Torsion-resistant robot arm cable

Abstract

The invention provides a torsion-resistant robot arm cable which comprises a cable core arranged on the innermost layer, wherein a first buffer layer is arranged on the periphery of the cable core, aninner protective layer is arranged outside the first buffer layer, a second buffer layer is arranged on the periphery of the inner protective layer, and an outer protective layer is arranged outsidethe second buffer layer. The first buffer layer is wound on the periphery of the cable core and is used for reducing friction between the cable core and the inner protective layer; the second buffer layer is wound on the periphery of the inner protective layer and is used for reducing friction between the inner protective layer and the outer protective layer. According to the cable disclosed in the invention, the two aramid yarn winding layers play a role of a deceleration strip for bending and twisting of the whole cable, so that the torsional stress of the outer layer is gradually weakened when being transmitted to the cable core, and the purpose of torsion resistance of the cable is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a torsion-resistant robot arm cable. Background technique [0002] With the development of science and technology, industrial production tends to be more and more automated, and there are more and more cases of using robot arms for work. In the current industrial production, the cables used by robot arms are usually difficult to achieve the required torsion. The number of times, thus restricting the length of its work, can not meet the efficiency required for production, what's more, it will lead to accidents. [0003] Therefore, it is necessary to provide a torsion-resistant robot arm cable to solve the above technical problems. Contents of the invention [0004] Aiming at the above-mentioned technical problems in the related art, the present invention provides a torsion-resistant robot arm cable, which acts as a speed bump for the bending and torsion of the ent...
