Wb-Type Rubber Block Coupling

The elastomeric coupling can transmit high torque and absorb rotational shocks in the unit, requires no lubrication, is easy to install and disassemble, and performs reliably even in harsh conditions such as humidity, sand, high temperatures, and other challenging environments—while demanding minimal maintenance and helping extend the lifespan of the equipment.

Detailed introduction

Product Features
The mechanical rubber block coupling can transmit high torque and absorb rotational shocks in the unit, requiring no lubrication, while being easy to install and disassemble. It performs reliably even in harsh environments such as wet, sandy, high-temperature conditions—and other challenging settings—while demanding minimal maintenance and helping extend the lifespan of the equipment.
 
Application scenarios
Suitable for units with large moments of inertia, significant torque fluctuations, operational shocks, and reciprocating motions.
 
Wb-Type Rubber Block Coupling
The WB-type rubber block coupling is primarily used in applications involving high torque, severe shock loads, or reversible machinery, and it features a relatively small angular deformation (1° to 2°). Its structural designs are shown in Figures 5.1 and 5.2, while technical parameters and key dimensions are listed in Table 5-1.
 


CB and WB format options
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 done, follow the principles below:
a) For diesel engine-driven systems, please contact Schenck Engineering Department.
b) Motor-driven operation: If direct drive is used without gears and any vibration or shock originates from the motor side, WB should be employed; CB-type options are also acceptable when more suitable.
c) Gearbox: If the vibration or shock originates from the driven side, a WB-type is typically used; otherwise, a CB-type is recommended.
d) Speed Increaser: Use the WB type if the impact and vibration originate from the high-speed end; otherwise, use the CB type.

Diaphragm Disc Coupling

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.

F-type diaphragm coupling

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.

G-Type Diaphragm Coupling

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.

R-Type Diaphragm Coupling

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.
