Description
Technical field
The utility model is related to technical field of mechanical transmission, particularly a kind of new internal Self-lubricating gear.
Background technology
Gear is the medium being driven between machinery, gear mechanism to transmit two axles between motion and power, be not Tongfang
The transmission of position kinetic energy is there is provided possible, because gear-driven efficiency is high, and accurately, service life is long, safe and reliable for gearratio,
Therefore gear drive equipment is widely used in all trades and professions, and its type and size are varied, it is necessary to the application requirement met
It is different, but gear, as one of key components and parts of various drive apparatus, its performance quality is direct to a certain extent
Determine the service life of whole equipment.
During the use of decelerator, the engagement between gear is relied primarily on, and the coefficient of friction between meshing gear is larger,
If lacking lubricating oil, also easily heating is damaged between frequent meshed gears, especially the Large Reducer of low speed heavy load, mill
Damage more serious, it is therefore desirable to lubricating oil periodically is added to gear pair, otherwise the gear geometric features after heavy wear change
Become, backlash increase causes strength of gear teeth step-down, gearing noise to become big, transmission is unstable, or even can cause the safety of broken teeth
Accident.And when adding lubricating oil, the mode according to cast pours lubricating oil in tooth surface, in this process, greatly
Parts of lubricating oil can not be covered in the surface of the gear teeth for a long time, cause very big waste, and lubricant effect is not good；And use oil bath
Mode sets grease-box in gear-box, stores more lubricating oil, gear frictional heating causes the temperature inside the box to raise, with the external world
Pressure differential increase, lubricating oil easily causes oil leak under differential pressure action.
Utility model content
Goal of the invention of the present utility model be to overcome now the cogged gear teeth lack lubricating oil and easily cause mesh regional
Abrasion, reduces service life, and lubricant effect is not good etc. above-mentioned not enough there is provided a kind of new internal Self-lubricating gear, is passed in gear
Voluntarily discharged during dynamic to tooth surface, save lubricating oil, effectively slow down the abrasion of the gear teeth, reduce use cost, extension makes
Use the life-span.
To achieve these goals, the technical solution adopted in the utility model is：

It is preferred that, each gear teeth are provided with a hole two.
I.e. each hole two is correspondingly arranged on the gear teeth, and fuel-displaced oil circuit is shorter, fuel-displaced quick, can be avoided
Rotate to the fuel-displaced influence brought, lubricant effect more preferably, is easy to contact with lubricating oil, enter preferably lubricating oil described
Cavity.
It is preferred that, the hole two is located at the non-region of engagement of the wheel flank.
The hole two is located at the non-region of engagement of the gear teeth, that is, is not involved in the side of engagement, it is to avoid the influence region of engagement
The intensity of place side.
It is preferred that, all holes two are located at the homonymy of each gear teeth.
It is preferred that, all holes one are located at the side of rotation direction on the region of engagement.
For operative gear structure, such as reduction box, the rotation direction of gear remains constant, all holes
One is located at the side of rotation direction on the region of engagement, is conducive to saving processing cost, it is to avoid waste lubricating oil.
It is preferred that, the Kong Yiyu holes two are circle, and the diameter in the hole one is less than the diameter in the hole two.
It is further preferred that the 1/25-1/15 of the width in place face on a diameter of gear teeth in the hole one.
It is further preferred that the 1/3-1/2 of the width in place face on a diameter of gear teeth in the hole two.
It is preferred that, all Kong Yizhong are provided with penetrant, and the penetrant is sponge.
Penetrant is set in the Kong Yizhong, the lubricating oil can be made slowly uniformly to flow out, lubricant effect is more preferable.
It is further preferred that the oil outlet end in all holes one is provided with protection network.
The protection network is used to limit the penetrant, it is to avoid it departs from from the Kong Yizhong, while not influenceing its fuel-displaced.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, using a kind of new internal Self-lubricating gear of the present utility model, nibbling for the gear teeth can automatically, be constantly lubricated
Area is closed, lubricant effect is improved, regions of lubrication extensively, reduces the abrasion of the gear teeth, extends the service life of gear, improves working gear
Reliability and security, solve gear at work inconvenience addition lubricating oil safety issue, reduce lubricating oil waste,
Avoid oil bath mode from causing the leakage of lubricating oil, save cost, simple in construction, easy to process, be particularly suitable for use in low speed heavy load
Large Reducer.
2nd, using a kind of new internal Self-lubricating gear of the present utility model, fuel-displaced oil circuit is shorter, fuel-displaced quick, can
Avoid rotating to the fuel-displaced influence brought, lubricant effect more preferably, is easy to contact with lubricating oil, preferably can enter lubricating oil
The cavity.
