Power Transmission couplings replacement technology.

Replace Universal joints, Jaw couplings, Elastomeric couplings and Spring couplings.

Twin Spring Coupling is the latest in power transmission coupling design, jaw couplings and elastomeric couplings all work at high speed but low angle of misalignment. On the other end universal joints are able to handle higher amounts of misalignment but at lower speeds and constant bearing replacement. Twin Spring Coupling as a hybrid flexible shaft coupling can do both. Improving on existing coupling technology we provide a number of different versions which allows up to 45° operational angle of usage

    • No internal components – No components to be constantly maintained, greased and replace, this saves you time and money.
    • Dual spring design absorbs vibration
    • One Piece design means no broken yokes or hubs.
    • Capable of angular, radial and axial misalignment.
    • Nominal torque of up to 500ft lbs. 495Kw, 6000 In lbs.
    • Flexible to 45°
    • High speed- Runs at up to 7000 RPM.
    • Torsional rigidity at low angles of misalignment
    • Scalable – the Twin spring unit can be scaled up or down to suit individual customer requirements.​
    • Different shaft types or sizes, we do AGMA/ANSI, SAE, & DIN bore/keyway and spline bore’s.
    • Being made from two counter wound springs means it absorbs shock force without damage
    • Spring design allows greater angle of misalignment without damaging components​
    • ISO9001 2007 manufactured

The patented twin spring design allows for larger angle of usage without deformation with the torque transfer seen with Universal Joints, giving the performance of a Universal joint without the constant maintenance of friction or needle bearings.

So how does it work? The design is quite simple, the sets of springs are counter-wound so one tightens while the other loosens and visa versa. This allows the coupling to work in both forward and reverse. Its simplicity doesn’t end there, the only thing in the center of the coupling is a single ball bearing this allows the coupling to pivot allowing for maximum flexibility, this means no bearings. We have now added a single direction version, both springs running in the same direction, increasing the life and torque of the coupling.

Bearings/Spider inserts – are a constant maintenance item, greasing bearings every 8/40/200 hours, inspect and replace, they cannot run in harsh environments like water, mud, sand, dust and dirt as any intrusion by any of those elements leads to rapid failure. So no bearings means no constant maintenance. Elastomeric spiders wear at 1° of misalignment or less, and compress over time so both wear and need replacement.

One piece design – As the product is just hubs and springs the things that can go wrong are greatly reduced, so no cracked yokes or broken propeller joints, no worn out bearings, or spider inserts.

Coupling Torque – the bigger the better, our power transmission coupling is powered by the springs, but because it is a pair of springs it effectively is a metal bar, add the ball bearing it turns into a flexible metal bar.

So this means more torque and still have the flex that would destroy a standard universal or constant velocity joint. High speed/low speed – Now power transmission coupling technology is split into 2 main areas, high speed, low torque, small angle of misalignment and lower speed, higher torque, higher angle of misalignment.

Different couplings applications, same product – Flexible/High speed couplings are Elastomeric couplings and jaw type couplings which can run at high speed maintain torsional rigidity but traditionally can only run at less than 1 degrees of misalignment before starting to wear out.

Add to that because of that small misalignment angles , the amount of torque these flex couplings can handle is quite small.

Twin Spring’s power transmission coupling retains torsional rigidity at lower angles at high speed, with far more torque than say a standard beam coupling, with the added flexibility if needed.

Lower speed power transmission couplings like universal joints can work at high torque and larger degrees of misalignment but they have internal components that need to be constantly maintained. If not greasing for lubrication and bearing replacement and the angles of misalignment they can work at is limited as well, as too much will lead to bearing failure. Our power transmission coupling can meet the higher torque demands and the increased flexibility while needing no maintenance as you would have to with using universal joints.

One product multiple uses. Why would you use different products if you didn’t need to when one product will do it all, a no maintenance, high speed, high torque, higher angle of misalignment capable flexible coupling. Three models and counting – To date we have 3 models the TSC150, TSC300 and the TSC500. TSC150 is capable of handling 150ft lbs of torque. TSC300 is capable of handling 300 ft lbs of static torque. TSC500 can handle 500ft lbs of static torque .

We are looking at what the market demands so bigger or smaller we will be adding more as time goes on. We have all the splines and keyways you need to fit your equipment. We want to work with you, so contact us and lets work together to solve your mechanical power transmission couplings issues today.
