Definitions

  • the present invention relates to the field of automobiles, and more particularly to a hydraulic blade motor (vane pump).
  • BACKGROUND OF THE INVENTION Hydraulic blade motors (vane pumps) have long been used, but from the structure of existing hydraulic blade motors, the inlet and outlet of hydraulic oil are distributed on both sides of the rotor, and there is a flow distribution at both ends of the rotor. The components of the disc. When the hydraulic blade motor is operated, the hydraulic oil must pass through the inlet and outlet of the rotor, and then through the distribution plate to enter (out) into the middle of the blade, push the blade, and then flow out from the other end of the rotor.
  • the inventors have found that at least the following problems exist in the prior art: Since the oil passage through which the hydraulic oil flows is narrow and tortuous, not only the flow resistance of the hydraulic oil is increased, but the efficiency is lowered, and it is difficult to further enlarge the cross-sectional area of the oil passage. Therefore, the existing hydraulic blade motors (vane pumps) are mostly used on CNC machine tools, and cannot be used in some cases where high speed and high torque (high flow rate) are required.
  • SUMMARY OF THE INVENTION The present invention is directed to a high-speed, high-torque hydraulic blade motor (vane pump) that is simple in structure, low in cost, high in efficiency, high in speed, and high in torque, and is suitable for various occasions.
  • a hydraulic vane motor comprising a stator and a bladed rotor, wherein the vane is mounted in a vane groove of the rotor, and is slidable along the vane slot, and the vane slot is further loaded There is a spring and the spring is at the bottom of the blade. Further, two sets of hydraulic oil inlet and outlet ports are opened on the stator, and four hydraulic oil distribution oil grooves are opened on the transition surface of the inner curved surface of the stator, and the distribution oil tank position is symmetrically located at the hydraulic oil inlet and outlet ports, adjacent to the two A sealing arc is left between the hydraulic oil distribution oil grooves.
  • a triangular relief groove is disposed between the two ends of the oil groove and the sealing arc.
  • the top surface of the blade is a circular arc surface.
  • Fig. 1 is a schematic structural view of a hydraulic blade motor (vane pump) of the present invention. DETAILED DESCRIPTION OF THE INVENTION The present invention will be further described in detail below with reference to the accompanying drawings. Fig.
  • the hydraulic blade motor of the present invention comprises a stator 1 and a rotor 2 equipped with blades 8, wherein the rotor 2 is provided with blades 8 mating vane groove, the spring slot 7 is first installed in the vane slot, and the vane 8 is installed, so that the spring 7 is located at the bottom of the vane, that is, a spring 7 is arranged between the bottom surface of the vane 8 and the rotor 2, and the vane 8 can slide back and forth along the vane slot.
  • the leakage of the oil in the high pressure zone to the pressure oil zone is reduced.
  • a wider and deeper oil groove 6 is formed in the transition curved surface of the curved surface of the stator 1 , and a groove is formed at both ends of the oil groove 6 and the sealing circle 5 (the inner circular surface of the stator between the two oil grooves)
  • the sealed circular orphans are respectively extended to the sides by 5 degrees corresponding to the arc length, and the triangular unloading grooves are processed in the arc.
  • the rest is the transition surface.
  • the unloading grooves are respectively located on the arc surface of the same radius as the sealing arc, which creates conditions for the smooth transition of the blade, so that the blade motor does not generate oil trapping phenomenon and does not cause pulsation.
  • the top surface of the blade 8 is machined into a circular arc surface having the same radius as the large arc of the stator (currently mostly flat).
  • the contact between the blade 8 and the inner surface of the stator 1 is brought into contact by the previous line, and becomes a surface contact of the same radius of curvature. It can reduce the leakage of oil from the high pressure zone to the pressure oil zone. Since there is lubricating oil between the contact faces, the friction does not increase.
  • the machining accuracy and smoothness of the outer circumference of the rotor 2 and the inner circumference of the stator 1 are improved. Reduce the gap between the rotor 2 and the small arc surface of the stator 1 to the extent of the dynamic fit (previously the gap is 0.5-1 mm).
