Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 4, the rotatable profile shapes structure of a kind of external thread rotary, comprise profile shapes cylindrical shell 1 and helical vertically hung scroll 2, described profile shapes cylindrical shell 1 inside is provided with cross section and does not have vicissitudinous rib 3 and hollow cylinder 4, described helical vertically hung scroll 2 along extruding the sectional shape in direction, size, area all do not change, but have the center line along a setting to rotate a certain angle between every layer cross section.
Further, external screw thread rotation formula profile shapes carries out equidistant intercepting, and the helical vertically hung scroll cross section 5 angle of swing difference each other of gained is equal, and is directly proportional with the distance multiple intercepted.
Further, the volume with the profile shapes of described helical vertically hung scroll 2 and the profile shapes of straight burr vertically hung scroll of equal length, equal initial cross-section is equal, but compared with between the surface area of helical vertically hung scroll with straight burr vertically hung scroll, have large increase, the amplitude of increase and the lift angle of spiral are inversely proportional to.
Further, the shape of described helical vertically hung scroll 2 can adopt different geometrical shapies according to function and purposes, it is such as needed to increase radiating effect, just helical vertically hung scroll cross section 5 need be set to the slender type being beneficial to heat radiation, as needs are used as spiral gear, just helical vertically hung scroll cross section 5 tooth-formation of gear need be set to, as needs increase resistance to deformation degree, just helical vertically hung scroll cross section 5 isosceles trapezoid can be set to.
Further, the sectional shape in described helical vertically hung scroll cross section 5 can be complex combination, to reach MULTILAYER COMPOSITE effect simultaneously, can enhance heat, can non-deformability be strengthened again, and can do swing pinion use.
The working principle of the present embodiment is as follows:
By structure as shown in Figures 1 to 4, can be profile shapes cylindrical shell 1 by the segmentation of structures of rotatable for external thread rotary profile shapes, helical vertically hung scroll 2, traditional type rib 3, intercept the cross section of the rotatable profile shapes of external thread rotary, be summarized as two-part, a part is the shape in cross section, size, position, angles etc. do not do the rib 3 of any change, hollow cylinder 4 and profile shapes cylindrical shell 1, another part is exactly the shape in cross section, size is constant, but position, the changing profile shapes cylindrical shell 1 of angle, helical vertically hung scroll 2, the cross section of profile shapes cylindrical shell 1 can be rotate, also can be non-rotary, so ceaselessly extrusion moulding special shapes, just obtain the rotatable profile shapes of external thread rotary that we want.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
