一、概述火车热轴红外探测器是一种测量火车轴箱温度的自动检测装置。用它来代替目前的人工检测在铁路运输中是很有意义的。它可以减轻劳动强度,解放劳动力,提高生产效率及车辆周转率。它为铁路运输现代化提供了一种初步的检车工具,以适应我国工农业飞速发展的需要。目前我国火车货车的轴承是一种轴瓦结构。即一块软合金轴瓦与钢性轴承滑动摩擦,中间加油润滑。在火车运行过程中,由于摩擦生热就会辐射出红外线。这种红外辐射的能量在正常运行情况下是较微弱的因此时轴温较低。但当磨擦过度时,轴温骤然升高或发生切轴危
First, an overview Train thermal axis infrared detector is a measurement of the temperature of the train axle box automatic detection device. Use it instead of the current manual inspection in the railway transport is of great significance. It can reduce labor intensity, liberate the labor force, improve production efficiency and vehicle turnover. It provided an initial check-up tool for the modernization of railway transportation in order to meet the needs of the rapid development of our country's agriculture and industry. At present, China's train truck bearing is a bearing structure. That is, a soft alloy bearing pads and steel bearings sliding friction, the middle of lubrication. In the process of running the train, it will radiate infrared ray due to friction heat. The energy of this infrared radiation is weaker under normal operating conditions and thus the temperature at the axis is lower. However, when the friction is excessive, the temperature of the shaft suddenly rises or the danger of cutting the shaft occurs
