Specific embodiments

[0019] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] The high-efficiency micro axial flow distribution motor of the present utility model includes a front housing 1 and a rear housing 9. The rear housing 9 is sequentially connected to the flow distribution valve core 8 and the rotor-stator pair 6. The flow distribution valve core 8 is connected to the output shaft 2 through a flow distribution connecting rod 7. Among them, a spacer disc 3 is provided on the side of the rotor-stator pair 6. The output shaft 2 is connected to the transmission shaft 5. A spline spacer 4 is provided at the flow distribution connecting rod 7. A shaft seal 10 is provided inside the front housing 1. The shaft seal 10 is a skeleton oil seal with a spring.

[0021] During use, the hydraulic oil enters the rear housing 9 and flows into the rotor-stator pair 6 through the flow distribution valve core 8. The oil passage is short and heat-resistant, which can reduce energy loss. A skeleton oil seal with a spring is adopted. This shaft seal 10 can bear a large pressure and the seal can effectively seal. A connecting rod is used to connect the output shaft 2 and the flow distribution valve core 8. After the hydraulic oil enters the flow distribution valve core 8, it drives the valve core to rotate and drives the output shaft 2 to rotate through the connecting rod. Compared with the traditional motor, this structure reduces energy loss and improves efficiency.

[0022] The front housing 1, output shaft 2, spline spacer 4, transmission shaft 5, rotor-stator pair 6, flow distribution connecting rod 7, flow distribution valve core 8, and rear housing 9 of the present utility model are in the state of rough blanks commissioned for processing according to the drawings, and then self-processed into finished parts; the transmission shaft 5 is a self-processed part as a tool; the spacer disc 3 and the shaft seal 10 are commissioned for processing into finished parts; and then assembled by itself to finally form a product.

[0023] The front housing 1 and the rear housing 9 of this utility model are made of QT500-7 material, which has the advantages of convenient molding, easy processing and low price. The sealing element material is selected to be heat-resistant and high-pressure-resistant, and can adapt to the working environment of long-term construction machinery. It has a simple structure, reliable performance, convenient maintenance, and good adaptability to impact loads.
