根據(jù)宏觀、微觀觀察分析及金相檢驗的結果可以確定： </p> <p> 鋼球是在安裝到軸承內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，帶狀碳化物超標且表面含有氧、鈣、鎂等異常元素，上海質量鋼球性價比出眾，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，這也是導致鋼球在使用過程中發(fā)生開裂的主要原因，上海質量鋼球性價比出眾。 </p> <p> 鋼球的淬回火組織過熱使其脆性增大，降低了抗壓強度，使鋼球更容易發(fā)生開裂。 </p> <p> 結語 </p> <p> 送檢鋼球開裂是在軸承運轉過程中開裂的，是材料缺點和熱處理缺點兩者共同作用的結果，屬于缺點開裂；鋼球心部存在縮孔殘余和帶狀碳化物超標為主因，熱處理淬，上海質量鋼球性價比出眾、回火組織過熱使鋼球脆性增大也是導致鋼球開裂的原因之一。當鋼球尺寸較小或斷口擠壓、磨損較嚴重時，無法確定材料軋制方向，也難以進行常規(guī)的斷口分析，此時可以通過金相法，通過觀察缺點形貌與金相組織的關系找到開裂的主要原因。

鑄造鋼球因材料以及加工工藝的不同，熱處理內外淬透性差，生產處理鋼球內外硬度差別大。 </p> <p> 因為鍛造鋼鐵有高碳錳鉻等合金元素合理搭配，生產熱處理內外淬透性強，內外硬度差別小，還因沖擊值的差別。因此決定鍛球與鑄造球相比更加不破碎。 </p> <p> 鍛造鋼球破碎率小，而鑄造鋼球破碎率大，一般情況鑄造鋼球破碎率在3%，而鍛造鋼球在1%，由于破碎率小，增加了磨機的出粉率，并減少了選礦成本，就提高了磨機生產效率。 </p> <p> 由于我們的鍛造鋼球金相組織是細針狀馬氏體組織，硬度較高，與鑄造鋼球同等耐磨性能下，鍛造鋼球價格遠遠低于鑄造鋼球，研磨成本更低。 </p><div style="width:100%;text-align:

style="text-indent:25px">測量軸承外圈，是為了選配內圈和鋼球，以便于滿足軸承的初始游隙。測量軸承內圈，是為了選配外圈和鋼球，以便于滿足軸承的初始游隙。選擇鋼球：這幾個管子里面的鋼球，公稱尺寸是一樣的，但是因為有公差，為了使每個軸承中的鋼球直徑一致，鋼球根據(jù)實際尺寸又細分成多組，每一組的直徑差很小有些能控制在5微米以內，這是非常精確的了。內外圈合套：通過尺寸檢測，選擇合適的內外圈，套在一起。填鋼球：將內圈推至一側，另一側內外圈之間的間隙就比較大，可以裝入鋼球。均分鋼球：將內圈推回中心位置，再將鋼球均勻地分布于圓周。裝單側保持架：將單側保持架安裝進組裝好的內外圈中。鉚固保持架：安裝另一側保持架，并鉚固，就此完成軸承的組裝過程。軸承的組裝過程你get到了嗎？沒想到吧，軸承這種**常用的標準件的組裝過程竟然是選配組裝的。</p><div
