本實(shí)用新型的靜音鋼球，采用砂輪磨削法制造，使鋼球表面磨削形成細(xì)小凹槽，這些細(xì)小凹槽可作為自然儲油點(diǎn)，使鋼球的表面與軸承滾道摩擦?xí)r一直有潤滑油潤滑，這樣使鋼球的性能有很大的提高，特別是有很好的靜音效果。本實(shí)用新型的靜音鋼球的各項(xiàng)指標(biāo)達(dá)到G5級標(biāo)準(zhǔn)，有些指標(biāo)達(dá)到G3標(biāo)準(zhǔn)。

style="text-indent:25px">軸承是機(jī)械設(shè)備中常用的零部件，你眼見到軸承這種零件的時(shí)候是不是也納悶過，鋼球是怎么裝進(jìn)去的呢？軸承是一種看上去很簡單，其實(shí)很不簡單的零部件，以一般的球軸承為例，其實(shí)他*包含軸承內(nèi)外圈/ 鋼球/

</p> <p> 鋼球的制造方法會產(chǎn)生影響：軋制及鍛打的鋼球其組織致密，故密度大，鑄造的鑄鋼球、鑄鐵球或鑄造合金球等的組織致密，相對密度小一些。 </p> <p> 鋼球金相組織會產(chǎn)生影響：馬氏體、奧氏體、貝氏體、鐵素體等不同晶體結(jié)構(gòu)下密度也不相同，對結(jié)晶細(xì)度也有影響。 </p><p> 鋼球回火后的冷卻 </p> <p> 回火后鋼球在空氣中冷卻。以防止開裂。回火后應(yīng)進(jìn)行油冷，以回火脆性。在防止開裂條件下，可進(jìn)行油冷或水冷，然后進(jìn)行一次低溫補(bǔ)充回火，以消除快冷產(chǎn)生的內(nèi)應(yīng)力。 </p> <p> 鋼球表面熱處理： </p> <p> 感應(yīng)加熱表面淬火： </p> <p> 定義：是采用一定方法使工件表面產(chǎn)生一定頻率的感應(yīng)電流，將零件表面迅速加熱，然后迅速淬火冷卻的一種熱處理操作方法。 </p> <p> 原理：如圖所示，電磁感應(yīng)產(chǎn)生同頻率的感應(yīng)電流即渦流。渦流在工件截面上的分布是不均勻的，心部幾乎等于零，而表面電流密度極大，稱為“集膚效應(yīng)”，頻率愈高，電流密度極大的表面層愈薄。依靠這種電流和工件本身的電阻，使工件表面迅速加熱到淬火溫度，而心部溫度仍接近室溫，然后立即噴水冷卻，使工件表面淬硬。鋼球外觀檢測是鋼球加工過程中不可缺少的過程。</p><div
