Robot darg chain cable structure selection:

Flexibility can also be explained as flexibility, which is a property of an object relative to rigidity. Flexibility refers to a physical property in which an object undergoes deformation under force, and after the force is lost, the object itself cannot recover its original shape.

Hardness: In physics, the ability of a material to resist local pressure from hard objects on its surface is called hardness.

The local resistance ability of solids to external object invasion is an indicator for comparing the softness and hardness of various materials.

Soft cable is not  flexible cable

Selection of bending radius and flexible cable diameter for robot cables:

The bending radius, also known as the curvature radius, refers to the bending of a cable into a curve when it is in motion. The curve segment is replaced by a circular arc, and the radius of this circle is the bending radius.

The bending radius requirement varies depending on the outer sheath material:

PVC sheathed flexible wire have a bending radius greater than 7.5d, up to 6d; PUR sheathed flexible wire have a bending radius greater than 6d, up to 4d.

Once the structural design is completed, the installation space is determined. Under the premise of meeting electrical performance requirements, cables with smaller outer diameters should be selected as much as possible.

According to the different motion modes of the robot drag chain cable, it can be divided into:

● Robot body cable
● Joint robots and service robot cables
● Drag chain cable

Robot body cable: Experimental tests required for robot body cable:

● 3D torsion                    ● Two wheel bending              ● 2D torsion
● 90 degree bend           ● Vertical torsion                     ● Rapid bending
● Bending and rotation

 

Joint robot and service robot cable

 Experimental testing required for cables of articulated robots and service robots:

● Vertical torsion                   ● 90 degree bend                     ● Two wheel bending
● Rapid bending                    ● Bending and rotation

 

 

The experimental tests required for towing chain cables:

● Bending of drag chain
● 90 degree bend
● Two wheel bending
