Synthesis of Swing Type Flexible Coupling through Denavit-Hartenberg Notations

Abstract

This paper synthesizes a swing-type flexible coupling (STFC) utilizing robotic kinematics' Denavit-Hartenberg (DH) nomenclature. The study aimed to design a coupling for dynamic misalignments to maintain efficient torque transmission for applications like robotics, automotive engineering, and industrial machinery. Links are defined by joint angle, offset, length, and twist in DH notation, simplifying multi-link mechanical systems. This notation helps engineers visualize the STFC's kinematic behavior for flexibility, torque loss reduction, and mechanical wear from misalignments. The paper outlines the STFC coupling's design specifications, including angular misalignment management, torsional rigidity, and vibration dampening. A dynamic examination of the synthesized connection shows how rotational forces affect dowel pins and central main pins. Results show that coupling's kinematic positions and dynamic behaviors highlight its stability and adaptability.  Results show that the STFC works in dynamic systems with frequent shaft misalignments during its 360-degree rotation. This paper introduces DH notation's innovative usage in flexible coupling design and provides a formal optimization technique. Future research could improve DH settings for complex conditions and add durable materials. The synthesis of this connection helps to build strong, flexible couplings for high-performance mechanical systems.
