1、 - 1 - 摘 要 矿井提升机是沿井筒提升煤炭、矸石、升降人员、下放材料的大型机械设备。它是矿 山井下生产系统和地面工业广场相连接的枢纽,故要求具有很高的安全性,其成本和耗电 量也比较高。因此本次在矿井提升机选型设计中, 主要是根据所给参数确定矿井提升设 备,包括选择提升容器、钢丝绳、提升机、卷筒及校核提升能力,并经过多方面的技术经 济比较,结合矿井的具体条件,做到设计切合实际。保证提升机的选型及其运转两个方面都 是合理的, 最终确定具有经济安全合适的提升系统。本次在对主要部件主轴装置的设计计 算中,采用计算主轴上的正常载荷,根据其分别求出轴上的弯矩、扭矩及其相应的力,校核 轴危险断面的安全
2、系数及刚度。并对零部件轴、切向键、齿轮进行校核,充分保证了各部 件设计的合理性,尽可能地确定经济合理的最优设计方案。 关键词:矿井提升机 选型设计 主轴装置设计 - 2 - Abstract Mine Hoist is along the shaft upgrade coal, coal, movements, a large delegation of material mechanical equipment.
