Cable for internal contracting brake of high-flexibility anti-torsion rotor

Abstract

The invention relates to a cable for an internal contracting brake of a high-flexibility anti-torsion rotor. The invention aims to solve technical problems of how to conveniently install the cable for an internal contracting brake of a rotor, how to improve the signal stability of the cable for the internal contracting brake of the rotor, how to enable a signal line to be more flexible, and how to prolong the service life of the cable. The invention adopts the technical scheme that a cable for the internal contracting brake of the high-flexibility anti-torsion rotor comprises a power line, a signal line, filler, non-woven fabric, a shielding layer and a sheath; the power line comprises conductors of the power line and insulation layers of the power line from inside to outside in sequence; and the signal line comprises multi-core conductors of the signal line, insulation layers of the signal line, mylar foil, shielding layers of the signal line and outer sheaths of the signal line from inside to outside in sequence. The beneficial effects are that the service life of the cable is prolonged and the shielding performance of the cable is improved.

Description

technical field

[0001] The invention relates to a highly flexible and anti-twist robot brake cable. Background technique

[0002] The mechanical arm of the robot needs to be equipped with brakes at each joint. Its function is to keep the position of the mechanical arm unchanged when the robot stops working, and to protect the mechanical arm from colliding with objects around it when the power fails. Some components of the robot have low friction. When the drive stops working, they cannot bear the load. If the brake device is not used, once the power is turned off, the relevant parts of the robot will fall under the action of gravity. The braking device works according to the failure brake mode. Most of the braking device is placed at the drive input end of the system, and the transmission of its signal and action needs to be transmitted by cables. At present, the cables for robot brakes are generally divided into a power line and a signal line. Power cables are divided int...
