Method for measuring temperature of outer ring of bearing at end part of transmission shaft of accessory casing of aero-engine

The invention belongs to the technical field of aero-engine accessory casing transmission shaft end bearing outer ring temperature measurement, and particularly relates to an aero-engine accessory casing transmission shaft end bearing outer ring temperature measurement method. And the stud, the first stainless steel pipe and the second stainless steel pipe are designed, the armored hot couple is reliably fixed on the outer side of the bearing outer ring for temperature measurement, reliable sealing can be carried out, and the defects of an existing wall surface temperature installation method are overcome. 本申请属于航空发动机附件机匣传动轴端部轴承外环测温技术领域，具体涉及一种航空发动机附件机匣传动轴端部轴承外环测温方法，其设计在轴承外环外侧加工温度测试孔、在轴承安装座上加工螺纹孔，以及设计螺柱、第一不锈钢管、第二不锈钢管，将铠装热点偶可靠的固定在轴承外环外侧，进行温度测量，且能够进行可靠密封，克服现有壁面温度安装法的缺陷。
