变节距排缆绞车机构设计与研究

摘要在工业中,绞车是一种比较常见的工程机械。被广泛的应用于林业、矿业、建筑、水利工程和海洋诸多领域,针对绞车在一些场合速度会受到干扰的问题以及为了减小排缆角,并且使排缆机构能够更好的适应不同直径的缆绳,本论文提出了一种绞车方案,对变节距排缆绞车机构进行了深入的研究,具有重要的实际意义和理论价值。52353

论文首先对绞车的发展和历史做了详细的阐述。其次从国内外的发展状况进行剖析。在整体机构设计中详细介绍了绞车如何通过丝杠排缆结构进行变节距排缆的总体方案。然后，对该设计结构进行相应的理论计算。论文随后从软件部分着手，用三维软件画出设计结构的立体模型，并附有相应的软件和图文资料。最后，论文提出变节距排缆机构设计的完善和改进，并对该课题的发展作了展望。

Abstract In the industry，winch is a common engineering machinery。it is widely used in mining，construction，forestry, water conservancy engineering and marine areas，the winch interference problem on a number of occasions in order to reduce speed and cable arrangement angle，and make the fairleader can better adapt to different cables ,this paper proposes a scheme for variable pitch winch，cable arrangement the winch mechanism are studied，with the actual significance and important theoretical value.

Firstly, on the development and history of the winch to do a detailed elaboration. Second, from the development of domestic and analyze. In the overall institutional design are described in detail how the winch variable pitch screw for the cable row overall program. Then, the design of the structure of the corresponding theoretical calculations. Papers then proceed from the software part, three-dimensional design software to draw three-dimensional model of the structure, together with the corresponding software and graphic information. Finally, the paper presents variable pitch row cable institutions to refine and improve the design and development of the topic discussed.

Keywords：Winch，Variable Pitch Cable , Screw
