Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described in further detail.
As shown in Figure 1, fluted disc structure of the present utility model, comprises circular fluted disc body 1 and teeth 2, and fluted disc body 1 side is provided with installing hole 3, and for installing driving shaft, fluted disc body 1 opposite side is provided with fixing hole 4, for realizing being fixedly connected with of fluted disc and driving shaft.Described teeth 2 are positioned at the neighboring of fluted disc body 1, the shape of teeth 2 is halfpace type, the root (211 of teeth, 221) along with the neighboring of fluted disc body 1 forms level and smooth cambered surface, and the height of teeth root (211,221) is greater than the height of fluted disc body 1 neighboring.Increase teeth root (211,221) area, the lifting surface area of teeth can be increased, teeth root (211,221) along with the neighboring of fluted disc body 1 forms level and smooth cambered surface, make it not easy to crack under stressed effect, thus it is more reasonable that fluted disc structure of the present utility model is designed.
In order to make teeth 2 have larger contact area, have again stronger rigidity, hardness and smoothness, the upper end face of described teeth 2 is set to cambered surface, and the flexibility of cambered surface is less than the flexibility of circular fluted disc body 1 simultaneously.The side of described halfpace type teeth 2 and the angle of teeth 2 center line are 10-30 °.The distance of teeth root (211,221) distance teeth tip is the 25%-35% of fluted disc body 1 external diameter, and described teeth tip and fluted disc body 1 circumference length L in the same way equal the distance of described teeth root (211,221) to teeth tip.
In order to further enhancing the wearability of fluted disc body, extend the service life of fluted disc body, the utility model adopt there is the characteristic such as superior intensity, hardness, insulating properties, heat transfer, high temperature resistant, resistance to oxidation, corrosion-resistant, abrasion performance, elevated temperature strength structural ceramics as raw material to prepare fluted disc body 1 and teeth 2.Described structural ceramics comprises zirconia ceramics, silicon carbide ceramics, silicon nitride ceramics.
More specifically, fluted disc structure of the present utility model is two gear disk structure, as shown in Figure 2, can be split as the first fluted disc and the second fluted disc.
As shown in Figure 3 and Figure 4, the first fluted disc comprises the first fluted disc body 11 and the first teeth 21.First fluted disc body 11 is annular, is provided with guiding semicircle orifice 5 at the first fluted disc body 11 inner ring place, fixing for dislocation guiding when facilitating other assembling components.First teeth 21 are positioned at the first fluted disc body 11 neighboring, the shape of the first teeth 21 is halfpace type, the root of the first teeth 21 forms level and smooth cambered surface along with the neighboring of the first fluted disc body 11, and the height of the first teeth root 211 is greater than the height of the first fluted disc body 11 neighboring.In order to strengthen the intensity of fluted disc entirety, described first teeth 21 and the first fluted disc body 11 one-body molded.
As shown in Figure 5 and Figure 6, the second fluted disc comprises the second fluted disc body 12 and the second teeth 22.Described second fluted disc body 12 is annular, and the ring of the second fluted disc body 12 offers fixing hole 4, for realizing being fixedly connected with of the second fluted disc and driving shaft.Described fixing hole 4 is preferably screw hole.Second teeth 22 are also positioned at the neighboring of the second fluted disc body 12, the shape of the second teeth 22 is halfpace type, second teeth root 221 forms level and smooth cambered surface along with the neighboring of the second fluted disc body 12, and the height of the second teeth root 221 is greater than the height of the second fluted disc body 12 neighboring.Preferably, the external diameter of the second fluted disc body 12 equals the external diameter of described first fluted disc body 11, and the internal diameter of the second fluted disc body 12 is less than the internal diameter of the first fluted disc body 11.Described second teeth 22 are all identical with size with the first teeth 21 shape.In order to strengthen the intensity of fluted disc entirety, described second teeth 22 also with the second fluted disc body 12 is one-body molded.
First fluted disc and the second fluted disc are overlaped, make the guiding semicircle orifice 5 of the first fluted disc corresponding with fixing hole 4 position of the second fluted disc, the first teeth 21 are corresponding with the second teeth 22 position, as shown in Figure 1.The number of described fixing hole 4 and described guiding semicircle orifice 5 is preferably 3-5, is distributed on respectively on the first fluted disc body 11 and the second fluted disc body 12.The number of guiding fixing hole 4 and semicircle orifice 5 and distribute and mainly consider the intensity of the steadiness that fluted disc body is connected with driving shaft and fluted disc body.Very little, built on the sand, number is too many, causes the intensity of fluted disc body to reduce for the connection between fluted disc body and driving shaft for number.Thus the number of the utility model determination fixing hole 4 and guiding semicircle orifice 5 is preferably 3-5.
First driving shaft and fluted disc are installed, described driving shaft inserts from first fluted disc one end, then fixed on the driving shaft by the second fluted disc by the fixing hole 4 on the second fluted disc, the effect of holding tightly due to the second fluted disc makes the first fluted disc also securely be socketed on the driving shaft.During use, driving shaft High Rotation Speed, thus make the first teeth 21 and the second teeth 22 drive the abrasive media of its periphery and material to move with teeth 2, formation Crossed Circle rolls, strenuous exercise between abrasive media produces and shears, extrudes and rub, thus make the material stress deformation between medium and produce the field of force, reach the object improving grinding efficiency.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
