Self-lubricating internal gear with oil storage end capTechnical field
This utility model relates to a kind of self-lubricating internal gear, in a kind of self-lubricating with oil storage end capGear.
Background technology
Prior art has more Self-lubricating gear, but these Self-lubricating gears are external gear mostly, it is possible to utilizeCentrifugal action, will be located in the lubricating oil in the middle part of gear and gets rid of to teeth position, thus reach the effect of self-lubricating.But it is because internal toothThe center of wheel is not easy to install the container holding lubricating oil, and the outer surface of internal gear installs inconvenience again after the container holding lubricating oilThe most not there is in teeth, prior art the internal gear of self-lubricating function in utilizing centrifugal force to be got rid of by lubricating oil.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides a kind of with oil storage endLid, the end face that end cap is connected with internal gear body offers oil outlet, it is possible to penetrate lubrication under the influence of centrifugal forceOil, reaches the self-lubricating internal gear with oil storage end cap of the effect of self-lubricating.
This utility model solves the technical problem in the presence of prior art by following technical proposals:
A kind of self-lubricating internal gear with oil storage end cap, including an internal gear body, described internal gear body interiorOffering teeth on surface, the described internal gear with self-lubricating structure also includes an oil storage end cap, described oil storage end capFor discoidal hollow structure, hollow structure is filled with lubricating oil, an end face of described oil storage end cap offers fuel-displacedHole, described oil outlet is near described teeth layout, an end face of described oil storage end cap and described internal gear bodyAn end face be connected.
As this utility model preferred embodiment, the outer surface of described internal gear body offers external screw thread, instituteFemale thread circle, described female thread circle and described internal gear body screw thread it is additionally provided with on one end face of the oil storage end cap statedConnect.
As this utility model preferred embodiment, described oil outlet is arranged in the position on the top of described teethPut.
Advantage with the self-lubricating internal gear of oil storage end cap of the present utility model is: with oil storage end cap, on end cap withOffer oil outlet on the end face that internal gear body is connected, it is possible to penetrate lubricating oil under the influence of centrifugal force, reach from moisteningSliding effect.

Detailed description of the invention
Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energyIt is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Advantage with the self-lubricating internal gear of oil storage end cap of the present utility model is: with oil storage end cap, on end cap withOffer oil outlet on the end face that internal gear body is connected, it is possible to penetrate lubricating oil under the influence of centrifugal force, reach from moisteningSliding effect.
Embodiment one:
As it is shown in figure 1, a kind of self-lubricating internal gear with oil storage end cap, including internal gear body 1 and an oil storage endLid 2；
As it is shown in figure 1, offer teeth 11 on the inner surface of this internal gear body 1；
As shown in Figure 2 and Figure 3, this oil storage end cap 2 is discoidal hollow structure, and hollow structure is filled with lubricating oil, this storageOffering oil outlet 21 on one end face of oil end cap 2, this oil outlet 21 is arranged near these teeth 11, the one of this oil storage end cap 2Individual end face is connected with an end face of this internal gear body 1.
When this is with the self-lubricating internal gear rotation of oil storage end cap, the lubricating oil in this oil storage end cap 2 can be centrifugalTowards surrounding motion and produce certain pressure in the position away from this oil storage end cap 2 center under the effect of power, thus lubricating oilCan this with oil storage end cap self-lubricating internal gear rotate time from this oil outlet 21 directive teeth 11, reach self-lubricatingPurpose.
Embodiment two:
On the basis of embodiment one, as shown in Figure 2 and Figure 3, the outer surface of this internal gear body 1 offers external screw thread,Being additionally provided with female thread circle 22 on one end face of this oil storage end cap 2, this female thread circle 22 is with this internal gear body 1 screw thread evenConnect.This structure is conducive to this oil storage end cap 2 of fast quick-detach, use more convenient fast.
Embodiment three:
On the basis of embodiment one or two, as Figure 1 and Figure 4, this oil outlet 21 is arranged in the top of these teeth 11The position of end.It is positioned at the top of teeth 11 after lubricating oil injection, along with the rotation of this internal gear body 1, gets final product uniform fold extremelyWhole teeth 11, lubricant effect is more preferably.
It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this realityThe most external more functional module can be expanded to novel, thus extend its function to greatest extent.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit toIn this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
