Coupling replacement for Spicer, Lovejoy, Beam, Bellows and Jaw type couplings

Twin Spring Coupling is the latest in coupling design, beam couplings, bellows coupling and jaw coupling all work at high speed but low angle of misalignment, universal joints are able to handle higher amounts of misalignment but at lower speeds and constant maintenance. Twin Spring Coupling as a hybrid flexible coupling can do both.

Improving on existing coupling technology we provide a number of different versions which allows a 0 to 25° angle of usage

  • No internal components – No bearings to be constantly lubricated and replace , this saves you time and money.
  • One Piece design means no broken yokes or hubs.
  • High speed- Runs at up to 6000 RPM
  • Torsionally rigid at low angles of misalignment
  • Scalable – the Twin spring unit can be scaled up or down to suit individual customer requirements.​
  • Customizable – Have a specific form/function the spring/ball settings can be changed to fit most applications.
  • 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 usage 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.

    So how does it work? The design is quite simple, the sets of springs are counterwound 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.

    Bearings are a constant maintenance issue, 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 or worse 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.

    Torque – the bigger the better The flexible 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 flex 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.

    Flexible/High speed couplings are Beam couplings, elastomeric, bellows couplings and jaw type couplings which can run at high speed maintain torsional rigidity but traditionally can only run at a few 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 flexible coupling remains torsionally rigid at lower angles at high speed, with far more torque than say a standard beam coupling, with the added flexibility if needed.

    Lower speed 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 (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 flex 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 didnt 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. The TSC150 is capable of handling 150ft lbs of torque and be used at 30°. The TSC300 is capable of handling 300 ft lbs of static torque and operate at angles of 30° the 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, as for splines we can work with you to make any spline you need to fit your equipment.
