Abstract

According to the design theory of helical involute gear and less-teeth gear,the 3D model of less-teeth gear pair was built with the selected each parameter.Due to contact finite element analysis on this gear pair,its contact area and contact stress during transmission process was obtained.Also by comparing two methods for the calculation of contact strength,validity of the lower-Bound points as calculate points was initially verified.The results proved that the method can provide a reference for gear pair profile modification and establishment of tooth contact strength formula.
