ABSTRACT
The winch, is promotes or the hauling heavy item light small hoisting equipment with the reel winding steel wire. This design take the components fatigue theory and the linearity cumulative damage hypothesis as the rationale, the utilization statics general principle, analyzed and has solved in winch rate process some stress and the movement question, made every effort the optimization and the most reliable design winch reduction gear and the reel. In the most universal winch type of drive and in the structure foundation, utilizes the position sensing and the water level sensing technology, uses the PLC control, realized the traction winch to promote and to release the pump house according to the water level the automatic control and the hand control.
This article mainly introduced winch's historical development, the use, the composition and the principle of work; Traction winch's operating feature; Design general step; In the use exists question and corrective measure. In this traction winch's design process, to the reduction gear, the reel has carried on the analysis and the design emphatically. Has carried on the stress analysis, the intensity examination to the important part, according to its common failure mode, the influencing factor and the basic design request, has given the important part's stress analysis, the intensity and the rigidity design method.
