Description

Technical Field

[0001] The utility model belongs to the technical field of coupling devices, and specifically refers to a quick-release serpentine spring coupling. Background Art

[0002] The serpentine spring coupling is a kind of advanced metal structure. It transmits torque by serpentine spring plates. The main structure of the serpentine spring coupling consists of two half couplings, two half casings, two sealing rings and serpentine spring plates. It transmits torque by the serpentine springs being embedded in the tooth grooves of the two half couplings. The coupling realizes the connection between the driving shaft and the driven shaft by the serpentine spring plates being embedded in the tooth grooves of the two half couplings.

[0003] However, most of the existing serpentine spring couplings use two semi-cylindrical shells buckled together to cover the serpentine spring plates. Due to the gaps at the joints and frequent rubbing, when the serpentine spring coupling rotates, the friction increases and it is easy to be damaged. And gaskets are needed and are prone to dislocation, making the loading and unloading troublesome and unable to achieve quick disassembly. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a quick-release serpentine spring coupling, which effectively solves the problems that most of the serpentine spring couplings use two semi-cylindrical shells buckled together to cover the serpentine spring plates. Due to the gaps at the joints and frequent rubbing, when the serpentine spring coupling rotates, the friction increases and it is easy to be damaged. And gaskets are needed and are prone to dislocation, making the loading and unloading troublesome and unable to achieve quick disassembly.

[0005] The technical solution adopted by the utility model is as follows: A quick-release serpentine spring coupling provided by the utility model includes a connecting shaft, a quick-disassembly structure and a serpentine spring connection structure. The quick-disassembly structure is arranged on the connecting shaft, and the serpentine spring connection structure is arranged on the connecting shaft. The quick-disassembly structure includes a first limit seat, a housing, a clamping seat, a second limit seat, an outer hoop, an inner clamping groove, a threaded seat and a bolt. The first limit seat is wrapped around the connecting shaft, the housing is detachably arranged through the connecting shaft, the clamping seat is fixedly arranged at the front end of the housing, the second limit seat is arranged at the rear end inside the housing, the outer hoop is detachably wrapped around the clamping seat, the inner clamping groove is arranged on the inner side of the outer hoop, the threaded seat is fixedly arranged at the connecting port of the outer hoop, and the bolt is threadedly arranged through the threaded seat.

[0006] Preferably, the serpentine spring connection structure includes a coupling clamping seat, a coupling clamping groove and a serpentine spring. The coupling clamping seat is fixedly arranged on the outside of the connecting shaft, the coupling clamping groove is recessed on the coupling clamping seat, and the serpentine spring is snap-fitted into the coupling clamping groove.

[0007] In order to better achieve the effect of reducing friction, the gap at the sealing part of the housing is in the same rotation direction as the serpentine spring and the coupling clamping groove on the connecting shaft.

[0008] For the purpose of achieving accurate positioning more quickly, the second limiting seat is outwardly a convex angle, and the first limiting seat is inwardly a concave angle.

[0009] Furthermore, the outer hoop is semicircularly arranged.

[0010] To achieve the effect of quick disassembly, the bolt adopts a single-sided thread fixing structure.

[0011] With the above structure, the beneficial effects obtained by the present utility model are as follows: A quick-disassembly serpentine spring coupling proposed by this solution has two outer shells sleeved outside the serpentine spring and the coupling seat. At this time, the gap at the connection is in the same direction as the rotation direction of the coupling seat and the coupling groove, avoiding friction. At the same time, the gasket is clamped between the two outer shells, with direct docking, which is fast and convenient. At the same time, two outer hoops are directly buckled on the outer card seats of the outer shells to clamp the two outer shells, realizing quick loading and unloading. Description of the Drawings
