摇杆是传递鞲鞴推力的重要部件,受力情况复杂,如强度不足,就会发生折断,造成行车事故。 1984年5月2日,我段曾发生了前进型1273号机车右侧摇杆中部折断的事故,由于乘务员处理得当,才未造成重大损失。该机车摇杆折断,是在距小端孔中心1695毫米处,断面呈明显的裂纹产生区、发展区和断裂区。经分析,主要原因是探伤工责任心不强,工作不细,探伤时未能探出该处的裂纹,导致机车投入运用十一天后,即发生摇杆折断的事故。从摇杆本身的强度来看,由于偏低,这也可能是造成折断的一个因素。本文就摇杆强度问题谈谈本人的体会,供大家参考。为了校核摇杆的强度,首先分析一下摇
Rocker is an important part of the transmission 鞲 鞴 thrust, the force situation is complex, such as lack of strength, it will break, resulting in traffic accidents. On May 2, 1984, an accident occurred in the middle of the right rocking bar of the forward type 1273 locomotive in our paragraph. As the flight crew handled it properly, no major loss was caused. The locomotive rocker break, is in the small end hole center 1695 millimeters, the section was obvious crack generation zone, development zone and fracture zone. After analysis, the main reason is the weakness of the inspector, the work is not fine, the test failed to probe the crack, causing the locomotive put into use after eleven days, that is, rocker broken accident. From the strength of the rocker itself, due to low, this may also be a factor in causing a break. This article talks about the strength of rocker my experience for your reference. In order to check the strength of the rocker, first analyze the shake
