| description | The time-varying meshing force caused by the transmission characteristics of non-circular gears has an important influence on gear drive wear. The elliptic gear pair of the key core components in combing machine is taken as the research object, and a calculation model of gear wear based on the time-varying meshing force is established by applying Hertz basic theory and Archard wear formula. The meshing stiffness of non-circular gears is solved by using the equivalent tooth number method, and the dynamic meshing force and wear of single tooth profile are analyzed. On this basis, the effects of order and eccentricity on dynamic meshing force and wear of elliptical gears are studied. The results show that the dynamic meshing force and wear of gear surfaces increase with the increase of eccentricity and order of elliptical gears. The time-varying meshing force changes at the junction of single and double tooth meshing zone. The tooth profile wear is close to zero near the pitch circle, and the wear is larger at the root and the crown. It is found that the root wear at the radial of the smallest section curve is significantly larger than that at the radial of the largest section curve. The results provide a theoretical basis for using the modification method to reduce the dynamic meshing force and wear, thus prolonging the life of gears. |
