Description
Technical field
The present invention relates 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.
The content of the invention
The goal of the invention of the present invention be to overcome now the cogged gear teeth lack lubricating oil and easily cause mesh regional abrasion, reduction
Service life, the lubricant effect above-mentioned deficiency such as not good there is provided a kind of new internal Self-lubricating gear, during gear drive from
Row release saves lubricating oil to tooth surface, effectively slows down the abrasion of the gear teeth, reduces use cost, increases the service life.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of new internal Self-lubricating gear, comprising several gear teeth, is provided with cavity, each gear teeth in each gear teeth
Region of engagement be provided with several holes one, the body be provided with least one hole two, the Kong Yiyu holes two with the sky
Chamber is connected, and the hole two is provided with check valve.
Using a kind of new internal Self-lubricating gear of the present invention, comprising several gear teeth, it is provided with each gear teeth
Cavity, the cavity is used to store lubricating oil, and the region of engagement of each gear teeth, which is provided with several holes one, the body, to be set
There is at least one hole two, the Kong Yiyu holes two are connected with the cavity, the hole two is provided with check valve, the cavity
Interior to be full of lubricating oil, the lubricating oil that the check valve is limited in the cavity flows out from the Kong Erzhong, keeps in the cavity
Lubricating oil is stored, the hole one is distributed in the region of engagement of the gear teeth, because the gear is persistently rotated, in centrifugal force, again
In the presence of power, the lubricating oil is from Kong Yizhong outflows coating to the region of engagement of the gear teeth so that the region of engagement energy
It is enough automatically, constantly to be lubricated, chemical films are formed, so as to protect tooth surface, reduce the abrasion of gear, using present apparatus energy
Enough region of engagements that is automatic, constantly lubricating the gear teeth, improve lubricant effect, regions of lubrication extensively, reduces the abrasion of the gear teeth, extends tooth
The service life of wheel, improves the reliability and security of working gear, solves the gear inconvenient peace for adding lubricating oil at work
Full sex chromosome mosaicism, reduces the waste of lubricating oil, it is to avoid oil bath mode causes the leakage of lubricating oil, saves cost, simple in construction, processing
It is convenient, the Large Reducer for the low speed heavy load that is particularly suitable for use in.
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 invention are as follows：
1st, using a kind of new internal Self-lubricating gear of the present invention, the region of engagement of the gear teeth can automatically, be constantly lubricated, is improved
Lubricant effect, regions of lubrication extensively, reduces the abrasion of the gear teeth, extends the service life of gear, improves the reliability of working gear
And security, the gear inconvenient safety issue for adding lubricating oil at work is solved, the waste of lubricating oil is reduced, it is to avoid oil bath
Mode causes the leakage of lubricating oil, saves cost, simple in construction, easy to process, the large-scale of low speed heavy load that be particularly suitable for use in subtracts
Fast device.
2nd, using a kind of new internal Self-lubricating gear of the present invention, fuel-displaced oil circuit is shorter, fuel-displaced quick, can avoid
Rotate to the fuel-displaced influence brought, lubricant effect more preferably, is easy to contact with lubricating oil, enter preferably lubricating oil described
Cavity.
3rd, using a kind of new internal Self-lubricating gear of the present invention, it is to avoid side is strong where the influence region of engagement
Degree.
