▎ 摘　　要

NOVELTY - The assembly has a main dimension joint part formed with an opening. A mounting hole is formed on a side wall of a main dimension joint part along radial direction. An outer screw thread is formed at the side wall of the main dimension joint part. A central axes of the mounting hole is formed in a central axial line of the main dimension joint. The mounting hole is formed in a surface of a connecting sleeve that is coated with graphene coating. A gasket is mounted between the end part of the connecting sleeve and the inner side narrow end of the limiting component. USE - Robot arm graphene joint assembly. ADVANTAGE - The assembly provides a joint assembly structure design, and arranges mounting hole position on the main dimension joint and graphene coating coated on the surface of the connecting sleeve, so that self-lubricating effect can be provided by rotating the pipeline under a joint displacement condition, thus improving work efficiency. The assembly can quickly processes the mounting hole and the outer screw thread in the main dimension joint and the connecting sleeve so as to ensure high assembling efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a robot arm graphene joint assembly.
