軸承鋼珠是一種用于工業(yè)生產(chǎn)的零件。屬于軸承的一部分。 </p> <p> 軸承鋼珠制作流程 </p> <p> 伸線（拔絲）：將線材用拉絲機(jī)拉伸至所需要的線徑； </p> <p> 冷鐓（鍛壓）：將拉好的線材置入鋼球冷鐓機(jī)，由機(jī)內(nèi)的鋼模鐓打成球胚； </p> <p> 光球：光球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將冷鐓球胚子加壓銼磨，去除球胚上的外環(huán)帶和兩極點； </p> <p> 軟球：軟球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將光球球胚子銼磨使球胚子磨成所需球徑及表面粗糙度； </p> <p> 熱處理：將球裝入熱處理爐內(nèi)加以滲碳后淬火再回火使球具有一定的滲碳層及硬度，韌性和壓碎負(fù)荷； </p> <p> 硬磨：研磨機(jī)內(nèi)的砂輪圓板將熱處理球胚加壓磨削，以去除球表面的黑色氧化層及修正球的精度； </p> <p> 精研/拋光清洗：精研：將研磨球胚在精研機(jī)內(nèi)精研磨，使球達(dá)到成品所需要的精度和光潔度；拋光清洗：將球倒入拋光滾桶內(nèi)轉(zhuǎn)動并用拋光清洗劑加水清洗使球面清潔光亮； </p> <p> 外觀選別：用人工目測檢查鋼球表面有無任何瑕疵，并用千分尺測量真圓度，批直徑變動量及用表面粗糙度儀檢測表面粗糙度來作為終檢； </p> <p> 包裝：將鋼球/不銹鋼球/軸承鋼球涂上防銹油后裝入紙箱或編織袋后打包。 </p> <p> 出貨：在客戶有要求的前提下，要按照客戶要求進(jìn)行包裝出貨。浙江庫存鋼球廠家直供鋼球根據(jù)加工材料分為軸承鋼球，不銹鋼球，碳鋼球，銅軸承鋼球球，合金球等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

高鉻球的含鉻量是大于等于10.0%。含碳量在1.80%和3.20%之間。根據(jù)國家標(biāo)準(zhǔn),高鉻球硬度必須不小于58hrc,沖擊值應(yīng)大于等于3.0j/cm2。若達(dá)此硬度高鉻球必須用高溫淬火和回火處理。目前國內(nèi)高鉻球淬火有兩種方法包括油淬火和風(fēng)力淬火。如果高鉻球測試硬度低于54HRC，就意味著它沒有經(jīng)過淬火處理。

熱軋鋼球源于前蘇聯(lián)，1956年，邯鋼引進(jìn)國內(nèi)熱軋鋼球生產(chǎn)線，隨著熱軋鋼球原材料的不斷研發(fā)以及生產(chǎn)設(shè)備的不斷改進(jìn)，熱軋鋼球在國際國內(nèi)礦山行業(yè)應(yīng)用均取得了良好效果。 </p> <p> 熱軋鋼球的生產(chǎn)工藝流程如下： </p> <p> 圓鋼棒料入廠檢驗； </p> <p>

</p> <p> 但是拆裝過軸承的朋友并不多，很多剛畢業(yè)的機(jī)械專業(yè)學(xué)生更是一頭霧水！ </p> <p> 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基本元件：軸承滾珠（ball）、軸承內(nèi)環(huán)（inner ring）、軸承外環(huán)（outer

鋼球生產(chǎn)方式一般有鍛造、軋制、半固態(tài)成型及鑄造四大類。由于歷史沿習(xí)及選礦工業(yè)一些特殊的使用條件和綜合環(huán)境、背景，在這些行業(yè)中，鍛造與軋制球占有相當(dāng)大的比例。半固態(tài)成型則具有非常規(guī)鑄造，非簡單壓鑄所能解釋清的特點，以一種似鑄、似鍛，鑄鍛優(yōu)點兼而有之的先進(jìn)技術(shù)所形成的優(yōu)異性能而引起人們的關(guān)注。而鑄造鋼球則以其簡單、靈活、可靠的生產(chǎn)方式，易于實現(xiàn)低投資大規(guī)模生產(chǎn)的擴(kuò)張優(yōu)勢，尤其是當(dāng)**和工程師面對煉鋼爐運(yùn)用各種先進(jìn)工藝和合金成份設(shè)計，發(fā)揮無盡的想象力，去創(chuàng)造一個又一個更新穎、更先進(jìn)的品種，來滿足競爭需要所帶來的成就感，更非常人所能體會。理所當(dāng)然的鑄球的高性價比與持續(xù)發(fā)展的潛力，使之成為當(dāng)今粉碎工業(yè)尤其是水泥粉碎工業(yè)鋼球生產(chǎn)方式中當(dāng)仁不讓的主力軍。
