastic limiting rod 4.

[0024] As a preferred technical solution of the present invention, the limiting block 8 is embedded and connected with the limiting groove 7.

[0025] Working principle: The preset length of the sealing felt strip 6 is slightly larger than the inner edge length of the sealing groove 2. The sealing felt strip 6 is inserted into the sealing groove 2 in a circular shape, and then the sealing disk 3 is screwed in and the conical protrusion 5 is inserted into the sealing felt strip 6. After the sealing disk 3 is tightened, a sealing structure with the bearing seat body 1 is formed. One end of the elastic limiting rod 4 can rotate axially along the surface of the bearing seat body 1. When the limit block 8 of the elastic limiting rod 4 corresponds to the position of the limit groove 7, the elastic limit rod 4 is inserted into the limit groove 7 through the elastic characteristics of the elastic limiting rod 4. The limit groove 7 is limited. When there is a gap between the sealing felt strip 6 and the sealing groove 2, the limit groove 7 is separated from the limit block 8, the sealing disk 3 is tightened and the sealing felt strip 6 is continued to be squeezed until the sealing felt strip 6 fits together with the sealing disk 3 and the sealing groove 2 again. The maintenance and replacement of the sealing structure can be completed without disassembling the bearing seat assembly.
