The present invention relates to a heat detecting device of a train wheel bearing, which comprises: a thermoelectric element which is in contact with a train wheel bearing to convert heat generated in the wheel bearing to electric energy; a capacitor which is electrically connected to the thermoelectric element to store the electric energy generated in the thermoelectric element; and a heat warning unit which is supplied with the electric energy from the capacitor to display a change in a temperature of the wheel bearing to the outside.

    본 발명은 차축베어링 발열감지장치에 관한 것으로서, 철도차량의 차축베어링에 접촉되어 차축베어링에서 발생되는 열을 전기에너지로 변환하는 열전소자와; 상기 열전소자와 전기적으로 연결되어 상기 열전소자에서 생성된 전기에너지를 저장하는 캐패시터와; 상기 캐패시터로부터 전기에너지를 공급받아 상기 차축베어링의 온도변화를 외부로 표시하는 발열경보부를 포함하는 것을 특징으로 한다.
