Description

Technical Field

[0001] This utility model relates to the field of diaphragm coupling technology, specifically a long-axis diaphragm coupling for horizontal units. Background Technology

[0002] Diaphragm couplings can be divided into single diaphragm and double diaphragm plus intermediate section combination. Single diaphragm is suitable for units with shorter shaft spacing and no intermediate section is required, while double diaphragm is suitable for units with slightly longer shaft spacing.

[0003] For units with particularly long shaft spacing, the intermediate section of the coupling is lengthened according to the length of the unit. This increased weight, typically made of metal, places a significant load on the diaphragm assemblies on both sides. While carbon fiber could effectively address this issue, it is very expensive. Using a metal intermediate section would be much cheaper. The challenge has been finding a way to replace carbon fiber intermediate sections with metal ones in horizontal units, while simultaneously reducing the load on the diaphragm assemblies due to the metal section's weight.

[0004] To address the aforementioned issues, we propose a long-axis diaphragm coupling for horizontal units. Utility Model Content

[0005] The purpose of this invention is to provide a long-axis diaphragm coupling for horizontal units to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-axis diaphragm coupling for horizontal units, comprising a diaphragm assembly, a drive bolt, a bearing mounting base, a rolling bearing, and a bearing fixing bolt.

[0007] The diaphragm assembly is disposed between the half-shaft joint and the intermediate section; the diaphragm assembly is connected between the half-shaft joint and the intermediate section by the drive bolt; the bearing mounting seat is sleeved on the outer circumferential wall of the connection between the half-shaft joint and the intermediate section; the rolling bearing is provided inside the bearing mounting seat; the rolling bearing is connected to the bearing mounting seat by the bearing fixing bolt; the outer circumferential wall of the rolling bearing abuts against the outer circumferential wall of the flange end of the intermediate section.

[0008] Preferably, a T-shaped bearing limiting block is provided on each of the two ends of the rolling bearing; the T-shaped bearing limiting block is sleeved on the bearing fixing bolt.

[0009] Preferably, a bearing adjusting block is also fitted onto the bearing fixing bolt; one end face of the bearing adjusting block abuts against the inner side wall of the bearing fixing seat; the other end face of the bearing adjusting block abuts against the end face of one of the T-shaped bearing limiting blocks.

[0010] Preferably, the T-shaped bearing limiting block adopts a T-shaped structure.

[0011] Preferably, a plurality of rolling bearings are evenly arranged along the circumferential direction inside the bearing mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a metal intermediate section instead of a carbon fiber intermediate section, and utilizes rolling bearings to radially restrict the intermediate section, thereby reducing its weight, increasing the service life of the diaphragm assembly, and preventing the intermediate section from flying off in case of component damage. This achieves the goals of reducing costs, increasing lifespan, and shortening the processing cycle. Attached Figure Description

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a long-axis diaphragm coupling for horizontal units, including a diaphragm assembly 1, a drive bolt 2, a bearing mounting seat 3, a rolling bearing 4, and a bearing fixing bolt 5.

[0017] The diaphragm assembly 1 is disposed between the half-shaft joint 6 and the intermediate section 7. The diaphragm assembly 1 is connected between the half-shaft joint 6 and the intermediate section 7 by the drive bolt 2. The bearing fixing seat 3 is sleeved on the outer circumferential wall of the connection between the half-shaft joint 6 and the intermediate section 7. The rolling bearing 4 is provided inside the bearing fixing seat 3. The rolling bearing 4 is connected to the bearing fixing seat 3 by the bearing fixing bolt 5. The outer circumferential wall of the rolling bearing 4 abuts against the outer circumferential wall of the flange end of the intermediate section 7.

[0018] In this invention, multiple rolling bearings 4 are radially distributed along the outer circumference of the intermediate section 7. This allows the rolling bearings 4 to limit the sagging of the intermediate section 7 due to its own weight, distributing the weight of the intermediate section to the components at both ends. Thus, under static or dynamic loads, the diaphragm assembly 1 is not subjected to circumferential force from the intermediate section 7, thereby improving the lifespan of the diaphragm assembly 1 and the overall lifespan of the coupling of this invention. Furthermore, the cost of the intermediate section 7 is relatively low. During torsion, the rolling bearings 4 can also provide radial compensation to the intermediate section 7, limiting the risk of it flying off, but without limiting its axial compensation.

[0019] Furthermore, a T-shaped bearing limiting block 8 is provided on each of the two end faces of the rolling bearing 4, and the T-shaped bearing limiting block 8 is sleeved on the bearing fixing bolt 5.

[0020] Furthermore, a bearing adjusting block 9 is also fitted on the bearing fixing bolt 5. One end face of the bearing adjusting block 9 abuts against the inner side wall of the bearing fixing seat 3, and the other end face of the bearing adjusting block 9 abuts against the end face of one of the T-shaped bearing limiting blocks 8.

[0021] Furthermore, the T-shaped bearing limiting block 8 adopts a T-shaped structure.

[0022] Furthermore, a plurality of rolling bearings 4 are evenly arranged in the bearing mounting base 3 along the circumferential direction.

[0023] The bearing mounting base 3 is tightened onto the flange of the half-shaft joint 6 by the drive bolt 2. The bearing adjusting block 9 adjusts the axial position of the rolling bearing 4, confining the rolling bearing 4 at the outer circumference of the middle section. The T-shaped bearing limiting block 8 restricts the axial movement of the inner and outer rings of the rolling bearing 4. The bearing fixing bolt 5 fixes the parts and the rolling bearing 4 onto the bearing mounting base 3. This utility model exhibits low vibration, safety and reliability during operation, and long service life, achieving standards of safety, high efficiency, low cost, and long service life.

[0024] This invention uses a metal intermediate section 7 instead of a carbon fiber intermediate section, and utilizes the rolling bearing 4 to radially restrict the intermediate section 7, thereby reducing its weight, increasing the service life of the diaphragm assembly 1, and preventing the intermediate section from flying off after component damage. This achieves the goals of reducing costs, increasing lifespan, and shortening the processing cycle.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
