class="box"><p><p> 分析認(rèn)為，鋼球采用水冷淬火，浙江口碑好軸鋼球量大從優(yōu)，溫度分布很不均勻，形成很高的組織應(yīng)力，其表面呈壓應(yīng)力狀態(tài)．內(nèi)部為拉應(yīng)力，內(nèi)部拉應(yīng)力是造成工件斷裂的主要原因。 </p> <p> 此外，軸承鋼球水淬冷卻能力強(qiáng)，浙江口碑好軸鋼球量大從優(yōu)，且工件內(nèi)層狀組織粗大，接近心部處存在較硬的組織，使工件心部韌性差，存在裂紋開裂弊端。工件生產(chǎn)中淬火后未及時(shí)回火，淬火后應(yīng)力很高而沒(méi)有得到消除和釋放，從而導(dǎo)致鋼球開裂損壞。分析認(rèn)為，軸承鋼球淬火開裂與鍛造及熱處理工藝密切相關(guān)。鍛造加熱時(shí)間或溫度控制不當(dāng)，造成鋼球過(guò)熱或過(guò)燒，浙江口碑好軸鋼球量大從優(yōu)，故晶粒粗大，工件韌性下降。另一方面，鋼球中心部位鍛造變形小，冷卻速度也較小，因而該部位再結(jié)晶晶粒粗大，造成鋼球裂紋斷裂**易先在中部發(fā)生。 </p> <p> 綜上分析，提出高碳馬氏體鋼球防止開裂工藝改進(jìn)措施如下： </p> <p> 鍛造。加大鍛造比，嚴(yán)格鍛造工藝控制，防止鍛后心部組織粗大。 </p> <p> 降低軸承鋼球淬火入水溫度，提高出水溫度，可使工件淬火應(yīng)力明顯減小和緩和。 </p> <p> 淬火前增加球化退火，細(xì)化組織，使工件淬火后呈細(xì)針狀(細(xì)片狀．)馬氏體，防止淬火后產(chǎn)生粗大組織。 </p> <p> 淬火后及時(shí)回火，消除淬火應(yīng)力，穩(wěn)定組織，進(jìn)一步去除工件產(chǎn)生開裂的問(wèn)題。 </p> <p> <br /> </p><div style="width:100%;text-align:

</p> <p> 軸承鋼球是球軸承中重要的零部件之一，質(zhì)量的好壞很大程度上影響到軸承的動(dòng)態(tài)性能和使用壽命。軸承振動(dòng)值的降低和壽命的提高與軸承鋼球表面質(zhì)量的提高密不可分...... </p> <p> 軸承鋼球的研磨工藝正在發(fā)生重大革新，由傳統(tǒng)的鑄鐵磨盤更替為樹脂砂輪，以磨代研，在保證軸承鋼球壽命不受影響的前提下**提高了生產(chǎn)效率。 </p> <p> 由于在材料冶金質(zhì)量，鋼球加工工藝和表面強(qiáng)化工藝等方面我國(guó)與日本，瑞典及美國(guó)等先進(jìn)國(guó)家相比有一定的差距，導(dǎo)致鋼球的使用壽命和可靠性同樣存在差距...... </p> <p> 為了提高球軸承中鋼球的使用壽命，軸承鋼球必須具備以下主要特性：高的接觸疲勞強(qiáng)度；表面高的硬度；表面高的耐磨性；高的彈性極限和壓碎負(fù)荷；良好的尺寸穩(wěn)定性；高的表面加工精度。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

軸承鋼球在工作是承受著極大的壓力和磨擦力，所以要求軸承鋼有高而均勻的硬度和耐磨性，以及高的彈性極限。對(duì)軸承鋼的化學(xué)成分的均勻性、非金屬夾雜物的含量和分布、碳化物的分布等要求都十分嚴(yán)格軸承鋼又稱高碳硌鋼，含碳Wc為1%左右，含硌量Wcr為0.5%-1.65%。軸承鋼又分為高碳硌軸承鋼、無(wú)硌軸承鋼、滲碳軸承鋼、不銹軸承鋼、中高溫軸承鋼及防磁軸承鋼六大類。 </p> <p> 應(yīng)用領(lǐng)域：軸承鋼球***用于高速低噪音軸承，自行車、摩托車、汽車、滑軌、萬(wàn)向球、箱包、電子工業(yè)、也可用來(lái)研磨其它介質(zhì)。 </p> <p> 特性：硬度可以達(dá)到HRC62 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img
