Abstract
A thickened robot joint transmission structure comprises a shell, dual gear rings and a planet carrier, wherein the planet carrier is fixed to the shell through a crossed roller bearing. Planet gears are dual thickened planet gears free of a sun gear. The input ends are a pair of gears or spiral bevel gears with a variable velocity ratio and are fixed to the shell through deep groove ball bearings. The dual thickened planet gears serve as a hollow for a cable, a related shaft or a line object to pass through after the sun gear is removed.
