AI Technical Summary
In existing trackless servo motor tensioning equipment, the wire rope is prone to swinging during the winding and unwinding process, and material fatigue can lead to breakage, affecting the stability and safety of the equipment.
A power belt is used instead of a steel wire rope, and a stable vertical movement trajectory is provided through the cooperation of a guide rope and a guide hole. Combined with a take-up pulley and a reversing pulley, the stability and accuracy of the rope movement trajectory are ensured.
It improves the stability and safety of the mechanism's operation, reduces the risk of material fatigue fracture, and ensures the accuracy and reliability of the tensile action.
