【摘要】 在煤矿生产的过程中,矿用绞车时是必备的基础工具,矿用绞车的安全运行关系到整个煤矿的运输环节与生产情况。现如今,煤矿绞车朝着标准化、高效节能化、以及轻量化方向前进。尤其是针对目前很多绞车在煤矿场地较小的情况下,或者地理位置受限的情况下,轻量化和结构紧凑的绞车将更为实用。所以结合目前的需求,本论文主要是在董家河煤矿西翼坡头场地作为实际的考察,设计了实用的整体绞车方案,并且改变了以往传统的矿用绞车结构,并通过计算与仿真验证的方式方法设计验证出占地面积小、质量减小的煤矿绞车。首先,结合目前绞车使用现状以及目前生产的需求分析了目前绞车的结构性能,同时实地考察董家河煤款西翼坡头场地,根据需求参数设计减速器的方案。确定该减速器两级传动方式,确定各齿轮齿数、模数等齿轮参数。确定其内部电机、行星架、滚筒等联接方式,确保其使用应力、强度满足需求。在确定减速器方案之后,将整体绞车结构做出新设计,抛弃了以往减速器和电机在外面的情况,此绞车将电机与减速器放置在滚筒的内部,通过行星轮的外齿圈带动滚筒的外部做旋转,起到提拉矿物的作用。以往此结构没有用在矿用绞车上的先例,在整体结构上对绞车绘制出二维图,再画出整体的三维制图。通过ANSYS来分析滚筒、行星齿轮各部分、承重轴等,确定整个的设计可以作为董家河煤矿西翼坡头场地的矿用绞车来进行使用。通过尺寸优化的方法设立优化条件来对整体的绞车进一步进行轻量化的优化,通过在行星减速器、滚筒等部分做尺寸优化,行星架做更改材料的轻量化改变。通过再次应力分析对比,给出轻量化之后各参数。对轻量化前后的滚筒做模态分析,确保其不会发生共振。为保证整体的使用性能,改进其以往使用的后置式盘式制动器,通过改进成为结构紧凑式盘式制动器,做出结构调整,达到整体最优化。本论文共有图58个,表24个,参考文献95篇。更多还原

【Abstract】 First of all,with reference to the current situation in the domestic and foreign fields and the current requirements for winches in coal mine production,the structural performance of the current winches was analyzed,and at the same time,the site of the west wing of Dongjiahe Coal was inspected,and the reducer was designed according to the required parameters.Plan.Determine the two-stage transmission mode of the reducer.Determine its internal motor,planet carrier,roller and other connection methods to ensure that its use stress and strength meet the requirements.After determining the reducer plan,a new design was made for the overall winch structure,abandoning the previous situation that the reducer and motor were outside.This winch puts the motor and the reducer inside the drum,and drives the drum through the outer ring gear of the planetary gear.The outer part of the machine rotates to lift the minerals.In the past,there is no precedent for this structure to be used in mining winches.A two-dimensional drawing of the winch is drawn on the overall structure,and then the overall three-dimensional drawing is drawn.Through ANSYS to analyze the drum,planetary gear parts,load-bearing shaft,etc.,it is determined that the entire design can be used as a mine winch for the west wing Potou site of Dongjiahe Coal Mine.The overall winch is further optimized for light weight by setting up optimization conditions through the method of size optimization.By optimizing the size of the planetary reducer,drum and other parts,the planet carrier is made lighter by changing the material.Through the stress analysis and comparison again,the parameters after weight reduction are given.Perform modal analysis on the rollers before and after the weight reduction to ensure that they will not resonate.In order to ensure the overall performance,the rear-mounted disc brake used in the past was improved,and the structure was adjusted to a compact disc brake to achieve the overall optimization.This paper has 58 figures,24 tables and 95 references.更多还原
