The invention relates to a gear failure part feature reconstruction method based on RE and belongs to the technical field of reverse engineering and the field of gear remanufacturing. The method comprises the following steps of 1, carrying out linear cutting treatment on a failure gear to remove a residual stress layer of the failure gear, and coloring the failure gear; 2, scanning surface characteristics of the failure gear to obtain point cloud data; 3, abnormal point removal, noise reduction, packaging, simplification and hole filling are carried out on the point cloud data on the surface of the failure gear; 4, reconstructing the failure gear based on a reverse engineering principle; and 5, analyzing the precision of the reconstruction model according to the adjacent teeth of the defect part. According to the method, a precision problem of failure part model reconstruction in gear remanufacturing at the present stage is solved, an effective method is provided for feature reconstruction of the gear failure part, a problem that the precision of the gear failure part model reconstruction is low is solved, and a foundation is laid for improving the gear remanufacturing and repairing quality.
