Embodiment Construction
[0020] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a steel back layer 1, a base layer 2 and a slightly soluble layer 3 from outside to inside, wherein the base layer 2 is an aluminum material, and the slightly soluble layer 3 is an environmentally friendly iron-silicon material; the composition of the iron-silicon environmental protection material is : Fe 30-38%, Si 60-68%, Al2-4%; the thickness of the base layer 2 is 0.05-0.15mm, and the thickness of the slightly soluble layer 3 is 0.05-0.90mm; the steel back layer 1, base layer 2 and the slightly soluble layer 3 are adhered together by high temperature sintering.
[0021] When the inner surface of the bearing pad matching the shaft diameter contacts the grease, the iron-silicon environmental protection material can form a slightly soluble layer, absorb the lubricating oil on the sliding surface of the bearing pad, and reliably form an oil film, so that the friction...
