In addition to structural design, Xuzhou NSK bearings have four main aspects: impact, material, manufacturing, use and lubrication technology.
(1)材料影響:在軸承材料技術上,主要通過材料選擇、材料保證和熱處理,保證軸承壽命的提高。滾動軸承一般采用高碳鉻軸承鋼,其化學成分基本不變。但是,不同冶煉方法中物料的純度不同,對使用壽命有很大影響。因此,材料對徐州NSK軸承疲勞壽命的影響非常重要。
(1) Material influence: In the bearing material technology, mainly through material selection, material assurance and heat treatment, to ensure the increase of bearing life. High carbon chromium bearing steel is generally used in rolling bearings, and its chemical composition is basically unchanged. However, the purity of materials in different smelting methods is different, which has a great impact on the service life. Therefore, the influence of materials on the fatigue life of Xuzhou NSK bearings is very important.
(2)表面粗糙度的影響:疲勞裂紋通常起源于表面,因此表面對零件的壽命有很大的影響。表面越光滑,疲勞裂紋萌生時間越長。滾動軸承的滾動體和軸承套圈的表面處理技術可以改變滾動體表面材料的硬度、殘余應力分布和整體強度,從而提高軸承的壽命。
(2) The influence of surface roughness: Fatigue cracks usually originate from the surface, so the surface has a great influence on the life of parts. The smoother the surface is, the longer the fatigue crack initiation time is. The surface treatment technology of rolling element and bearing ring of rolling bearing can change the hardness, residual stress distribution and overall strength of the surface material of rolling element, thereby improving the life of bearing.
(3)溫度的影響:無論是基于表面應力疲勞模型還是從表面缺點開始,都不考慮接觸區加熱對軸承疲勞壽命的影響。事實上,軸承的連續運行須伴隨一定的溫升。徐州NSK軸承溫升范圍應與接觸副之間的潤滑膜厚度、接觸件的表面特性、負載和運行速度有關。
(3) The influence of temperature: whether based on the surface stress fatigue model or from the surface shortcomings, the influence of contact zone heating on Bearing fatigue life is not considered. In fact, the continuous operation of bearings must be accompanied by a certain temperature rise. The temperature rise range of Xuzhou NSK bearings should be related to the thickness of lubrication film between contact pairs, the surface characteristics of contact parts, load and running speed.
(4)潤滑技術的影響:在軸承潤滑技術中,主要通過選擇潤滑油和潤滑方式來提高軸承的使用壽命。潤滑技術已成為提高軸承壽命的關鍵因素之一。特別是對于密封軸承,潤滑脂壽命已成為軸承使用壽命的另一個“代詞”,即潤滑脂壽命是軸承的使用壽命。
(4) The influence of lubrication technology: In the bearing lubrication technology, the service life of bearings is improved mainly by choosing lubricating oil and lubricating methods. Lubrication technology has become one of the key factors to improve bearing life. Especially for sealed bearings, grease life has become another "pronoun" of the service life of bearings, that is, grease life is the service life of bearings.
(5)運行速度的影響:徐州NSK軸承疲勞壽命與瞬時接觸時間有關。瞬時接觸時間是指在較大載荷下接觸滾圈與滾體之間滾道橢圓寬度所需的時間。隨著轉速和瞬時接觸時間的增加,軸承的疲勞壽命降低。軸承運轉越慢,通過旋轉測量的軸承使用壽命越長。
(5) The influence of running speed: The fatigue life of Xuzhou NSK bearing is related to the instantaneous contact time. Instantaneous contact time refers to the time required to contact the elliptical width of the raceway between the rolling ring and the rolling body under larger loads. With the increase of rotational speed and instantaneous contact time, the fatigue life of bearings decreases. The slower the bearing runs, the longer the service life of the bearing measured by rotation.
(6)載荷效應:滾子參數和曲率系數對深溝球軸承的疲勞壽命影響很大。結果表明,載荷對深溝球軸承的疲勞壽命影響很大。滾動軸承的疲勞壽命在很大程度上取決于大滾動載荷。因此,隨著載荷的增加,大滾動載荷顯著增加,疲勞壽命降低。
(6) Load effect: Roller parameters and curvature coefficient have great influence on the fatigue life of deep groove ball bearings. The results show that the fatigue life of deep groove ball bearings is greatly affected by the load. The fatigue life of rolling bearings depends largely on large rolling loads. Therefore, with the increase of load, the large rolling load increases significantly and the fatigue life decreases.
