Wuhan Shipbuilding 400,000 tons ore ship supporting anchor winch successfully passed ship inspection and inspection

On the basis of optimizing the cost of 319,000 tons of VLCC anchor winch, Wuhan Shipbuilding continued to carry out “design optimization, weight reduction and cost reduction” as the main content of the 400,000-ton series marine anchor winch in accordance with the first-class requirements of the international standard. Improve quality and efficiency.

From the aspects of structural design and material selection, the structure optimization of the anchoring machine is comprehensively carried out, and the product structure is optimized to achieve the optimal product structure; the work of “weight reduction and cost reduction” is carried out in terms of equipment weight and layout size, and passed in the design process. Three-dimensional design, simulation and other means to analyze the working conditions of the anchoring machine, gear life and contact frequency on different shafts, drum cylinder load and loading mode, spindle load and force fulcrum, etc., continuously optimize the wall thickness of the cylinder, Gear width and thickness dimensions, spindle material, base, single bracket, anchor sprocket material thickness, brake hinge arrangement and material of the parts.

At the same time, combined with the refinement requirements of the process, refine the processing steps, accurately calculate the processing time of each process, optimize the machining process to reduce the blank amount of parts, and carry out centralized procurement of similar parts, effectively reducing the procurement cost of parts and ensuring optimal product structure. The weight is reduced by 10%, and the goal of “weight reduction and cost reduction” of the anchoring machine is realized.
