This paper describes a linear load-sensitive continuously variable transmission (CVT) with a spherical driving unit. This CVT mechanismconsists of a spherical drive, drive axis, motor housing, fixed bracket, and a linear sliding plate. It continuously changes the reduction ratio by changing the inclination angle of the active rotational axis. Additionally, this linear mechanism ensures load-sensitive functioning by changing the inclination of the active rotational axis in response to the load. We have developed a linear load-sensitive CVT and confirmed the effectiveness of the proposed mechanism.
