Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a bearing flange. Background Technology

[0002] Bearing flanges are key mechanical components that integrate sealing, lubrication, and dynamic compensation functions. They are specifically designed for rotating shaft systems and are suitable for harsh operating conditions such as construction machinery, wind power equipment, and heavy-duty transmissions. Their core structure includes a flange cover, rotating shaft, bearing, and innovative sealing components, achieving high reliability and long service life through multi-dimensional collaborative design.

[0003] The oil seals on existing bearing flanges are prone to coming off under violent rotation of the shaft, and are not securely fixed, which will seriously affect the reliability of the machine tool.

[0004] Based on this, the present invention designs a bearing flange to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bearing flange to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing flange, including a flange cover, a rotating shaft passing through the center of the flange cover, a bearing installed between the flange cover and the rotating shaft, a bearing cover fitted onto the left side of the flange cover and inserted into the left end of the rotating shaft, an oil seal on the right side of the flange cover, and lubricant filling the inner cavity of the flange cover; an annular groove is formed on the right side of the inner cavity of the flange cover, and openings communicating with the annular groove are evenly formed on the right side wall of the flange cover; the oil seal includes an oil seal body, and fins equal in number to the openings are fixed to the side wall of the oil seal body; the fins can pass through the openings, and by rotating the oil seal body, the fins can be rotated into the closed annular groove.

[0007] Preferably, the oil seal body is a skeleton oil seal with a C-shaped cross-section.

[0008] Preferably, the outer surface of the oil seal is provided with anti-slip texture.

[0009] Preferably, the bearing cover and the flange cover are fixedly connected by screws.

[0010] Preferably, the fins are trapezoidal.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this utility model forms axial constraint through the interlocking structure of fins and openings, enhances circumferential friction through anti-slip texture, generates radial clamping force through C-shaped skeleton, and constructs a three-dimensional constraint system, which improves the oil seal's anti-displacement capability by more than 60%; the elastic deformation capability of the C-shaped oil seal body can compensate for axial clearance changes of 0.2-0.5mm.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a bearing flange technical solution: a bearing flange includes a flange cover 1, a rotating shaft 2 is disposed through the center of the flange cover 1, a bearing 3 is installed between the flange cover 1 and the rotating shaft 2, a bearing cover 4 is fixedly disposed on the left side of the flange cover 1 and fits into the left end of the rotating shaft 2, an oil seal 5 is disposed on the right side of the flange cover 1, and the inner cavity of the flange cover 1 is filled with lubricant; an annular groove 111 is opened on the right side of the inner cavity of the flange cover 1, and openings 112 communicating with the annular groove 111 are evenly opened on the right side wall of the flange cover 1, the oil seal 5 includes an oil seal body 51, and fins 52 of the same number as the openings 112 are fixedly disposed on the side wall of the oil seal body 51, and the fins 52 can pass through the openings 112.

[0022] Furthermore, the oil seal body 51 is a skeleton oil seal with a C-shaped cross-section.

[0023] Furthermore, the outer surface of the oil seal 5 is provided with anti-slip texture. The anti-slip texture enhances circumferential friction, making it convenient for manual rotation and unloading while also preventing it from rotating due to working vibrations after installation.

[0024] Furthermore, the bearing cover 4 and the flange cover 1 are fixedly connected by screws, which facilitates disassembly and assembly while ensuring a more secure fixation.

[0025] Furthermore, the fin 52 is trapezoidal, which increases the contact area with the annular groove 111 and makes it less prone to displacement.

[0026] This invention forms axial constraint through the interlocking structure of fins and openings, enhances circumferential friction through anti-slip texture, and generates radial clamping force through the C-shaped skeleton, thus constructing a three-dimensional constraint system that improves the oil seal's resistance to displacement by more than 60%. The elastic deformation capability of the C-shaped oil seal body can compensate for axial clearance changes of 0.2-0.5mm.
