Abstract
The utility model provides a ceramic bearing ring has the bearing ring, bearing ring surface evenly distributed has a plurality of trapezoidal dogteeth that are down, and the bearing ring all adopts ceramic material integrated into one piece with the dogtooth, has poured into the daub between each dogtooth, and the dogtooth upper surface is the arc, and each dogtooth combines the surface that forms with the daub to be circular, and the thickness of dogtooth is not more than the thickness of bearing ring. The utility model discloses an improvement ceramic bearing ring's structure makes it have clay and ceramic compound rolling surface, can bear effective impact and roll extrusion, and difficult production fracture improves life.
Description
The technical field is as follows:
the utility model relates to a ceramic bearing technical field refers in particular to a ceramic bearing ring.
Background art:
the performance of four bearing materials, namely common bearing steel, stainless steel, silicon nitride and zirconia is in contrast, and a ceramic bearing is used as an important mechanical basic part and is increasingly widely applied in various fields of the national civilization due to the superior performances of wear resistance, high temperature resistance, high strength and the like which cannot be compared with a metal bearing. At present, although the existing ceramic bearing is superior to a metal bearing by virtue of excellent performance, the ceramic has the defects of poor rolling resistance due to strong hardness and low toughness, and particularly, the existing ceramic bearing cannot unload force and is easy to generate cracks in a high-impact rolling working state.
The invention content is as follows:
an object of the utility model is to prior art current situation, provide a ceramic bearing ring that has shock-absorbing capacity, can resist impact.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model relates to a ceramic bearing ring has the bearing ring, bearing ring surface evenly distributed has a plurality of trapezoidal dogteeth that are down, and the bearing ring all adopts ceramic material integrated into one piece sintering shaping with the dogtooth, has poured into the clay between each dogtooth.
In the scheme, the upper surfaces of the convex teeth are arc-shaped, and the outer surface formed by combining each convex tooth with the daub is circular.
Further, the thickness of the teeth is not greater than the thickness of the bearing ring.
The utility model has the advantages that: the structure of improvement ceramic bearing ring, bearing ring surface form a plurality of trapezoidal dogteeth of falling, can fill the clay between each dogtooth, and with the compound rolling surface that forms of clay, have the effect of buffering power of unloading, can bear effective impact and roll extrusion, difficult fracture that produces improves life.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
please refer to fig. 1, which is a schematic structural diagram of a preferred embodiment of the present invention, the present invention relates to a ceramic bearing ring, which comprises a bearing ring 1, wherein a plurality of inverted trapezoidal teeth 2 are uniformly distributed on the outer surface of the bearing ring 1, that is, the teeth 2 have a large end at the upper surface and a small end at the inner part connected to the bearing ring 1, the bearing ring 1 and the teeth 2 are all made of a ceramic material and integrally sintered, cement 3 is filled between the teeth 2, and then the ceramic bearing ring is sintered at 400 ℃.
The upper surfaces of the convex teeth 2 are arc-shaped, the outer surface formed by combining each convex tooth 2 with the daub 3 is circular, so that the composite bearing ring can be ensured to form a complete circular outer contour, and the composite bearing ring is suitable for rolling and sliding work.
The thickness of the convex teeth 2 is not larger than that of the bearing ring 1, so that the force transmission can be uniformly dispersed on the convex teeth 2 and the bearing ring 1, and the bearing ring has rolling resistance and toughness under the condition of impact resistance, and avoids the fracture caused by rolling.
Of course, the above illustration is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so all equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
