The invention discloses a bearing temperature measuring device for an elevator traction machine. The traction machine comprises a traction wheel and a machine base. A bearing is installed in the traction wheel. A square groove is formed in the machine base. A thermistor is installed in the square groove. One side of the thermistor makes tight contact with the bearing and the other side of the thermistor is connected with an elevator control module through a circuit. In the operation process of the traction machine, if it is monitored that the temperature of the bearing is abnormal, a power source is cut off instantly, an elevator cannot operate, maintenance personnel can perform an overhaul in time, and potential safety hazards of the elevator in operation are avoided.
