The invention discloses a tooth profile detection mold, a measurement method, an evaluation standard and a coping method. The tooth profile detection mold comprises a tooth crest fitting edge, a firstmeasurement reference edge and a second measurement reference edge, a tooth profile measuring method and an evaluation standard are stipulated, the standard tooth
pitch is set to be P0 + / -T0, and when the interval G is smaller than or equal to T0, the tooth profile can not be ground; when the interval G is larger than T0, the tooth profile needs to be ground; when the distance P is out of tolerance slightly, the meshing surface of the detected rack attached to the lower portion of the tooth profile detection die is ground; when one tooth below is ground, the distance of the subsequent
tooth surface below is small and out of tolerance, and
grinding should be conducted downwards and smoothly; when the distance P is too large, the meshing surface of the detected rack attached to the upper portion of the tooth profile detection die is ground; and when the
upper tooth is ground and the distance of the subsequent
tooth surface at the upper part is too large and out of tolerance, the
grinding is upwards and smoothly carried out. The
pitch precision can be effectively improved, the problems of lifting load out-of-tolerance, sudden change and the like caused by
pitch out-of-tolerance and pitch sudden change are controlled, and the transmission precision is improved.
