Description
Technical field
The invention belongs to Gear Manufacturing Technology field more particularly to a kind of Self-lubricating gears with micro- texture.
Background technology
Gear is mechanical part common in people's life, is widely used in mechanical transmission mechanism to transmit
Movement and power.Gear is driven by being intermeshed, between the flank of tooth based on sliding friction, and with rolling friction, therefore gear
Rotation be unable to do without lubrication, without enough lubrications, very big damage can be caused to gear, reduces the service life of gear.Mesh
Before, the lubricating system of gear is added to gear surface to carry out gear mostly by the way of external dressing, by lubricating oil
Lubrication, such as：Drip lubrication（Lubricating oil is dropped into friction in pairs surface）, lubrication of splashing（Lubricant is splashed to kinematic pair
Friction surface）, oil jet lubrication, flooding system lubrication etc..
The current this gear lubrication mode using external dressing, once lubricating system failure or lubricating system fluid
It is insufficient or because of other reasons, it, then can be to the tooth of insufficient lubrication when causing the operative gear in gear train not lubricated enough
Wheel causes very big damage, reduces the service life of gear；And conventional gear tooth friction interface due to high temperature between the flank of tooth, high pressure and
High sliding speed causes lubricant medium to be unable to engaging friction interface internal, and the lubricant medium of interface is often difficult to be formed lasting
Lubricating film.
Invention content
It is a primary object of the present invention to provide a kind of Self-lubricating gear with micro- texture, turn to improve existing gear
Lubricating system between dynamic can reduce Tooth friction force in the mesh tooth face processing of gear pair and the micro- of tooth surface abrasion situation knits
Structure, and using softening forms lubricating film at a high temperature of friction generates after special micro- texture filling lubricant medium, so as to fulfill
The lubricant effect of gear tooth friction regional sustained, while inhibit tooth surface abrasion and avoid using external dressing or other lubrications
Mode may caused by gear damage problem.
In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme that：
The present invention provides a kind of Self-lubricating gear with micro- texture, micro- texture includes the horizontal stroke set on gear mesh tooth face
To groove array, the lateral trench array includes the lateral trench of parallel arrangement, and the lateral trench longitudinal direction is with nibbling
It is vertical to close the flank of tooth, lubricant medium is also filled in the lateral trench, micro- texture further includes mesh tooth face in lateral trench
The outer channel with closure sideline that array periphery is equipped with, and the sideline of the outer channel Vertical Meshing gear tooth friction force direction is
Arc-shaped side, the outer fissure groove bottom are to be inclined to the slope surface of the lateral trench.
As the present invention to the preferred of said program, the outer channel width dimensions are between 15~30 μm, the transverse direction
Groove width size is between 10~15 μm.
As the present invention to the preferred of said program, the lateral trench quantity is 4~16.The quantity of lateral trench can
With the face width of tooth and the width design of lateral trench according to gear, there is larger selectivity.
As the present invention to the preferred of said program, the mesh tooth face of the gear is equipped at two or the above is micro- at two
Texture.By setting micro- texture described in many places that can further promote the friction reducing effect of the flank of tooth.
As the present invention to the preferred of said program, the lubricant medium is solid lubrication medium.
As the present invention to the preferred of said program, the solid lubrication medium is micro- MoS2Micro mist.
The beneficial effects of the present invention are：
（1）Heretofore described micro- texture includes the outer channel of lateral trench array and lateral trench array periphery, first laterally
Groove array stores solid lubrication medium at gear tooth friction interface using lateral trench, can be in the environment of flank of tooth severe friction
Under long lasting for supply lubricant medium, be conducive to the lasting formation of lubricating film, so as to improve lubricant effect, reduce friction, together
When the role of container can be served as due to the presence of flank of tooth lateral trench, lateral trench, it is small that storage flank of tooth metal can be collected
Particle, conducive to gear tooth friction abrasion is reduced；
（2）The fluid lubrication media for forming lubricating film can be concentrated and be back to flank of tooth lateral trench battle array by outer channel in the present invention
At row, so as to make the process of lubrication more longlasting, the consumption of lubricant medium can be also reduced, due to that can be generated perhaps during gear tooth friction
Multiple tooth face glue, outer channel equally can store the metal molecule of flank of tooth generation such as lateral trench array, conducive to reduction
Gear tooth friction is worn；
（3）Under prior art middle gear long-term work, as flank of tooth glue increases, flank of tooth glue is readily along frictional force side
To accumulation, so as to cause to be difficult to the buildup cleared up, and the effect of lubrication is reduced, the harm of abrasion is brought to the flank of tooth.Due to
The flank of tooth glue particle that the flank of tooth generates is perpendicular to what lateral trench direction in the present invention was flowed, and flank of tooth glue has been not easy
All standing lateral trench texture, lubricant medium lubricating film can be carried out continuing supplement by lateral trench, can improve gear and nibble
Close the frictional behaviour during transmission process；
（4）The sideline of groove vertical mesh tooth face direction in China and foreign countries' of the present invention is arc-shaped side, makes small using arc-shaped side
Grain is flowed with the lubricant medium of fluid state, so as to which outer channel is also difficult to generate flank of tooth glue into without forming buildup, from
And enable micro- texture in the present invention that there is preferable using effect.
Therefore, micro- texture self-lubricating gear of the present invention not only has preferable lubrication and friction reducing effect, also has
There is the advantages of saving lubricant medium, service life is long, lubricant effect is good.
