Twin Spring Coupling is the latest in multi directional flexible coupling design, forget your old Uni joints or fragile CV joints. Servo coupling run at high speed but can handle no torque, we can handle both.
Improving on existing coupling technology we provide a number of different versions which allows a 0 to 35° angle of usage
No internal components - No bearings to be constantly lubricated, this saves you time and money.
High speed- Runs at up to 8000 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, no problem, we do all standard sizing.
Being made from two counter wound springs means it absorbs shock force without damage
Spring design allows greater angle of usage without damaging components
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 with the flexibility of a Constant Velocity joint and more.
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.
The simplicity doesnt 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 flexibility that would destroy a standard universal or constant velocity joint.
High speed/low speed - Now flexible 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.
High speed flexible couplings are Beam couplings, elastomeric, bellows couplings and jaw 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 flexible 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 and constant velocity (CV) joints can work at high torque and larger degrees of misalignment but they have internal components that need to be constantly maintained and the angles of misalignment they can work at is limited as well, as too much will lead to bearing failure. Our 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.
Two models and counting - To date we have 2 models the TSC300 and the TSC500. The TSC300 is capable of handling 300 ft lbs of static torque and operate at angles of over 30° (no power applied 60°) 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.
