Document Type and Number:
WIPO Patent Application WO/2019/114033
Kind Code:
A1
Abstract:
A thickness-variable transmission structure for a robot joint, comprising a housing (1), double gear rings (2, 4), and a planet carrier (8) which is fixed at the housing (1) by means of a crossed roller bearing (10); the planet is a double thickness-variable planetary gear (3) not having a sun gear; an input end is a pair of gears having a variable speed ratio or spiral bevel gears and is mounted on the housing (1) by means of a deep groove ball bearing; and the sun gear is removed, leaving a hollow shaft used for cable penetration and for relevant objects, such as shafts and wires, to pass through. The transmission structure is driven without a sun gear and has a simple and reliable structure, a transmission in which backlash is controllable, high rigidity, and a large range for the reduction ratio.
