Wear-resisting wire dividing wheel with test hole

The utility model discloses a wear-resisting wire dividing wheel with a test hole. The wheel comprises a wheel body which is of a wheel hub-shaped circular structure. A wire dividing groove is arranged in the circumference of the outer surface of the wheel body. Wear-resisting ceramics are sprayed on the wire dividing groove. An axial hole is arranged in the center of the wheel body. The test hole is arranged in a wheel face in the diameter direction of the wheel body. According to the utility model, an integrated design is adopted, the test hole used for a near connection switch is arranged in the wire dividing wheel, and the wear-resisting ceramics are sprayed on the wire dividing groove, so wear resistance of the wire dividing wheel and precision of a detection signal are improved, and service lifetime of the wire dividing wheel is greatly extended.
