CB and WB format selection
If the torque analysis of the shaft has already been performed, select C B or WB based on the results. If the torque analysis of the shaft has not been performed, follow the principles below:
a) For diesel engine-driven systems, please consult Schenck Engineering Department.
b) Motor-driven: If direct drive is used without gears and the vibration or impact originates from the motor side, then use WB; CB-type can also be used when it is more suitable.
c) Gear reducer: If the vibration or impact originates from the driven side, a WB-type is typically used; otherwise, a CB-type is employed.
d) Speed increaser: If the impact and vibration originate from the high-speed end, use the WB type; otherwise, if this is not the case, use the CB type.

Diaphragm coupling

The diaphragm coupling is a metallic flexible coupling that can compensate for deviations in the radial, axial, and angular directions. Compared to conventional diaphragm couplings, it features a compact structure, strong corrosion resistance inherent in the diaphragm itself, high load-carrying capacity, light weight, and suitability for high rotational speeds.

T-type and D-type diaphragm couplings

The diaphragm coupling compensates for the relative displacement between the two connected shafts through the elastic deformation of its diaphragm, making it a high-performance, metal-based flexible coupling with strong mechanical properties.

F-type diaphragm coupling

The F-type structure combines the advantages of both the R-type and G-type designs. For the same specification, the F-type has a greater shaft diameter capacity than the R-type and a smaller outer diameter than the G-type.

G-type diaphragm coupling

In addition to the key advantages of R-type couplings, the G-type coupling’s half-coupling features a larger shaft diameter capacity and can be manufactured with either straight bores or tapered bores (for hydraulic assembly and disassembly), or it can be conveniently connected to flanged shaft discs. The G-type is particularly well-suited for large electric motors, generators, or steam turbine units. Among all types of couplings, the G-type coupling is the easiest to assemble and disassemble.

R-type diaphragm coupling

The R-type structure ensures that the center of gravity on both sides is as close as possible to the support bearings of the two units, minimizing additional bending moments at the rotor shaft end and thereby promoting smooth, high-speed operation. The flexible components—comprising the half-coupling, diaphragm assembly, and protective sleeve—have been fully assembled prior to leaving the factory and are connected via a stop collar on the intermediate section, allowing for easy overall assembly and disassembly. Even after multiple reassemblies and disassemblies, this coupling maintains permanent alignment and dynamic balance. The large distance between the two flexible elements (diaphragms) enables the coupling to effectively absorb misalignment between the units. The intermediate section—being sufficiently long—can be removed to facilitate easy disassembly of the half-coupling from the shaft without requiring any movement of the entire unit (the same applies during installation). Shims at both ends of the intermediate section can be added or removed to compensate for installation errors and to conveniently achieve pre-tensioning, thereby accommodating thermal expansion or other dynamic misalignments of the units.

NUP New Elastic Sleeve Pin Coupling

The NUP flexible coupling’s elastomer material is made of polyurethane reinforced with graphite, offering excellent toughness, self-lubrication, and wear resistance. It features a hollow-grid design and comes in three different elasticity options, providing superior vibration absorption and impact resistance. The conical-bore bolts ensure a tight fit that remains secure and does not loosen over time. Thanks to its high safety and reliability, as well as its outstanding vibration absorption and impact resistance, this coupling has received unanimous praise from more than 100 users. As a result, it has been awarded innovation funds by the Ministry of Science and Technology of China, the Provincial Department of Science and Technology, and the Municipal Science and Technology Commission.

NUPEX Combination Flexible Coupling

The NUPEX combination elastomeric coupling is a high-performance coupling developed and launched onto the market in 2000 by Schenck Power specifically for the characteristics of variable-frequency drive units. After successful application at the Jinxi Petrochemical Plant, more than 300 units have been installed to date, all operating smoothly and delivering excellent results.

GCLD Type Spherical Tooth Coupling

The drum-type gear coupling is a type of rigid-flexible coupling that can compensate for misalignment along the radial, axial, and angular directions. Compared with straight-tooth couplings, it offers advantages such as a compact structure, a small turning radius, high load-carrying capacity, high transmission efficiency, low noise, and a long maintenance interval.

Compensating capacity for relative displacement between the two shafts of a drum-type gear coupling

1) When there is no radial displacement between the two shaft axes, the permissible radial misalignment △α is as follows: For each pair of meshing internal and external teeth in a gear-type coupling with drum-shaped teeth, the permissible angular misalignment △α is 1°30'.

Lx Elastic Pin Coupling

The Lx elastic pin coupling uses several non-metallic elastic pins inserted into the flange holes of the two coupling halves, thereby connecting the two halves via these pins. This coupling boasts a simple structure, is easy to manufacture, and allows for convenient installation, removal, and replacement of the elastic elements without requiring the two coupling halves to be moved.

Lz-type Elastic Pin-and-Tooth Coupling

The elastic pin-type gear coupling uses several pins made of non-metallic materials, which are inserted into mating holes between the two halves of the coupling and the inner surface of the outer ring. Torque is transmitted through these pins, thereby connecting the two halves of the coupling.
