Coupling considerations for designers

Author : David Lockett, Huco

07 October 2022

For designers, spending time selecting the perfect coupling may be low on the priority list. However, ensuring an efficient and reliable connection between two shafts is paramount for system reliability and to avoid any costly redesigns. Here, David Lockett, Managing Director at Huco, explores the considerations for designers when specifying couplings.

The right time to think about couplings
While sometimes overlooked, specifying a suitable coupling solution can have a major impact on the overall performance of the powertrain. Once the main elements of the powertrain have been specified, it’s important to review coupling options to see how the relative performance of different styles may complement your overall design.

When development schedules are tight, designers may be tempted to specify the most easily available coupling type. This may be a false economy, as the wrong coupling could lead to problems such as premature wear of components, poor efficiency, vibrations, or inadequate torque to turn the shaft and coupling. This necessitates a costly and time-consuming redesign process.
