在保养或维修压路机过程中,经常需要拆卸轴承座、轴承、轮毂及传动齿轮等零部件。由于普通两爪、三爪拉拔器不能完成此类拆卸工作,修理工通常采用錾子、撬杠等工具进行拆卸。若不能将其拆卸下来,就采用氧气烘烤或切割方法。这些拆卸方法不仅速度慢、成本高,甚至会将零件损坏。为了提高工作效率、节约修理费用,我们制作出1套专用拉拔器,使用效果良好。现介绍其结构、适用范围和使用方法。
In the process of maintenance or repair roller, often need to dismantle bearing parts, bearings, wheels and transmission gears and other components. As ordinary two-claw, three-claw puller can not complete such demolition work, the repairman usually prickly heat, crowbar and other tools for demolition. If it can not be removed, use oxygen baking or cutting method. These disassembly methods are not only slow, costly, and can even damage parts. In order to improve work efficiency, save the cost of repair, we have produced a set of special puller, the use of good results. Now introduce its structure, scope and methods of use.
