前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T25763—2010《滾動(dòng)軸承汽車變速箱用滾針軸承》，與GB/T25763—2010相

比，除結(jié)構(gòu)調(diào)整和編輯性改動(dòng)外，主要技術(shù)變化如下：

a）更改了適用范圍（見第1章，2010年版的第1章）；

b）增加了推力滾針軸承組件等部分滾針軸承分類（見第5章）；

c）增加了推力滾針軸承組件等部分軸承的代號(hào)方法和代號(hào)示例（見6.2.3、6.4）；

d）增加了推力滾針軸承組件等部分軸承的結(jié)構(gòu)型式（見7.6）；

e）增加了“外形尺寸”一章（見第8章）；

f）更改了沖壓外圈滾針軸承外徑公差的尺寸范圍（見表8，2010年版的表7）；

g）增加了推力滾針軸承組件的公差（見表9、表10）；

h）更改了清潔度控制指標(biāo)及測試濾膜孔徑尺寸（見9.7、10.6，2010年版的8.7、9.6）。
