Mechanical Power Transmission Disc Couplings Safety Warning. When using any of these products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this catalogue for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogues for proper...

Mechanical Power Transmission Disc Couplings jbj Techniques offer a wide variety of superior disc coupling products designed to meet the application needs of today’s worldwide power transmission market. Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, an innovative disc pack profile design has been developed, revolutionary to traditional disc pack designs found in the market. This disc pack can accommodate 1/2° to 1-1/2° of angular misalignment . Lovejoy disc packs are manufactured using high grade stainless steel (AISI-301), ensuring...

Mechanical Power Transmission Disc Couplings Industrial SU Type The SU Type coupling has a single flex plane with two hubs and a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are often combined with a shaft to make a floating shaft coupling. The shaft can be hollow for long light weight floating shaft couplings. Industrial SX Type This is the standard coupling type that includes two hubs, a stock length spacer designed to meet industry standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each disc pack, allowing this...

Mechanical Power Transmission Disc Couplings Disc Coupling Selection Process 1) Determine coupling type suitable for application. Angular, axial and parrallel misalignment properties need to be considered. Size will be determined by the selection torque and shaft diameters. 2) Next, calculate the application torque and apply the service factor to calculate the selection torque. Application torque Application torque x service factor = selection torque 3) Use the relevant table on the relevant page for model of coupling for torque rating and shaft size. Sometimes to have the right bore size it...

Service Factors Mechanical Power Transmission Disc Couplings Selection Procedure 1. Select the coupling type. 2. Select the driven machine service factor SFA from Table 1. 3. Select the driving machine service factor SFD from Table 2. Care should be taken when the driving machine is other than a standard electric motor or turbine. Some engines will impose extra fluctuations on the drive system and allowance should be made accordingly. Please refer to Table 2. A torsional coupling may be required for diesel drives. The two service factors SFAand SFD must be added resulting in the combined service...
