1 Basic Structure and PrincipleThe expansion sleeve dual-mode disc coupling is mainly composed of a sleeve, expansion sleeve, key, two mold discs and other components. Its working principle is to generate a huge clamping force between the inner ring and the shaft, and between the outer ring and the wheel hub through the action of high-strength tension bolts, thereby achieving keyless connection between the components and the shaft. When subjected to load, torque, axial force, or a composite load of the two is transmitted through the combined pressure and frictional force generated by the expansion sleeve and the components or shafts.
2. Main features
Simple structure and easy installation: The expansion sleeve coupling has a simple structure, high reliability, easy installation and disassembly, and does not require specialized tools.
High torque transmission: Due to the large difference in diameter between the expansion sleeve and the sleeve, it can transmit a large torque of 3.
Strong correction ability: The coupling has high correction ability, low moment of inertia, can absorb vibration, and the middle diaphragm compensates for angular and axial deviations.
Wide applicability: Expansion sleeve couplings have been widely used in industries such as metallurgy, mining, steel, papermaking, cement, food, and light industry.
Protection equipment: It can protect the equipment from damage when overloaded.
3. Application Fields
Expansion sleeve dual-mode disc couplings are widely used in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment and other fields. Especially in situations where heavy loads need to be transmitted and high-precision requirements are needed, its performance is particularly outstanding.
4. Installation and maintenance
During installation, it is necessary to ensure that the two flanges of the coupling are parallel and within the allowable tolerance range to avoid bending stress. Meanwhile, during the installation process, necessary adjustments need to be made to the bearings to ensure the alignment accuracy of the coupling connection. In terms of maintenance, regular rust prevention treatment should be carried out on the expansion sleeve end face and bolts, and the exposed expansion sleeve end face and bolts should be maintained on machines operating outdoors or in poor working environments.
5. Precautions
During installation and disassembly, it is necessary to strictly follow the instructions or specifications to avoid damaging the coupling or related components.
Regularly check the operating status of the coupling, promptly identify and address potential issues.
During use, overloading or prolonged operation in harsh environments should be avoided to extend the service life of the coupling.
Please note that the above information is for reference only. In practical applications, appropriate coupling models and specifications should be selected based on specific needs and equipment requirements, and relevant installation and maintenance specifications should be followed. If necessary, please consult a professional engineer or manufacturer for more detailed information.
