Description

Technical Field

[0001] This utility model belongs to the field of coupling technology, specifically a single-sided four-diaphragm disc coupling. Background Technology

[0002] Grinding disc couplings are high-performance flexible couplings that compensate for axial, radial, and angular misalignments through elastic deformation. Due to their high precision, high rigidity, and maintenance-free characteristics, they are widely used in high-speed, high-precision, and large-compensation transmission systems. With the increasing demand for intelligent, lightweight, and ultra-high-speed transmissions, grinding disc coupling technology will continue to upgrade and replace traditional couplings in more fields.

[0003] Single-diaphragm couplings and double-diaphragm couplings are now widely used in various fields. However, the requirements for axial, radial, and angular deviations are becoming increasingly stringent. Existing double-diaphragm couplings have limited compensation capabilities, and couplings with greater compensation capabilities are needed to meet market application demands. Therefore, we propose a single-sided four-diaphragm coupling. Utility Model Content

[0004] To address the problems raised in the background art, this utility model provides the following technical solution: a single-sided four-diaphragm disc coupling, comprising a driving end connecting flange, a driven end connecting flange, four diaphragms, and a deformation limiting device. The four diaphragms are sequentially welded together, and both ends of the four diaphragms are respectively connected to the driving end connecting flange and the driven end connecting flange. The deformation limiting device is connected to the two middle diaphragms among the four diaphragms, and the deformation limiting device is used to limit the deformation of the diaphragms.

[0005] Preferably, the total axial deformation of the four diaphragm discs is 20mm, and the deformation of each diaphragm disc is 5mm. The deformation limiting device can be designed with a deformation space based on the 5mm deformation of each diaphragm disc. The limiting device allows the diaphragm disc to deform freely within a range of 5mm, but it will be restricted if it exceeds this range, thereby ensuring the rigidity and stability of the coupling.

[0006] Preferably, the diaphragm is made of thin-plate ultra-strong alloy steel or titanium alloy, which has high strength, lightweight and good elastic deformation capacity, and can meet the application requirements of couplings in high speed, high precision and large compensation.

[0007] Preferably, the two single-sided four-diaphragm disc couplings are connected by an intermediate section, which is used to connect the driven end connecting flange and the driving end connecting flange of the two single-sided four-diaphragm disc couplings to form a complete coupling. The complete coupling contains a total of eight diaphragm discs, which can provide greater compensation capacity and higher torque transmission capacity, and is suitable for transmission systems with higher requirements for compensation and torque.

[0008] Preferably, the intermediate section is connected to the driven end connecting flange and the driving end connecting flange by a fastener assembly, ensuring a firm connection between the intermediate section and the flange, thereby guaranteeing the structural stability of the entire coupling.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] During operation, four diaphragm discs are welded together sequentially to form a single-sided four-diaphragm disc structure. Then, one end of each single-sided four-diaphragm disc is connected to the active end connecting flange, and the other end is connected to the driven end connecting flange. Finally, deformation limiting devices are installed on the two middle discs. If greater compensation and torque transmission capabilities are required, two single-sided four-diaphragm disc couplings can be connected through an intermediate section to form a double-sided eight-diaphragm disc coupling. The intermediate section is connected to the driven end connecting flange and the active end connecting flange through a fastener assembly. When the drive unit starts, the active end connecting flange begins to rotate and transmits torque to the four diaphragm discs. While transmitting torque, the diaphragm discs undergo elastic deformation according to the magnitude of axial, radial, and angular deviations. The deformation limiting device monitors the deformation of the diaphragm discs in real time and limits deformation when necessary to ensure stable operation of the coupling. The torque transmitted through the diaphragm discs finally reaches the driven end connecting flange, thereby driving the driven equipment to operate normally. It can transmit high torque while having large axial, radial, and angular compensation capabilities. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figure 1-2The present invention includes an active end connecting flange 1, a driven end connecting flange 2, four diaphragm discs 3 and a deformation limiting device 4. The four diaphragm discs 3 are welded together in sequence, and the two ends of the four diaphragm discs 3 are respectively connected to the active end connecting flange 1 and the driven end connecting flange 2. The deformation limiting device 4 is connected to the middle two of the four diaphragm discs 3 and is used to limit the deformation of the diaphragm discs 3.

[0017] The total axial deformation of the four diaphragm discs 3 is 20mm, and the deformation of each diaphragm disc 3 is 5mm. The deformation limiting device 4 can be designed with a deformation space based on the 35mm deformation of each diaphragm disc. The limiting device allows the diaphragm disc to deform freely within a range of 5mm, but it will be restricted if it exceeds this range, thereby ensuring the rigidity and stability of the coupling.

[0018] The diaphragm plate 3 is made of thin-plate ultra-strong alloy steel or titanium alloy, which has high strength, lightweight and good elastic deformation capacity, and can meet the application requirements of couplings in high speed, high precision and large compensation.

[0019] Two single-sided four-diaphragm disc couplings are connected by an intermediate section. The intermediate section is used to connect the driven end connecting flange 2 and the driving end connecting flange 1 of the two single-sided four-diaphragm disc couplings to form a complete coupling. The complete coupling contains a total of eight diaphragm discs 3, which can provide greater compensation capacity and higher torque transmission capacity, and is suitable for transmission systems with higher requirements for compensation and torque.

[0020] The intermediate section is connected to the driven end connecting flange 2 and the driving end connecting flange 1 through a fastener assembly, ensuring a firm connection between the intermediate section and the flanges, thereby guaranteeing the structural stability of the entire coupling.

[0021] Working principle: During operation, four diaphragm discs 3 are welded together in sequence to form a single-sided four-diaphragm disc structure. Then, one end of the single-sided four-diaphragm disc is connected to the active end connecting flange 1, and the other end is connected to the driven end connecting flange 2. Finally, the deformation limiting device 4 is installed on the two middle discs of the diaphragm discs. If greater compensation and torque transmission capabilities are required, two single-sided four-diaphragm disc couplings can be connected through an intermediate section to form a double-sided eight-diaphragm disc coupling. The intermediate section is connected to the driven end connecting flange 2 and the active end connecting flange 1 through a fastener assembly. When the drive device, such as a motor, starts, the active end connecting flange 1 begins to rotate and transmits torque to the four diaphragm discs 3. While transmitting torque, the diaphragm discs undergo elastic deformation according to the magnitude of axial, radial, and angular deviations. The deformation limiting device 4 monitors the deformation of the diaphragm discs in real time and limits the deformation when necessary to ensure the stable operation of the coupling. The torque transmitted through the diaphragm discs finally reaches the driven end connecting flange 2, thereby driving the driven equipment, such as pumps and fans, to operate normally. It can transmit high torque while having large axial, radial, and angular compensation capabilities.
