The laser power generated by patented beam coupling of fibre lasers was successfully demonstrated for the first time in the world.
Key elements of the optical system include the beam path design with its maximum optical precision and the uncompromising concentration on the essentials, the beam combiner system for extremely accurate beam coupling and superimposition, the beam splitter with continuous and loss-free splitting of the light spectrum and, last but not least, the extremely stable pinhole.
The multiple cut design provides higher torsional stiffness and torque capabilities, and greatly reduced wind-up when compared to a commodity-type single beam coupling. The multiple spiral cuts also allow the couplings to accomodate angular misalignment, parallel misalignment, and axial motion.
The bellows flexible coupling has the best torsional stiffness -- [greater than] 22,000 ounce-inches per radian -- followed by the slotted radial beam coupling at 16,000 ounce-inches per radian.
Ruland Manufacturing Company (Marlborough, MA) has introduced a new clamp design for its zero-backlash flexible beam couplings. The couplings now clamp with a single screw on each end, which eases installation, and are balanced for increased RPM capability.
Helical claims that it is the only company to manufacture beam couplings out of 17-4PH stainless steel.
Ruland Manufacturing (Marlborough, MA) has introduced a new clamp design for its zero-backlash flexible beam couplings. The couplings now clamp with a single screw on each end, which eases installation, and are balanced for increased i rpm capability.
Depending on the type of motors and the connection required, this style application could utilize the miniature disk, bellows, and beam couplings.
