Rokee® Customized Diaphragm Coupling With Expansion Sleeve for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
Diaphragm coupling with expansion sleeve, also known as diaphragm expansion sleeve coupling or expansion sleeve diaphragm coupling, is a mechanical connecting component mainly used to connect two shafts (driving shaft and driven shaft) in different mechanisms, so that they rotate together to transmit torque.
The diaphragm coupling with expansion sleeve mainly consists of the following components:
Stainless steel metal diaphragm group (steel sheet): As an elastic element, it is used to compensate for the relative displacement between two axes.
Half coupling: It is connected to the driving shaft and the driven shaft respectively, and is the main component for torque transmission.
Locking cover plate, Z1 type expansion sleeve, and clamping element: These components work together to achieve keyless connection and expansion fixation of the coupling.
Bolts, anti loosening nuts, and limit washers: used to ensure the stability and reliability of the coupling, prevent loosening and displacement.
The torque is input from the active half coupling, transmitted to the flexible steel plate group (stainless steel metal diaphragm group) through high-strength bolts, and then output through the intermediate sleeve and the driven half coupling. This structural design effectively avoids the sliding loss of traditional couplings and improves transmission efficiency.
Characteristics and advantages
No relative sliding: avoids the wear caused by sliding of traditional couplings and extends their service life.
No lubrication: No need to regularly add lubricating oil, reducing maintenance costs.
No noise: significantly reduces noise during operation, suitable for environments with high requirements for quietness.
Easy disassembly and assembly: With the Z1 type expansion sleeve, keyless connection is achieved, simplifying the installation and disassembly process.
Compensation performance: It has varying degrees of axial, radial, and angular compensation performance, and can adapt to relative displacement between two axes.
High precision: Compact structure, high precision, suitable for high-speed operation.
Strong bearing capacity: able to withstand large torque and axial, radial, and angular loads.
Diaphragm couplings with expansion sleeves are widely used in industries such as papermaking, metallurgy, textiles, shipbuilding, agricultural machinery, transportation, chemical engineering, light industry, as well as high-speed and heavy-duty power transmission systems such as CNC machine tools, generator sets, and compressor sets. Its excellent performance and adaptability make it an important component in the field of mechanical transmission.
