This paper seeks to address a gap in technology in belt pulley systems by applying kinematic metastructures (Hoberman rings) to develop mechanisms for variable transmission. Here, we describe a design process to enable antagonistic expansion and contraction in dual Hoberman ring belt pulleys. Our design process considers the complex aspects of geometry, component size, tolerances, and wireless motoric actuation.

摘要

This paper seeks to address a gap in technology in belt pulley systems by applying kinematic metastructures (Hoberman rings) to develop mechanisms for variable transmission. Here, we describe a design process to enable antagonistic expansion and contraction in dual Hoberman ring belt pulleys. Our design process considers the complex aspects of geometry, component size, tolerances, and wireless motoric actuation.
