The mechanical structure is added on the outer side of the main shaft rotor, such as a wind resistance reducing blade or a flow guiding device is added, so that friction resistance between the main shaft rotor and fluid is reduced when the main shaft rotor rotates, distribution of the fluid near the main shaft rotor is improved, and stability of rotor movement can be effectively improved. The change of the structure of the main shaft rotor mainly refers to the change of the cross section shape of the main shaft rotor, the cross section of the common main shaft rotor is circular, and is not the optimal shape capable of reducing wind resistance, and the reasonable cross section shape is sought to improve the contact condition of the main shaft rotor and surrounding fluid, so that the effect of reducing wind resistance is achieved.
However, it is often difficult to reduce wind resistance by adding mechanical structures to the outside of the spindle rotor, which has high requirements for the design and layout of the mechanical structures. The main shaft rotor self structure thought is changed simply and easily, and the requirement on processing equipment is not low.

Detailed Description
The following description of the present invention is provided with reference to the accompanying drawings, but is not limited to the following description, and any modifications or equivalent substitutions of the present invention should be included in the scope of the present invention without departing from the spirit and scope of the present invention.
The invention provides a low wind resistance high speed main shaft rotor structure, as shown in fig. 1-3, comprising a main shaft rotor 1 and a sand hill-shaped body 2, wherein the high speed main shaft rotor structure is different from the prior main shaft rotor in that: the outer side wall of the spindle rotor 1 is provided with 10 sand hill-shaped bodies 2, and the sand hill-shaped bodies 2 are uniformly distributed along the circumferential direction of the outer side wall of the spindle rotor 1.
In the invention, the dune-shaped body 2 is a C-shaped tooth, the upper surface and the left side surface of the C-shaped tooth are integrally provided with an upwardly convex arc surface a, the arc surface a is a convex slope 3, the right side surface of the C-shaped tooth is provided with a concave arc surface b on the left side, and the arc surface b is a concave slope 4. The dune-shaped body 2 simulates the structure of a dune in nature, and the convex slope 3 and the concave slope 4 correspond to the windward slope and the leeward slope of the dune in nature respectively, wherein: the fluid speed at the convex slope 3 is high, and the pressure is low; the fluid speed at the concave slope 4 is low and the pressure intensity is high; when the spindle rotor 1 rotates, the fluid moves from the convex slope 3 to the concave slope 4 along the sand hill body 2, and the fluid easily forms vortex at the concave slope 4.
In the invention, when the spindle rotor 1 runs at a high speed, the fluid around the spindle rotor flows through the convex slopes 3 and the concave slopes 4 of one dune-shaped body 2 in sequence, then flows to the convex slopes 3 and the concave slopes 4 of the next dune-shaped body 2, and the above process is repeated.
In the invention, the convex slope 3 and the concave slope 4 have opposite effects on the speed and the pressure of the fluid, a gap exists between two adjacent sand dune-shaped bodies 2, and when the fluid flows through the gap, under the combined action of the convex slope 3 and the concave slope 4, the friction resistance between the fluid and the main shaft rotor 1 is reduced, so that the wind resistance of the main shaft rotor 1 is reduced when moving at a high speed, and the running stability of the main shaft is improved.
In the invention, the windage resistance is reduced when the spindle rotor 1 runs at high speed due to the sand dune-shaped body 2, the power consumption required for overcoming the fluid resistance is reduced, and correspondingly, the power consumption of a motor driving the spindle rotor 1 to move is also reduced.
