The gear parameters of the frontal center are: modulus m=4, tooth number z=9, tooth top coefficient ha=1, tooth top clearance coefficient C=0.25, radial displacement coefficient X=0.4, cross tooth number K=2, public normal line Wn=19.5+0.2 +0.1 (mm), CAXA does not provide professional gear modeling command, can be modeled by function curve, but this method is more complicated and has variation coefficient. The rear shape is more difficult.
The size of the curve groove of the lower part of the part is not easy to guarantee, and the two 90 degree gap is not closed.
There are two different directions of ellipse on the edge of the back of the back, and the center has an inner and outer six petals with circular arcs. There are two arc curve islands in the upper and lower parts. These elements have to reverse the corner in processing. It is more convenient to choose a reasonable shape.
