内燃机车牵引电动机损坏的原因之一是由于电枢铁芯最外面的叠片振荡而引起的绝缘击穿。为了提高叠片的刚性。鄂木斯克铁路运输工程学院研究成功了一种用焊丝进行铁芯叠片接触焊的工艺,见图1。根据文献资料和初步实验的分析结果,对如下焊接过程的控制参数(如影响焊接接头几何尺寸及其强度指标的参数)作了研究:焊接变压器次级绕组电压;焊接时间和电极夹持器传动装置的风缸压力(该压力表示夹持器的夹紧力)。填充焊丝的直径以及 One of the causes of damage to the traction motor of a diesel locomotive is the dielectric breakdown caused by the lamination of the outermost laminations of the armature core. In order to improve the stiffness of lamination. Omsk Railway Engineering Institute of successful research with a wire core lamination contact welding process, shown in Figure 1. According to the literature and preliminary experimental results, the following control parameters of the welding process (such as the parameters affecting the welding joint geometry and its strength index) were studied: the secondary winding voltage of the welding transformer; the welding time and the electrode holder drive The device’s cylinder pressure, which represents the clamping force of the gripper. Fill the wire diameter as well
