The utility model discloses a join in marriage class structure and can improve the lubricated effect between two friction surfaces, improve the oil film holding power, reduce the frictional force of friction between vice, improve axial piston motor's efficiency, the life of the impurity extension motor of on the other hand in can storied oil liquid.
Description
Technical field
This utility model relates to technical field of hydraulic elements, particularly to a kind of based on valve plate kinetic pressure balancing
Distributing construction.
Background technology
Axial piston motor, is a kind of fluid conveying being applied to Hydraulic Industry and executive component, owing to having
The advantages such as volume is little, lightweight, power density is big, be widely used in lathe forging and stamping, metallurgy, engineering,
The machinery such as mine, boats and ships and other Hydraulic Power Transmission Systems.
Typically, the structure of axial piston motor mainly includes valve body, housing, swash plate, bearing, skeleton
Oil sealing, housing assembly and valve plate etc., its operation principle is: when hydraulic oil enters housing assembly through valve plate,
Act on the hydraulic coupling on plunger, be converted into the axially-movable of plunger and the cross component force of plunger, produce cylinder
The rotary motion of body, thus cylinder body produces torque, drives other part to operate.
But, the relative motion pair of axial piston motor is more, such as the friction formed between plunger body and cylinder body
Friction pair, the friction pair of swash plate/piston shoes formation and the oil distribution casing/cylinder body that secondary, plunger hole/plunger is formed
The friction pair that end face is formed, therefore there is bigger frictional force in motor, and frictional force produces more energy expenditure,
Produce heat.
In recent years, along with the shortage of world energy sources, the energy-conservation attention increasingly obtaining people.Axial columns Saimaa
The friction pair reached is the key link causing energy loss, therefore reduces the coefficient of friction of each friction pair, is to carry
The key point of high piston motor efficiency.
Utility model content
This utility model, in order to solve the deficiencies in the prior art, reduces and reduces rubbing between valve plate and cylinder body
Wipe, it is provided that a kind of distributing construction based on valve plate kinetic pressure balancing.
For achieving the above object, this utility model uses following technical proposals: a kind of flat based on valve plate dynamic pressure
The distributing construction of weighing apparatus, including valve plate, the flow district of described valve plate is provided with assignment hole and band, described
On band, the Surface Machining at the fuel feed hole of assignment hole and the transitional region of outage has several micropores, institute
Stating micropore is hemispherical and in the fan-shaped arrangement with valve plate center as the center of circle, the equal diameters of described micropore and
For 0.1mm-0.3mm.
Preferably, described micropore equal diameters and be 0.1mm.
Preferably, described micropore equal diameters and be 0.3mm.
Preferably, described micropore equal diameters and be 0.2mm
With improvement, the position that the processing density distance valve plate center of described micropore is remote is more than in distance valve plate
The position that the heart is near.
With improvement, the area of described micropore accounts for the 50%-70% of band area.
Preferably, the area of described micropore accounts for the 50% of band area.
Preferably, the area of described micropore accounts for the 60% of band area.
Preferably, the area of described micropore accounts for the 70% of band area.
The beneficial effects of the utility model are: the flow based on valve plate kinetic pressure balancing that patent of the present invention provides
Structure is designed with micropore on valve plate, and valve plate with bringing two friction tables into by hydraulic oil during cylinder body relative motion
The gap in face is formed pressure-bearing oil film, produces the fluid pressure of supporting load two rubbing surfaces separately, now have
A part of fluid is directly stayed in micropore, and operationally the hydraulic oil in micropore can reach to improve two rubbing surfaces
Between lubricant effect, improve oil film support force, reduce the frictional force between friction pair, improve axial plunger
The efficiency of motor, on the other hand can store the impurity in fluid and extend the service life of motor.
