Problems solved by technology

[0002] The bearing bushes used in existing automobile engines are generally copper-lead alloys or aluminum alloys. Although their products have good load-carrying capacity, most alloy materials contain environmental pollutants to varying degrees, and when the engine is started, the lack of lubricating oil will cause Burning tiles, holding shafts, and accidents often need to be compensated by increasing surface plating, but this will lead to high costs and environmental pollution

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...

Abstract

The invention relates to a bearing, in particular to a sparingly soluble bearing of an engine. The sparingly soluble bearing is characterized by comprising a steel back layer, a substrate layer and a sparingly soluble layer which are arranged from outside to inside, wherein the substrate layer is made of aluminum material; and the sparingly soluble layer is made of silicon-iron environment-friendly material. The invention saves energy in the manufacture process, has low cost and can satisfy the technical requirements of the engine, such as high voltage increase, great torque and low emission.

Description

(1) Technical field [0001] The invention relates to a bearing bush, in particular to a slightly soluble bearing bush for an engine. (2) Background technology [0002] The bearing pads used in existing automobile engines are generally copper-lead alloys or aluminum alloys. Although their products have good bearing capacity, most of the alloy materials contain environmental pollutants to varying degrees, and when the engine is started, the lack of lubricating oil will cause Burning tiles, holding shafts, and accidents often need to be compensated by increasing surface electroplating, but this will lead to high costs and environmental pollution. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides an environmentally friendly, energy-saving, and long service life slightly soluble bearing bush of the engine. [0004] The present invention is achieved through the following technical solutions: [0005] A sligh...
