Research On Special Machining Process Of The Straight Teeth Face Gear

The straight teeth face gear is a kind of planar gear which is meshed with spur gear,with its high coincidence degree,calm transmission,low noise and efficient torque diversion characteristics makes straight teeth face gear be widely used in numerous transmission fields in low and high speed,and in light and heavy load.Since the tooth surface of straight teeth face gear is much more sophisticated,and its geometry is a complex spatial curved surface instead of traditional involute flank or other common tooth surfaces,in order to solve the traditional generating method problems of long period,high cost and not suitable for batch production in the process of machining straight teeth face gear and the phenomenon of low precision of batch production in the process of machining straight teeth face gear by traditional forming method.In this paper,a rapid manufacturing process of straight teeth face gear based on electrochemical machining technology is proposed to achieve the mass rapid manufacturing of straight teeth face gear under the premise of quality assurance.Firstly,the tooth surface model of the straight tooth is numerically modeled by using the tooth surface modeling method of the straight tooth surface gear.The three-dimensional model of the tooth surface of the straight tooth is used for the electrolytic processing and the corresponding straight According to the three-dimensional model structure of the straight tooth gear,according to the injection mold design method with the active forming parts,the corresponding straightening method is designed according to the design method of the injection mold of the active forming parts.In order to solve the technical defects in the traditional production of the " The three-dimensional model of the tooth-tooth gear was established,and the FDM rapid prototyping technology was used to pre-process the three-dimensional model to set up the rapid prototyping process parameters and the post-processing of the parts.Gear semi-precision parts of the straight tooth gear master mold,and then this entity as the investment casting mold injection mold casting casting to be refined finishing batch straight tooth gear semi-refined parts?The study show that this paper introduced a rapid manufacturing process of straight teeth face gear which is based on the electrochemical machining technology can not only realizes the batch manufacturing of high precision straight teeth face gear,but also can combining the rapid prototyping technology with the investment casting process that belongs to additive material manufacturing technology,so the semi-precision parts of the straight teeth face gears are manufactured in a low cost and in the short time,it solves the problems of high cost,complex process and low efficiency in the traditional batch “reduction of material manufacturing” technology,this method is proved to be correct and feasible.
