A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other.
Beam couplings are a versatile coupling that can provide excellent characteristics if applied correctly. Many factors must be considered in the selection of the right coupling for an application. Understanding these factors can lead to reduced coupling failure and better system performance.
Selecting the Proper Beam Coupling for an Application (1) Physical Space Requirements (2) Misalignment (3) Environmental Considerations (4) Operating Conditions (5) Performance Criteria
