Abstract
The utility model provides a ceramic bearing which relates to the field of bearing manufacturing. The ceramic bearing comprises an outer ceramic ring (1), an inner ceramic ring (2) and ceramic balls (3), wherein the ceramic balls (3) are arranged in a gap between the outer ceramic ring (1) and the inner ceramic ring (2). Ceramic is corrosion-resisting, so that the ceramic bearing is suitable for working in a severe environment filled with corrosive mediums; the density and the weight of the ceramic balls is lower than those of steel, so that the centrifugal acting force of the ceramic balls to the outer ring in a rotation process can be reduced by 40%, and the service life of the outer ring is greatly prolonged; and the influence of expansion with heat and contraction with cold on the ceramic is small, so that the bearing can work in an environment with severe temperature difference change. The bearing is high in hardness and practicability, is wear-resisting.
Description
Technical field:
The utility model relates to a kind of bearing, is specifically related to a kind of ceramic bearing.
Background technique:
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Existing bearing adopts the steel bearing mostly, because the density ratio of steel is larger, so the bearing weight ratio is larger, the operating on centrifugal force to the outer ring during rotation is larger, has reduced the working life of bearing; The steel bearing is subjected to the impact of rising-heat contracting-cold larger simultaneously, thereby works under the steel bearing environment that difference variation is comparatively violent again.
The model utility content:
The purpose of this utility model provides a kind of ceramic bearing, and it can utilize ceramic distinctive physical property, overcomes the drawback of existing steel bearing, and corrosion resistance is good, can adapt to various abominable working environments.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises ceramic outer ring 1, ceramic inner ring 2 and ceramic balls 3, and ceramic balls 3 is arranged between the crack of ceramic outer ring 1 and ceramic inner ring 2.
The utility model is not because pottery is afraid of corrosion, so ceramic bearing suits to work being covered with under the rugged environment of Korrosionsmedium; Because the density ratio steel of ceramic balls is low, weight is light, and therefore the operating on centrifugal force to the outer ring can reduce by 40% when rotating, and greatly prolongs its working life; Again because the pottery impact of being expanded with heat and contract with cold is smaller, therefore in the gap one of bearing regularly, can allow bearing under the comparatively violent environment of difference variation, to work, hardness is high, and is wear-resistant, practical.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises ceramic outer ring 1, ceramic inner ring 2 and ceramic balls 3, and ceramic balls 3 is arranged between the crack of ceramic outer ring 1 and ceramic inner ring 2.
This embodiment is not because pottery is afraid of corrosion, so ceramic bearing suits to work being covered with under the rugged environment of Korrosionsmedium; Because the density ratio steel of ceramic balls is low, weight is light, and therefore the operating on centrifugal force to the outer ring can reduce by 40% when rotating, and greatly prolongs its working life; Again because the pottery impact of being expanded with heat and contract with cold is smaller, therefore in the gap one of bearing regularly, can allow bearing under the comparatively violent environment of difference variation, to work, hardness is high, and is wear-resistant, practical.
Claims (1)
