[0060] Take the addendum arc radius R=65mm, dedendum arc r=33mm, and small arc rr=1mm as an example, the profile line and contact line are as follows figure 2 , image 3 , Figure 4 as well as Figure 5 shown. The center distance of the male and female rotors in the rotor profile of the dry screw vacuum pump is:
[0061] A=R+r=98mm
[0062] The equation of the arc cycloid segment b'c' meshing with the corrected arc segment a'b' is:
[0063]
[0064] The equation of the modified arc segment a'b' is:
[0065]
[0066] where O 1 =(a,b)=(1.3061,63.9867),
[0067] The center of the circle is the intersection of the curve equidistant 1mm outside the arc cycloid segment b'c' and the circle with a radius of 64mm.
[0068] The arc cycloid segment b'c' is tangent to the circle of the corrected arc segment a'b', and the tangent point is N, and the coordinates of N points are brought into the equation of the corrected arc segment a'b' and the arc cycloid segment b The eq...
