Description
Technical field
The present invention relates to a kind of machine power transmission part more particularly to a kind of gear by process of surface treatment,
It is related to a kind of process being surface-treated to gear, is further directed to the equipment being surface-treated to gear.
Background technology
Gear is a kind of most common machine power transmission part, is revolved for the mechanical engagement similar with another with transmitting
Transhipment is dynamic.Common gear has planetary gear, spur gear, bevel gear, turbine etc..Gear transmission is most common transmission in machinery
One of mode is widely used in the industry such as communications and transportation, machine-building and the fields such as civilian.
When gear engagement is transmitted, due to there is opposite slip on the field of conjugate action, force of sliding friction is generated between the field of conjugate action.It rubs
Wiping the change of the size and Orientation of power causes to generate meshing impact in Meshing Process of Spur Gear so that gear generates fatigue and abrasion
It destroys.
The research to improving gear fatigue and wear-out failure is carried out in the prior art, it is proposed that some were solved does
Method.
If Chinese patent CN102384243A discloses a kind of gear, outer teeth are set on gear mass, outer teeth with outside
Tooth socket separately, is provided with endoporus among gear mass, endoporus is circumferentially uniformly provided with internal spline, and interior hole end surface is equipped with multiple oilholes,
It is communicated by the oil duct that oilhole is formed with outer teeth groove and internal spline, nickel coating is covered on gear mass surface.But the gear in the patent
It needs to open up aperture on end face and gear mass, production and processing difficulty is very big, and if is bored after nickel coating is formed
Hole is easy to cause coating and is destroyed, and if drilling nickel plating again later, and be easy to cause oilhole blocking, therefore the patent is difficult to
Efficiently produce qualified gear.
Although for another example Chinese patent CN103697142A is further improved on this basis again, gear is divided into two
A half wheel part, when being needed replacing after abrasion, directly changes gear.But the improvement of the program only for repair more
It changes and carries out, the difficulty of production and processing is not still overcome.
For another example Chinese patent CN103511590A discloses a kind of dung beetle surface structure bionic gear, and gear mass is equipped with outer
Teeth and outer teeth groove, the outer teeth and outer teeth groove are separately, it is characterised in that：It is provided with not on the surface of the outer teeth
An only spheroid.Using even column spheroid and odd column spheroid interlaced arrangement mode, frictional force can be reduced and improve antifatigue energy
Power.But the patent does not disclose how surface texture as the formation of convenience and high-efficiency, and simultaneously if at using surface
The reason technology such as processing methods such as Laser surface heat treatment, roll flute finishing are easy to cause material surface breakage again, and there are larger
Residual stress makes gear accelerate the degree of damage at work.
In addition increase the wearability of gear using the method for face coat, if mentioned above cross uses nickel coating in patent,
But the raising of wear-resisting property is directly related with coating, the thickness of coating is very limited, once therefore coating abrasion after,
The just rapid reduction of the service life of gear.
It is reported that, Gifu, Japan university mold is created into Technical Research Center and Central Fine Tool in recent years
(general headquarters of company：Gifu Prefecture, Japan Hui Na cities) joint development gone out using carbon fibre fabric strengthen plastic gear.Pass through reality
Using this gear, the metal gear of the outfits such as automobile is substituted, is expected to realize lightweight, production cost is reduced and extends the product longevity
Life.Researcher reduces tensile stress by adding in carbon fiber in gear, extends gear life (Fig. 3).Extensively should
For the fields such as aircraft carbon fiber enhancement resin base composite material (CFRP) although the characteristics of having light weight and high intensity,
But since difficulty of processing is larger, it is also not used to the mass production of mechanical part at present.If utilize this gear newly developed
On the technique that uses, can need to use carbon fiber on the manufacture object of mass production in auto parts and components etc..But it also lacks at present
Weary manufacture cost and product strength to plastic gear specifically and is fully verified, especially for the tooth of transmitting large torque needs
Wheel.Because compared with metal gear, plastic gear all naturally has performance disadvantage in intensity, rigidity, precision.In addition there is injection
It is largely crystalline polymer to mold the material that the plastic gear formed uses, therefore the abrasion of plastic gear depends on resin
The degree of crystallization of material.In a mold, the resin cooling velocity of gear teeth portion is faster than gear body part, so as to gear teeth
Partial Resin crystallization degree is relatively low, causes to be easiest to the toothed portion rigidity of the gear of abrasion and wearability is relatively low instead.
Chinese patent CN105324594A discloses a kind of metal core for plastic gear and plastic gear combiner,
By periphery resin-bonded to ring portion, the plastic gear that shaft sleeve part, connecting portion, ring portion are formed by integrated continuous material is formed.So
And since the tooth of engagement is still metal, there is no solve the problems, such as gear wear.
In conclusion all there are certain limitations to determine for the various methods for improving gear lifes, tooth can not be fundamentally solved
The fatigue and wear problem of wheel.Gear-driven fatigue rupture and abrasion not only the consumption energy and cost material, but also due to tired
Labor is destroyed and is repaired when wearing and replacing component, consumed manpower and materials of stopping work and reduction labor productivity are just more serious
, therefore reliably gear is provided for convenience of efficient, it is current to reduce the fatigue of mechanical transmission component and fretting wear
The task of top priority.
