Description

具有改进性能的滚动接触轴承
技术领域
本发明涉及具有改进性能的滚动接触轴承。
本发明还适用于例如使用在汽车的车轮轮毂中的滚动接触轴承。
背景技术
在机动车产业中，熟知的用于车轮轮毂的滚动接触轴承包括外构件和内构件，外构件和内构件之间配置有滚动元件，外构件和内构件进而设置有滚动元件用的相关滚道。
内构件和外构件的滚道表面任意地(/随机地)(randomly)形成有无数个(innumerable number)使表面微粗糙化(surface-microroughening)的微凹状凹陷(microconcave-like pit)。
为了减轻诸如摩擦或因润滑不足而导致的微动磨损(fretting)等的损坏，通过在滚道中设置微凹状凹陷以及通过设定诸如粗糙度Ra和作为粗糙度曲线的失真(/扭曲)(distortion)程度的偏斜度(skewness)Rsk等的相关参数，采用技术措施应对这些损坏。
发明内容
因此，本发明的目的是提供一种具有改进性能的滚动接触轴承，主要面对避免微动磨损和减轻摩擦的问题，并且优化相关性能。
为了实现上述目的，本发明提出具有方案1中限定的特征的具有改进性能的滚动接触轴承。
滚动接触轴承(优选用于汽车的车轮轮毂的滚动接触轴承)由内构件(或内圈)、外构件(或外圈)和布置在外构件与内构件之间的滚动元件构成。
外构件和内构件还设置有滚动元件用的相关滚道，并且内构件和外构件的滚道表面形成有无数个使表面微粗糙化的微凹状凹陷，其还由连续的(/一系列)(a successionof)顶(/平台)(plateau)和谷构成，其中如将在下文中公开的，顶(plateaus)减小滚动元件与圈之间的接触部内的局部压力，而深的谷用作脂储存部(/润滑剂储存部)。
具体实施方式
根据本发明的第一优选实施方式，在这些滚道表面中，为了增强滚动接触轴承中的微动磨损(摩擦磨蚀压痕(false brinelling))性能，粗糙度值Ra必须落在0.1微米至0.25微米之间的范围，并且组合地，偏斜度Rsk必须也为负且在范围-3.5<Rsk<-1.0内。
在0.1微米至0.25微米之间范围的粗糙度值Ra与在范围-3.5<Rsk<-1.0内的负偏斜度Rsk的组合产生(如下)滚道形貌(topography)，其中相对于峰，深的谷占有优势，并且更特别的是，通过设置具有较低表面的顶(plateaus)而消除了峰。较低表面的顶将减小接触(部)内的局部压力，而深的谷将用作脂储存部，进而增强了润滑作用。更低的局部压力和更好的润滑作用将降低微动磨损损坏的风险。
对于实现本发明的主要目标的程度，试验测试已经表明，如果粗糙度值Ra小于0.25微米，就能够达成该目标，以便避免危害滚道疲劳性能，并且由于更大的值对于微动磨损性能而言并非明显(/明确)有益。同时，当涉及摩擦时，偏斜度Rsk必须在范围-3.5<Rsk<-1.0内，理想的情形是使Rsk负得尽可能多，以减小中速时的摩擦，但是静摩擦和低速摩擦会略微增加更负的Rsk，并且当前的加工技术和标准工艺不允许实现高的负Rsk值，因此鉴于刚提及过的，大于或接近-0.35的偏斜度Rsk的值呈现出(/代表)(represents)良好的权衡点。
在边界润滑制度(/状态/方案)(regime)(a)中，对于中立(/中性)(neutral)而言，固-固粗糙(面)接触部(solid-to-solid asperity contact)的分数(/比例)(fraction)小于(对于)负偏斜度(的情况)。在后一种(/负偏斜度)的情况下，所有的顶都可能与配对物(counterpart)(出于简化起见，假设其是平滑的)接触。在负偏斜度的情况下较大分数的固-固粗糙接触部导致稍微更高的摩擦。
然而，在混合润滑(b)中，情况正好相反：当润滑剂膜变得足够厚以分开所述顶时(例如，伴随着速度加快)，在负偏斜度的情况下，固-固接触部的分数变小，对应于较低的摩擦。最后，在全膜(full-film)弹性流体动力(EHL(elastohydrodynamic))润滑(c)中，固-固粗糙接触(部)消失，摩擦变得对表面粗糙度参数不敏感。
根据本发明的第二优选实施方式，就所关心的滚动接触轴承的上述滚道表面而言，为了增强摩擦性能，粗糙度值Ra必须小于0.1微米，并且组合地，偏斜度Rsk也再次必须为负且在范围-3.5<Rsk<-1.0内。
负偏斜度Rsk与小于0.1微米的粗糙度值Ra的组合与具有微细(fine)粗糙度而没有任何高的峰但具有一系列带有谷的顶的滚道形貌对应。这种形貌的特征在于脂储存部和不存在高的粗糙性(/粗糙体)(asperities)，因此在混合润滑中提供了较少的固-固接触部，这意味着较低的摩擦。
以上公开的负偏斜度Rsk和粗糙度值Ra的组合将产生较低的微动磨损或较低的摩擦，具有使用相同脂的进一步优点，同时还将在中速时产生10％的负载球组摩擦减轻(loaded ballset friction reduction)。
应当理解，本发明不限于本文描述和示出的实施方式，这些实施方式应当视作是组件和其组装方法的示例；对于本领域的专家清楚的是，可以在不脱离如在权利要求及其等同物中限定的本发明的范围的情况下，在示例性实施方式所述的形式、尺寸、设计和功能细节以及元件的构造方面作出多种变型。
