| description | In order to construct an accurate model of asymmetric involute modified helical gears and analyze the influence of pressure angles on its contact stress, based on the gear meshing principle and the secondary development of SolidWorks in C#, a mathematical model and an accurate physical model for developing an asymmetric involute modified helical gear from a rack tool are established. At the same time, the finite element method is used to analyze the tooth surface contact stress, and it is compared with the tooth surface contact stress of the symmetrical modified helical gear calculated by the traditional formula method. The study shows that when the pressure angle on one side of the tooth surface is the same, the tooth surface contact stress of the asymmetric involute modified helical gear is very close to that of the symmetric modified helical gear, and the increase and decrease trends of contact stress with changes in the pressure angle are basically the same. It shows that the change of the non-working side tooth surface pressure angle has no obvious influence on the working side tooth surface contact stress. Therefore, the traditional formula method used to calculate the tooth surface contact stress of symmetrical modified helical gears can be used to approximate the tooth surface contact stress of asymmetric involute modified helical gears. This method provides reference for the design of asymmetric involute modified helical gears. |
