修理动力万向轴的工艺规程中规定,轴承部件的拆、装要采用铜冲子。钳工用冲子打击法兰体和万向接轴的叉形接头,将滚针轴承压离安装地点,这需要化费很多时间。这种拆卸方法生产率低,此外,还可能导致滚针轴承损坏。中亚铁路局克拉斯诺沃茨克机务段的合理化建议小组为了拆装动力万向轴研制成功了一种带风动液压系统的工作台(图1), Repair of universal shaft process regulations, the demolition of bearing components, installed to use copper punch. Locksmith punch with flange body and universal joint fork connector, the needle bearing pressure from the installation site, which takes a lot of time to spend. This method of disassembly is less productive and, in addition, can damage the needle roller bearings. The rationalization panel of the Central Asian Railway Administration Krasnvoerk locomotive depot succeeded in developing a table with pneumatic hydraulics for disassembly and assembly of universal shafts (Figure 1)
