Full-ceramic self-lubricating joint bearing forming method based on high-temperature superplasticity characteristic
The invention provides a full-ceramic self-lubricating knuckle bearing forming method based on the high-temperature superplasticity characteristic. The full-ceramic self-lubricating knuckle bearing forming method comprises the following steps that S1, a ceramic outer ring blank, a ceramic ball and a high-temperature compression performance test piece are prepared; s2, a bearing outer ring is prepared from the ceramic outer ring blank; performing a high-temperature compression test on the high-temperature compression performance test piece to obtain high-temperature performance parameters of the material; obtaining the optimal size of the inner ring according to finite element software in combination with the high-temperature performance parameters; processing the ceramic ball into an inner ring semi-finished product according to the optimal size; and S3, the semi-finished inner ring is sleeved with the finished outer ring, a carbon rod is inserted into the semi-finished inner ring, high-temperature upsetting is conducted, cooling is conducted, and the full-ceramic self-lubricating knuckle bearing is obtained. The method has the beneficial effects that the inner ring and the outer ring of the self-lubricating knuckle bearing in the method are both made of ceramic materials, overall forming and assembling of the full-ceramic self-lubricating knuckle bearing can be completed, and the application range and field of the bearing are widened to a certain extent.
本发明提供了基于高温超塑性特质的全陶瓷自润滑关节轴承成形方法，包括如下步骤：S1：制备陶瓷外圈坯料、陶瓷球、高温压缩性能测试试件；S2：陶瓷外圈坯料制备轴承外圈；高温压缩性能测试试件进行高温压缩试验，获得材料的高温性能参数；根据有限元软件并结合高温性能参数得出内圈最优尺寸；按照最优尺寸对陶瓷球加工成内圈半成品；S3：半成品内圈套入成品外圈中，并将半成品内圈内插入碳棒，进行高温墩粗，冷却得到全陶瓷自润滑关节轴承。本发明有益效果：本发明方法中的自润滑关节轴承的内外圈均采用陶瓷材料，能够完成全陶瓷自润滑关节轴承的整体成形装配，一定程度上拓宽了轴承的应用范围及领域。
