Flexible gear coupling for certification

What is flexible gear coupling?

Flexible gear couplings are mechanical devices used to connect two shafts at their ends to transmit torque and compensate for slight misalignments. They consist of two hubs with external teeth and a sleeve with internal teeth, creating a highly adaptable connection.

What are the different types of gear couplings?

Gear couplings come in various forms, each designed to suit specific applications and operational conditions.

Flanged gear coupling

Flanged gear couplings have flanged hubs that are bolted together, ensuring a secure and robust connection. They are commonly used in heavy-duty applications.

Continuous sleeve gear coupling

Continuous sleeve couplings feature a single sleeve that covers the entire length of the hubs, offering a more compact design with fewer components.

Half gear coupling

Half gear couplings are utilized in scenarios where space constraints are critical. They employ only one gear hub and one sleeve.

Floating shaft gear coupling

Floating shaft couplings are designed to accommodate longer distances between shafts by incorporating an intermediate shaft.

What is the difference between flexible and rigid coupling?

Flexible couplings and rigid couplings serve distinct purposes in mechanical systems.


Flexible couplings can accommodate misalignment and absorb shock loads, reducing wear on connected equipment.


Rigid couplings, as the name suggests, are inflexible and provide a solid connection, ensuring perfect alignment between connected shafts.


Flexible couplings are ideal for applications with variable alignment, while rigid couplings are best for precise, fixed alignments.

How to choose or customize the appropriate flexible gear coupling?

Choosing the right flexible gear coupling requires careful consideration of several parameters and operational conditions.

Torque requirements

Determine the maximum torque the coupling needs to transmit to ensure it can handle the load without failure.

Shaft sizes

Measure the diameters of the shafts to ensure compatibility with the coupling hubs.

Misalignment accommodation

Evaluate the degree of angular, parallel, and axial misalignment the coupling must compensate for.

Operational environment

Consider environmental factors such as temperature, exposure to chemicals, and humidity that may affect the coupling’s performance.

Material selection

Select materials that offer the required strength, durability, and resistance to wear and corrosion.
