Which type of coupling features a serpentine spring?

The type of coupling that features a serpentine spring is the grid coupling. This design utilizes a flexible grid, which is typically composed of multiple serpentine-shaped spring elements that can accommodate misalignments between connected shafts. The grid allows for flexibility while transmitting torque, providing shock absorption and reducing the impact of vibrations, which is particularly advantageous in high-speed or variable load applications.

Grid couplings are known for their robust performance and ability to handle significant amounts of axial, radial, and angular misalignment. This characteristic makes them suitable for a variety of industrial applications where flexibility and durability are crucial.
