Embodiment 1
[0088] see Figure 4 , in order to adopt the method of the present invention, inserting the external meshing fifth-order elliptic spur gear with the constant speed of the rotary shaft of the inserting tool to insert the cross-sectional view of the tool position track, the external meshing fifth-order elliptic spur gear pitch curve equation is,
[0089]
[0090] The workpiece to be processed is an external meshing fifth-order elliptical spur gear, and the gear parameters related to processing: semi-major axis A=108.201mm, order n=5, tooth width b=50mm, eccentricity k=0.04, normal modulus m n =4mm, number of gear teeth Z=55, polar angle The determination of processing technology parameters can be selected with reference to the processing of cylindrical gears. Here, it is taken as: the number of teeth of the slotting tool z=18, the number of strokes of the vertical moving axis of the slotting tool is 200 times / min, the radial speed is 1mm / min, and the rotation speed of the s...
Embodiment 2
[0099] see Figure 6 , in order to adopt the method of the present invention, inserting the external meshing six-order elliptic helical gear tool position track sectional view with the constant speed of the inserting tool rotary shaft, the external meshing six-order elliptic helical gear pitch curve equation is the same as formula (12), which is related to processing Gear parameters: semi-major axis A=131.830mm, order n=6, tooth width b=50mm, eccentricity k=0.05, normal modulus m n =4mm, number of gear teeth Z=65, polar angle The rotation direction of the gear is right-handed, and the helix angle is 15 o . The determination of processing technology parameters can be selected with reference to the processing of cylindrical gears. Here, it is taken as: the number of teeth of the slotting tool z=18, the number of strokes of the vertical moving axis of the slotting tool is 200 times / min, the radial speed is 1mm / min, and the rotation speed of the slotting tool is 30° / min. min. ...
