Abstract
It is used the invention discloses one kind and rubs and roll compound action, effectively extend the plunger pump variable swash plate seat in the service life of swash plate runway, the swash plate seat rubbing surface is equipped with the roller groove with swash plate seat cancave cambered surface identical radian measure, it is placed with idler wheel in the roller groove, by the movement for the immixture mechanism support swash plate seat for rubbing and rolling.
Description
Technical field
The invention belongs to the plunger pump variable swash plate seats of a kind of friction and rolling compound action.
Background technique
In hydraulic pump field, existing oblique disk structure is all made of to be supported by two semi-circular runways as shown in Figure 1, and hydraulic
The pressure of medium acts on plunger, is transmitted on swash plate by piston shoes.Pressure has several tons here in huge discharge plunger pump,
This power is ultimately applied on the semicircle runway of support swash plate.In addition to certain high pressure encloseds are pumped using half-moon-shaped bearing support,
Swash plate runway generallys use friction mode.
Huge action of hydraulic force is transmitted on swash plate runway on swash plate, will form rubbing for strength when variable occurs
It wipes, over time, forms serious abrasion on runway, cannot achieve smoothly variable when serious.In order to delay to wear, city
Plunger pump product on field uses wear resistance, such as improves surface hardness, laser quenching, seeps nickel, boronising etc..
Summary of the invention
The technical problem to be solved in the present invention is to provide it is a kind of friction and rolling compound action plunger pump variable swash plate seat,
It uses friction and rolls compound action mechanism, effectively extends the service life of swash plate runway.
To solve the above problems, the present invention adopts the following technical scheme:
A kind of plunger pump variable swash plate seat of friction and rolling compound action, the swash plate seat rubbing surface is equipped with and swash plate
The roller groove of seat cancave cambered surface identical radian measure, is placed with idler wheel in the roller groove, by the immixture mechanism branch for rubbing and rolling
Support the movement of swash plate seat.
Further technical solution is that the idler wheel is at least placed with two or more.
Further technical solution is that idler wheel retainer is also placed in the roller groove, idler wheel retainer be equipped with
The placing groove of idler wheel cooperation makes idler wheel keep defined distance not send out mutually between roller axis when rolling in roller groove
Raw collision.
Further technical solution is that swash plate seat center is equipped with drive shaft hole, and the position setting of the roller groove exists
On rubbing surface, it is located proximate to drive shaft hole side or far from drive shaft hole side or the middle position in rubbing surface.
The beneficial effects of the present invention are:, when scraping mechanism plays a role, scroll mechanism not yet acts as in the initial stage
With with the generation of friction surface wear, idler wheel starts between swash plate gradually by slightly contacting with each other to practical, holds at this
Continue it is longer during, friction and roll two kinds of mechanism mutually act on simultaneously, rolling support facilitate alleviation surface abrasion into
The support of journey, rubbing surface alleviates the load acted on idler wheel again, and the two complements each other, and effectively extends the use of swash plate runway
Service life.

Specific embodiment
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to FIG. 1 to 6, the plunger pump variable swash plate seat of a kind of friction and rolling compound action, the swash plate seat 2
Rubbing surface is equipped with the roller groove 1 with 2 cancave cambered surface identical radian measure of swash plate seat, idler wheel 4 is placed in the roller groove 1, by rubbing
With the movement of the immixture mechanism support swash plate seat 2 of rolling.
4 quantity of idler wheel is generally at least placed with two or more depending on structure space and load.
Idler wheel retainer 3 is also placed in the roller groove 1, idler wheel retainer 3 is equipped with the placement cooperated with idler wheel 4
Slot makes idler wheel 4 keep defined distance not collide mutually between roller axis when rolling in roller groove 1.
2 center of swash plate seat is equipped with the drive shaft hole 7 by drive shaft, and the position setting of the roller groove 1 is rubbing
On face, it is located proximate to 7 side of drive shaft hole or far from 7 side of drive shaft hole or the middle position in rubbing surface.
In the present embodiment, as shown in Fig. 2, according to the tolerance of setting, in the initial stage, idler wheel 4 is not contacted with swash plate, tiltedly
Disk is directly contacted with swash plate seat 2, and movement at this time is scraping mechanism, when being worn to a certain extent between swash plate seat 2 and swash plate,
With the increase of abrasion, idler wheel starts to continue gradually by slightly contacting with each other to practical in this process between swash plate
In longer time, the supporting role of idler wheel 4 gradually plays a role, and the supporting role of idler wheel 4 alleviates mill to a certain extent
Damage process.After the abrasion of idler wheel 4 or roller groove 1 are recessed, rubbing surface becomes primary friction support once again, so alternately, even if
Idler wheel 4 fails (abrasion or damaged), and rubbing surface remains to continue to work until that big arrive of abrasion can not normal variable.In addition, 1 material of roller groove
Matter hardness is lower than idler wheel 4, and by the long-term roll-in of idler wheel 4, small recess can occur for the surface of roller groove 1, this degree
Recess helps to promote certain scraping mechanism to occur in the stage that idler wheel mechanism works, and facilitates the alternating work of two kinds of mechanism
Make.
As shown in figure 4, idler wheel 4 can also be designed to and swash plate and swash plate in the initial stage according to different load condition
The friction surface of seat directly contacts, and so that friction and rolling double mechanism is told in the initial stage in this way.
Wherein, the quantity of idler wheel 4 can at least place two or more, as shown in figure 4, roller groove 1 depending on actual load
It is inside additionally provided with a holding rack slot 6, idler wheel retainer 3, which is placed on, to be kept keeping relatively defined distance phase to idler wheel 4 in rack slot 6
It does not collide between mutually.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work should all be covered in the scope of the present invention.
