An annular vibration reduction axle box with a temperature measurement hole belongs to the field of axle box devices of bogies of railway vehicles and comprises an axle bearing, an axle box positioning and temperature measurement heat conduction sheath and a vibration reduction rubber ring, the axle box positioning and temperature measurement heat conduction sheath is coaxially and fixedly connected with an outer ring of the axle bearing, the inner ring of the axle bearing is coaxially pressed and fixedly connected to the axle and the upper part of the damping rubber ring, and the central connecting line of a shell socket for positioning the temperature sensor and a rubber ring blind hole socket of the damping rubber ring forms an angle of 60 degrees relative to the horizontal plane. The axle box is internally arranged in the inner sides of the wheel sets, so that the damage risk caused when the axle box is externally arranged is reduced, the overall structural size and the turning radius of the bogie are effectively reduced, and the curve passing capacity of the bogie is further improved; and according to the annular vibration reduction axle box, the semi-annular shell and the semi-annular clamp type axle box hanging base are buckled into a complete circular ring structure in a bolt connection split type clamp mode, installation, disassembly and maintenance are convenient, and meanwhile the adverse effect of welding deformation is avoided.

    带有测温孔的环形减振轴箱属于轨道车辆转向架轴箱装置领域,该轴箱包括车轴轴承、轴箱定位及测温导热护套和减振橡胶环,轴箱定位及测温导热护套与车轴轴承的外圈同轴固连,车轴轴承的内圈同轴压装固连于车轴和减振橡胶环的上部均设有定位温度传感器的壳体插口和减振橡胶环的橡胶环盲孔插口二者中心连线与水平面呈60°角。本发明的轴箱内置于轮对内侧减少了轴箱外置时的受损风险,有效降低了转向架整体的结构尺寸和回转半径,使该转向架的曲线通过能力获得进一步的提升;该环形减振轴箱通过其半环形外壳采用螺栓连接的分体式卡箍形式与半环卡箍式轴箱吊座扣合成为完整的圆环结构,既便于安装和拆卸维修,同时也免除了焊接变形的不利影响。
