[Prior Art] ή, refer to the application number No. 97211〇22, “Cycloidal Grab Pump”, which has a patented content: a body with a shaft hole in the body, and a body with a body The inlet and outlet ports are connected to each other, and the accommodating groove is outwardly connected and eccentrically disposed with respect to the shaft hole; the outer rotor is disposed coaxially with the accommodating groove and is disposed in the accommodating groove, and is further disposed in the rotor a through hole is formed in a geometric shape, the through hole is coaxially disposed with the shaft hole of the body; a shaft rod is threaded through the shaft hole of the body; and the outer rotor is rotated between the inner portion and the shaft rod The inner rotor of the oil supply is compressed, and the coaxial teeth are again on the shaft; j: the dry and valley is disposed in the through hole, and the inner rotor rotates in the opposite direction; to; the bearing is disposed on the shaft and the bearing is on the shaft The upper part is positioned on at least one side of the body relative to the two sides of the receiving groove; the cover body is disposed at the end of the body to receive the receiving groove. / The above-mentioned four known cycloidal fluid pumps still have the following defects: M358214 Referring to the first figure, the well-known hydraulic pump is full, and its shaft (2) needs to be machined to manufacture two combined planes (2 1 ), ( 2 2 ), and the end face of the shaft (1 1 ) of the motor (丄) is the same, and the joint slot (丄丄丄) is also processed. The joint slot (1 1 1) also needs to be materialized, corresponding to The two combined planes (1 1 2), (1 1 3), the shaft (1 丄丄) groove is difficult to process and the concentricity is not accurate', so that the hydraulic pumping shaft [9, - p coffee, ^ 千田仟 <2) is easy to break 'If it is not easy to heat treatment, the cost is also high, the processing cost of the five-transport structure is high, and the concentricity of the connection is not good and good. The hitting is correct, so the poor transmission efficiency makes the rod (2) easy to break, which is the missing one. Referring to the second figure, in order to change the missing of the above pump, the development of a coupling (3) was developed using _ plus red, 〇 ~ with a shaft seat (3 1 ), ( 3 2 ) are respectively connected to the shaft of the motor and the shaft of the Lipu, and the corresponding faces of the two shaft seats (3 1 ) and (32) are oppositely provided with grooves (3 workers) , (3 2 1) and convex parts (3 12), (3 2?), 廿 — - Eya is provided with an elastic member [q) between the two shaft seats (31) and (3 2 ) I 王仟 I 3 3 ), the tenon (3 3 1 ) of the elastic member (3 3 ) is just spaced apart from the two axis temples (the convex portions of the cliffs (31), (32) (3 1 2 ), ( 3 2 2 ), 掳屮 π According to this, the problem of poor concentricity between the axis and the axis can be obtained by the elastic member (3 3 ), θ 3 ), so that the shaft can not be easily broken, but Need to increase the coupling (3 of 3 is set to 'and the coupling (3) body shell large and take up space, motor and pump θ _ λ fruit / there is a work room can not be installed, x will be longer, and The coupling 芎C qβ I is not 钊μ pregnant (3) and the cost of the connection is high and different, and it still needs to be connected M358214 is based on the problems of the above-mentioned conventional structure, how to develop an innovative and more practical and practical, and the relevant operators must strive to develop breakthrough goals and The direction is wrong. The creator has been working on the development and design of related products for many years. In view of the above objectives, after adding δ and careful evaluation, the author will have a practical and practical creation. 】 The technical problem to be solved: In the daytime hydraulic pumping, the shaft needs to be machined and manufactured into two combined surfaces, and the shaft end of the motor and the shaft of the motor are the same, and the coupling hole is also to be machined. The sample is not easy to process and the concentricity is inaccurate, so that the hydraulic pumping shaft capacity & _, „^ ^ ^ is easy to cultivate, if it is not easy to heat treatment, the cost is also ^, and The connection structure has a high cost of reinforcement.
