Description

Technical Field

[0001] The utility model belongs to the technical field of bearing equipment, and particularly relates to a stable bearing ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Bearing rings are annular parts of radial rolling bearings with one or more raceways. Bearing rings are annular parts of radial rolling bearings with one or more raceways.

[0003] Since bearings are used in harsh environments, especially in engineering machinery, road construction machinery, agricultural machinery, etc., strict dust and pollution prevention requirements are imposed on their sealing performance. However, in the existing technology, the sealing ring is generally connected between the inner ring and the outer ring and fixed between the inner ring and the outer ring using an interference fit. However, when used in an environment with large vibrations, the sealing ring is prone to fall off, reducing the stability of the bearing, causing foreign matter to enter the ring, and even causing the bearing to become stuck and fail. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art and provide a stable bearing ring. By arranging a mounting groove on the outer wall surface of the inner ring, the inner wall surface of the seal is clamped in the mounting groove. The arrangement of the mounting groove increases the contact area between the inner ring and the seal ring, thereby improving the stability of the installation of the seal ring. At the same time, a fixing piece is arranged on the outer side of the seal ring, which clamps the seal ring in the mounting groove, increases the connection strength between the seal ring and the inner ring, avoids the seal ring from falling off, and thus improves the stability of the bearing.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A stable bearing ring includes an outer ring, an inner ring, and a sealing ring. A raceway for mounting a rolling element is provided between the outer ring and the inner ring. The inner ring is provided with mounting grooves at both ends of the raceway. The inner wall surface of the sealing ring is clamped in the mounting groove, the inner wall surface of the sealing ring abuts in the mounting groove, and the outer wall surface of the sealing ring abuts against the inner wall surface of the outer ring. A fixing piece is provided on the outer side of the sealing ring, and the fixing piece clamps the sealing ring in the mounting groove. The utility model provides a mounting groove on the outer wall surface of the inner ring, so that the inner wall surface of the sealing piece is clamped in the mounting groove. The provision of the mounting groove increases the contact area between the inner ring and the sealing ring, thereby improving the stability of the sealing ring installation. At the same time, a fixing piece is provided on the outer side of the sealing ring, and the fixing piece clamps the sealing ring in the mounting groove, thereby increasing the connection strength between the sealing ring and the inner ring, preventing the sealing ring from falling off, and thus improving the stability of the bearing.

[0007] Furthermore, the outer wall of the inner ring is recessed inward to form a semi-arc groove 1, and the inner wall of the outer ring is correspondingly recessed to form a semi-arc groove 2. These two grooves together form a raceway. When the inner ring is positioned within the outer ring, these two grooves together form the raceway, which limits the position of the rolling element, ensuring its rolling motion within the raceway and improving its rolling stability.

[0008] Furthermore, the side of the mounting groove section closest to the rolling element is a flat surface, which is arranged parallel to the raceway, and the other side of the mounting groove section is a guiding slope. The flat surface improves the stability of the sealing ring placement, and the guiding slope facilitates the installation of the sealing ring.

[0009] Furthermore, the sealing ring includes a sealing portion and a clamping portion, wherein the sealing portion is provided at both ends of the raceway to seal the raceway, and the clamping portion is clamped in the mounting groove. The clamping portion is provided in the mounting groove, and the sealing portions at both ends seal the raceway.

A rotating block is provided at one end of the semicircular snap ring 1, and a rotating groove is provided at the corresponding end of the semicircular snap ring 2. The rotating block is rotatably connected in the rotating groove via a rotating shaft. The other end of the semicircular snap ring 1 is provided with a fixed block 1, and the other end of the semicircular snap ring 2 is correspondingly provided with a fixed block 2. A locking screw is inserted between the fixed block 1 and the fixed block 2, and locking nuts are screwed into both ends of the locking screw. The locking nuts are respectively tightened on the fixed block 1 and the fixed block 2. By enclosing the semicircular snap ring 1 and the semicircular snap ring 2, the sealing ring is clamped in the installation groove, and then fixed with the locking screw and locking nut, thereby increasing the connection strength between the sealing ring and the inner ring.

[0012] Furthermore, fixed block 1 has a stepped hole 1 extending through it, and fixed block 2 has a corresponding stepped hole 2 extending through it. The locking screw passes through stepped hole 1 and stepped hole 2, and the locking nut is tightened in stepped hole 1 and stepped hole 2, respectively. The provision of stepped hole 1 and stepped hole 2 prevents the locking nut and locking screw from protruding from the fixed block.

[0013] Furthermore, the outer wall of the semicircular snap ring 1 and the outer wall of the semicircular snap ring 2 are both circumferentially distributed with stiffening ribs, which abut against the sealing ring. The provision of the stiffening ribs increases the contact area between the fixing member and the sealing ring, thereby improving the stability of the sealing ring installation.

The flat surface improves the stability of the sealing ring placement, and the guide slope facilitates the installation of the sealing ring.

[0017] The fixing member in the utility model includes a semicircular snap ring 1 and a semicircular snap ring 2. A rotating block is provided at one end of the semicircular snap ring 1, and a rotating groove is provided at the corresponding end of the semicircular snap ring 2.

[0026] like Figures 1 to 6 As shown, a stable bearing ring of the present invention includes an outer ring 1, an inner ring 2 and a sealing ring 3. A raceway for mounting rolling elements 4 is provided between the outer ring 1 and the inner ring 2. Mounting grooves 5 are provided at both ends of the raceway of the inner ring 2. The inner wall surface of the sealing ring 3 is clamped in the mounting groove 5. The inner wall surface of the sealing ring 3 abuts against the mounting groove 5. The outer wall surface of the sealing ring 3 abuts against the inner wall surface of the outer ring 1. A fixing piece 6 is provided on the outer side of the sealing ring 3. The fixing piece 6 clamps the sealing ring 3 in the mounting groove 5.

[0027] The outer wall of the inner ring 2 is recessed inward to form a semi-arc groove 1 (7). The inner wall of the outer ring 1 is correspondingly recessed to form a semi-arc groove 2 (8). Together, these two grooves form a raceway. When the inner ring 2 is positioned within the outer ring 1, these two grooves form a raceway that limits the position of the rolling element 4, ensuring its rolling stability.

[0028] The side of the mounting groove 5 section close to the rolling surface is a flat surface 9, which is arranged parallel to the raceway, and the other side of the mounting groove 5 section is a guide slope 10. The setting of the flat surface 9 improves the stability of the placement of the sealing ring 3, and the setting of the guide slope 10 facilitates the installation of the sealing ring 3.

[0029] The sealing ring 3 includes a sealing portion 11 and a clamping portion 12.
