Technical field
The utility model relates to a kind of plunger hydraulic pump component, and in particular, the utility model relates generally to a kind of variable swash plate for hydraulic planger pump.
Background technique
The hydraulic plunger pump structure is designed by German BOSCH-REXROTH company the earliest, in the using process of long-term real work, its variable swash plate easily produces premature wear in a side of bearing high pressure, and wearing and tearing concentrate on slide rail and the thrust surface of this side, and its structure is demanded urgently improving.be particularly that the aforementioned premature wear phenomenon of oil hydraulic pump of A10VO28 is obvious especially for model, and hydraulic planger pump is used to constant-voltage system at present widely, system for frequent commutation, the friction pair between piston shoes and thrust surface of this pump need enough lubricated, on high-tension side slide rail also must have lubricated fully, effectively increase the area of contact of slide rail, and supply enough lubricant oil, can improve performance, and the under-supply problem of the above-mentioned lubricant oil of existing structure ubiquity of these type of oil hydraulic pump part component, therefore be necessary its structure is made further improvement.
Summary of the invention
One of the purpose of this utility model is to solve above-mentioned deficiency, and a kind of variable swash plate for hydraulic planger pump is provided, and solves in prior art the variable swash plate with expectation and surveys at high pressure that to be prone to lubricant oil under-supply, thereby the technical problem such as premature wear occurs.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of variable swash plate for hydraulic planger pump provided by the utility model, comprise the swash plate body, the upper end of described swash plate body is provided with thrust surface, the lower end is provided with the circular arc supporting, also be provided with lubrication hole on described swash plate body, also be provided with slide rail on the side of described swash plate body lower end, and slide rail be provided with at least two Lubricating oil storage grooves, be provided with supporting surface between described at least two Lubricating oil storage grooves, and be connected with lubrication hole by lubrication channel respectively.
As preferably, further technological scheme is: the left and right sides of described swash plate body lower end is equipped with slide rail, and wherein the slide rail of a side is provided with at least two Lubricating oil storage grooves.
Further technological scheme is: also be provided with at least two installation screws on described swash plate body.
compared with prior art, one of the beneficial effects of the utility model are: by on the slide rail that bears high pressure one side at variable swash plate body, two or more Lubricating oil storage grooves being set, and be connected with lubrication hole respectively, make two or more Lubricating oil storage grooves whiles to this side supplying lubricating oil and form oil film, guaranteed the lubricated amount between variable swash plate high pressure side slide rail and casing of hydraulic pump upper support brasses, and the apart section between two Lubricating oil storage grooves is as supporting surface, significantly improved the mechanical friction between them, avoid premature wear, a kind of variable oblique disk structure for hydraulic planger pump provided by the utility model is simple simultaneously, be suitable for installing and using in various plunger hydraulic pumps, application area is wide.
Description of drawings
Fig. 1 is for being used for an embodiment's of explanation the utility model structural representation;
Fig. 2 is for being used for another embodiment's of explanation the utility model installment state schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
With reference to figure 1, shown in Figure 2, an embodiment of the present utility model is a kind of variable swash plate for hydraulic planger pump, comprise the swash plate body, the upper end of described swash plate body is provided with thrust surface 1, the lower end is provided with circular arc supporting 2, also be provided with lubrication hole 3 on described swash plate body, also be provided with slide rail 4 on the side of described swash plate body lower end, and slide rail 4 is provided with at least two Lubricating oil storage grooves 5, be provided with supporting surface 8 between described at least two Lubricating oil storage grooves 5, and be connected with lubrication hole 3 by lubrication channel 6 respectively.And in the present embodiment, the concrete quantity of above-mentioned Lubricating oil storage groove 5 can be according to actual use condition, and required lubricated amount arranges arbitrarily.
Again with reference to shown in Figure 1, a preferred embodiment that is used for the technical solution problem at the utility model, can slide rail 4 all be set in the left and right sides of above-mentioned swash plate body lower end, and wherein the slide rail 4 of a side is provided with at least two Lubricating oil storage grooves 5, and opposite side keeps standing state that a Lubricating oil storage groove 5 is set, and also is connected with lubrication hole 3 by lubrication channel 6.
Simultaneously, for convenience of the installation of swash plate in hydraulic planger pump, the inventor also sets up two installation screws 7 with reference to prior art on above-mentioned swash plate body.
Again as shown in Figure 1 and Figure 2, the utility model is a kind of hydraulic planger pump variable swash plate, described variable swash plate is an individual component, its thrust surface and plunger piston slippery boots opposite planar are slided and are formed friction pair, the bottom of variable swash plate is circular arc, as swinging sliding bearing, with the supporting brasses formation friction pair on housing.Lubricating oil storage groove 5 in figure uses mould to make when cast blank, and is that lubrication channel 6 processes by auxiliary hole.In actual use, when plunger pump was in high pressure conditions, pressure oil entered Lubricating oil storage groove 5 from lubrication hole 3, located to form oil film between slide rail 4 and brasses, and is lubricated as the motion of variable swash plate; Simultaneously, when plunger piston slippery boots carried out revolution motion on swash plate, because plunger is subject to high pressure, piston shoes can compress thrust surface, thereby compressed slide rail, and making between slide rail and brasses to have enough supporting surfaces and lubricant film; Our improved design is exactly on the basis of original design, has increased bearing area and has strengthened lubricants capacity, makes the rear variable swash plate of improvement more flexible, more durable.Reached the slide rail of protection variable swash plate not by the purpose of premature wear.
