Abstract With the continuous development of continuous improvement, constantly improve processing materials currently winch manufacturing technology and electronic control technology, winch has made great progress in the power, safety and energy saving etc.. At present, the winch is widely applied in the engineering machinery, construction machinery, mining machinery, shipping, offshore oil, deep-sea exploration and other fields. More and more long, the cable tension is more and more big, the effective protection of the winch speed control precision, the bottleneck in this research field.
Firstly, the development and history of the winch is described in detail. Secondly, analysis from the development status at home and abroad. In the overall mechanism design is introduced in detail introduces how to reduce the winch cable tension through friction between cable and winch drum wheel. Then, the corresponding theoretical calculations of the structure design, size calibration. Then, from the software part, using 3D software to draw the three-dimensional model design structure, together with the corresponding software and information. Finally, the paper on the winch to reduce tension structure design
Keywords:winch;drum;the friction;magnetic powder brake ;to release tension.
