Abstract
The utility model discloses a kind of centripetal angular contact bearing, comprise outer ring and inner ring, the center of outer ring is provided with raceway in taper, and the cylindrical of inner ring is provided with tapered outer raceways, the center of inner ring is provided with mounting hole, and in the taper of outer ring, the tapered outer raceways of raceway and inner ring contacts rotation; In taper, raceway is consistent with the angle of taper of tapered outer raceways; In the taper of outer ring, the tapered outer raceways of raceway and inner ring is the assembling of Full connected form; In the taper of outer ring, the end diameter of raceway is not more than the end diameter of the tapered outer raceways of inner ring; In the taper of outer ring, the Outside diameter of raceway is not more than the Outside diameter of the tapered outer raceways of inner ring; The utility model good stability, there are self contering ability, long service life.
Description
Technical field
The utility model relates to a kind of centripetal angular contact bearing, particularly a kind of centripetal angular contact bearing of silicon wafer cutting equipment Special precision.
Background technique
In recent years, from international, Domestic market, photovoltaic market scale all keeps increasing fast always, domestic production capacity is sustainable growth also, government has also put into effect the photovoltaic support policy of the form such as tax reduction, financial subsidies recently, make the photovoltaic industry of China obtain tremendous development, also drive photovoltaic raw material especially the increasing considerably of metallic silicon production capacity.But the Special precision bearing on photovoltaic silicon chopper and slicer also exists centering problem that is unstable, that easily swing, and cause course of working unstable, low precision, cannot meet process requirements always.
Summary of the invention
The purpose of this utility model is to provide a kind of good stability, has the centripetal angular contact bearing of self contering ability, long service life.
The utility model is achieved by the following technical programs:
A kind of centripetal angular contact bearing, comprise outer ring and inner ring, the center of outer ring is provided with raceway in taper, and the cylindrical of inner ring is provided with tapered outer raceways, and the center of inner ring is provided with mounting hole, and in the taper of outer ring, the tapered outer raceways of raceway and inner ring contacts rotation.
The utility model realizes by the following technical programs further:
The centripetal angular contact bearing of aforesaid one, in taper, raceway is consistent with the angle of taper of tapered outer raceways.
The centripetal angular contact bearing of aforesaid one, in the taper of outer ring, the tapered outer raceways of raceway and inner ring is the assembling of Full connected form.
The centripetal angular contact bearing of aforesaid one, in the taper of outer ring, the end diameter of raceway is not more than the end diameter of the tapered outer raceways of inner ring.
The centripetal angular contact bearing of aforesaid one, in the taper of outer ring, the Outside diameter of raceway is not more than the Outside diameter of the tapered outer raceways of inner ring.
Inner ring of the present utility model and outer ring adopt the inside and outside raceway contact of taper, only have rotary motion, do not have oscillating motion, so have self-centering feature, successfully solve the centering shakiness that silicon section bearing exists, the problem easily swung.Because the inside and outside raceway of taper is Full connected design, effectively increases bearing capacity, add the working life of bearing.The large end end face of inner ring protrudes the large end end face of outer ring, and the small end sunken end face of inner ring is in the small end end face of outer ring, and such design is convenient for assembly with dismounting.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and be applied in photovoltaic silicon section field, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises outer ring 1 and inner ring 2, and the center of outer ring 1 is provided with raceway 11 in taper, and the cylindrical of inner ring 2 is provided with tapered outer raceways 21, the center of inner ring 2 is provided with mounting hole 22, and in the taper of outer ring 1, the tapered outer raceways 21 of raceway 11 and inner ring 2 contacts rotation; In taper, raceway 11 is consistent with the angle of taper of tapered outer raceways 21; In the taper of outer ring 1, the tapered outer raceways 21 of raceway 11 and inner ring 2 is the assembling of Full connected form; In the taper of outer ring 1, the end diameter of raceway 11 is not more than the end diameter of the tapered outer raceways 21 of inner ring 2; In the taper of outer ring 1, the Outside diameter of raceway 11 is not more than the Outside diameter of the tapered outer raceways 21 of inner ring 2; The mounting hole 22 of inner ring 2 is for external interface.
Due to the inside and outside raceway Full connected of taper, only have rotary motion, there is no oscillating motion, so the utility model has self-centering characteristic.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
