Self-lubricating internal gear with centrifugal stripper plateTechnical field
The present invention relates to a kind of self-lubricating internal gear, a kind of profit certainly with centrifugal stripper plateSliding internal gear.
Background technology
Prior art has more Self-lubricating gear, but these Self-lubricating gears are external gear mostly, energyEnough utilize centrifugal action, will be located in the lubricating oil in the middle part of gear and get rid of to teeth position, thus reach self-lubricatingEffect.But the center being because internal gear is not easy to install the container holding lubricating oil, the outer surface of internal gearInstall and be not easy to again utilize centrifugal force to be got rid of in teeth, prior art by lubricating oil after holding the container of lubricating oilThe most not there is the internal gear of self-lubricating function.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of with stripper plateAnd oil storing tube, the lubricating oil in oil storing tube can be pressed to teeth by stripper plate under the influence of centrifugal force, thusReach the self-lubricating internal gear with centrifugal stripper plate of the effect of self-lubricating.
The present invention solves the technical problem in the presence of prior art by following technical proposals:
A kind of self-lubricating internal gear with centrifugal stripper plate, including an internal gear body, described internal gearOffering teeth on the inner surface of body, the described internal gear with self-lubricating structure also includes an oil storing tube,A " V " shape groove, the end of described " V " shape groove is offered on the outer surface of described internal gear bodyPortion offers oil guiding hole, and the other end of described oil guiding hole is opened on the inner surface of described internal gear body；The cirque structure that described oil storing tube is made up of the elastomeric material of tubulose, is stored with lubricating oil；DescribedOil storing tube inner surface on be evenly arranged multiple oil outlet, described oil storing tube is arranged in described " V "In shape groove, described oil outlet is connected with described oil guiding hole；The outer surface of described internal gear bodyOn be provided with multipair stripper plate, one end of described stripper plate is hinged with described internal gear body, the other endBeing provided with balancing weight, every pair of described stripper plate is arranged in the both sides of described " V " shape groove and distance is less thanThe diameter of the cross section of described oil storing tube.
As preferred embodiment of the present invention, the other end of described oil guiding hole is opened in the table of described teethFace.
As preferred embodiment of the present invention, the other end of described oil guiding hole is opened in nibbling of described teethOn conjunction face.
The advantage with the self-lubricating internal gear of centrifugal stripper plate of the present invention is: with stripper plate and oil storing tube,Lubricating oil in oil storing tube can be pressed to teeth by stripper plate under the influence of centrifugal force, thus reaches self-lubricatingEffect.

Detailed description of the invention
Below the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be moreIt is prone to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite boundaryFixed.
The advantage with the self-lubricating internal gear of centrifugal stripper plate of the present invention is: with stripper plate and oil storing tube,Lubricating oil in oil storing tube can be pressed to teeth by stripper plate under the influence of centrifugal force, thus reaches self-lubricatingEffect.
As shown in Figure 1 and Figure 2, a kind of self-lubricating internal gear with centrifugal stripper plate, including an internal gear originallyBody 1 and an oil storing tube 2,
As shown in Figure 3, Figure 4, the inner surface of this internal gear body 1 offers teeth, this internal gear bodyOffering a " V " shape groove 11 on the outer surface of 1, the bottom of this " V " shape groove 11 offers oil guiding hole12, the other end of this oil guiding hole 12 is opened on the inner surface of this internal gear body 1；This internal gear body 1Outer surface on be provided with multipair stripper plate 13, one end of this stripper plate 13 is hinged with this internal gear body 1,The other end is provided with balancing weight 131；
As it is shown in figure 5, the cirque structure that this oil storing tube 2 is made up of the elastomeric material of tubulose, its internal memoryContain lubricating oil；Multiple oil outlet 21 it has been evenly arranged, this oil storing tube 2 cloth on the inner surface of this oil storing tube 2Putting in this " V " shape groove 11, this oil outlet 21 is connected with this oil guiding hole 12；
As shown in Figure 1 and Figure 2, this every pair stripper plate 13 be arranged in this " V " shape groove 11 both sides and away fromDiameter from the cross section less than this oil storing tube 2.When this internal gear body 1 rotates, every pair of stripper plate 13The oil storing tube 2 of centre can be pressed under the influence of centrifugal force, thus by the pounding out of lubricant in oil storing tube 2And flow to teeth along this oil outlet 21 and oil guiding hole 12, reach the purpose of self-lubricating.
The other end of this oil guiding hole 12 is opened in the surface of these teeth.The lubricating oil on internal gear teeth surface fromFlowing in teeth groove can be increasingly towards under the effect of mental and physical efforts, the oil outlet of this oil guiding hole 12 is opened in these teethSurface is conducive to lubricating whole teeth.
The other end of this oil guiding hole 12 is opened on the field of conjugate action of these teeth.Can also be anti-for i.e. rotating forwardThe internal gear body 1 turned, no matter this oil guiding hole 12 is opened on which face of teeth, all can reach preferably to moistenSliding effect, but for the internal gear body rotated the most in one direction, this oil guiding hole 12 is opened in and nibblesOn conjunction face, also help the gear that lubrication is meshed with this internal gear body 1.
It is only more than the mentality of designing of the some embodiments of the present invention, in the case of system allows, thisInvention can expand to the most external more functional module, thus extends its function to greatest extent.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited toThis, any change expected without creative work or replacement, all should contain in protection scope of the present inventionWithin.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
