Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a universal adjustable coupling. Background Technique

[0002] A coupling refers to a device used to connect two shafts. It can transmit power and torque, enabling the two shafts to rotate simultaneously without being affected by offset and tilt. A coupling usually consists of two shaft sleeves and an intermediate connecting component. The intermediate connecting component can be a gear, a spring, a chain, etc. In the process of using a coupling, a universal adjustable coupling is usually required. Among them, the "universal coupling" disclosed in the application number "CN202790176U" has solved various drawbacks of the existing coupling device, such as the shafts and bearings inside being prone to wear, resulting in an increase in the backlash of power transmission and a decrease in the operating accuracy of the equipment. After further retrieval, it is found that the "universal coupling" disclosed in the application number "CN103267067A" has effectively solved technical drawbacks such as a small included angle between the axes of the device and the inability to meet the requirement of large rotation angles through specific technical structure settings. However, in actual use, universal adjustable couplings with similar structures still have many defects, such as: it is not convenient to adjust the installation length according to the situation, and the applicable range is small; and it is not convenient to quickly disassemble the coupling, making it inconvenient to use. Therefore, a universal adjustable coupling needs to be designed. Content of the Utility Model

When the device needs to be disassembled, the staff can connect the oil inlet hose to an external hydraulic oil pump and send hydraulic oil into the oil pressure chamber through the oil inlet, so as to perform hydraulic disassembly on the coupling and the transmission shaft, which is beneficial for the staff to quickly disassemble the device, reducing the time and effort required for disassembly and improving the functionality and convenience of the device.

[0007] Preferably, the top of the fixed housing and the connecting column are provided with limit holes, and the top of the connecting column is engraved with scale lines. The staff can install the threaded rod through the limit holes, and the scale lines can assist the staff in judging the connection length of the coupling.

[0008] Preferably, a connecting shaft is rotatably installed inside the first connecting block, and a second connecting block connected to the connecting shaft is fixedly installed on the other side of the coupling structure.
