Description
Technical field
The present invention relates to bent axis type axial piston pump field, more particularly to a kind of double axial plunger pump of clino-axis type.
Technical background
Plunger in angle type axial piston pump is driven by drive disk, and force in radial very little, what cylinder body was subject to inclines
Torque very little is covered, cylinder body end face, oil distribution casing fitting are uniform, and leakage loss is small, and volumetric efficiency is high, and friction loss is small, mechanical efficiency
It is high.Therefore the extensive use in industrial hydraulic field is obtained, but traditional angle type axial piston pump only has single plunger, institute
Small with the flow value of its output, in the hydraulic system occasion of many big flows, single angle type axial piston pump can not meet
Requirement.
The content of the invention
The present invention is on above conventional art is overcome the shortcomings of, proposes a kind of double axial plunger pump of clino-axis type.
The specific content of the invention of the present invention is as follows：
A kind of double axial plunger pump of clino-axis type, by bevel gear I, pump shaft, key, bevel gear II, axle sleeve, drive disk, plunger, cylinder
Body, valve plate, pump case I, bolt assembly, pump case II, flow set, screw, bearing composition；
Described bevel gear I is connected on pump shaft, is provided with key on pump shaft, and what bevel gear I engaged is bevel gear II, bevel gear
II is connected on drive disk, and plunger, bearing are provided with drive disk, there is axle sleeve, the plunger peace of pump between bearing and bevel gear II
In the plunger hole of cylinder body, valve plate is installed between cylinder body and pump case II, the boss on pump case II is embedded in valve plate
Inside grooves, connected by bolt group between pump case I and pump case II, be connected by screw between flow set and pump case II.It is described
The double axial plunger pump of clino-axis type have the plungers of two drained exactly the same sizes.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by setting double plunger so that the inclined shaft
The discharge capacity of the double axial plunger pump of formula doubles compared to the single inclined shaft axial plunger pump with plunger size, and two rows
Plunger size is identical, and axial force can cancel out each other on the axial direction of drive disk, and plunger pump gets into smooth with small vibration, noise
It is low, stability of flow.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1 is bevel gear I；2 be pump shaft；3 be key；4 be bevel gear II；5 be axle sleeve；6 be drive disk；7 be plunger；8
For cylinder body；9 be valve plate；10 be pump case I；11 be bolt assembly；12 be pump case II；13 be flow set；14 be screw；15 be axle
Hold；Y1, Y2 are hydraulic fluid port.
Embodiment
In order that the solution of the present invention, advantage are more clearly understood, the present invention is carried out below in conjunction with the accompanying drawings further detailed
Describe in detail bright.
As shown in figure 1, the present invention is a kind of double axial plunger pump of clino-axis type, by bevel gear I 1, pump shaft 2, key 3, cone tooth
Take turns II 4, axle sleeve 5, drive disk 6, plunger 7, cylinder body 8, valve plate 9, pump case I 10, bolt assembly 11, pump case II 12, flow set 13,
Screw 14, bearing 15 form；
As shown in figure 1, the agent structure of the double axial plunger pump of clino-axis type of the present invention is symmetrically divided on the center line of pump shaft 2
Cloth, the parts and mounting means of both sides are just the same, and in order to become apparent from illustrating structure, lower mask body is described in detail：Described
Bevel gear I 1 is connected on pump shaft 2, is provided with key 3 on pump shaft 2, and what bevel gear I 1 engaged is bevel gear II 4, bevel gear II 4
It is connected on drive disk 6, plunger 7, bearing 15 is installed on drive disk 6, there is axle sleeve 5 between bearing 15 and bevel gear II 4, pump
Plunger 7 is arranged in the hole of plunger 7 of cylinder body 8, is provided with valve plate 9 between cylinder body 8 and pump case II 12, the boss on pump case II 12
The inside grooves of valve plate 9 are embedded in, are connected between pump case I 10 and pump case II 12 by bolt group, flow set 13 and pump case II
Connected between 12 by screw 14, screw 14 can effectively fix flow set 13 and the relative position between pump case II 12.
The Internal and external cycle positioning of bearing 15 is completed by axle sleeve 5 and pump case I 10, the boss of flow set 13.
Its specific work process is as follows：Extraneous motor or internal combustion engine connect pump shaft 2 by shaft coupling, key 3, motor or
The main shaft rotation of person's internal combustion engine drives the rotation of pump shaft 2, and bevel gear I 1 also rotates while pump shaft 2 rotates, due to bevel gear I 1
Engaged with bevel gear II 4, bevel gear II 4 also and then rotates, and the drive disk 6 being connected with bevel gear II 4 rotates, so as to drive plunger
7 and cylinder body 8 rotate, with the rotation of plunger 7 and cylinder body 8 and the change of dischargeable capacity, plunger 7 realize suction oil, the oil of flowing
It is fuel-displaced to realize entering for plunger pump by the effect of valve plate 9 and flow set 13 for liquid.The present invention is realizing double inclined plunger
Simple in construction under pump, convenient disassembly, flow is big, and operational shock is small, noise is low, stability of flow.
