Understanding the Cardan Joint: A Comprehensive Guide

The Fundamental Mechanism of the Cardan Joint

The Cardan joint is a significant mechanical component that exhibits varying rotational velocity outcomes derived from its input. This variation is a result of compliance in the joints. Higher compliance stiffness can result in more accurate tracking, albeit at the cost of increased internal torques and vibrations.

Structural Components and Functionality

The structural core of the Cardan joint is composed of metal-bis(terpyridyl). This core is furnished with rigid, conjugated linkers of para-acetyl-mercapto phenylacetylene. These linkers play a crucial role in determining the electrical contact in a two-terminal configuration using gold electrodes. The structure of the [Ru(II)(L)(2)](PF(6))(2) molecule incorporated in the joint is determined using single-crystal X-ray crystallography. This method has proven to yield a good agreement with calculations based on density functional theory (DFT).

Experimental Attributes

With the implementation of the mechanically controllable break-junction approach, the current-voltage (I-V) attributes of [Ru(II)(L)(2)](PF(6))(2) on a single-molecule level are derived under ultra-high vacuum (UHV) conditions at varying temperatures. These results are then juxtaposed with ab initio transfer calculations based on DFT. The simulations reveal that the Cardan joint's structural component controls the magnitude of the current. Moreover, fluctuations in the Cardan position have minimal impact on the positions of the steps in the I-V curve. Consequently, this results in the experimental I-V features that display the lowest-unoccupied-molecular-orbit-based conductance peaks at specific voltages, independent of temperature.

Cardan Joint Configurations

In the Cardan joint, the axes of the input and output shafts are deliberately offset at a predetermined angle. Notably, the angle of each universal joint is half of the angular offset of the input and output axes. Multiple joints can be employed to create a multi-articulated system, optimizing the efficiency and versatility of the component.

The Cardan Joint by WLY

WLY's Cardan Joint, similar in design and performance to the reputable MIB offshore soft-seated valves, is equipped with a sphere and seal assembly. This assembly allows the unit to align with any tensile or bending load applied to the hose. As a consequence, both the Minimum Bending Radius (MBR) and loads applied to the hose or connected components are significantly reduced.
