Abstract
The invention discloses an inclined plate type axial plunger pump with a sliding shoe. The inclined plate type axial plunger pump is characterized in that: an annular inner groove is formed in the center of an inclined surface of an inclined plate for mounting a retainer; the retainer has an annular structure; a hole is formed in an annular band, and is sleeved on the sliding shoe; the sliding shoe and the retainer are arranged in the inner groove; a compaction gasket is used for compacting the rim of the retainer on the peripheral edge of the inner groove, so that the retainer is packaged in the inner groove; the compaction gasket is fixed on the peripheral edge of the inclined plate; a gasket is arranged between the compaction gasket and the inclined plate; and the height of the gasket is used for adjusting a movable gap sigma between the sliding shoe and the retainer in the inner groove. Compared with the prior art, the inclined plate type axial plunger pump has the advantages that: a friction pair consisting of a spherical stopping block and the retainer is eliminated, abrasion during working is reduced, the processing difficulty of the retainer is reduced, and the structure of a product is simplified.
Description
Technical field
The present invention is a kind of cam-type axial piston pump that has piston shoes, belongs to the technical field of structures of product.
Background technique
In the existing cam-type axial piston pump that has piston shoes,, all there are retainer e (also claiming to return dish) and spherical block f with reference to shown in Figure 1.Plunger d also drives retainer e rotation when rotating with rotor h, under the acting in conjunction of retainer e and swash plate b, form continuous to-and-fro motion, under the effect of spherical block f and spring g, piston shoes c is fitted all the time with swash plate b simultaneously.Like this, with regard to the sphere that needs retainer e and spherical block f very high quality of fit is arranged, increased the difficulty of processing of retainer and spherical block, product structure is relative complex also.So the retainer of the existing cam-type axial piston pump that has piston shoes and the difficulty of processing of spherical block are relatively large, also inevitably produce wearing and tearing in the working procedure, life-span and reliability receive certain restriction.
Summary of the invention
The present invention designs to the deficiency that exists in the above-mentioned existing technology just a kind of cam-type axial piston pump that has piston shoes is provided; This plunger pump has removed this part of spherical block; Reduced retainer and spherical block this to friction pair; To avoid the wearing and tearing of its generation, improve life-span and reliability.
The objective of the invention is to realize through following technical measures:
This kind has the cam-type axial piston pump of piston shoes, and this plunger pump mainly comprises main shaft, swash plate, retainer, piston shoes, plunger, spring, rotor and branch food tray, it is characterized in that: the center, inclined-plane that the swash plate of retainer is installed; The inner groovy of a ring-type of processing; Retainer is a loop configuration, on the endless belt processing porose, this borehole jack is contained on the piston shoes; Piston shoes and retainer are arranged in this inner groovy; Push down the edge of retainer in the perimeter of inner groovy with packing washer, retainer is encapsulated in the inner groovy, packing washer is fixed on the periphery of swash plate; A packing ring is set between packing washer and the swash plate, and the height of packing ring is used to adjust piston shoes and the free gap δ of retainer in inner groovy.
Technological scheme of the present invention is cancelled spherical block structure; The swash plate and the retainer of a new structure of design; Through a fixing packing washer piston shoes and retainer are encapsulated in the swash plate of peviform, guarantee the continuous to-and-fro motion of plunger, again through adjusting the thickness of pad; Guarantee piston shoes and the free gap of retainer in swash plate, guarantee fitting tightly of piston shoes and swash plate.Piston shoes receive the effect meeting of oil pressure and fit with swash plate, and fluid flows to the mating face from plunger center hole and piston shoes center hole, form stable oil film, are used to lubricate.
Description of drawings
Fig. 1 is the existing structural scheme of mechanism that has the cam-type axial piston pump of piston shoes
Fig. 2 is the structural scheme of mechanism that the present invention has the cam-type axial piston pump of piston shoes
Embodiment
Below will combine accompanying drawing and embodiment that technological scheme of the present invention is done to detail further:
Shown in accompanying drawing 2, this kind has the cam-type axial piston pump of piston shoes, and this plunger pump mainly comprises main shaft 1, swash plate 2, retainer 5, piston shoes 6, plunger 7, spring 8, rotor 9 and divides food tray 10; It is characterized in that: the center, inclined-plane of the swash plate 2 of retainer 5 is installed, the inner groovy 11 of a ring-type of processing, retainer 5 is a loop configuration; Processing porose 12 on the endless belt; This hole 12 is sleeved on the piston shoes 6, and piston shoes 6 and retainer 5 are arranged in this inner groovy 11, pushes down the edge of retainer 5 with packing washer 4 in the perimeter of inner groovy 11; Retainer 5 is encapsulated in the inner groovy 11; Packing washer 4 is fixed on the periphery of swash plate 2, and a packing ring 3 is set between packing washer 4 and the swash plate 2, and the height of packing ring 3 is used to adjust piston shoes 6 and the free gap δ of retainer 5 in inner groovy 11.
When main shaft 1 drove rotor 9 rotations, plunger 7 rotated with rotor 9, drove retainer 5 simultaneously and rotated, and under the effect of swash plate 2 and retainer 5, formed continuous to-and-fro motion, and fluid is inhaled into or extrudes plunger cavity through minute food tray 10, formation pressure stable oil.When plunger 7 was pressed oil, under the effect of high pressure, fluid formed film lubrication through the surface of the center hole arrival piston shoes 6 of plunger 7.
Compared with prior art, advantage of the present invention is to have cancelled spherical block and this a pair of friction pair of retainer, has reduced the wearing and tearing in the working procedure, has also reduced the difficulty of processing of retainer simultaneously, has simplified product structure.
