提供全套毕业论文，各专业都有摘 要转向架圆锥滚动轴承压装机是用于铁路车辆滚动轴承压装的专用设备，适用于铁路车辆新造及检修时压装 SKF197726、352226 型轴承。广泛应用于各车辆厂、车辆段、车辆大修厂及煤矿铁路运输单位。本次设计是根据 25t 轴重列车的资料和其工作现场情况，设计出达到压装要求的轴承压装机。压装机工作过程直接影响转向架运行情况，车轴是转向架的重要零件，为提高行车速度，进一步提高列车车辆的运营能力和效率，增强与航空、公路、水运的竞争力，必须要确保轮对轴承压装质量，提高行车的安全性与平稳性。假如压装过程不合理，产生错误，将会造成严重后果，车辆运行时噪声过大，起动加速度，制动减速度减小，甚至会发生轴温过热切轴等重大事故。为达到要求，必须使压装机输出适当且足够大的压装力，提高轴承与轴颈的配合精度。因为压装机工作过程输出压力大，速度慢，压装机采纳液压传动系统。压装部分是压装机的最重要组成部分，本文主要是针对圆锥滚动轴承压装机的压装部分的机械结构进行设计。关键词： 转向架；滚动轴承；压装；机械AbstractBogie taper rolling bearing push mounting machine is the appropriation equipment for railcar rolling bearing mounting. It is widely used for mounting the SKF197726 and 352226 moulds bearings in making and overhauling railcar, and widely used in vehicle factories, vehicle sections, vehicle overhauling factories and mine railcar companies etc. In this thesis, it is aimed to design a push mounting machine fulfilling the push mounting requirement, based on data of 25t axle load railcar and fieldwork. The process of the rolling bearing push mounting is of great importance to the bogie. To get higher speed, and become more competitive with aqueduct, air and highway transport. If mistakes be made in the push mounting process, it may result in big trouble, the railcar will make over volume noise in running period, the starting and breaking acceleration will reduce to a low and dangerous level. To up to the scratch, the machine has t...
