| titleOfInvention | Sintering method of large-size silicon nitride bearing ball and preparation method of large-size silicon nitride bearing ball |
| abstract | The invention relates to a sintering method of a large-size silicon nitride bearing ball and a preparation method of the large-size silicon nitride bearing ball, belonging to the technical field of the large-size silicon nitride bearing ball. The sintering method of the large-size silicon nitride bearing ball comprises the following steps: and placing the silicon nitride spherical green body to be sintered on a supporting device, wherein the supporting device is provided with a supporting surface for supporting the lower spherical surface of the silicon nitride spherical green body, and sintering the silicon nitride spherical green body under the condition that the lower spherical surface is supported to obtain a silicon nitride bearing ball sintered blank. According to the method, the large-size silicon nitride bearing ball is sintered in a supporting sintering mode, the deformation of the large-size silicon nitride bearing ball can be relieved by sintering under the support, the obtained silicon nitride bearing ball sintering blank is high in size precision and good in surface quality, the processing precision is greatly improved, a foundation is established for the subsequent processing of the large-size high-precision bearing ball, and the method is suitable for the application fields of wind power bearings and the like requiring the large-size silicon nitride bearing ball. |
