Tag Archives: Spring Coupling by Twin Spring Coupling

Twin Spring Coupling to replace servo couplings and universal joint

Spring couplings exist in a number of form, and vary widely in construction and capacity

Spring coupling with the coil end pressed into the hub is a cheap common spring coupling, but it cant run at high speed or take high torque and isnt flexible.

Spring Couplings like Beam couplings are high speed, low torque and low flexibility, commonly used in servo motors and pumps, its low torque and flexibility mean it has to be installed very precisely or it will fail quickly

Multi spring coupling like the Lovejoy Uniflex series is a number of springs layered together and welded onto the hubs, this means it cannot take high torque due to the welding process and is not very flexible.

Grid coupling is another coupling with a spring in its core, it can handle medium speeds and high torque but again isnt flexible past 1 degree or less, this means precise installation.

Twin Spring Coupling offers the best of all couplings without the downside, able to handle high speed, high angular misalignment and high torque makes it a clear winner amongst spring couplings.
