先來了解一下**基礎(chǔ)的滾珠軸承結(jié)構(gòu)吧—— </p> <p> 滾珠軸承主要包含四個(gè)基本元件：軸承滾珠（ball）、軸承內(nèi)環(huán)（inner ring）、軸承外環(huán)（outer ring）與軸承保持器（cage or retainer）。 </p> <p> 一般工業(yè)用的滾珠軸承滿足AISI52100的標(biāo)準(zhǔn)，軸承滾珠與軸承環(huán)通常是以高鉻鋼制成，洛氏硬度（Rockwell C- scale hardness）約在61-65之間。鋼球球是重要的基礎(chǔ)零部件。山東庫存鋼球服務(wù)放心可靠</p><div style="width:100%;text-align: center;"><img

</p> <p> 鋼球是在安裝到軸承內(nèi)部后使用過程中開裂的，開裂方向均為材料軋制方向。 </p> <p> 鋼球心部存在有明顯的疏松條帶，帶狀碳化物超標(biāo)且表面含有氧、鈣、鎂等異常元素，另外，條帶均有深度，約0.25mm，由此確定鋼球心部存在縮孔殘余，屬于冶金缺點(diǎn)，這也是導(dǎo)致鋼球在使用過程中發(fā)生開裂的主要原因。 </p> <p> 鋼球的淬回火組織過熱使其脆性增大，降低了抗壓強(qiáng)度，使鋼球更容易發(fā)生開裂。 </p> <p> 結(jié)語 </p> <p> 送檢鋼球開裂是在軸承運(yùn)轉(zhuǎn)過程中開裂的，是材料缺點(diǎn)和熱處理缺點(diǎn)兩者共同作用的結(jié)果，屬于缺點(diǎn)開裂；鋼球心部存在縮孔殘余和帶狀碳化物超標(biāo)為主因，熱處理淬、回火組織過熱使鋼球脆性增大也是導(dǎo)致鋼球開裂的原因之一。當(dāng)鋼球尺寸較小或斷口擠壓、磨損較嚴(yán)重時(shí)，無法確定材料軋制方向，也難以進(jìn)行常規(guī)的斷口分析，此時(shí)可以通過金相法，通過觀察缺點(diǎn)形貌與金相組織的關(guān)系找到開裂的主要原因。江蘇小型鋼球來電咨詢鋼球外觀檢測(cè)是鋼球加工過程中不可缺少的過程。</p><div

src="http://tyunfile.71360.com/UploadFile/czfggq/637116691623134766/2950756.jpg"></div><p> 鋼球二次硬化：當(dāng)鋼中含有較多的碳化物形成元素時(shí)，在回火第四階段溫度區(qū)(約為500～550℃)形成合金滲碳體或者特殊碳化物。這些碳化物的析出，將使硬度再次提高，稱為二次硬化形象。 </p> <p> 回火目的：減少或消除淬火應(yīng)力，提高韌性和塑性，獲得硬度、強(qiáng)度、塑性和韌性的適當(dāng)配合，以滿足鋼球的性能要求。 </p> <p> 碳鋼的回火特性： </p> <p> 淬火鋼回火后的力學(xué)性能，常以硬度來衡量。在未完全淬透情況下，沿工件截面硬度差別隨著回火溫度的提高及回火時(shí)間的延長而逐漸減?。辖痄摰幕鼗鹛匦?，基本和碳鋼類似。但對(duì)具有二次硬化現(xiàn)象的鋼則不同，也不能簡(jiǎn)單地用M參數(shù)來表征回火程度。 </p><p> 鋼球設(shè)計(jì)流程： </p> <p> 鋼球球化退火（加熱到750°C）→保溫3小時(shí)→爐冷至600°C出爐空冷至室溫→將鋼球淬入320°C的硝酸鉀鹽浴中→保溫一段時(shí)間→取出空冷→將鋼球加熱到150°C-170°C回火→保溫3小時(shí)左右→取出油冷至室溫。 </p> <p> 球化退火：球化退火是使鋼球中碳化物球化而進(jìn)行的退火工藝。將鋼球加熱到750度，保溫一段時(shí)間，然后緩慢冷卻，得到在鐵素體基體上均勻分布的球狀或顆粒狀碳化物的組織。 </p> <p> <br /> </p> <p> 鋼球經(jīng)空冷所得組織是片層狀珠光體與網(wǎng)狀滲碳體，這種組織硬而脆，不僅難以切削加工，且在以后淬火過程中也容易變形和開裂。而經(jīng)球化退火得到的是球狀珠光體組織，其中的滲碳體呈球狀顆粒，彌散分布在鐵素體基體上，和片狀珠光體相比，不但硬度低，便于切削加工，而且在淬火加熱時(shí)，奧氏體晶粒不易長大，冷卻時(shí)工件變形和開裂小。鋼球可以用在汽車方向盤里。</p><div
