Description

Technical Field

[0001] This utility model belongs to the technical field of diaphragm couplings, and particularly relates to a separation clamping type diaphragm coupling. Background Technology

[0002] Currently, the commonly known diaphragm coupling consists of left and right bushings, a middle spacer, two sets of laminated plate assemblies, bolts, and nuts. The laminated plate assemblies are composed of several thin stainless steel sheets, allowing for a certain degree of deformation and compensating for larger axial and radial deviations. However, due to the large interference fit between the left and right bushings and the connecting shaft in some large-sized diaphragm couplings, installation and disassembly are difficult, causing significant inconvenience to equipment maintenance.

[0003] Therefore, it is necessary to provide a new type of diaphragm coupling with a separation clamping mechanism to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a diaphragm coupling that can not only solve the problem of difficult installation and disassembly of the left and right bushings and connecting shaft, but also ensure sufficient interference fit.

[0005] To solve the above-mentioned technical problems, the diaphragm coupling with separation clamping provided by this utility model includes: a left half coupling and a right half coupling;

[0006] The left half coupling includes several parts: a split bushing, a hexagonal head reamed bolt, a laminated assembly, a self-locking nut, and a split bushing.

[0007] The right half coupling includes several parts: a hexagonal head reamed bolt, a laminated plate assembly, a self-locking nut, a split right bushing, and a split bushing.

[0008] As a further embodiment of this utility model, an intermediate sleeve is provided between the split bushing one and the split right bushing three. The intermediate sleeve is connected to the lamination assembly one on the split bushing one and the lamination assembly two on the split right bushing three respectively through hexagonal head reamer bolt one and hexagonal head reamer bolt two.

[0009] As a further embodiment of this utility model, the self-locking nut is installed on the intermediate sleeve, one end of the hexagonal head reamed hole bolt passes through the split bushing, the stacked plate assembly and the self-locking nut, the hexagonal head reamed hole bolt is adapted to the split bushing and the stacked plate assembly, and the hexagonal head reamed hole bolt is screwed into the self-locking nut.

[0010] As a further embodiment of this utility model, the second self-locking nut is installed on the split right bushing three, one end of the second hexagonal head reamed hole bolt passes through the intermediate sleeve, the second stacked plate assembly and the second self-locking nut, the second hexagonal head reamed hole bolt is adapted to the intermediate sleeve and the second stacked plate assembly, and the second hexagonal head reamed hole bolt is screwed into the second self-locking nut.

[0011] As a further embodiment of this utility model, the split bushing one and split bushing two are connected to the equipment by internal hex bolts.

[0012] As a further embodiment of this utility model, the split right bushing three and split bushing four are connected to the equipment by internal hex bolts.

[0013] Compared with related technologies, the diaphragm coupling with separation clamping provided by this utility model has the following beneficial effects:

[0014] 1. This utility model transforms the interference fit of the traditional integral bushing into an adjustable bolt clamping force fit by using a split bushing and an internal hex bolt. This avoids forced assembly by external force when installing and disassembling large couplings, significantly reducing the difficulty of operation and shortening maintenance time.

[0015] 2. The split bushing of this utility model ensures the interference fit with the connecting shaft through the bolt preload. The preload can be adjusted according to the usage requirements to avoid loosening caused by interference fit decay during long-term use, thereby improving the stability and reliability of the coupling operation.

[0016] 3. This utility model, based on a modular split structure, allows for the individual replacement of damaged components (such as laminated assemblies or bushings) without the need for complete disassembly of the coupling, thereby reducing maintenance costs and downtime and improving equipment utilization.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the external structure of this utility model; Figure 3 for Figure 2 A cross-sectional view. The split-clamp type diaphragm coupling includes: a left half-coupling and a right half-coupling;

[0023] The left half coupling includes several parts: a split bushing (1), a hexagonal head reamed bolt (2), a laminated assembly (3), a self-locking nut (4), and a split bushing (11);

[0024] The right half coupling includes a hexagonal head reamed bolt (6), a laminated assembly (7), a self-locking nut (8), a split right bushing (9), and a split bushing (10).

[0025] An intermediate sleeve (5) is provided between the split bushing one (1) and the split right bushing three (9). The intermediate sleeve (5) is connected to the lamination assembly one (3) on the split bushing one (1) and the lamination assembly two (7) on the split right bushing three (9) by hexagonal head reamer bolt one (2) and hexagonal head reamer bolt two (6), respectively.

[0026] The self-locking nut (4) is installed on the intermediate sleeve (5). One end of the hexagonal head reamed hole bolt (2) passes through the split bushing (1), the laminated assembly (3), and the self-locking nut (4). The hexagonal head reamed hole bolt (2) is adapted to the split bushing (1) and the laminated assembly (3). The hexagonal head reamed hole bolt (2) is screwed into the self-locking nut (4).

[0027] The self-locking nut 2 (8) is installed on the split right bushing 3 (9). One end of the hexagonal head reamed hole bolt 2 (6) passes through the intermediate sleeve (5), the stacked plate assembly 2 (7) and the self-locking nut 2 (8). The hexagonal head reamed hole bolt 2 (6) is adapted to the intermediate sleeve (5) and the stacked plate assembly 2 (7). The hexagonal head reamed hole bolt 2 (6) is screwed into the self-locking nut 2 (8).

[0028] The split bushing one (1) and split bushing two (11) are connected to the equipment by internal hex bolts (12).

[0029] The split right bushing three (9) and split bushing four (10) are connected to the equipment by internal hex bolts (12).

[0030] The working principle of the diaphragm coupling with separation and clamping provided by this utility model is as follows:

[0031] First step: The left and right bushings of the separation clamping diaphragm coupling are both of a split structure (such as split bushing one (1) and split bushing two (11) of the left half coupling, and split right bushing three (9) and split bushing four (10) of the right half coupling). Each split bushing is connected by an internal hex bolt (12). During installation, first put the split bushing on the connecting shaft of the equipment to ensure that the bushing and the shaft are aligned. Then tighten the internal hex bolt (12). The clamping force of the bolt makes the inner wall of the split bushing form an interference fit with the connecting shaft, thereby fixing the bushing.

[0032] Second step: The intermediate sleeve (5) is connected to the lamination assembly 1 (3) of the left half coupling and the lamination assembly 2 (7) of the right half coupling through hexagonal head reamer bolt 1 (2) and hexagonal head reamer bolt 2 (6) respectively. After the bolts pass through the bushing and the lamination assembly, they are screwed into the self-locking nut 1 (4) and self-locking nut 2 (8) to form a rigid connection, ensuring that the power is reliably transmitted through the elastic deformation of the lamination assembly;

[0033] Third step: During disassembly, simply loosen the internal hex bolt (12), and the split bushing can be separated along the split surface, releasing the clamping force on the connecting shaft. No additional tools or external force are required, greatly simplifying the disassembly process.
