Product Description
A coupling is a device used to connect 2 shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
The primary purpose of couplings is to join 2 pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.
DJM 01 Shaft couplings are used in machinery for several purposes. The most common of which are the following.
- To provide for the connection of shafts of units that are manufactured separately such as a motor and generator and to provide for disconnection for repairs or alterations.
- To provide for misalignment of the shafts or to introduce mechanical flexibility.
- To reduce the transmission of shock loads from 1 shaft to another.
- To introduce protection against overloads.
- To alter the vibration characteristics of rotating units.
- To connect driving and the driven part
- To transfer power 1 end to another end.(ex: motor transfer power to pump through coupling)
Disc couplings transmit torque from a driving to a driven bolt tangentially on a common bolt circle. Torque is transmitted between the bolts through a series of thin, stainless steel discs assembled in a pack. Misalignment is accomplished by deforming of the material between the bolts.

Handling Torque and Torsional Stiffness in Disc Couplings
Disc couplings are engineered to handle high levels of torque and provide excellent torsional stiffness. The design of disc couplings allows them to transmit torque efficiently while maintaining their torsional rigidity. The flexible discs are designed to absorb misalignments and compensate for slight angular, axial, and radial deviations.
The discs themselves are precision-made with carefully calculated geometry, ensuring that they can transmit torque smoothly and evenly across their surface. The arrangement of multiple discs in a stack contributes to the coupling’s ability to accommodate high torque loads without sacrificing torsional stiffness.
Due to their torsionally stiff construction, disc couplings are capable of maintaining accurate shaft alignment even under significant torque transmission. This makes them suitable for applications requiring precise positioning, consistent torque transfer, and minimal backlash.
Impact of Number and Configuration of Disc Packs on Coupling Performance
The number and configuration of disc packs in a disc coupling have a significant impact on its overall performance. Here’s how:
- Number of Disc Packs: Increasing the number of disc packs can enhance the coupling’s torque capacity and stiffness. This allows it to handle higher levels of torque while maintaining its flexibility to accommodate misalignment.
- Configuration: Different configurations, such as single-flex, double-flex, or multiple-flex, offer varying degrees of angular misalignment compensation and torsional stiffness. Single-flex configurations provide greater misalignment capacity, while double-flex configurations offer improved torsional stiffness.
Choosing the appropriate number and configuration of disc packs depends on the specific application requirements:
- Torque Transmission: Applications with high torque demands may benefit from a higher number of disc packs to ensure reliable torque transmission.
- Misalignment Compensation: Applications with moderate misalignment may opt for configurations that offer higher angular misalignment compensation.
- Torsional Stiffness: For applications where torsional stiffness is critical, a configuration with multiple-disc packs may be preferred.
- Space Limitations: Consider the available space and coupling dimensions when choosing the number and configuration of disc packs.
- Dynamic Behavior: Depending on the application’s dynamic behavior and vibration characteristics, the appropriate configuration can be selected to minimize resonances.
Ultimately, the selection of the number and configuration of disc packs in a disc coupling should be based on a thorough understanding of the application’s torque, misalignment, and stiffness requirements to optimize coupling performance and reliability.
Types of Disc Couplings for Specific Uses
Disc couplings come in various designs and configurations, each tailored to specific use cases and requirements. Here are some different types of disc couplings designed for specific applications:
- Single Disc Couplings: These couplings consist of two hubs and a single flexible disc element. They are suitable for applications where angular misalignment compensation is the primary requirement.
- Double Disc Couplings: These couplings include two flexible disc elements and three hubs. They provide higher torsional flexibility and axial movement absorption, making them suitable for more demanding applications.
- Spacer Disc Couplings: Spacer disc couplings incorporate a spacer between the flexible disc elements. This design allows for greater axial movement and misalignment compensation.
- Close-Coupled Disc Couplings: These couplings have a compact design with minimal spacing between the hubs and discs. They are commonly used in applications where space constraints are a concern.
- Floating Shaft Disc Couplings: Floating shaft disc couplings are designed for applications where there is a need to connect shafts that are not in the same plane. They can accommodate both angular and axial misalignment.
- High-Speed Disc Couplings: These couplings are specifically engineered to handle high rotational speeds while maintaining precise alignment and minimal vibration.
- Heavy-Duty Disc Couplings: Heavy-duty disc couplings are built to transmit extremely high levels of torque and are often used in demanding industrial applications.
- Customizable Disc Couplings: Some manufacturers offer customizable disc couplings that can be tailored to specific application requirements, such as material selection, size, and design parameters.
The choice of disc coupling type depends on factors such as the level of misalignment, torque transmission requirements, space constraints, and environmental conditions. Selecting the appropriate type ensures optimal performance and reliability in various machinery applications.
