Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] refer to Figure 1 ~ Figure 3 , a ceramic bearing, including an outer ring 1 and an inner ring 2, the inner ring 2 is nested in the outer ring 1, the inner hole of the outer ring 1 is an inverse spherical surface, and the outer surface of the inner ring 2 is a conical surface , the inclination angle of the tapered surface is 5-10°, and the centerline of the inner hole of the outer ring 1 is in contact with the neutral line of the outer side of the inner ring 2 .

[0015] Further, the inclination angle of the tapered surface is 6-8°.

[0016] In this embodiment, the shape of the inner hole of the outer ring (anti-spherical surface) and the shape of the outer diameter of the inner ring (conical surface) are changed to reduce friction, facilitate processing and withstand axial force.

[0017] In this embodiment, nano ceramic materials are preferably used.

Abstract

A ceramic bearing comprises an outer ring and an inner ring. The inner ring is nested in the outer ring; an inner hole of the outer ring is an adverse spherical surface; an outer side of the inner ring is a conical surface with a dip angle of 5-10 DEG; and a central line of the inner hole of the outer ring contacts with and the neutral line of the outer side of the inner ring. The invention provides a ceramic bearing with good friction reducing property, good heat resistance and reduced cost.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a ceramic bearing. Background technique [0002] At present, bearings include powder metallurgy sliding bearings and bearing steel rolling bearings: sliding bearings have the advantages of simple structure and low price, but their performance is also poor; rolling bearings have the characteristics of excellent performance but complex structure. [0003] In recent years, in order to improve the friction resistance of rolling bearings, balls or rings made of ceramic materials have been used. Although the performance has been improved, the economy has declined due to the substantial increase in manufacturing costs. Contents of the invention [0004] In order to overcome the disadvantages of poor friction reduction, poor heat resistance and high cost of existing ceramic bearings, the present invention provides a ceramic bearing with good friction reduction performance, good heat resistance...
