Description
本发明涉及轴承组件。
金刚石轴承组件是众所周知的,而且其应用领域非常广泛。金刚石轴承组件的应用领域之一是在钻井行业中用于井下电动机。
在金刚石轴承组件中,组件的相对设置的轴承表面是由金刚石材料制造的一对元件。所谓金刚石材料是多晶体金刚石,或简称PCD。工艺上作为一种金刚石坯块的金刚石材料是公知的,采用这种材料是因为其耐磨损寿命很长,而且其能够承受相当大的载荷。在现有技术中已知,用于金刚石轴承组件的多晶体金刚石是商标名为Syndite,Syndrill或Stratapax的产品。在这种多晶体金刚石材料中包含大量的第八类金属(元素周期表),例如钴、铁或镍。在这一方面可以参照美国专利US-4620601,第12栏,第30~37行,以及美国专利US-4560014第9栏,第29~44行。
美国专利US-5092687中描述的金刚石轴承组件具有相对设置的金刚石轴承表面。通过粘接碳化钨设置金刚石轴承表面,在碳化钨材料中结合着合成金刚石,见该文件第3栏,第49~51行。在粘接的碳化钨中具有第八类金属、例如钴、镍或铁、用其作为碳化钨的粘结剂。
已经发现,在金刚石轴承组件中采用包含第八类金属的金刚石材料,如上述相关文献所述,轴承接触表面的摩擦工况在高接触压力条件下,倾向于产生相当大程度的不可预见性。在某些情况下,轴承组件在没有足够的预警情况下迅速擦伤。显然这种现象是由于含有丰富的第八类金属元素构成的摩擦膜引起的。这种摩擦膜,在轴承组件的使用过程中,在金刚石轴承表面形成。
按照本发明,轴承组件包括相对设置的金刚石轴承表面,至少有一个轴承表面的材料不属于任何第八类金属。
至少相对设置的金刚石轴承表面之一绝不属于任何第八类金属,最好两个表面的材料都不属于任何第八类金属。术语“不属于任何第八类金属”意味着基本上在轴承表面无第八类金属,尽管可能存在微量的第八类金属,其并不产生有害效果。在第八类金属中包括钴,铁和镍。
图1和图2是表示本发明中两个轴承组件的相对设置的金刚石轴承表面的局部示意图。
本发明提供一种轴承组件,其包括相对设置的金刚石轴承表面元件。轴承组件可以是现有技术中已知的任何一种。本发明具有特殊用途,如在钻井行业中用于井下电动机的金刚石推力轴承组件。例如,在美国专利US-4560014和欧洲专利申请EP-933085912中描述的这种轴承组件的实例。已经发现,至少在相对设置的一个金刚石轴承表面元件中缺少,或基本上没有第八类金属时,可以获得很低的摩擦系数,其值不大于0.1,而且其承载能力相当于接触压力68MPa或更高。
最好两个金刚石轴承表面元件都没有第八类金属。
没有第八类金属的金刚石轴承表面可以由任何一种金刚石基材的表面提供。这种金刚石基材之一,以及优选的金刚石基材是其实质上由金刚石与金刚石相粘结,而且基本上由硅构成第二相,所述硅以硅和/或碳化硅的形式存在。金刚石含量在体积上通常占80~90%,而金刚石与金刚石的粘结剂通常形成起结合作用的骨架。含硅的第二相的体积含量通常为10~20%。美国专利US-4151686和US-4793828中描述了这种金刚石体的实施例。还有,这种金刚石体的一个例子是以商标名Synclax销售的产品。
另一种能够提供缺少或基本没有第八类金属的表面元件的金刚石体包括体积含量为70~95%的自粘结金刚石体内遍布着空的微孔。在金刚石体中可以包括微量的金属相,这种金属相基本上均匀普遍地渗透在金刚石体内。这种金刚石体称为可滤取的金刚石坯,在美国专利US-4224380中叙述了有关实例。
