Embodiment Construction
[0098] Such as figure 1 , figure 2 , image 3 In the shown embodiment, the three-segment tooth profile curves are selected in the form of arc curves in the local different sections of the tooth surface, and the optimum point contact pressure angle is determined to realize the general distribution of three-point contact in different sections. Such as figure 1 , 2 As shown, the convex and concave tubular meshing tooth surfaces constructed based on the conjugate curve meshing theory form a paired meshing pair, and the meshing pair moves along the contact point track in the axial direction, and the two are in general three-point contact in the local different sections of the tooth surface;
[0099] The cylindrical helix is selected as the conjugate contact curve of the tooth surface. Such as image 3 As shown, in the space coordinate system l 1 , l 2 and l 3 are three helical curves on the cylindrical surface, satisfying the curve l 2 relative curve l 1 Rotation angle...
