The invention discloses an in-service wind driven generator variable pitch bearing raceway detection system and a use method thereof, and belongs to the technical field of wind power generation detection. Comprising an ultrasonic phased array detector, an acoustic transmission wedge block, a phased array probe and a clamp, the acoustic transmission wedge block and the phased array probe are fixed on the clamp, and the acoustic transmission wedge block is located at the front end of the phased array probe; the front end of the acoustic transmission wedge block is provided with an inclined angle which is in profile modeling with variable pitch bearing gear teeth; and the phased array probe is connected with the ultrasonic phased array detector through a connecting line. According to the invention, the roller path of the variable pitch bearing, which is easy to have defects, can be detected, the operation is simple and convenient, and a reliable guarantee is provided for safe and stable operation of a wind gener
