Slotting Processing And Meshing Performance Analysis Of Orthogonal Face Gear

Face gear transmission is a new structure that using the cylindrical gear to cooperate with face-gears.Can be used to transfer power between shafts Angle transmission.In this paper,According to orthogonal face gear slotting machining to establish the three-dimensional modeling,error analysis,process simulation and its meshing performance of four aspects has carried on the thorough exploration and research.According to the orthogonal face gear slotting machining principle to establish a relative coordinate system.And then by the conjugate surface into constructing principle of the mathematical model of the orthogonal face gear tooth surface,At last to determine the arrival of the tooth root cutting radius,tip radius and the selection of its effective teeth tooth.Then use Pro/E software to establish three-dimensional model of face gear.Tooth surface equations are built at the same time,on the basis of considering the pressure Angle error of gear shaper cutter and the transmission error,and the error model is established.Opposite the solution through the analysis to determine the error of two kinds of gear pressure Angle,the tooth profile of gear tooth and tooth thickness effects.In view of the face gear slot machining simulation not accuracy,in WFL M35 car milling compound machine tool for processing platform,on the basis of using virtual machining software VERICUT across the gear slotting machining process simulation.In the simulation process can not only visual image of the observed surface gear slotting machining process,and the analysis of complete work pieces,also can be observed clearly face gear tooth surface shape and the tooth addendum to pointy and tooth root cutting phenomenon.To verify the face gear generatingprinciple and the accuracy of gear shaping process,for the further design of orthogonal face gear processing and provided the powerful basis.Considering the particularity of face gear slotting machining,the number of teeth on the gear shaper cutter are much more than the cylindrical gear 1-3,According to face gear and spur gear on the tooth surface meshing points have the position of the public and the normal vector,cylindrical gear is deduced and the face gear meshing track equation,and the contact path on the surface of the gear visualization simulation,by changing the cylindrical gear wheel teeth,calculate the trajectory of the contact position.At the same time,using the ADAMS software across the meshing gear transmission system is emulated,by changing the cylindrical gear teeth,according to the results of simulation and data analysis of the cylindrical gear with tooth number difference across the gear transmission error of gear shaper cutter and the influence of acceleration,so as to determine the different cylindrical gear across the effects caused by the gear mesh performance.
