Real-time measurement device for inner ring temperature of aircraft bearing

The invention discloses a real-time measurement device for the inner ring temperature of an aircraft bearing, belongs to the technical field of real-time measurement for the inner ring temperature ofthe aircraft bearing, and solves the problem that an existing bearing inner ring temperature measurement method is poor in measurement result or signal transmission stability. According to the invention, a driving motor drives a hollow shaft to rotate; at least two grooves are formed in the side wall of the hollow shaft, a temperature sensor is arranged in each groove, and the temperature sensorsare in contact with the inner ring of an aircraft bearing to be detected and used for detecting the temperature of the inner ring of the aircraft bearing to be detected; the hollow shaft is further sleeved with at least two conducting rings, and each conducting ring is connected with one temperature sensor through a wire; an electric brush is arranged outside the conducting ring, and the conducting ring is connected with a
