Description

Radially slotted bionic coupling gear
Technical field
The present invention relates to a kind of radially slotted bionic coupling gear.
Background technology
A lot of biological in order to adapt to living environment, it is evolved into impact, the mill that there is hard things such as resisting sandstone efficiently and cause Cut ability.Research finds, these organism surfaces are dispersed with geometric non-smooth form unit, and have certain regularity of distribution.Structure Become the local unit body of organism surface Non-smooth surface form, not only there is non-smooth surface feature, also there is special material composition, They are combined with body by the way of the biological coupling such as chimeric, compound, reach the effect of " rigidity strengthening " and " flexible absorbent ".
And in the field of high-end equipment, the vibration and the noise that how to reduce gear train assembly become mechanical transmission fields Important research contents.If some biological characteristic be applied on gear, the performance of gear train will be substantially improved, real The purpose of existing vibration and noise reducing.
Jilin University, the professor scholar of Southwest Jiaotong University have carried out certain research to bionical interfacing gears at present, main The wearability of gear to be directed to and the raising of anti-fatigue performance, the bionic coupling gear improved for nonlinear dynamic behavior performance Lack research.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of radially slotted bionic coupling gear, at common standard involute Slot on the coupling surface of gear, and filling flexible material in the trench, to reach the effect of " rigidity is strengthened, flexible absorbent ", from And reduce the vibration noise of machine driven system.
The radially slotted bionic coupling gear of the present invention, is fixed on the flank of tooth of gear including gear and embedding Flexible body;The flank of tooth of described gear is provided with and embeds fixing hole for flexible body or groove makes surface and the respective teeth of flexible body Face is equal.
Further, described flexible body is rubber, copper or babbit.
Further, described flexible body is symmetrical relative to facewidth center line.
Further, described flexible body is herringbone or the bar shaped radially extended along gear.
Further, described flexible body is the bar shaped radially extended along gear.
Further, described flexible body extends to tooth top from tooth root, and flexible body runs through the corresponding gear teeth along transverse tooth thickness direction.
Further, described flexible body is 1mm along the size that gear is axial.
The invention has the beneficial effects as follows: the radially slotted bionic coupling gear of the present invention, at common standard involute gear Coupling surface on slot or punch, and filling flexible material in groove or hole, to reach " rigidity is strengthened, flexible absorbent " Effect, thus reduce the vibration noise of machine driven system, improve nonlinear dynamic behavior performance.

Detailed description of the invention
Fig. 1 is the structural representation of the present invention;Fig. 2 is the left view of Fig. 1;Fig. 3 is radially slotted bionic coupling gear along x The acceleration of vibration amplitude spectrum in direction;Fig. 4 is standard involute gear acceleration of vibration amplitude spectrum in the x-direction;Fig. 5 is radially Fluting bionic coupling gear acceleration of vibration amplitude spectrum in the y-direction;Fig. 6 is that standard involute gear vibration in the y-direction adds Velocity amplitude is composed;As shown in the figure: the radially slotted bionic coupling gear of the present embodiment, it is fixed on including gear 2 and embedding The flexible body 1 of the flank of tooth of gear 2;The flank of tooth of described gear 2 is provided with the hole fixing for flexible body 1 embedding or groove makes The surface of flexible body 1 is equal with the corresponding flank of tooth, the flank of tooth fluting of gear 2 or punching, then embedding in groove or in hole Entering fixing flexible body 1, the flank of tooth after slotting or punching forms the complete flank of tooth, flexible body 1 surface and tooth with the combination of flexible body 1 surface Face seamlessly transits, and reaches the effect of " rigidity is strengthened, flexible absorbent ", thus reduces the vibration noise of machine driven system, improves Nonlinear dynamic behavior performance, flexible body 1 refers to that its hardness less than gear 2, can be the hardness metal material that is less than gear 2 Expect or have resilient nonmetallic materials;Flank of tooth fluting form is not unique, knits except fluting can also carry out other surfaces Structure, as the flank of tooth is set to convex-concave surface, all can realize the purpose of the present invention.
In the present embodiment, described flexible body 1 is rubber, copper or babbit, and elastic strong, ruggedness is good.
In the present embodiment, described flexible body 1 is symmetrical relative to facewidth center line, flank of tooth stress when making to engage between gear, protects The stability of card gear engagement, reduces noise.
In the present embodiment, described flexible body 1 is herringbone or the bar shaped radially extended along gear 2.
In the present embodiment, described flexible body 1 is the bar shaped radially extended along gear 2;Described flexible body 1 prolongs from tooth root Extending tooth top, and flexible body 1 runs through the corresponding gear teeth along transverse tooth thickness direction, described flexible body 1 along the size that gear 2 is axial is 1mm, can make flexible body 1 act on all the time during pinion rotation between two flank of tooth being meshed.
Verifying that radially slotted bionic coupling gear mesh reduces vibration by contrast experiment the most useful, one group is radially slotted Bionic coupling gear engages, and another group engages for standard involute gear, uses acceleration transducer to measure, experiment is measured To data import in Matlab and carry out process and obtain acceleration comparison diagram, do not consider axial jump, along the acceleration in x, y direction Comparison diagram such as Fig. 3-6, it is clear that radially slotted bionic coupling gear acceleration is obviously reduced, this illustrates radially slotted bionic coupling It is the most favourable that gear mesh reduces vibration.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, although with reference to relatively The present invention has been described in detail by good embodiment, it will be understood by those within the art that, can be to the skill of the present invention Art scheme is modified or equivalent, and without deviating from objective and the scope of technical solution of the present invention, it all should be contained at this In the middle of the right of invention.Such as flank of tooth fluting form is not unique, even can also carry out other tables except fluting Plane texture.
