Embodiment
Below in conjunction with accompanying drawing, the present invention is done detailed explanation.
Screw air compressor of the present invention comprises two screw rods, and wherein a screw rod is three screw rods, and another root screw rod is six screw rods.
Fig. 1 shows the shape of six screw rod radial cross sections of the present invention, and the profile of tooth of every screw rod of six screw rods is identical, and evenly distributes along circumference, and wherein one is linked in sequence by radial alignment ab, generalized cycloidal bc, circular arc line cd and top circle camber line de and forms; Wherein, top circle camber line de is with o
1Be one section circular arc of the top circle in the center of circle, o
1Be the symmetry center of the screw molded lines of six screw rods, circular arc line cd is to be the circular arc in the center of circle with the p point, its radius be the Outside radius of six screw rods and three screw rods the root radius sum 2/3rds, the p point is positioned at straight line o
1On the elongation line of c; Radius and the radian of top circle camber line de are all adjustable, the length-adjustable of radial alignment ab.
Fig. 2 shows the shape of three screw rod radial cross sections of the present invention, the profile of tooth of every screw rod of three screw rods is identical, and be symmetrically distributed along circumference, wherein one is linked in sequence by root circle camber line e ' d ', generalized cycloidal d ' c ', envelope c ' b ', generalized cycloidal b ' a ', circular arc line a ' f ' and generalized cycloidal f ' g ' and forms; Wherein, root circle camber line e ' d ' is with o
2Be one section circular arc of the root circle in the center of circle, o
2Be the symmetry center of the screw molded lines of three screw rods, circular arc line a ' f ' is to be the circular arc in the center of circle with the q point, its radius be the Outside radius of six screw rods and three screw rods the root radius sum 1/3rd, the q point is positioned at straight line o
2On a '.
When three screw rods and six screw rods with the speed ratio of 2:1 when rotate in the center of circle separately, generalized cycloidal bc is the conjugate curve that formed on six screw rods in three a ' on the screw rod o'clock on six screw rods, radial alignment ab is three conjugate curve that the envelope b ' c ' on the screw rod forms on six screw rods on six screw rods, on three screw rods generalized cycloidal a ' b ' and c ' d ' be respectively six on the screw rod the b point and the conjugate curve that on three screw rods, formed in a o'clock, generalized cycloidal f ' g ' is six d on the screw rod o'clock conjugate curve that form on three screw rods, and circular arc line a ' f ' is six conjugate curve that the circular arc line cd on the screw rod forms on three screw rods.
The radian of circular arc d ' e ' is the twice of the radian of circular arc de on six screw rods on three screw rods.
The helical pitch of six tooth shape of screw is twices of three screw rods, and the two screw rods rotation direction is opposite.
Fig. 3 shows the meshing relation of two screw rods correspondence of the present invention, the pitch curve of six screw rod top circle de correspondences is root circle d ' e ' of three screw rods, put a ' on three screw rods corresponding to generalized cycloidal bc on six screw rods, point b and some a correspond respectively to generalized cycloidal a ' b ' and generalized cycloidal c ' d ' on three screw rods on six screw rods, radial alignment ab was corresponding to the envelope b ' c ' on three screw rods on six screw rods corresponding to generalized cycloidal f ' g ' on three screw rods in d o'clock on six screw rods.
As shown in Figure 4, when two screw rods rolled relatively, six screw rods will form the space pitch curve on three screw rods, and three screw rods also can form corresponding pitch curve on six screw rods.Because it is continuous rotating, two pitch curves have been blocked the input cavity and the output cavity of air compressor, and constantly push ahead, thereby produce compressed fluid.
The foregoing description is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
