Abstract
A kind of adjustable damping slot active distributing construction, including cylinder body, stepper motor and controller, the cylinder interior are equipped with plunger, bushing is cased on the plunger, plunger side is equipped with piston shoes, and the piston shoes side is equipped with swash plate, and the swash plate is equipped with boots slot, swash plate side is equipped with transmission shaft, the cylinder interior side is equipped with valve plate, and lead screw is equipped among valve plate, and valve plate is equipped with damping slot, it is connected with stepper motor above the lead screw, the stepper motor is connect with controller.The utility model is fixedly connected with mode with swash plate using transmission shaft, reduce the pressure difference between every two plunger, it realizes that plunger pushes hydraulic oil smooth transition, reduces oil suction pressure difference, reduce the intensity of noise, simultaneously, stepper motor drives lead screw to adjust damping slot cornerite size, according to axial plunger pump running parameter, adjusts damping slot structural parameters in real time, keep plunger cavity pressure transition gentle, realizes the vibration and noise reducing actively adjusted.
Description
Technical field
The utility model belongs to oil pump technology field more particularly to a kind of adjustable damping slot active distributing construction.
Background technique
Axial plunger pump has many advantages, such as that rated operating pressure is high, power limit is big, variable is easy to adjust, widely applies
In industrial hydraulic and walking Hydraulic Field.In face of the competition of fast-developing Electrified Transmission, hydraulicdriven axial plunger pump
Continue to high-pressure trend, high speed, digitized trend development, to adapt to high pressure grade and high limit revolving speed, axial plunger pump
Noise reduction require it is also increasingly strict.Currently, axial plunger pump is not sleekly to be transitioned into each plunger and column due to pump pressure oil
Fill in cavity pressure it is uneven and can not smooth transition, cause existing plunger pump still to have the defects that noise is big, this is to industrial production
Biggish noise pollution is all produced with running gear, noise is completely eliminated and is difficult to accomplish, therefore by plunger pump
External structure design by noise it is near it is minimum be axial plunger pump apply upper level guarantee.
Summary of the invention
To solve the problems, such as that existing column exists to plunger pump, the utility model, which provides one kind and can reduce axial plunger pump, makes an uproar
The adjustable damping slot active distributing construction of sound.
Technical solution adopted in the utility model:
A kind of adjustable damping slot active distributing construction, including cylinder body, stepper motor and controller, the cylinder interior peace
Equipped with plunger, bushing is cased on the plunger, plunger side is equipped with piston shoes, and the piston shoes side is equipped with swash plate, the swash plate
It is equipped with boots slot, swash plate side is equipped with transmission shaft, and the cylinder interior side is equipped with valve plate, is equipped with silk among valve plate
Thick stick, valve plate are equipped with damping slot, are connected with stepper motor above the lead screw, the stepper motor is connect with controller.
The transmission shaft is fixedly connected with swash plate.
The piston shoes are connect with boots slot activity.
The lead screw, which moves up and down, adjusts damping slot cornerite size, and damping slot is in three-legged structure shape.
The utility model has the beneficial effects that being fixedly connected with mode with swash plate using transmission shaft, reduce between every two plunger
Pressure difference, realize plunger push hydraulic oil smooth transition, reduce oil suction pressure difference, reduce the intensity of noise, meanwhile, stepper motor
It drives lead screw to adjust damping slot cornerite size, according to axial plunger pump running parameter, adjusts damping slot structural parameters in real time, make column
Fill in the vibration and noise reducing that cavity pressure transition is gentle, and realization is actively adjusted.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
The embodiment of type is set forth.
As shown in Figure 1, a kind of adjustable damping slot active distributing construction, including cylinder body 1, stepper motor 12 and controller
10, plunger 3 is installed inside the cylinder body 1, bushing 2 is cased on the plunger 3,3 side of plunger is equipped with piston shoes 9, the piston shoes 9
Side is equipped with swash plate 7, and the swash plate 7 is equipped with boots slot 8, and 7 side of swash plate is equipped with transmission shaft 6,1 interior side of cylinder body
Equipped with valve plate 4, lead screw 11 is installed among valve plate 4, valve plate 4 is equipped with damping slot 5, is connected with above the lead screw 11
Stepper motor 12, the stepper motor 12 are connect with controller 10.
The transmission shaft 6 is fixedly connected with swash plate 7.
The piston shoes 9 are connect with 8 activity of boots slot.
The lead screw 11, which moves up and down, adjusts 5 cornerite size of damping slot, and damping slot 5 is in three-legged structure shape.
The specific work process of the utility model: swash plate 7 is fixedly connected with transmission shaft 6, in the uniform mounting post in 7 side of swash plate
Plug 3, under external force driving, plunger 3 moves transmission shaft 6 with swash plate 7, realizes oil suction movement, meanwhile, controller 10 is according to axis
To the working condition of plunger pump and the opening and closing of operating parameter control stepper motor 12, lead screw 11 is driven to adjust 5 cornerite of damping slot big
It is small, realize the noise abatement campaign of plunger pump.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
