为了拆卸内燃机车牵引电动机电枢轴圆锥面上的齿轮,联结结构规定采用注油无刨紧固联结法,以消除输出轴表面和轴承的损坏。然而,这种方法在内燃机车维修工作中由于拆卸工艺参数不稳定,还不能广泛地被采用。在使用过程中,便导致过载和设备过早的损坏。进行了用注油压力膨胀法拆卸牵引电动机齿轮的试验研究,并把工艺设备的结构完善化。第一次实验表明:当按照计算油压力拆卸时,三分之一以上的齿轮拆不下来,因为润滑油渗不到接触区域内。通过对油压力值、结合表面的情况以及联结时所用油压系统的记载分 In order to disassemble the gear on the armature conical surface of the traction motor of the diesel locomotive, the joint structure stipulates the oil-free planing and fastening method to eliminate the damage of the output shaft surface and the bearing. However, this method can not be widely adopted in diesel locomotive maintenance work due to the instability of disassembly process parameters. During use, it causes overload and premature damage to the equipment. The experimental research on disassembling the traction motor gear with oil pressure expansion method was carried out and the structure of the process equipment was improved. The first experiment showed that when it was disassembled according to the calculation of oil pressure, more than a third of the gears could not be disassembled because the lubricating oil did not seep into the contact area. Through the oil pressure value, the combination of the surface conditions and the oil pressure system used when linked points
