Description

铜粉中包裹有石墨的双金属轴承 Graphite inclusions in copper bimetal bearing

技术领域 FIELD

[0001] 本发明涉及一种复合轴承,尤其涉及一种铜粉中包裹有石墨的双金属轴承。 [0001] The present invention relates to a composite bearing, particularly to a double wrapped with copper in metal-graphite bearing. 背景技术 Background technique

[0002] 传统的滑动轴承大多是全部用铜合金浇注铸成轴套,再经切削加工而成,这样的结构制造成本高,特别是随着有色金属价格的上涨,这种整体的铜合金轴承被称作双金属轴承所替代。 [0002] Most of conventional sliding bearings are all cast copper alloy casting sleeve, and then processed by cutting, which has high manufacturing cost of such a structure, particularly with the rise of the price of non-ferrous metals, copper alloy of this whole bearing It is called bimetal bearings replaced. 目前的双金属轴承的制造方法是以钢板为基体,在钢板的表面均勻地铺上铜合金粉末,并使其具有一定的铺撒厚度;然后进行烧结、轧制,铜-钢双金属轴承材料,其中专利申请号为200510110718. 7的含磷量大于0. 1 %的磷青铜-钢双金属轴承材料制造工艺就是以这样的工艺来生产铜-钢双金属轴承材料的。 The current method for producing a bimetallic bearing Steel substrate body, the surface of the steel sheet uniformly covered with the copper alloy powder, and it has a certain Spreading the thickness; and then sintered, rolled, copper - - steel bearing material, wherein the phosphorous Patent application No. 200510110718.7 greater than 0.1% of phosphor bronze - - steel bearing material in the manufacturing process is such a process to produce copper - - steel bearing material. 但由于铜合金粉末的摩擦性能差,在许多场合需要经常加润滑剂,这对使用的工况受到一定的限制。 However, due to poor frictional properties of the copper alloy powders, on many occasions, often require additional lubricant, which subject to certain restrictions on the use conditions. 之后又有在铜合金或用优质碳素结构钢或轴承钢为基体;基体的内壁结合有铸造铜合金耐磨材料层,在轴承的摩擦面上制有通孔或盲孔,在通孔或盲孔中镶嵌有高纯度石墨的固体润滑柱,使镶嵌的固体润滑柱更有自润滑、耐磨的优良特点,市场上称作JDB的自润滑轴承。 After the copper alloy or another quality carbon steel or bearing steel as substrate; an inner wall of the base body incorporates a cast copper alloy layer of wear-resistant materials, a through hole or a blind hole made in the bearing surface of the friction, the through-hole or blind hole has a high purity graphite embedded solid lubricating column by column so that a solid lubricant embedded more self-lubricating, good wear characteristics, JDB called self-lubricating bearings on the market. 如专利200710066851. 6 钢基铜合金镶嵌固体润滑轴承及其制法。 Patent 200710066851.6 copper-based alloy steel bearing inlaid solid lubricating method thereof. 虽然经镶嵌有石墨的固体润滑柱后使滑动轴承的自润滑和耐磨性比原来的双金属轴承有了明显提高,但在基体上钻孔生产效率低,劳动强度大、工艺复杂,而且在孔的位置不能承载,使得轴承的有效承载面积减少五分之一左右, 而且滑动轴承的强度也大大降低,且制造成本又高。 Although the solid lubricating graphite column enable self-lubricating sliding bearings and wear resistance than the original double-metal bearing has been significantly improved, but the low productivity in drilling a substrate, labor-intensive, complex process was embedded, and in the position of the holes can not carry such a bearing to reduce the effective bearing area about one-fifth, and the sliding bearing strength is greatly reduced, and the manufacturing costs are high.

发明内容 SUMMARY
