AI Technical Summary
Traditional couplings cannot effectively adapt to axial, radial, or angular displacements when faced with inter-shaft displacements, leading to increased stress, accelerated component wear, and even shaft breakage or coupling damage. Furthermore, flexible couplings are prone to fatigue failure under frequent displacements, affecting transmission reliability.
Design a sliding coupling that uses a buffer section between the left and right coupling parts and multiple sets of horizontal and vertical rods that are interference-fitted with the vertical and horizontal grooves to achieve power transmission and adjustment, adapting to the installation requirements of different structures.
It reduces stress concentration, extends equipment service life, improves transmission reliability, and adapts to various installation environments under inter-shaft displacement conditions.
