Multi-Joint Bionic Mechanism Based on Non-Circular Gear Drive [PDF]

Biomimetics, 2023
Aiming at the nonlinear expansion/contraction drive problem between different cables in multi-joint cable drive mechanisms, a mechanical drive method based on a non-circular gear drive was proposed, which could replace the servo-sensing control system ...

The mathematical model of non-circular crossed-axis gear [PDF]

Advances in Mechanical Engineering, 2023
Non-circular crossed gear can be regarded as the general form of the single stage gear, which can be converted into hypoid gearing, non-circular bevel gearing, non-circular external gearing, and non-circular internal gearing with specific parameters.
