Abstract

The invention discloses a torsion flexible cable for a robot mechanical arm. The flexible cable comprises a cable core, and a first belting layer made of polytetrafluoroethylene, a total metal shielding layer made of copper-tantalum alloy wires, a second belting layer made of polytetrafluoroethylene and an outer sheath made of a modified polytetrafluoroethylene material which are sequentially coated outside the cable core from inside to outside, wherein the modified polytetrafluoroethylene material takes polytetrafluoroethylene as a base material, and the main addition is polyether block amide; and the cable core comprises a plurality of reinforcing cores and a plurality of three-wire core assemblies. The invention provides a torsion flexible cable for a robot mechanical arm, which is highin tensile strength, low in friction coefficient, high in torsion resistance and high in wear resistance, and aims at solving the problem that a cable in the prior art is easy to deform and break ina mechanical arm or drag chain system which moves at a high speed, continuously bends and twists and is pulled by tension.

Description
