Problems solved by technology

[0002] Ceramic bearings are made of ZrO 2 ·Y 2 o 3 or Al 2 o 3 It is sintered from other powders and has the advantages of light weight, high strength, wear resistance, heat resistance, etc. It has been widely used in fans, hard disks and other electronic products. The existing ceramic bearings 1 such as figure 1 As shown, it has a shaft 2 and a bushing 3, and the bushing 3 has a shaft hole 4 in the center for the shaft 2 to pass through, because the shaft 2 is attached to the inside of the shaft hole 4 Therefore, when the shaft center 2 rotates relative to the bushing 3, it will still generate noise and heat, which not only causes discomfort to the user, but also tends to shorten the service life of the bearing

Embodiment Construction

[0011] see figure 2 , image 3 , The ceramic bearing 10 provided by the first preferred embodiment of the present invention includes a shaft 20 and a bushing 30 .

[0012] The shaft 20 is in the shape of a cylindrical rod, and the bushing 30 is provided with a shaft hole 32 for the shaft 20 to pass through. The shaft hole 32 has a large diameter portion 34 and two small diameter portions 36. The two small diameter portions 36 They are respectively located at the top and bottom ends of the large-diameter portion 34 , the small-diameter portions 36 are attached to the outer edge of the shaft 20 , and there is a predetermined gap between the large-diameter portion 34 and the shaft 20 .

[0013] Because the shaft 20 is only in contact with the small diameter portion 36 of the shaft hole 32 of the bushing 30 with its two ends; so when the shaft 20 rotates relative to the bushing 30, the noise it sends is small, and because the shaft The friction between the core 20 and the bushi...

Abstract

The invention relates to a ceramic bearing, which includes an axis and a bush. A axle hole disposed on the bush lets the axis pass through. The axle hole includes one big diameter part and two small diameter parts. The two small diameter parts are located at the two ends of the big diameter part separately.

Description

technical field [0001] The present invention relates to bearings, in particular to a ceramic bearing, which is quiet in use, good in heat dissipation, light in structure and long in life. Background technique [0002] Ceramic bearings are made of ZrO 2 ·Y 2 o 3 or Al 2 o 3 It is sintered from other powders and has the advantages of light weight, high strength, wear resistance, heat resistance, etc. It has been widely used in fans, hard disks and other electronic products. The existing ceramic bearings 1 such as figure 1 As shown, it has a shaft 2 and a bushing 3, and the bushing 3 has a shaft hole 4 in the center for the shaft 2 to pass through, because the shaft 2 is attached to the inside of the shaft hole 4 Therefore, when the shaft center 2 rotates relative to the bushing 3, noise and heat will still be emitted, which not only causes discomfort to the user, but also tends to shorten the service life of the bearing. Contents of the invention [0003] The main purp...
