It is preferred that, the gap between described shell inner surface and main shaft is 0.03-0.1mm, during rotation, main shaft and housing
Inwall will not be contacted.
It is preferred that, housing lower end is provided with base.
It is preferred that, sealing ring is provided between described end cap and housing, oil sealing is additionally provided between described end cap and main shaft,
Good airproof performance, prevents hydraulic fluid leak.
It is preferred that, the end cap is uniformly distributed along the circumference 4-20 screwed hole, the housing to that should have the screwed hole of equivalent amount,
End cap is bolted on housing.
An airtight chamber can be formed after end cap, housing and main shaft assembling, fluid enters through fuel feed hole approach annular oil groove
Several longitudinal oil groove A of housing enter back into the wedge-shaped oil pocket of uniform on main shaft some groups, and the component perpendicular to main shaft radius is pushed away
Dynamic main axis, helically formula is axially arranged every group of wedge-shaped oil pocket, therefore forms successive advanced state.Main axis is to certain
Angle, fluid is got rid of into longitudinal oil groove B successively again from wedge-shaped oil pocket, the oil extraction release at oil outlet.In fuel feeding and the circulation of oil extraction
In, the formation dynamic equilibrium of this hydraulic motor internal oil pressure.
The beneficial effects of the invention are as follows：
1. hydraulic oil is not fully discharged when discharging oil outlet but small part is discharged, and the hydraulic oil of discharge can lead to
Circuit cycle is crossed to use, so quite save flow；
2. hydraulic oil pushes directly on main shaft point of contact and realizes high pulling torque output and higher rotating speed, so efficiency is very high；
3. described in main shaft two ends can realize two ends simultaneously power output, and output direction of rotation be in the same direction；

Embodiment
According to Fig. 1, Fig. 2 and Fig. 3, a kind of hydraulic motor, including two ends be spindle nose and centre be active section main shaft
8th, the cylinder shell 2 that the active section can be inserted in just, two round end caps 4 for setting up separately at the housing two ends；
6 groups are uniformly distributed along the circumference on the active section with equally spaced wedge-shaped oil pocket 6, the quantity of every group of wedge-shaped oil pocket 6 is for 6 and helically
Shape is arranged, and the difference in height per two neighboring wedge-shaped oil pocket 6 is 30mm, and the depth of each wedge shape oil pocket is 20mm；In the housing 2
Wall one end sets the annular oil groove A12 for being provided with fuel feed hole 1, and the other end sets the annular oil groove B13 for being provided with oil outlet 3, the fuel feed hole 1
With the position of oil outlet 3 upward and position is corresponding, the inwall of housing 2 is also uniformly distributed along the circumference some to hang down with annular oil groove A12
Straight and connection longitudinal oil groove A9, and the longitudinal oil groove B10 that connects vertical with annular oil groove B13, longitudinal oil groove A9 and are indulged
To oil groove B10 quantity it is identical and it is spaced set, longitudinal oil groove A9 do not connect with annular oil groove B13, the longitudinal oil
Groove B10 is not connected with annular oil groove A12；Gap between described shell inner surface and main shaft is 0.05mm；Described end cap 4
It is provided with bearing 5 and oil sealing 7 between main shaft 8, end cap 4 provided with can allow the centre bore that spindle nose is passed through just, and between housing 2
Provided with sealing ring.End cap 4 is uniformly distributed along the circumference 12 screwed holes, and 2 pairs of housing should have the screwed hole of 12, and end cap 4 is solid by bolt
It is scheduled on housing 2.The lower end of housing 2 is additionally provided with base 11.
According to Fig. 4, the present invention needs to use the hydraulic pump 14 of connection fuel tank 15 to be its hydraulic oil needed for supplying, so
Provided with the formation hydraulic oil circuit of pipeline communication hydraulic pump 14 between oil outlet 3 and fuel feed hole 1.The hydraulic oil that oil outlet 3 is discharged is former
Originally fuel feed hole 1 directly can be recycled to by hydraulic pump 14, but be in order to present invention operation and the optimization of service life, oil outlet
Filter 16 is provided between 3 and hydraulic pump 14, contaminant filter is carried out to hydraulic oil, the property of this hydraulic motor is preferably played
Energy.
In use, hydraulic pump forms hydraulic oil from fuel tank 15 after oil suction be output to fuel feed hole 1, into end cap 4, housing 2
The airtight chamber formed with main shaft 8.The flow direction of fluid is exactly the trend of oil pressure in fact, and fluid is from fuel feed hole 1 first by way of annular
Oil groove A12, then flow to the longitudinal oil groove A9 in six roads being connected with annular oil groove A12, the wedge-shaped oil pocket of six groups entered back on main shaft 8
6, in the shape of a spiral, cell wall height is raised each group of wedge-shaped oil pocket 6 successively, so when hydraulic oil impacts wedge-shaped oil pocket wall successively,
Continuously motive force can be produced, promotes main shaft 8 to rotate.When main shaft 8, to rotate to wedge-shaped oil pocket 6 relative with longitudinal oil groove B10
At once, inertia is got rid of to longitudinal oil groove B10 the fluid of wedge-shaped oil pocket 6 successively by tangential force, then flows to annular oil groove B13, from going out
The oil extraction release of oilhole 3.Hydraulic oil is not fully discharged when discharging oil outlet 3 but small part is discharged, the liquid of this small part discharge
Force feed flows through filter 16 by pipeline and carries out contaminant filter, then sucks hydraulic pump 14 again, formation High voltage output be pressed into
Oilhole 1 is recycled, it is possible to save oil mass.
It should be noted that the present invention is operationally, inside can reach the dynamic equilibrium of oil pressure.Longitudinal oil groove A9 number
Amount, longitudinal oil groove B10 quantity and wedge-shaped 6 groups of numbers of oil pocket are identicals, and for the present embodiment, the inner wall even distribution of housing 2 has six
There are six groups of wedge-shaped oil pockets 6 on the road longitudinal direction oil groove A9 and longitudinal oil groove B10 in six roads, main shaft 8, the longitudinal oil groove A9 angle per adjacent twice
Spend for 60 °, per adjacent twice, longitudinal oil groove B10 angle is 60 °, per adjacent longitudinal oil groove A9 with longitudinal oil groove B10 angle
For 30 °, per two adjacent groups, the angle of wedge-shaped oil pocket 6 is 60 °, so wedge shape oil pocket 6 and longitudinal direction oil groove A9 and longitudinal oil groove B10 are equal
It is one-to-one, should be starting point so that one group of wedge-shaped oil pocket 6 is relative with longitudinal oil groove A9, often rotate and complete six fuel feeding once week
With six oil extractions.In the circulation of fuel feeding and oil extraction, main shaft 8 is promoted to rotate, constantly unload in continuous suction pressure inside this hydraulic motor
Pressure maintains the balance of internal oil pressure.
Hydraulic oil pushes directly on the rotation of the point of contact of main shaft 8, and loss during energy conversion, hydraulic pump are reduced to a certain extent
When the oil pressure of 14 fuel feeding suitably increases, this hydraulic motor can realize the output of more high pulling torque and higher rotating speed completely, so have
Very high efficiency.The spindle nose at the two ends of main shaft 8 can output torque, being not only common to needs the plant equipment of single output, can be with
Drive two rotary parts in two groups of plant equipment or same machinery to realize rotating Vortex, expand the applicable model of the present invention
Enclose.
