Abstract

The invention provides a three-dimensional modeling method for the tooth surface of gear hobbing, including: establishing a three-dimensional model of the tooth blade trajectory surface of a hob, and establishing a three-dimensional model of a gear blank; The three-dimensional model of the blank is set at the initial position of processing, and a three-dimensional model of single-tooth processing is established; using the three-dimensional model of single-tooth processing, the three-dimensional model of the gear blank is subjected to a Boolean operation through the three-dimensional model of the tooth blade trajectory surface of the hob to obtain The full tooth profile three-dimensional model; applying the full tooth profile three-dimensional model, the full tooth profile is repeatedly constructed on the gear blank three-dimensional model, and the hobbing gear three-dimensional model is obtained. The invention establishes a three-dimensional model of the tooth blade trajectory surface of the hob, and simulates the three-dimensional model of the processing gear blank through the three-dimensional model of the tooth and blade trajectory surface of the hob, so that the establishment of the model is better, simpler and more in line with the actual processing situation. It truly reflects the actual surface condition of the gear.

Description

technical field [0001] The invention relates to the field of information technology, and in particular, to a three-dimensional modeling method for gear hobbing processing tooth surfaces. Background technique [0002] To study the surface morphology of gear tooth profile, etc., the common method is the experimental method. The surface roughness of gear hobbing can be measured by using the surface roughness meter, but the experimental cost is high, and it is difficult to reflect the surface roughness and feed rate, milling cutter parameters, gear The direct relationship between the main influencing factors such as parameters. The three-dimensional shape of the tooth surface cannot be obtained. The three-dimensional coordinate measurement method can measure the three-dimensional coordinates of the hobbing surface and build a three-dimensional model of the machined surface, but the experimental cost is high, the efficiency is low, and it is difficult to reflect the surface roug...
