Twin Spring Coupling—a New York startup—has released the data on their new drivetrain coupling technology’s first
commercial product the TSC8300.
The TSC8300 is warrantied to 300 ft. lbs. (407 Nm) of torque. It will allow customers with smaller torque requirements to
also get increased torque flexibility in one product.
The patented technology will allow designers who use existing coupling technology like cardan, CV and universal joints to
look at their designs differently.
“Increased flexibility with the same torque curves allows the designer/engineer to achieve increased reliability with
little to no modification,” says Darren Finch CEO of Twin Spring Coupling.
The constant maintenance of the internals of a universal joint isn’t a factor with this coupling as there are no internal
components—no needle bearings to maintain, no bearings to wear out. Applications include axle, PTO, drive shaft, steering,
conveyor belts, belts, pumps, etc.
The simple design allows the coupling to be scaled up or down to suit the application and torque requirements. The
flexibility of the springs allows for more movement without damaging the drive shaft or components. At the same time, it is
able to absorb shock and energy, making the coupling more efficient.
“We are working on larger versions to handle over 500 ft. lbs. (674 N.m) and 700 ft lbs (950 N.m) of torque, and will
continue to develop our product line, working with customer and supplier needs,” Finch added.
