Description
Technical field
The present invention relates to plunger pump field, more particularly, to a kind of axial plunger pump.
Background technology
Hydraulic pump is the dynamical element of hydraulic system, due to industrial development, and current hydraulic pump is generally required in high speed, high pressure
In the environment of work, and be most commonly used that axial plunger pump now, and traditional high speed plunger pump mainly has two kinds, and one kind is logical
Shaft type axial plunger pump, its work is to drive cylinder body and plunger to rotate together by power transmission shaft, and cylinder body is relatively rotated with oil distribution casing
Relatively rotated with oil, plunger and pitch, plunger produces reciprocating motion, and reaches the effect of oil suction force feed, and another is cambered axle
Formula axial plunger pump, i.e. power transmission shaft have an angle with Boring mill, drive cylinder body together to rotate during main axis, and plunger produces reciprocal
Motion, produces the effect of oil suction force feed.But but both constitutional detail numbers are a lot, and kinematic pair is a lot, works as movement velocity
Very high, when pressure is very big, the relative motion part between its part easily produces abrasion, part of damage and hydraulic pump, to hydraulic pressure system
The security of system brings hidden danger.
The content of the invention
It is an object of the invention to provide a kind of number of parts is few, the friction between kinematic pair is small, the high axial columns of reliability
Fill in pump.
According to an aspect of the present invention, oscillating disc axial plunger pump, including main shaft, swing mechanism, plunger, oil extracting machine
Structure, force feed mechanism, housing and cylinder body, wherein swing mechanism and main shaft connection, plunger at one end and swing mechanism connection, other end peace
In cylinder body, oil suction mechanism and force feed mechanism connection, main shaft and swing mechanism are installed in housing, oil suction mechanism and force feed
Mechanism is installed in cylinder body, housing and cylinder body connection.
The beneficial effects of the invention are as follows：It is of the invention mainly plunger is back and forth transported by the dynamic swing mechanism of main shaft rotating band
Dynamic, so as to realize the course of work of oil suction force feed, the use of swing mechanism reduces the movement velocity and pressure of kinematic pair, significantly
The abrasion between part is reduced, reliability and the life-span of plunger pump is added, and compare the number of parts of traditional plunger pump more
It is few, reduce manufacturing cost.
In some embodiments, wherein main shaft is arranged in housing by bearing, and main shaft is provided with axis hole, axis hole and swing
Axle matches.Main shaft is arranged in housing using bearing can effectively reduce the friction of main shaft, and set axis hole to ensure

Swinging axle one end is arranged in axis hole, and the other end is sequentially installed with pressing plate and rag iron spring, and swinging axle is arranged on pendulum by bearing
In Moving plate, wobble-plate is movably arranged in swing seat, and swing seat is fixed in housing.Because swing mechanism is come using oscillating motion
The traditional rotation of substitution, its range of movement is small, and makes its operating rate and pressure small.
In some embodiments, plunger includes plunger body and piston shoes, and wherein plunger body and piston shoes is flexibly connected, and piston shoes lead to
Pressing plate is crossed to be fixed on wobble-plate.Because the plunger body and piston shoes of plunger are flexibly connected, therefore plunger can driven in wobble-plate
When, piston shoes can protect plunger body greatly not damaged very much because of the amplitude of motion.
In some embodiments, wherein cylinder body is provided with fuel feed hole and oil outlet, also there is cavity between plunger and cylinder body, enters
Oilhole, oil outlet and cavity are all interconnected.Because cavity and multiple working holes are all connected, therefore can be by changing the big of cavity
The small process to realize oil suction oil-feed.
In some embodiments, oil suction mechanism includes oil suction valve body, oil suction valve element and oil suction spring, wherein oil suction valve body
In cylinder body, oil suction valve element and oil suction spring are arranged in oil sucting valve body, oil suction spring one end and the connection of oil suction valve element, separately
One end and cylinder body connection, oil suction valve body are provided with oil-sucking hole.Because oil suction mechanism can make suction by changing the state of oil suction spring
Fuel tap core withstands or unclamped oil-sucking hole, therefore the work of Neng Shi oil suctions mechanism does not influence the work of other mechanisms.
In some embodiments, force feed mechanism includes force feed valve body, force feed valve element and force feed spring, wherein pressing oil valve body
In cylinder body, force feed valve element and force feed spring are arranged in cylinder body, force feed spring one end and force feed valve element connection, the other end