没有第八类金属的金刚石表面元件也可以由金刚石薄膜表面提供,这种金刚石薄膜表面由化学蒸汽沉积(简称CVD)构成。CVD金刚石薄膜可以在碳化硅、碳化钨和同类材料上形成。在现有技术中制成CVD金刚石薄膜是众所周知的,即分解气化的碳化合物,产生碳原子、离子或官能团,使它们沉积在材料表面,形成金刚石薄膜。
无第八类金属的金刚石表面元件也可以由金刚石坯的表面元件提供,这种金刚石坯在金刚石合成状态下产生,其体积含量至少为70%,最好为80~90%。金刚石,实质上金刚石与金刚石的粘结剂和第二相由碳化的碱土金属,最好是碳化钙构成。
下面参照附图描述本发明的两个实施例。第一实施例参照图1,其表示的轴承组件包括相对设置的轴承表面元件10和12。表面元件10和12分别由金刚石坯14和16的一个表面形成。这两个金刚石坯都可以没有任何第八类金属。另外,至少这些金刚石坯中的一个绝没有任何第八类金属,以致至少轴承表面元件10、12之一没有这种金属。
参照图2,由表面20和22限定轴承组件中相对设置的轴承表面元件。轴承表面20在金刚石坯24的一个表面上形成。轴承表面22形成金刚石体28中金刚石端部区域26的一个表面。金刚石端部区域26可以由商标为SyncLax,经过滤取的金刚石坯,或CVD金刚石层构成。区域26与材料30相粘结,材料30可以是包含金刚石的基体28,例如金刚石坯,或者这种基材右可以由不同的材料,如粘结的碳化物制成。
在另一个未图示的实施例中,金刚石坯24可以由相同于金刚石体28,含有金刚石的合成金刚石体代替。
使用各种金刚石轴承表面元件进行一系列试验。利用针盘式摩擦计可以产生不可预见的滑动运动。在这个机构中,滑动付(针)的一个元件固定在悬臂的载荷支撑臂上的样品夹具上。在常速或变速电动机的驱动下,所述的针可以在水平盘上滑动或回转。作用在针上的载荷可以变化,而且这个载荷由作用在载荷支撑臂上的固定垂物装置施加。
使用的产品是Syndriu产品,金刚石坯或PCD产品包含大约10%(重量比)的钴,这些钴均匀地分散或分布在整个被粘结的金刚石坯中。而在Syndax产品中,金刚石体中实质上包括金刚石与金刚石的粘结剂和基本上由硅构成的第二相。这种硅以硅和/或碳化硅的形式存在。在进行的各种试验中,用Syndriu产品制造针和盘,用Syndxx产品制造针和盘,以及用Syndriu产品制造针和盘之一,而用Syndax产品制造另一元件。
当采用Syndax产品制造针和盘时,在干的无润滑滑动试验中,可以获得最低摩擦系数。已经发现,采用这种方案得到的低摩擦系数不大于0.1,而且具有至少4300N的高承载能力,其相当于至少可以承受68MPa的接触压力。这一结果与针和盘都由Syn-drill产品制造时的方案形成显著对比,后者具有较高的摩擦系数0.13~0.26,而承载能力较低,大约为2800N,相当于接触压力44MPa。在后一种情况中,发现在滑动表面形成了含钴量丰富的摩擦膜。可以相信,这是导致高摩擦系数的症结。去除这种摩擦膜,例如用Hcl,可以暂时减小摩擦系数,直到摩擦膜被改变为止。
在另一些试验中,用Syndax产品制造针,而用Syndriu产品制造盘,或者与此相反。而且在干的,无润滑滑动状态下使用。已经发现,这种结合形式具有的摩擦系数低于Syndriu产品与Syn-driu产品相结合时具有的摩擦系数。另外,虽然在轴承表面可以观察到摩擦膜,这种摩擦膜主要包含了硅和仅仅少量钴。因此,事实上受压的硅形成有害的具有富钴的摩擦膜,其导致摩擦系数降低。
用水作为润滑剂进行一系列同样的试验。一对Syndriu/Syn-driu产品的承载能力很小,仅为2800N,尽管其可以获得很小的摩擦系数,为0.1。然而,一对Syndax/Ayndax产品在同样工况条件下,如在无润滑滑动试验中,其摩擦系数不大于0.1,而且承载能力高于4300N,其相当于高于接触压68MPa。
