  • Check method of worm gears
    Patent number: 10816315
    Abstract: A check method of worm gears includes the following steps: identification of a real profile (PR) of a worm gear to be checked; scanning of the real profile (PR) in such a way to obtain a measured profile (PM), filtering of the measured profile (PM) with a low pass filter in such a way to obtain a primary profile (PP), filtering of the primary profile (PP) with a high pass filter in such a way to obtain a surface analysis profile (SA), calculation of three parameters (SAa; SAq; SAp) from said surface analysis profile (SA) and comparison of the three parameters (SAa; SAq; SAp) with preset threshold values (TSa; TSq; TSp) in such a way to reject the worm gear when at least one of the parameters exceeds the corresponding threshold value.

    Abstract: A check method of worm gears includes the following steps: identification of a real profile (PR) of a worm gear to be checked; scanning of the real profile (PR) in such a way to obtain a measured profile (PM), filtering of the measured profile (PM) with a low pass filter in such a way to obtain a primary profile (PP), filtering of the primary profile (PP) with a high pass filter in such a way to obtain a surface analysis profile (SA), calculation of three parameters (SA3; SAq; SAp) from said surface analysis profile (SA) and comparison of the three parameters (SA3; SAq; SAp) with preset threshold values (TSa; TSq; TSp) in such a way to reject the worm gear when at least one of the parameters exceeds the corresponding threshold value.
