Abstract

嵌有固体润滑剂的钢基铜合金轴套，至少包括钢套外层，其内表面上熔结有铜合金层。铜合金层上制有油槽并且嵌有固体润滑剂。本实用新型兼有抗冲击力大、导热性好和低摩擦的优点，特别适合已有技术无法应用的中低载、中速运动且无法经常加油润滑的场合。

Description

嵌有固体润滑剂的钢基铜合金轴套
所属技术领域
本实用新型在国际专利分类表中，属于轴、轴承小类，即F16C小类，特别涉及钢铜二层复合轴承。
背景技术
目前，在国内模具行业中，由于结构更趋紧凑和工作环境无油污的要求，因此作为导向的轴套不能用连续注油润滑的方法。而断续润滑虽然满足了上述要求，但带来了轴套温升快，耐磨性能下降的弊病，常常出现业界所说的“咬轴”现象。
实用新型内容
本实用新型的目的是提供一种嵌有固体润滑剂的钢基铜合金轴套，它能适应中低载、中速并且无法经常加油的直线往复或旋转运动的机械要求。
公开新的技术方案如下：
嵌有固体润滑剂的钢基铜合金轴套，至少包括钢基外层，其特征是钢基外层的内表面上熔结有铜合金层并且制有油槽，油槽内嵌有固体润滑剂。
按上述方案制成的样品，其钢铜层间结合力大，实测大于80MPa，远大于钢基烧结或镀铜结合力的16MPa。这种轴套既有钢层抗冲击力大的优点，又具备铜层导热性、耐磨性好的长处，特别是制有油槽并且嵌有固体润滑剂的结构，使轴承在工作时，即使在无油状态下，由于固体润滑剂通过摩擦热形成一层转移膜，从而大大降低了摩擦系数，不致造成“咬轴”现象。
附图说明
图1为本实用新型一个实施例的剖面示意图。图2为图1的左视图。图3为图1的局部剖视放大示意图。
具体实施方式
嵌有固体润滑剂的钢基铜合金轴套，至少包括钢基外层1，其内表面上熔结有铜合金层2。铜合金层2的表面制有油槽3且嵌有固体润滑剂4，所述固体润滑剂选择石墨或/和二硫化钼或/和聚四氟乙烯及其混合物。所述铜合金层2为锡青铜，厚度以1-2毫米为佳。所述油槽3可为封闭环形、螺旋线形或“8”字形。钢基外层1以优质碳素结构钢或轴承钢为宜。为安装方便，钢基外层1可带有法兰。
