... A two-tooth difference swing-rod movable teeth transmission is a type of transmission evolved from a planetary transmission with small tooth differences, which has the advantages of a large speed ratio and strong bearing capacity. It can meet the low-speed, large-torque and highprecision requirements of mechanical transmission systems for the aiming and tracking performance of large optical instruments such as astronomical telescopes and solar energy tracking systems [1,2]. There are extensive prospects of application for this drive in the transmission field. ...
