本科毕业设计(论文) 题目:机车轮对轴承压装机液压系统设计 系别机电信息系 专业机械设计制造及其自动化 班级 学号 导师 2013年05月 机车轮对轴承压装机液压系统设计 摘要 轮对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轴承,被广泛应用于各个路局车辆维修、车辆制造厂生产,其对国民生产有着重要的意义。现如今的铁路速度越来越快,对轴承的要求越来越高,而轴承的压装是铁路安全的关键。为了达到使原有轮对轴承压装机能够获得更可靠更优秀的性能,本次设计主要针对轮对轴承压装机进行设计,通过对轮对轴承压装机原有技术的改进(主要是液压系统的改进),实现对轮对轴承压装机轴承的准确压装,以便更进一步提高行车的安全性与平稳性。 关键词: 滚动轴承;压装;液压系统 全套图纸,加153893706 Loader hydraulic system design of otive wheelset bearing pressure Abstract Wheel axle pressure installed special equipment for railway vehicles pressing the bearing press-fit bearings suitable for new-building and maintenance of railway vehicles. Widely used in various railway administrations of its gross national product of great significance . It is widely used , and widely used in vehicle factories, vehicle sections, vehicle overhauling factories and mine panies etc. In this thesis, it is aimed to design and improve the original while axle pressure installed (improve the original design of hydraulic pressure system)to get a new device has reliable and excellent property. To get a accurate push mounting with the wheel axle pressure installed, in order to further increase the security and smooth. Keywords: Taper rolling bearing;Push mounting;Hydraulic pressure system
