Detailed introduction
The F-type structure combines the advantages of the R-type and G-type. For the same specifications, the F-type has a larger shaft diameter capacity than the R-type and a smaller outer diameter than the G-type.
The F-type coupling is particularly well-suited for large-scale units operating at speeds below 10,000 rpm, and is especially ideal for applications requiring quick assembly and disassembly.
Its structural type is shown in Figure 2.3, and the technical parameters and main dimensions are listed in Table 2-2 and Table 2-3.

The diaphragm disc coupling is a type of metal flexible coupling that offers compensation capabilities for radial, axial, and angular misalignments. Compared to conventional diaphragm couplings, it features a compact design, inherent strong corrosion resistance from the diaphragm disc itself, high load-bearing capacity, lightweight construction, and suitability for higher operating speeds.
T-Type and D-Type Diaphragm Couplings
The diaphragm coupling uses the elastic deformation of its diaphragm to compensate for the relative displacement between the two shafts it connects, making it a high-performance, flexible coupling with robust metal components.
The F-type structure combines the advantages of the R-type and G-type. For the same specifications, the F-type has a larger shaft diameter capacity than the R-type and a smaller outer diameter than the G-type.
In addition to the key advantages of R-type couplings, the G-type half-coupling offers greater shaft-diameter capacity and can be manufactured with either straight bores, tapered bores (for hydraulic assembly and disassembly), or easy-to-connect flanged hubs. The G-type is particularly well-suited for large electric motors, generators, or steam turbine units. Moreover, G-type couplings are among the most convenient to assemble and disassemble of all coupling types.
The R-type structure ensures that the center of gravity is positioned as close as possible to the support bearings on both sides of the unit, minimizing additional bending moments at the rotor shaft end—thus promoting smooth, high-speed operation. The flexible components (including the half-coupling, diaphragm assembly, and protective sleeve) are pre-assembled as a complete unit before leaving the factory and are connected to the intermediate section via a precisely aligned stop feature, allowing for easy overall assembly and disassembly. Importantly, this design maintains permanent alignment and dynamic balance even after multiple reassemblies. Additionally, the large distance between the two flexible elements (diaphragms) enables the coupling to effectively accommodate misalignment between the units. The intermediate section, designed with sufficient length, can be easily removed from the shaft, enabling convenient disassembly of the half-coupling without requiring any movement of the entire机组—this also applies during installation. Finally, shims at both ends of the intermediate section can be added or removed to compensate for installation inaccuracies, while simultaneously facilitating precise pre-tensioning to absorb thermal expansion or other types of dynamic misalignment in the system.

The NUP flexible coupling features a material made from polyurethane combined with graphite, offering excellent toughness, self-lubrication, and wear resistance. Its hollow-grid design provides three elasticity options, enhancing vibration absorption and impact resistance.

Thanks to its exceptional safety and reliability, along with superior vibration-damping and shock-absorbing capabilities, this coupling has earned unanimous praise from over 100 users. As a result, it has received innovation funding awards from China’s Ministry of Science and Technology, the Provincial Department of Science and Technology, and the Municipal Science and Technology Commission.
