JHMB-14回柱绞车的设计毕业论文.doc

I摘要在国内,平均每年需求各种不同规格的矿用回柱小绞车数万台,因此,降低成本和提高安全性对回柱绞车的开发具有重要意义。在本次设计中,把两级齿轮分别装在电动机和卷筒的两侧,使结构紧凑,减少底座材料的使用降低了成本把蜗轮蜗杆传动原理知识运用到设计中,利用蜗轮蜗杆副具有较大的传动比这样可以实现卷筒的希望速度,可以避免由于卷筒反转造成的意外损失由于该机器用于矿场上所以必须具有一定的防爆能力,所以选用防爆电动机带提原来的鼠笼式电动机选用制动装置使得绞车在需要或者紧急的情况下停止转动。关键词绞车滚筒减速器制动器IIAbstractInthedomestic,everyyearweneedeverykindofdifferentspecificationofthewinchcountabouttenthousandthsetsonaverage,therefore,decliningthecostwillbeveryimportanttothemachinedevelopment.Inthisdesign,wemakethetoothbesidesoftheelectricmotorandthedrum.Usethedesignmakestructurecompactionanddeclinethematerialofthebase,sothatwecandeclinethecostwemaketheknowledgeofthegearofthewormandgearintothedesign,usethegearofthewormandgearhavelargeproportionoftransmission,becauseofit,wecanobtaintheproportionoftransmissionaboutwoundroolwehopeintheoreyardweoftenusethemachine,so,itmusthavetheabilitytopreventexplosion,therefore,wemustchosetheexplosionpreventionelectricmotortoreplacethecagemotortheuseofthearrestinggeartomakethewinchstopinthetimeofwhenyouwantitorintheemergencytime..Keywordswinchrollerretarderarrester徐州工程学院毕业设计论文I目录1绪论...........................................................................................................................................11.1课题背景............................................................................................................................11.1.1绞车的分类.................................................................................................................11.1.2绞车的特点和性能要求.............................................................................................11.1.3绞车功能与结构.........................................................................................................21.2国内外矿用小绞车的发展概况........................................................................................31.2.1概述................................................................................................................................31.2.2国内外水平对比.........................................................................................................31.2.3结构型式.....................................................................................................................51.2.4发展趋势.....................................................................................................................51.2.5采取措施.....................................................................................................................62回柱绞车主要性能参数的确定...............................................................................................82.1钢绳拉力............................................................................................................................82.2钢绳绳速............................................................................................................................82.3电动机额定功率................................................................................................................82.4钢绳型式和直径的确定....................................................................................................92.5卷筒直径的确定...............................................................................................................123各类零件的设计和强度计算.................................................................................................133.1引言..................................................................................................................................133.2技术规格与参数..............................................................................................................133.3电机的计算和选取..........................................................................................................143.4计算各轴的运动和动力参数..........................................................................................153.5蜗轮蜗杆的设计和计算..................................................................................................163.6齿轮的计算和强度校核..................................................................................................203.6.1一级齿轮的设计与计算...........................................................................................203.6.2二级齿轮的设计与计算...........................................................................................253.7各轴的设计和计算..........................................................................................................303.7.1蜗杆轴分析与强度校核...........................................................................................303.7.2蜗轮轴的分析和强度校核.......................................................................................333.7.3齿轮轴的分析与强度校核...................................................................................353.7.4滚筒轴分析与强度计算...........................................................................................383.8轴承的选用和强度的校验..............................................................................................40徐州工程学院毕业设计论文II3.9联轴器的选择和计算....................................................................................................463.10制动器的选择和
