Description
Technical field
The utility model relates to bent axis type axial piston pump field, particularly relates to the double axial piston pump of a kind of clino-axis type.
Background technique
Plunger in angle type axial piston pump is driven by drive plate, and force in radial is very little, and the tilting moment that cylinder body is subject to is very little, and evenly, leakage loss is little, and volumetric efficiency is high, and frictional loss is little, and mechanical efficiency is high for the laminating of cylinder body end face, oil distribution casing.Therefore the extensive use in industrial hydraulic field is obtained, but traditional angle type axial piston pump only has single plunger, so its flow value exported is little, in the hydraulic system occasion of a lot of large discharge, single angle type axial piston pump cannot meet usage requirement.
Summary of the invention
The utility model is overcoming the deficiency on above conventional art, proposes the double axial piston pump of a kind of clino-axis type.
Concrete summary of the invention of the present utility model is as follows:
The double axial piston pump of a kind of clino-axis type, is made up of bevel gear I, pump shaft, key, bevel gear II, axle sleeve, drive plate, plunger, cylinder body, thrust plate, pump case I, bolt assembly, pump case II, flow cover, screw, bearing;
Described bevel gear I is connected on pump shaft, pump shaft is provided with key, with bevel gear I engage be bevel gear II, bevel gear II is connected on drive plate, drive plate is provided with plunger, bearing, axle sleeve is had between bearing and bevel gear II, the plunger of pump is arranged in the plunger hole of cylinder body, between cylinder body and pump case II, thrust plate is installed, boss on pump case II is embedded in the inside grooves of thrust plate, be connected by bolt group between pump case I with pump case II, be connected by screw between flow cover and pump case II.The double axial piston pump of described clino-axis type has the plunger of two drained full same sizes.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging double plunger, the single inclined shaft axial piston pump making this clino-axis type double axial plunger pump delivery compare same plunger size doubles, and two row plunger measure-alike, on the axial direction of drive plate, axial force can be cancelled out each other, plunger pump gets into smooth, and vibration is little, noise is low, stability of flow.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is bevel gear I; 2 is pump shaft; 3 is key; 4 is bevel gear II; 5 is axle sleeve; 6 is drive plate; 7 is plunger; 8 is cylinder body; 9 is thrust plate; 10 is pump case I; 11 is bolt assembly; 12 is pump case II; 13 is flow cover; 14 is screw; 15 is bearing; Y1, Y2 are hydraulic fluid port.
Embodiment
In order to make scheme of the present utility model, advantage clearly understands, is further elaborated to the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is the double axial piston pump of a kind of clino-axis type, is made up of bevel gear I 1, pump shaft 2, key 3, bevel gear II 4, axle sleeve 5, drive plate 6, plunger 7, cylinder body 8, thrust plate 9, pump case I 10, bolt assembly 11, pump case II 12, flow cover 13, screw 14, bearing 15;
As shown in Figure 1, the agent structure of the double axial piston pump of the utility model clino-axis type is symmetrical about the center line of pump shaft 2, component and the mounting type of both sides are just the same, in order to more clearly demonstrate structure, lower mask body is described in detail: described bevel gear I 1 is connected on pump shaft 2, pump shaft 2 is provided with key 3, with bevel gear I 1 engage be bevel gear II 4, bevel gear II 4 is connected on drive plate 6, drive plate 6 is provided with plunger 7, bearing 15, axle sleeve 5 is had between bearing 15 and bevel gear II 4, the plunger 7 of pump is arranged in plunger 7 hole of cylinder body 8, thrust plate 9 is installed between cylinder body 8 and pump case II 12, boss on pump case II 12 is embedded in the inside grooves of thrust plate 9, be connected by bolt group between pump case I 10 with pump case II 12, flow cover 13 is connected by screw 14 with between pump case II 12, screw 14 can effectively fix flow cover 13 and and pump case II 12 between relative position.The Internal and external cycle location of bearing 15 is that the boss leaning on axle sleeve 5 and pump case I 10, flow to overlap 13 completes.
Its specific works process is as follows: extraneous motor or internal-combustion engine pass through coupling, key 3 connects pump shaft 2, the main shaft of motor or internal-combustion engine rotarily drives the rotation of pump shaft 2, while pump shaft 2 rotates, bevel gear I 1 is also rotated, because bevel gear I 1 engages with bevel gear II 4, bevel gear II 4 is also and then rotated, the drive plate 6 be connected with bevel gear II 4 rotates, thus drive plunger 7 and cylinder body 8 rotate, along with plunger 7 and the rotation of cylinder body 8 and the change of actual volume, plunger 7 realizes suction oil, the fluid of flowing overlaps the effect of 13 through thrust plate 9 and flow, achieve the turnover oil of plunger pump.The utility model is realizing under double bent axis type axial piston pump, and structure is simple, easy accessibility, and flow is large, and operational shock is little, noise is low, stability of flow.
