Description

Technical Field

[0001] This utility model relates to the technical field of flange couplings, specifically a small flange coupling. Background Technology

[0002] Flange couplings typically consist of two metal jaw discs and a flexible ring. The flexible ring is fixed to the jaw discs by a pin or other locking structure. The center of the two metal jaw discs has a mounting port for keying the drive shaft and driven shaft, respectively.

[0003] For example, the Chinese patent with publication number CN217539371U, entitled "(A Non-Extending Flange Coupling)," includes: two bushings, each with a rotating shaft coaxially connected to its opposite ends; and a first flange and a second flange fitted together at their opposite ends. Multiple matching bolts are inserted between the first and second flanges, evenly distributed in a ring. Each bolt has a threaded locking nut that abuts against the side wall of the second flange. A fixing block corresponding to the locking nut is fixedly installed on the side wall of the second flange. A pressure block is provided between the fixing block and the locking nut, fitting against the side wall of the locking nut. A positioning block is fixedly installed on the side of the pressure block closest to the locking nut. This application ensures that after the flange coupling is installed using bolts and nuts, the nuts are less likely to loosen, thus effectively improving installation stability.

[0004] However, the elastic element not only needs to be fixed axially between the connecting part and the two metal claw discs, but also needs to be connected between the elastic element and the iron core, which limits the radial buffering and shock absorption effect. Therefore, it does not meet the existing requirements. To address this, we propose a small flange coupling. Utility Model Content

[0005] The purpose of this utility model is to provide a small flange coupling to solve the problem mentioned in the background art that the elastic element in the existing flange coupling not only needs to be fixed between the connecting part and the two metal claw discs in the axial direction, but also needs to be connected between the elastic element and the iron core, which limits the radial buffering and shock absorption effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small flange coupling, comprising: a sealing plate, a cover provided on the outside of one side of the sealing plate, a nut provided on the other side of the sealing plate, the cover being threadedly connected to the sealing plate by an internal hexagonal head screw, one end of the internal hexagonal head screw extending to the nut for threaded fixation;

[0007] Also includes:

[0008] A nylon frisbee is installed inside the sealing plate and the cover. A ring of nylon petals is provided around the outer side of the nylon frisbee, and there are several nylon petals. The several nylon petals are integrally formed with the nylon frisbee. An elastic body is provided between the several nylon petals, and a connecting sleeve is provided at the middle position of the elastic body.

[0009] Preferably, an open cavity is provided at the middle position inside the nylon frisbee, a T-shaped cavity is provided at the middle position inside the open cavity, and an mounting iron core is provided inside the open cavity. The mounting iron core is configured such that the diameters at both ends are lower than the diameter at the middle position, forming a stepped shape that corresponds to the open cavity and the T-shaped cavity.

[0010] Preferably, a circumference of the inner wall of the cover is provided with positioning protrusions, and a plurality of positioning protrusions are provided, the plurality of positioning protrusions corresponding to the middle of the interior of a plurality of elastic bodies, and the interior of the plurality of positioning protrusions is provided with a first reserved mounting hole.

[0011] Preferably, a second reserved mounting hole is provided on one side of the first reserved mounting hole, and the connecting sleeve is disposed in the first reserved mounting hole.

[0012] Preferably, a reserved opening is provided at the middle position of the upper surface of the cover, one end of the mounting iron core extends to the reserved opening, and the other end extends through to the inside of the other side of the cover plate.

[0013] Preferably, an inner hole is provided at the middle position inside the mounting core, and the inner hole is integrally formed with the mounting core.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model divides the elastic body into two areas by matching the positioning position of the set elastic body with the positioning boss of the cover. Both sides of the positioning boss are elastic bodies, which can play a buffering role whether the engine rotates forward or backward. The design of the nylon petals of the nylon flying disc and the elastic body, with the elastic body sandwiched between the nylon petals of the nylon flying disc, allows the vibration during the transmission process to pass through two levels of shock absorption, reducing the vertical vibration generated during shaft transmission, effectively buffering the force received, and maximizing the avoidance of damage caused by rigid vibration of the component. It effectively avoids the problem in the existing flange coupling that the elastic element not only needs to be fixed between the connecting part and the two metal claw discs in the axial direction, but also needs to be connected between the elastic element and the iron core, which limits the radial buffering and shock absorption effect.

[0016] 2. Through the design of the nylon disc opening, T-shaped cavity and the outer wall of the connecting iron core step, there is no rigid connection between the nylon disc and the connecting iron core in the radial direction of the shaft, which results in a greater buffering and shock absorption effect in the radial direction of the shaft.
