標準解讀
《GB/T 25763-2024 滾動軸承 汽車變速箱用滾針軸承》與《GB/T 25763-2010 滾動軸承 汽車變速箱用滾針軸承》相比，主要在以下幾個方面進行了更新和調(diào)整：
首先，在標準的適用范圍上有所擴展。新版本不僅涵蓋了原有型號的滾針軸承，還增加了對新型號滾針軸承的要求，以適應(yīng)近年來汽車工業(yè)技術(shù)的發(fā)展需求。
其次，對于材料的要求更加嚴格。2024版標準中明確了更多種類的材料選項，并且提高了對材料性能的具體要求，比如硬度、耐腐蝕性等指標都有所提升，旨在提高產(chǎn)品的使用壽命和可靠性。
再者，關(guān)于制造精度的規(guī)定也更為詳細。新版標準細化了尺寸公差、形位公差等方面的要求，確保了產(chǎn)品的一致性和互換性，有利于提高整個行業(yè)的標準化水平。
此外，檢測方法和技術(shù)條件也有相應(yīng)更新。為了更好地保證產(chǎn)品質(zhì)量，《GB/T 25763-2024》引入了一些先進的測試手段和技術(shù)規(guī)范，如改進后的疲勞壽命試驗方法等，這有助于更準確地評估軸承的實際工作性能。
最后，在包裝、標志以及運輸儲存條件等方面也做了適當修改和完善，增強了指導(dǎo)性和操作性，便于企業(yè)實施及執(zhí)行。
