The Reli-a-Flex flexible shaft coupling is claimed to be in a class of its own for high torsional stiffness, low kinematic error and long life.
The Reli-a-Flex flexible shaft coupling is claimed to be in a class of its own for high torsional stiffness, low kinematic error and long life.
In comparison with a spiral beam coupling the Reli-a-Flex coupling achieves up to: 16 times greater torsional stiffness; 12 times less transmission error; and 12 times less bearing load.
This along with unsurpassed reliability makes the Reli-a-Flex coupling an excellent choice for accurate measuring and responsive precision motion control, both for servos and steppers, and allows feedback devices to operate to new and higher standards.
Unlike any other one-piece flexible shaft coupling on the market with its unique patented double slit pattern the Reli-a-Flex coupling was specifically designed by Reliance Engineers because no other coupling met the exceptionally demanding performance criteria required for their own motion control solutions.
Reliance specialises in the design, manufacture and test of high accuracy mechatronic assemblies for position measurement and feedback applications in the aerospace, medical, biotechnical, analytical, scientific instrument and defence industries.
Shaft couplings very often play a crucial role in these high integrity and ever more demanding applications.
Failure of these couplings can have a catastrophic effect on the parent machine, in the form of a total loss of drive or position sensing.
Tested to 50,000,000 fatigue cycles, at its rated torque and 80% maximum offset, the Reli-a-Flex coupling outperforms all other one piece couplings on the market and gives predictable performance.
