Description
Technical field
This utility model relates to a kind of internal gear, and a kind of inside is with the internal gear of oil pumping device.
Background technology
Prior art has more Self-lubricating gear, but these Self-lubricating gears are external gear mostly, it is possible to utilize
Centrifugal 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 tooth
The 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 oil
The 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 inside one with oil
Cylinder, has lubricating oil and plunger in oil cylinder, along with the rotation of gear, the centrifugal force produced due to plunger more than lubricating oil produce from
Mental and physical efforts, therefore lubricating oil can be pumped out to teeth position by plunger by oil outlet, reach self-lubricating effect inside with
The internal gear of oil pumping device.
This utility model solves the technical problem in the presence of prior art by following technical proposals:
A kind of inside, with the internal gear of oil pumping device, its inner surface is provided with teeth, the inside of described internal gear
Be provided with multiple oil cylinder, the central shaft of described oil cylinder along described inside with the radial arrangement of the internal gear of oil pumping device,
Being contained with lubricating oil in described oil cylinder, the front end of described oil cylinder is connected with one end of an oil outlet, rear end and an air inlet
The one end in hole is connected, and is also placed with a plunger in described oil cylinder, described lubricating oil level in the front side of described plunger, institute
The oil outlet stated and the other end of described air inlet are opened in the described inside inner surface with the internal gear of oil pumping device
On.
As this utility model preferred embodiment, the other end of described oil outlet and described air inlet is opened in institute
The top of the teeth stated.
As this utility model preferred embodiment, the lower section of each teeth is provided with two oil cylinders, and each teeth are opened
Being provided with an oil outlet and two air inlets, described oil outlet is arranged in the center of described teeth, and two air inlets are arranged
Both sides at described oil outlet.
Inside of the present utility model with the advantage of the internal gear of oil pumping device is: internal with oil cylinder, has profit in oil cylinder
Lubricating oil and plunger, along with the rotation of gear, the centrifugal force produced due to plunger is more than the centrifugal force that lubricating oil produces, therefore plunger
Lubricating oil can be pumped out to teeth position by oil outlet, reach the effect of self-lubricating.

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 energy
It 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.
Inside of the present utility model with the advantage of the internal gear of oil pumping device is: internal with oil cylinder, has profit in oil cylinder
Lubricating oil and plunger, along with the rotation of gear, the centrifugal force produced due to plunger is more than the centrifugal force that lubricating oil produces, therefore plunger
Lubricating oil can be pumped out to teeth position by oil outlet, reach the effect of self-lubricating.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of inside, with the internal gear of oil pumping device, its inner surface is provided with teeth 1,
This internal gear be internally provided with multiple oil cylinder 2, the central shaft of this oil cylinder 2 is along the footpath of internal gear with oil pumping device inside this
To layout, being contained with lubricating oil in this oil cylinder 2, the front end of this oil cylinder 2 is connected with one end of an oil outlet 3, rear end is entered with one
One end of pore 4 is connected, and (front end alleged in this utility model refers to inside this internal gear with oil pumping device
One end, center, rear end refers near its one end, center), also it being placed with a plunger 5 in this oil cylinder 2, this lubricating oil level is in this plunger 5
Front side, the other end of this oil outlet 3 and this air inlet 4 is opened in the inner surface of the internal gear inside this with oil pumping device
On.Plunger generally has steel to make, and its density is much larger than the density of lubricating oil, therefore with the internal tooth of oil pumping device inside this
When wheel rotates, the centrifugal force that the centrifugal force that plunger produces produces also much larger than lubricating oil, therefore, it is possible to lubricating oil is fuel-displaced along this
Hole 3 pumps out, and inside this, rotating speed of internal gear with oil pumping device is the fastest, and the centrifugal force of generation is the biggest, and lubricating oil is by pump
The speed gone out is the fastest.This air inlet 4 is prevented from the tail end of this plunger 5 and produces negative pressure.
As shown in Figure 2 and Figure 3, the other end of this oil outlet 3 and this air inlet 4 is opened in the top of these teeth 1.Internal gear
The lubricating oil of upper tooth surface can flow, by favourable for the top that oil outlet 4 is opened in teeth 1 under the action of the centrifugal in teeth groove
In lubricating whole teeth 1, the top that air inlet 4 is opened in teeth 1 can also avoid this air inlet 4 to be blocked by dirt.
The lower section of each teeth 1 is provided with two oil cylinders 2, and each teeth 1 offer an oil outlet 3 and two air inlets
Hole 4, this oil outlet 3 is arranged in the center of these teeth 1, and two air inlets 4 are arranged in the both sides of this oil outlet 3.This structure makes
Inside this, the weight with the two ends, left and right of the internal gear of oil pumping device more equalizes, it is possible to increase with oil pumping device inside this
Internal gear run stability.
It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this reality
The 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 to
In 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.
