AI Technical Summary
Technical Problem
Existing couplings for joining drive shafts are expensive and labor-intensive due to complex shapes and high geometrical tolerance requirements, and they fail to accommodate off-axis axial or bending movements effectively.
Method used
A flexible coupling design using compliant components, such as coil springs or resilient bushings, that can absorb axial and lateral deviations between shafts, allowing for torque transmission while accommodating bending and axial movements, and is easier to manufacture without strict geometrical tolerance and welding.
Benefits of technology
The flexible coupling efficiently transfers torque and adapts to misalignments, reducing manufacturing costs and complexity while maintaining operational performance.
