Description of the invention (The present invention is a paired helical rotor tooth profile, which can be set between the paired helical rotor tooth profiles in the pump, and can have a smaller gap to make the leakage caused by the pump less It is small, so that the pump can achieve high efficiency. The "pump" is equipped with a paired helical rotor. After the paired helical rotor meshes and rotates relative to each other, it is used to reach the available fluid. "The practicality of pump J is self-evident. In terms of the conventional paired spiral rotors used in pumps in the traditional way, it is included in it. It has a __ group in the pump Relative to the sprayed spiral rotor, a group of relatively meshing spiral rotors are rotated after meshing to achieve the purpose of conveying fluids. However, the above conventional conventional structure has the following disadvantages in actual use. Improvement: Because there is a large gap between a group of relatively meshing helical rotors, this larger gap will cause the pump to leak more easily. When the above leakage occurs After the problem, the efficiency of the pump can be greatly reduced, which can not meet the high demand for pumps. Therefore, the practicability of the conventional conventional spiral rotor is not enough, and it is necessary to improve it. Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperative, the present inventor has actively researched and improved in view of the incomplete design of the existing paired helical rotors. After continuous trials and experiments, he finally developed a practical and practical The main object of the present invention is to provide a paired helical rotor tooth profile. The pair of helical rotor teeth is provided in the system, and each of the intermeshing helical rotor tooth profiles is formed by a spiral.

Description of the invention (3) (II) Drawing number: (1 0) Spiral rotor (2 0) Spiral rotor (3 〇) Tooth shape, please refer to the first As shown in the fifth to fifth figures, the present invention is a paired helical rotor tooth profile, which includes: A pair of relatively meshing paired 螵 rotors (10) (20) are provided in the pump, and the helical rotor (20) In the tooth profile (30), the linear system of one side of the thread is de-meshed by the outer diameter of a spiral rotor (10), the spiral rotor (20) is formed, and the linear system of the other side is formed by a spiral rotor ( The outer diameter and pitch circle of the helical rotor (20) are generated when the helical rotor (20) of the opposite helical rotor (10) is formed, and the linear system on one side is formed by a helical rotor ( 2 〇) the outer diameter of the spiral rotor (1 0) is generated, and the other side of the linear system is generated by a spiral rotor (20) of the outer diameter of the pitch circle and the mesh. As shown, where c represents the distance between the centers of the two spiral rotors (10) (20), and Rb2 and Rt2 represent the spiral German, turtle, cancan, and RU of one of the spiral rotors (work 0), respectively. The system represents the root diameter and external control of another spiral rotor (20), C = Rtl + Rb2 = Rt2 + Rbl, and al, a2, a3, a4 ^ are shown as two spiral rotors (1〇) (2〇 ), The angle formed between each end point of the trajectory and the center of each circle; Η is the pitch of the spiral rotor (Pitch), when it is a single thread, the pitch is applicable to the Chinese national standard (〇sfS) A4 specification 210 X 297 mm) A7 ----------- 5. Explanation of the invention (4) The value between (Pitch) and the lead is the same, so you can find al, a2, a3 by the cosine theorem , A4, and CL represents the size of the gap between the two helical rotors (10) (20), and the situation is the smallest in the fifth figure. As shown in the sixth to ninth figures, Most of them are the same as those in the second to fifth figures, but the difference is that the one shown in the ninth figure is the gap between the tooth shapes (30) of the two spiral rotors (10) (20) is most In this case, the tooth shape can be formed in a conjugate manner by a conical curve. The main design feature of the present invention is: a3_al + a2 — a4 / 1 0 0 2CL / Hga3 — al + a2 — a4 / 3 6 The value between 0 is the best. When used with the combination of the above structures, when a set of opposing spiral rotors (1 0) (2 ◦) rotates relative to each other, the two The gap between the tooth shapes of the spiral rotor (1 0) (2 0) can be achieved with a smaller gap so that the leakage of Guopu can be smaller, so as to achieve a higher efficiency that can be produced by Guopu. Therefore, according to the above description, it can be known that the present invention has at least the following advantages in an excellent structural configuration; printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs • III ir '--- (Please read the note on the back first Please fill in this page again) —Line.
