It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Please refer to a kind of vane pump for increasing blade lubricity of Fig. 1, comprising:
One pump housing 1,1 both ends of the pump housing offer an inlet port 2 and a press oil port 3 respectively, and the inlet port 2 is for inhaling
Oil, the press oil port 3 are used for pressure oil.
One stator 4, the stator 4 are mounted in the pump housing 1, and the stator 4 is matched with 1 inner cavity of the pump housing, institute
It states stator 4 and plays the role of the connection pump housing 1 and the rotor 5.
One rotor 5, the rotor 5 are mounted in the stator 4, and the rotor 5 is matched with 4 inner cavity of stator, institute
Stating 4 inner cavity of stator is ellipse, and the rotor 5 is nearest in level orientation distance with ellipse 4 inner cavity of stator, in Vertical Square
Position distance is farthest, holds so that constituting work with the rotor 4 and 3 inner surface of the stator by the two adjacent blades 8
Product can first ascending carry out oil suction, then descending oil extraction again.
Between the rotor 5 and the stator 4 formed oil guide groove 6, the oil guide groove 6 respectively with the inlet port 2 and institute
It states press oil port 3 to be connected, be connected at the inlet port 2 and the upper left and bottom right of the oil guide groove 6, the press oil port 3 and institute
It states and is connected at the upper right and lower-left of oil guide groove 6, the link position of the oil guide groove 6 and the inlet port 2 and the press oil port 3
Symmetrically, when work, oil enters from the inlet port 2, respectively from the upper left and the right side of the inlet port 2 and the oil guide groove 6
Lower place, which enters, to be made of in swept volume the two adjacent blades 8 with the rotor 5 and 4 inner surface of the stator, is then led to
The rotor 5 is crossed to rotate, the oil in swept volume further through the press oil port 3 at the upper right of the oil guide groove 6 and lower-left from
The press oil port 3 flows out.
Several mounting grooves 7 are offered on the rotor 5, the mounting groove intermediate ends are equipped with first oil storage tank 9 of circle, described
First oil storage tank 9 is for being lubricated the side wall of the blade 8, during the blade 8 rises, to the blade 8
Comprehensive lubrication is carried out positioned at first oil storage tank 9 side wall below, when the blade 8 decline by lubricated part
Lubricating oil can be remained with the 7 side wall contact position of mounting groove, the part that the blade 8 does not lubricate at this time can be lubricated, from
And accomplish the lubrication of the entire blade 8.
7 bottom end of mounting groove is equipped with the second oil storage tank 10, and second oil storage tank 10 is raised to highest for the blade 8
To the storage of the lubricating oil in first oil storage tank 9, when the blade 8 is preferably minimized place, second oil storage tank when place
Lubricating oil in 10 is back flowed back into first oil storage tank 9 by 8 bottom squeeze of blade to rise.
First oil storage tank 9 and second oil storage tank 10 are provided with lubricating oil.
The bottom that the blade 8 is raised to the blade 8 when highest point is higher than first oil storage tank 9, so that the blade 8
Oil in first oil storage tank 9 described in when rising can be flowed into smoothly in second oil storage tank 10.
Several mounting grooves 7 are equipped with leaf in the mounting groove 7 using the center of circle of the rotor 5 as center array distribution
Piece 8, the blade 8 are matched with the mounting groove 7, and there are certain gaps between the blade 8 and the mounting groove 7.
The blade 8 of adjacent two constitutes swept volume with the rotor 5 and 4 inner surface of the stator, and swept volume is first
Ascending carry out oil suction, then descending oil extraction again, the blade 8, which rotates a circle, completes oil suction twice and oil extraction, twice
The direction of stress is identical, equal in magnitude, and suction, oil extraction are for the bearing of central axis, and without radial force, bearing be can be used most
Common ball bearing.
8 top of blade is semicircle, so that the blade 8 becomes smaller with friction when 4 lumen contact of stator, so that
4 surface of internal cavity of stator keeps smooth, increases its service life.
When the rotor 5 rotates clockwise, when the blade 8 of adjacent two moves to left and right side with the stator 4
Minimum with the rotor 5 closed volume, maximum when upper following, the experience of blade 8 of adjacent two is from left and right sides to upper and lower
The process on side be exactly volume increase process, from it is upper below to the process of left and right side be exactly volume reduce process.
