Embodiment 1
[0082] A method for designing a profile of a conical twin-screw rotor with intersecting shafts proposed by the present invention comprises the following steps:
[0083] Such as figure 1 and figure 2 As shown, the first step is to establish the space external meshing model of the conical rotor. OZ in the picture 1 is the axis of rotation of rotor 1, OZ 2 is the axis of rotation of rotor 2, OZ 1 with OZ 2 Intersect at point O and make an angle θ. The meshing relationship of the rotor can be represented by two conical surfaces. The two cones make a pure rolling motion tangentially and their line of contact is always OL, which is called the clockwise axis of revolution. Such as image 3 and Figure 4 as well as Figure 5 and Figure 6 As shown, in the second step, on a series of spherical surfaces with the center of the sphere O and different radii, the profile line family required for the rotor 1 to form a cone is given. The third step is to obtain the conjugate curv...
