Method for installing thermocouple for measuring temperature of end face of bearing in aero-engine

The invention belongs to the technical field of aero-engine inner bearing end face temperature measurement, and particularly relates to an aero-engine inner bearing end face temperature measurement thermocouple installation method. A test hole is machined in a bearing end face, and a temperature sensing head is manufactured on the periphery of a hot junction of a T-type fluorine-coated thermocouple through high-temperature soldering tin by means of a mold; and a processed hollow pipe is designed to install the temperature sensing head in the test hole, so that a lead of the T-shaped fluorine-coated thermocouple is fixed in a wall-attached manner by a spot welding process, installation is completed, and the temperature of the end surface of the bearing in the aero-engine is measured. 本申请属于航空发动机内轴承端面温度测量技术领域，具体涉及一种航空发动机内轴承端面温度测量热电偶安装方法，设计在轴承端面上加工测试孔，利用模具以高温焊锡在T型氟包热电偶的热结点外周制作感温头部，并设计以加工的空心管将感温头部安装在测试孔中，进而以点焊工艺对T型氟包热电偶的引线进行贴壁固定，完成安装，对航空发动机内轴承端面温度进行测量。
