Design of Gear Parameter Measurement and Evaluation System Based on Machine Vision
Aiming at the problems of inconvenient measurement,low efficiency and weak human-computer interaction in tradition-al gear parameter detection,a gear parameter detection and evaluation system based on machine vision was designed by using virtual in-strument technology,image processing technology and machine vision technology with LabVIEW as the development platform.The system has the functions,such as gear images collection,image processing,system calibration,shaft hole center detection and gear parameter detection and evaluation.lt can be used to measure and evaluate gear addendum circle,tooth root circle,single pitch deviationfpt,total pitch deviation Fpand common normal length deviation.The 0-level standard gauge block was used to calibrate the system,and the de-signed system was tested and compared.The test results were compared with the design theoretical values of the gear to evaluate the ac-curacy of the system.The results show that the detection and evaluation system has a friendly interface,easy expansion,high efficiency and convenient operation,and can automatically save and playback the collected data and visually evaluate the gear parameters.
