Abstract
With a retainer for the cam-type axial piston pump of piston shoes, the hole of its restriction piston shoes movement locus is imperfect circular hole.The retainer of this structure is realizing its restriction piston shoes motion, and provides on the basis of return force for piston shoes, alleviates the weight of component.
Description
Technical field
The utility model relates to a kind of plunger pump, particularly a kind of inclined disc type axial fuel oil plunger pump with piston shoes.
Background technique
The retainer (with reference to Fig. 2) of the existing cam-type axial piston pump with piston shoes, the hole of restriction piston shoes motion is all complete circular hole.
Summary of the invention
The purpose of this utility model: for plunger pump development, its technical requirement weight is more and more lighter, therefore needs the requirement taking into full account weight in the design of component, has ensured that plunger pump complete machine weight is up to standard.Design a kind of novel retainer, the hole of its restriction piston shoes motion is imperfect circular hole, reduces the weight of retainer.
The technical solution of the utility model: according to track and the neck size of piston shoes motion, determine to keep the size of frame aperture and the scope of imperfect circular hole, the part do not coordinated with piston shoes is machined away.
With the retainer of the cam-type axial piston pump of piston shoes, retainer is ring, and the inner port edge of annulus is evenly distributed with the imperfect circular hole of several axis of laying piston shoes.
The diameter of imperfect circular hole should ensure and piston shoes Spielpassung.
When the distance distributed between imperfect circular hole should ensure that piston shoes are laid, mutual portion interferes.
Advantage of the present utility model: the weight reducing retainer.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the retainer of the existing cam-type axial piston pump with piston shoes;
Fig. 2 is the schematic diagram of the retainer of the novel cam-type axial piston pump with piston shoes of this use;
Fig. 3 is the use schematic diagram of the retainer of the novel cam-type axial piston pump with piston shoes of this use.
Embodiment
Embodiment:
With a retainer for the cam-type axial piston pump of piston shoes, it lays and limits the hole of piston shoes movement locus for axial imperfect circular hole.
The diameter of imperfect circular hole should ensure and piston shoes Spielpassung.
When the distance distributed between imperfect circular hole should ensure that piston shoes are laid, mutual portion interferes.
The integrity degree of imperfect circular hole should ensure piston shoes not from wherein deviating from along annulus radial direction.
The retainer of this structure is realizing its restriction piston shoes motion, and provides on the basis of return force for piston shoes, alleviates the weight of component compared to original complete circular hole retainer.
