The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
One aspect according to the present utility model, the utility model proposes a kind of transmission mechanisms, according to the utility model
Specific embodiment, as depicted in figs. 1 and 2, which includes the driving mechanism 10 and driven member 20 being used cooperatively, institute
It states and is formed with quasi crystal coating on the surface of the driving contact position of at least one of driving mechanism 10 and the driven member 20
30。
As a result, at least one of driving mechanism and driven member in the transmission mechanism of the utility model above-described embodiment
Between the surface of driving contact position be respectively formed on quasi crystal coating, and then can to pass between driving mechanism and driven member
There is good lubricity and low coefficient of friction at dynamic contact position, can be effectively reduced the friction between drive mechanism, and due to
Two contact surfaces have quasi crystal coating transmission mechanism in the long-term use, and two contact surfaces are during gearing friction, drop
The low surface roughness of quasi crystal coating, to reach permanent lubrication, therefore transmission mechanism do not need addition lubricating oil or
The lubricants such as lubricating grease.Simultaneously as the quasi crystal coating having has good corrosion resistance and hardness, therefore the material of transmission mechanism
Common metal, such as iron, carbon steel, titanium and aluminum metal can be selected in material, it is particularly possible to stainless instead of 304 using common carbon steel
The more expensive metal of the prices such as steel, can significant save the cost.
Specific embodiment according to the present utility model includes aluminium, copper, iron, chromium and titanium in the quasi crystal coating.It is possible thereby to
Quasi crystal coating coefficient of friction is further decreased, its greasy property is improved, and then improves the service life and demoulding effect of transmission mechanism
Rate.
Specific embodiment according to the present utility model containing atomic percent is respectively 50-70% in the quasi crystal coating
Aluminium, the copper of 15-25%, the iron of 5-15% and summation be 5-15% chromium and titanium.It is possible thereby to further increase quasi-crystalline substance powder
The content and purity of middle quasi-crystalline substance.And the outermost electron of the quasi crystal coating with above-mentioned each element ingredient and proportion does not reconstruct
Phenomenon is always maintained at the electronic structure of pseudo energy gap to outer surface, and therefore, quasi-crystalline substance has surface energy minimum in metal system,
So that quasi-crystalline substance has preferable greasy property and lower coefficient of friction, and corrosion resistance is also relatively strong.Thus may be used
To further increase the hardness of quasi crystal coating, reduce coefficient of friction, and then the greasy property of transmission mechanism is significantly improved, avoids making

20%.In quasi crystal coating the partial size of quasicrystal particle be 20-80 μm, and if partial size it is excessive, will increase superficial roughness, reduce
Frictional behaviour；If partial size is too small, preparation cost is dramatically increased.Specifically, the partial size of above-mentioned quasicrystal particle can be 25 μm, 30
μm,40μm,50μm,55μm,60μm,70μm.It is possible thereby to further increase the driving contact face of driving mechanism and driven member
Flatness, reduce skin-friction coefficient.Therefore, inventors have found that quasi crystal coating has above-mentioned porosity and quasi crystal coating
When middle quasicrystal particle has above-mentioned partial size, greasy property is best.And when porosity is excessive or the partial size of particle is excessive,
The roughness on quasi crystal coating surface will be increased, so that lubricity declines.
The binding force of specific embodiment according to the present utility model, quasi crystal coating and driving mechanism and driven member is all larger than
50MPa, thus in operation process high-intensitive for a long time, quasi crystal coating still has good binding force, only can effectively protect
Hold the greasy property of transmission mechanism.
The hardness of specific embodiment according to the present utility model, quasi-crystalline substance layer is greater than 2.9GPa.It is possible thereby to further increase
The wearability of transmission mechanism, prolongs its service life, while can also reduce drive mechanism deformation occurs, to increase transmission essence
Degree.Improving hardness simultaneously can also prevent transmission mechanism from occurring the friction caused by physical deformations such as to scratch, scratch or collide
Phenomena such as power increases and the precision for further ensuring transmission.
In some embodiments of the utility model, between the driving contact face of the driving mechanism and the driven member
Coefficient of friction be 0.02-0.10.Preferably, the friction between the driving mechanism and the driving contact face of the driven member
Coefficient is 0.04-0.08.Thus lower coefficient of friction makes transmission mechanism have excellent lubricity, and then without using appointing
What lubricant, aging contaminated food products defect can occurs using lubricant to avoid the transmission mechanism in existing cooking equipment.
