Abstract
The present disclosure provides a method, a system, a device and a medium for measuring gear tooth profile roughness. The method includes: obtaining design parameters of a target gear pair and test parameters of each tooth profile working point; fitting a measured surface profile and a theoretical tooth profile curve to obtain a surface structure curve; calculating a Hertzian contact width according to the design parameters and the test parameters for each tooth profile working point on the theoretical tooth profile curve, and determining an evaluation length of surface roughness according to the Hertzian contact width; filtering the surface structure curve by means of a filter with a set wavelength to obtain a surface roughness profile; and determining surface roughness parameters of each tooth profile working point in a working area according to the surface roughness profile for each evaluation length.
