Summary: | A functionally graded material motor bearing capable of reducing electric corrosion comprises a bearing outer ring, a bearing inner ring and a plurality of balls, and the bearing outer ring sequentially comprises a ceramic ring layer, a functionally graded mixed material ring layer and a bearing steel ring layer from outside to inside in the radial direction. The bearing inner ring sequentially comprises a bearing steel ring layer, a functional gradient mixed material ring layer and a ceramic ring layer from outside to inside in the radial direction; the functional gradient mixed material is formed by mixing a ceramic material and a bearing steel material, and the mixing volume ratio of the two materials meets a gradient distribution function in the radial direction. The bearing steel ring layer can reduce the grinding cost and ensure the bearing capacity of the raceway to the balls; the ceramic ring layer has the functions of heat insulation and electricity retardation, so that the insulativity of the bearin |
