โฃABENICS: Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshing.
The gear-based joint drives three rotational degrees of freedom (RDoF) without slippage. The capabilities were inspired by the unique interactions between two different innovative gears [the cross spherical gear (CS-gear) and monopole gear (MP-gear)] and the superimposition of those interactions by the CS-gearโs quadrature spherical tooth structure. One MP-gear constrains two of the three RDoF of the CS-gear.
The driving module which drives the MP-gear converts this โconstraintโ into a โdriveโ and drives the CS-gear with two RDoF. The CS-gear orthogonally superimposes the interactions caused by two MP-gears to achieve three RDoF driving forces.
