The invention relates to a method for obtaining a gear tooth surface model of a face gear, comprising the following steps: S1, solving the tooth surface equation of a gear cutting tool; The tooth surface is intercepted in front of the tool to obtain the cutting edge curve of the tooth turning tool; S2, establishing the kinematic relationship of surface turning gear processing; S3, obtaining the processing tooth surface of the workpiece tooth surface according to the cutting edge curve equation and kinematic relationship of the turning tool Equation; S4. According to the above equation, insert the tool and processing parameters to establish the discrete points of the tooth surface of the face gear, so as to generate the tooth surface model of the tooth surface gear in the three-dimensional software. The method of the invention can realize the solution of the tooth surface equation of the face gear turning, thereby generating the tooth surface model of the turning tooth surface gear in the three-dimensional software, which greatly facilitates the design, processing and manufacturing of the turning tooth of the face gear.
Description
The method of obtaining the tooth surface model of the face gear technical field The present invention relates to the field of face gear turning tooth processing, more particularly, to a kind of face gear turning tooth tooth surface model. get method. Background technique [0002] The face gear machining technology is a recently developed face gear machining new technology, which has the advantages of high machining efficiency, high It has the characteristics of good flexibility and high processing accuracy. However, the geometry of the tool and the machining motion are more complicated, which can solve the problem of the actual machining of the tooth surface. greater difficulties. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a kind of acquisition method of the face gear tooth surface model, which can Build a 3D model of the real tooth surface of the face gear. The technical scheme that the present invention ...
