Description

Technical Field

[0001] This utility model belongs to the technical field of diaphragm disc couplings, and in particular relates to a diaphragm disc coupling with flexible laminated plates. Background Technology

[0002] Some mechanical equipment consists of a motor and a shaft. When the motor is powered on, it drives the shaft to rotate, thus driving the mechanical equipment to operate. To prevent the motor and shaft from disengaging, changing their rotation direction, or changing their torque, a coupling is used to connect the motor and the shaft. There are many types of couplings, including cross couplings, clamp couplings, universal couplings, and diaphragm couplings.

[0003] A search revealed a diaphragm coupling structure in patent publication number CN215980530U, comprising an input diaphragm group, an intermediate body, an output diaphragm group, and a flange. The input and output diaphragm groups are fixedly connected to the intermediate body, which is located between them. The flange is fixedly connected to the input diaphragm group. Its innovation lies in the inclusion of an output locking mechanism, which is fixedly connected to the output diaphragm group. The output locking mechanism includes a locking outer ring and an inner tapered sleeve. The locking outer ring is fitted around the outer circumference of the inner tapered sleeve, which is fixedly connected to the output diaphragm group. This eliminates the need for a keyed connection or interference fit with the equipment spindle, simplifying installation and reducing operating costs.

[0004] However, diaphragm couplings still have the following drawbacks in practical use: 1. There are symmetrically fitted forward discs on the circumferential sidewalls of the connecting shaft. The two ends of the connecting shaft are provided with driving and driven shaft sleeves. Reverse discs are symmetrically fixed on the circumferential sidewalls of the driving and driven shaft sleeves. Through holes are arranged in a ring array on the sidewalls of both the forward and reverse discs. Bolts pass through the through holes. Nuts with threaded connections are on the circumferential sidewalls of the bolts, which are used to lock the forward and reverse discs. However, multiple sets of bolts and nuts are independent individuals. Multiple sets of bolts and nuts need to be tightened to achieve the disassembly and assembly of the forward and reverse discs. Moreover, the number of independent individuals is large, which may cause the loss of bolts or nuts, and cannot guarantee the disassembly and assembly of the forward and reverse discs. 2. A diaphragm is provided between the reverse and forward discs to achieve angular and axial compensation. However, although the diaphragm can compensate for deviations, the range is small (usually less than one degree in the angular direction), which can cause cracks at the bolt hole edges and has limited load-bearing capacity.

[0005] To address these issues, we provide a diaphragm disc coupling with flexible laminations. Utility Model Content

[0006] The purpose of this invention is to provide a diaphragm disc coupling with flexible laminates. By setting up connecting components, the number of independent components is reduced, the loss of positioning rods is avoided, and the normal assembly and disassembly of the forward and reverse discs are ensured. Furthermore, by setting up flexible components, the flexible laminates are made of multiple layers of stacked metal sheets, resulting in higher structural rigidity, the ability to withstand greater torque and impact loads, greater flexibility in angular and axial compensation, and better adaptability to high temperatures and harsh environments. The root of the flexible laminates is optimized (e.g., with an arc transition) to reduce stress concentration and extend fatigue life, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a diaphragm disc coupling with flexible laminates, comprising a connecting shaft, a forward disc symmetrically sleeved on the peripheral sidewall of the connecting shaft, a reverse disc provided on the side of the forward disc, and a connecting assembly provided on the opposite surfaces of the forward and reverse discs.

A flexible assembly is provided between the forward and reverse discs, and the flexible assembly includes a ring array of through holes opened on the sidewall of the flexible laminate, through which the positioning rods pass.
