Enter the first insertion groove, the second insertion groove is inserted in lower end, and is filled with the first Ka Gou and the second Ka Gou after heated remodeling shape.
Further, the first half raceway groove matched with ceramic balls and later half raceway groove are provided with the inside of the preceding outer ring and rear outer ring,
And do not contacted on the upside of first half raceway groove and later half raceway groove provided with indent with ceramic balls.
Further, the ceramic inner ring and ceramic balls use silicon nitride ceramics.
Further, the low-melting alloy ring uses terne metal.
Also include following supplementary features：Sealing ring is additionally provided between the ceramic inner ring and steel outer ring.
Above-mentioned bearing during fabrication, comprises the following steps：A, ceramic inner ring and rear outer ring are lain on installation mold,
Fill ceramic balls successively between the two.
B, load low-melting alloy ring in the second insertion groove of rear outer ring, be then pressed into preceding outer ring from top to bottom so that
Low-melting alloy ring is inserted in the first insertion groove of preceding outer ring, the front end face of outer ring after the rear end face fitting of preceding outer ring.
C, bearing is kept flat and compressed, under, preceding outer ring is heated, temperature is higher than to whole bearing upper for rear outer ring
The fusing point of low-melting alloy ring, more than 20 minutes time, nature is carried out to the ceramic inner ring after heating, steel outer ring, ceramic balls
It is cooled to room temperature.During, the heated thawing of low-melting alloy ring is filled with the first Ka Gou and the second Ka Gou, and one is formed after cooling
H-section ring fixes preceding outer ring and rear outer ring.
The utility model is consistent compared with the bearing of technology when in use, will not be repeated here.
The beneficial effects of the utility model are：Shape is remolded using low-melting alloy low temperature and ceramet is heat-resist
Feature, outer ring are divided into two and are easy to bead loading, and the splicing of outer ring is realized in overall heating again after bead loading, without opening bead installing hole.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to accompanying drawing 1 to 6, a kind of bearing, including a ceramic inner ring 1, steel outer ring 2 and full ball are laid in ceramic inner ring
Ceramic balls 3 between 1 and steel outer ring 2, the steel outer ring 2 is spliced by outer ring 5 after a preceding outer ring 4 and one, described
The preceding rear end of outer ring 4 is smooth and is arranged with the first insertion groove 6, and the both sides of the first insertion groove 6 are provided with the first card ditch 7；It is outer after described
Enclose 5 front ends smoothly and be arranged with the second insertion groove 8, the bottom both sides of the second insertion groove 8 are provided with the second card ditch 9, outer before described
Enclose the front end face of outer ring 5 after 4 rear end faces are bonded；Also include a low-melting alloy ring 10, the upper end of low-melting alloy ring 10 is inserted
Enter the first insertion groove 6, the second insertion groove 8 is inserted in lower end, and is filled with the first card ditch 7 and the second card ditch 9 after heated remodeling shape.
