AI Technical Summary
The direct fixed connection method of existing couplings is prone to scratch the shaft and is difficult to separate during maintenance, resulting in difficulty in disassembly.
The clamped coupling body and the semi-coupling body are designed through internal threaded slots and structural designs, such as opening screws, protective gaskets, fixing bolts, etc., to achieve rotatable disassembly to avoid interference fit.
The coupling and shaft body are easily separated, avoiding the difficult disassembly caused by interference coordination, and improving the convenience of maintenance.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a combined coupling. Background Art
[0002] The coupling is mainly used to connect the driving shaft and the driven shaft in different mechanisms to make them rotate together to transmit torque. It is an important part of the mechanical transmission system. Couplings have been widely used in general machinery, metallurgical equipment, chemical machinery, aviation, ships, electronic equipment and other fields.
[0003] After searching, a Chinese patent with publication number CN 213393211 U mentioned a combined coupling, which relates to the technical field of couplings and includes a left coupling body, a right coupling body and a plum blossom elastic member. The two adjacent end faces of the left coupling body and the right coupling body are fixedly connected with a plurality of convex teeth matching the plum blossom elastic member. The plum blossom elastic member is arranged between the left coupling body and the right coupling body. The utility model improves the rigidity of the plum blossom elastic member by arranging a U-shaped elastic skeleton in the cavity of the plum blossom elastic member, avoids excessive deformation of the plum blossom elastic member during use and causes cracks in the plum blossom elastic member, thereby improving the service life of the coupling, and through the arranged spring, through the elastic force of the spring, enhances the elasticity of the U-shaped elastic skeleton, makes it easier for the U-shaped elastic skeleton to return to its original state after deformation, improves the service life of the U-shaped elastic skeleton, and further improves the service life of the coupling.
[0004] The above device uses a directly fixed coupling device to connect the shafts. On the one hand, this connection method is relatively simple, and because the screws are in direct contact with the shaft, it is easy to scratch the shaft. On the other hand, due to the interference fit between the shaft and the coupling, it is difficult to separate the coupling from the shaft during maintenance. Utility Model Content
[0005] The purpose of the utility model is to provide a combined coupling to solve the problems raised in the above background technology.
[0006] In order to solve the above problems, the technical solutions adopted by the utility model are as follows:
[0007] A combined coupling comprises a clamping coupling body and a first half coupling body fixedly arranged at one end of the clamping coupling body, a slit is provided on one side of the outer wall of the clamping coupling body, an internal threaded slot is provided on the outer wall of the clamping coupling body above the slit, a spreading screw is movably connected inside the internal threaded slot, a second half coupling body is provided above the first half coupling body, and the first half coupling body is installed and connected to the second half coupling body through a fixing component.
[0008] Preferably, the clamping coupling body and the first half coupling body are integrally formed.
[0009] Preferably, a mounting slot is provided on the bottom wall of the slot, a protective gasket is fixedly installed inside the mounting slot, and the protective gasket is arranged below the end of the support screw.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] When a person needs to separate the coupling from the shaft body, the person utilizes the characteristic of the internal threaded slot having a splay screw in the movable connection, and then rotates the splay screw so that the lower end of the splay screw presses against the protective gasket, thereby further forming a gap between the clamping coupling body and the first half coupling body and the outer wall of the shaft body, thereby facilitating separation and avoiding interference fit between the coupling and the shaft body that makes disassembly difficult.
