[0026] The upper surface of the testing platform 2 is fixedly connected with a collecting box 13 and an air pump 14 connected to the collecting box 13, and the inner wall of the collecting box 13 is respectively fixedly connected with a filter screen plate 15 and a magnetic rod 16, and the upper surface of the testing platform 2 is fixedly connected with an air collecting plate 17 connected to the air suction end of the air pump 14, and the inner wall of the air collecting plate 17 is connected to a plurality of air suction hoods 18, which can absorb the waste generated by the friction of the gear 11 to be tested during the testing process, prevent the gear waste from affecting the test results, and at the same time prevent the waste from being adsorbed on the surface of the gear again, reducing the mechanical wear caused by the waste;

[0027] A through hole is opened on the inner wall of the testing platform 2, and a rotating motor 19 is fixedly connected to the hole wall of the through hole.
