Abstract
The utility mode relates to a ceramic bearing. The ceramic bearing comprises an axle center and a axle sleeve; an axle hole is formed in the axle sleeve; the axle center is pivoted in the axle hole; a hollow hole is also formed on the axle sleeve, and is communicated with the axle hole; and the width of the hollow hole is larger than the diameter of the axle center. Owing to the hollow hole formed on the axle sleeve, the ceramic bearing reduces the contact area between the axle center and the axle sleeve, and also reduces the friction and the noise.
Description
Technical field
The utility model relates to a kind of ceramic bearing, relates in particular to the ceramic bearing of a kind of high rotating speed, low noise.
Background technique
The bearing structure of prior art sees also shown in the Figure of description 1, and it comprises an axle center 1a and an axle sleeve 2a, and this axle sleeve 2a is provided with axis hole 3a and articulates for axle center 1a.During the bearing rotation, axle center 1a and sleeve lining 4a can produce friction, and the space between axle center 1a and the axle sleeve 2a makes its vibrations and makes a noise, and the bearing high speed rotating can cause the fatigue of material, cause bigger frictional heat and vibrating noise, thereby working life is shorter.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of ceramic bearing, to overcome described defective of the prior art.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide the ceramic bearing of a kind of high rotating speed, low noise.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of ceramic bearing, comprise an axle center and an axle sleeve, and wherein, described axle sleeve is provided with an axis hole, and described axle center is articulated in the axis hole; Described axle sleeve further is provided with a hollow hole, and this hollow hole and axis hole connect, and its width is greater than the diameter in axle center.
Ceramic bearing of the present utility model also can be set to: described hollow hole is located on axle sleeve.
Compared with prior art, the utlity model has following beneficial effect: ceramic bearing of the present utility model is by offering a hollow hole on axle sleeve, thereby reduced the area of contact of axle center and axle sleeve, thereby reduced friction and noise.
Description of drawings
Fig. 1 is the stereogram of the bearing structure of prior art.
Fig. 2 is the stereogram of ceramic bearing of the present utility model.
Embodiment
See also shown in Figure 2ly, the utility model is a kind of ceramic bearing, comprises an axle center 1 and an axle sleeve 2.Wherein, described axle sleeve 2 is provided with an axis hole 3, and described axle center 1 is articulated in the axis hole 3.Described axle sleeve 2 further is provided with a hollow hole 5, and this hollow hole 5 connects with axis hole 3, and its width is greater than the diameter in axle center.Described hollow hole 5 is located on axle sleeve 2.
Ceramic bearing of the present utility model is by offering a hollow hole 5 on axle sleeve 2, thereby reduced the area of contact of axle center 1 and axle sleeve 2, thereby reduced friction and noise.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
1. a ceramic bearing comprises an axle center and an axle sleeve, and wherein, described axle sleeve is provided with an axis hole, and described axle center is articulated in the axis hole, it is characterized in that: described axle sleeve further is provided with a hollow hole, and this hollow hole and axis hole connect, and its width is greater than the diameter in axle center.
2. ceramic bearing as claimed in claim 1 is characterized in that: described hollow hole is located on axle sleeve.
