Description

Technical Field

[0001] This application relates to the field of spherical bearing housing technology, and in particular to a fully sealed spherical bearing housing. Background Technology

[0002] Normal spherical roller bearing assemblies are mostly used in agricultural machinery, mining machinery, conveyor belts, and other equipment. Since these bearings are in direct contact with the external environment, analysis of past bearing failures shows that most failures are due to the bearing's seals failing to prevent external contaminants from entering the bearing, causing severe wear on the internal steel balls and significantly reducing the bearing's lifespan. Additionally, some bearing housings have sealing structures, but these are typically steel plate skeletons with plastic end caps, resulting in poor rigidity and ineffective sealing. Utility Model Content

[0003] The purpose of this application is to provide a fully sealed outer spherical bearing housing to solve the technical problem of poor sealing performance in the original outer spherical bearing housing products.

[0004] To achieve the above objectives, this utility model provides a fully sealed spherical bearing housing, comprising a spherical bearing housing body, an spherical bearing, and a rotating shaft. One end of the rotating shaft is covered with a sealing end cap, which is detachably connected to the spherical bearing housing body. The other end of the rotating shaft passes through a through hole in the spherical bearing housing body and extends to the outside of the spherical bearing housing body. A radially extending annular sealing groove is formed in the through hole, and a sealing adhesive ring is filled in the annular sealing groove. The sealing adhesive ring is interference-fitted with the outer wall of the rotating shaft.

[0005] To facilitate the assembly and disassembly of the sealing end cap, the sealing end cap is a cylindrical hollow structure with one end being a closed end and the other end being an open end. The edge of the open end is detachably connected to the edge of the outer spherical bearing seat body by a locking screw.

[0006] To ensure the compactness of the overall structure of the bearing housing and reduce its overall length, one end of the outer spherical bearing and rotating shaft extends partially into the sealing end cover.

[0007] To further improve sealing performance, the sealing adhesive ring has a truncated conical structure, with the outer diameter of the circle containing its two end faces gradually decreasing from the center outwards.

[0008] The beneficial effects of this utility model are as follows: The fully sealed outer spherical bearing housing has a sealing groove machined at one end of the bearing housing, and a sealing felt ring is filled in the sealing groove. The felt ring is interference-fitted with the rotating shaft, which can play a good sealing role. The other end of the bearing housing is fully sealed through a sealing end cap. The product has good overall rigidity, is easy to transport and install, and is not easily damaged. Attached Figure Description

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0014] Combination Figure 1-4 The diagram shows a fully sealed spherical bearing housing, comprising a spherical bearing housing body 1, a spherical bearing 5, and a rotating shaft 6. The spherical bearing housing body 1 has an assembly port 7 for installing the spherical bearing 5. One end (right end) of the rotating shaft 6 is covered by a sealing end cap 2. The sealing end cap 2 is a cylindrical hollow structure made of gray cast iron, with one end (right end) being a closed end and the other end (left end) being an open end. The edge of the open end is detachably connected to the edge of the spherical bearing housing body 1 by several locking screws 3. The spherical bearing 5 and one end (right end) of the rotating shaft 6 partially extend to the sealing end. Inside the end cap 2, the other end of the rotating shaft 6 passes through the through hole in the left end of the outer spherical bearing housing body 1 and extends to the outside of the outer spherical bearing housing body 1. A radially extending annular sealing groove 8 is provided in the through hole. The annular sealing groove 8 is filled with a sealing felt ring 4. The sealing felt ring 4 has a truncated cone structure, and the outer diameter of the circle containing the left and right end faces gradually decreases from the center outward. The inner wall of the sealing felt ring 4 is interference-fitted with the outer wall of the rotating shaft 6. The sealing felt ring 4 is made of blended felt, pure wool felt, chemical fiber felt, and imported Australian wool felt, etc. The sealing felt ring 4 has good sealing performance, corrosion resistance and temperature resistance.

[0015] During installation, first assemble the sealing adhesive ring 4 into the sealing groove 8 of the outer spherical bearing housing body 1; then assemble the outer spherical bearing 5 into the outer spherical bearing housing body 1; next, install the rotating shaft 6 into the outer spherical bearing 5 through the sealing adhesive ring 4, and lock the rotating shaft 6 with the locking bolts on the outer spherical bearing 5; finally, assemble the sealing end cover 2 onto the outer spherical bearing housing body 1 with the locking screws 3, so that the entire product is in a completely sealed state, which enables the product to play a good sealing role and greatly improves the service life of the bearing product.

[0016] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
