Pump.
Background technology
Dynamical element of the hydraulic pump as hydraulic system, technology are also evolving always and increasingly mature.It is dynamic in original
Machine is when swinging input（The utilization of wave energy and wind energy）, need and swing hydraulic pump to carry out the conversion and utilization of energy.Together
When, the present invention is also used as the use of novel swing hydraulic motor, is used in the occasion for needing to swing output.Since radial load is flat
Balanced oscillating pumps（Motor）Hydraulic Elements are swung for plunger-type Hydraulic Elements with existing vane type to compare, output power and use
Efficiency all highers are compared with existing plunger class component, and transmission shaft radial force balance improves the stress of the standard components such as bearing
Situation extends the service life of element.
Invention content
The present invention provides a kind of inclined disc type oscillating plunger pump of balanced radial force, the invention is in original inclined disc type axial columns
On the basis of plug pump, swash plate and cylinder body are changed to structure symmetrical above and below, keep oil pressure plunger symmetrical about drive shaft axis, eliminated
The radial force of transmission shaft, extends the service life of pump.
Used technical solution is the present invention to solve above-mentioned technical problem：A kind of inclined disc type swing of balanced radial force
Plunger pump, including transmission shaft, swash plate, piston shoes, plunger, retracting spring, cylinder body, oil sucting one-way valve, pressure oil check valve etc., feature
It is：Described transmission shaft one end is connected with prime mover, and the swash plate is driven to be swung；The plunger is slidedly assemblied in the cylinder
In the plunger hole of body, the retracting spring is mounted between plunger and cylinder body plunger hole, and retracting spring is in compressive state, in institute
Under the constraint for stating swash plate, cylinder body and retracting spring, plunger does front-rear reciprocation movement；The piston shoes play static pressure branch in plunger base
The effect of support；The oil sucting one-way valve, pressure oil check valve are connected by the hole of oil pipe and cylinder base respectively, play flow work
With.
The swash plate is upper and lower two symmetrical half inclined-planes there are two inclined-plane, inclined-plane, and swash plate is swung with transmission shaft；The cylinder
Body is retaining element, and plunger hole both sides above and below cylinder body are symmetrical, outside outmost two plunger holes in the cylinder body center of circle and every side
The angle of circle tangent line is the full swing angle of pump.
By the thrust on inclined-plane when the plunger piston slippery boots group pressure oil, when oil suction（Backhaul）What is relied on is the retracting spring
Elastic force, flow mode are Flat valve.
The beneficial effects of the invention are as follows：The invention is due to being that the plunger type of balanced radial force swings Hydraulic Elements and existing
Vane type swing Hydraulic Elements compare, output power and service efficiency all highers are compared with existing plunger class component, transmission
Axis radial direction stress balance, improves the stressing conditions of the standard components such as bearing, extends the service life of element.

Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the inclined disc type oscillating plunger pump of a kind of balanced radial force, including transmission shaft 1, swash plate 2,
Piston shoes 3, plunger 4, retracting spring 5, cylinder body 6, oil sucting one-way valve 7, pressure oil check valve 8 etc., it is characterised in that：The transmission shaft 1
One end is connected with prime mover, and the swash plate 2 is driven to be swung；The plunger 4 is slidedly assemblied in the plunger hole of the cylinder body 6
In, the retracting spring 5 is mounted between 6 plunger hole of plunger 4 and cylinder body, and retracting spring is in compressive state, in the swash plate
2, under the constraint of cylinder body 6 and retracting spring 5, plunger 4 does front-rear reciprocation movement；The piston shoes 3 play static pressure branch in 4 bottom of plunger
The effect of support；The oil sucting one-way valve 7, pressure oil check valve 8 are connect by oil pipe with the hole of 6 bottom of cylinder body respectively, play flow
Effect.
For the tool of the swash plate 2 there are two inclined-plane, inclined-plane is upper and lower two symmetrical half inclined-planes, and swash plate 2 is swung with transmission shaft 1；
The cylinder body 6 is retaining element, and plunger hole is symmetrical in about 6 both sides of cylinder body, 6 center of circle of cylinder body and every outmost two of side
The angle of plunger hole outer circle tangent line is the full swing angle of pump.
When swash plate rotates clockwise（In terms of cylinder base direction）, the plunger 4 of upper left and bottom right moves closer to tiltedly in cylinder body 6
Disk center line, swash plate 2 push plunger 4 to carry out pressure oil, and oil sucting one-way valve 7 is closed, and pressure oil check valve 8 is opened；Lower-left and the right side in cylinder body 6
On plunger 4 be gradually distance from swash plate center line, retracting spring 5 pushes plunger 4 to carry out oil suction, and corresponding oil sucting one-way valve 7 is opened, pressure
Oily check valve 8 is closed.When swash plate rotates counterclockwise, the state of each part mentioned above is opposite
The operation principle of the present invention：The present invention has done the change in structure to the swash plate of original cam-type axial piston pump, one
A inclined-plane is changed to two symmetrical half inclined-planes up and down, changes simultaneously housing structure, and making cylinder body plunger hole, both sides are symmetrical up and down,
The press oil port of both sides is symmetrical relative to drive shaft axis up and down at this time, thus the radial direction of cylinder body and transmission shaft is eliminated in pressure oil
Stress improves the stressing conditions of the standard components such as bearing, extends the service life of pump.
