The TETRAFLEX coupling is designed with the following features:
– Binary symmetry which allows considerable conical misalignment.
– The rubber is precompressed from manufacture which limits operation under tension.
The floating star allows:
– Increased torque capacity without reducing the axial flexibility, hence reduced size for a given torque.
– Rotation at higher speeds as the star ensures that the arms are anchored centrifugally.
– A good torque/speed ratio.
